what were the main causes of the civil war essay

What Were the Top Causes of the Civil War?

  • M.A., History, University of Florida
  • B.A., History, University of Florida

The question “What caused the U.S. Civil War?” has been debated since the horrific conflict ended in 1865. As with most wars, however, there was no single cause.

The Civil War erupted from a variety of longstanding tensions and disagreements about American life and politics. For nearly a century, the people and politicians of the Northern and Southern states had been clashing over the issues that finally led to war: economic interests, cultural values, the power of the federal government to control the states, and, most importantly, slavery in American society.

While some of these differences might have been resolved peacefully through diplomacy, the institution of slavery was not among them. With a way of life steeped in age-old traditions of white supremacy and a mainly agricultural economy that depended on the labor of enslaved people, the Southern states viewed enslavement as essential to their very survival.

Slavery in the Economy and Society

At the time of the Declaration of Independence in 1776, the enslavement of people not only remained legal in all 13 British American colonies, but it also continued to play a significant role in their economies and societies.

Before the American Revolution, the institution of slavery in America had become firmly established as being limited to persons of African ancestry. In this atmosphere, the seeds of white supremacy were sown.

Even when the U.S. Constitution was ratified in 1789, very few Black people and no enslaved people were allowed to vote or own property.

However, a growing movement to abolish slavery had led many Northern states to enact abolitionist laws and abandon enslavement. With an economy based more on industry than agriculture, the North enjoyed a steady flow of European immigrants. As impoverished refugees from the potato famine of the 1840s and 1850s, many of these new immigrants could be hired as factory workers at low wages, thus reducing the need for enslaved people in the North.

How Slavery Spread Through the South

In the Southern states, longer growing seasons and fertile soils had established an economy based on agriculture fueled by sprawling plantations owned by White people that depended on enslaved people to perform a wide range of duties.

When Eli Whitney invented the cotton gin in 1793, cotton became very profitable. This machine was able to reduce the time it took to separate seeds from the cotton. At the same time, the increase in the number of plantations willing to move from other crops to cotton created an even greater need for enslaved people. The Southern economy became a one-crop economy, depending on cotton and, therefore, on enslaved people.

Though it was often supported throughout the social and economic classes, not every White Southerner enslaved people. The population of the pro-slavery states was around 9.6 million in 1850 and only about 350,000 were enslavers. This included many of the wealthiest families, several of whom owned large plantations. At the start of the Civil War , at least 4 million enslaved people were forced to live and work on the Southern plantations.

Conflict Between the North and the South

In contrast, industry ruled the economy of the North and less emphasis was on agriculture, though even that was more diverse. Many Northern industries were purchasing the South's raw cotton and turning it into finished goods.

This economic disparity also led to irreconcilable differences in societal and political views.

In the North, the influx of immigrants—many from countries that had long since abolished slavery—contributed to a society in which people of different cultures and classes lived and worked together.

The South, however, continued to hold onto a social order based on white supremacy in both private and political life, not unlike that under the rule of racial apartheid that persisted in South Africa for decades .

In both the North and South, these differences influenced views on the powers of the federal government to control the economies and cultures of the states.

States and Federal Rights

Since the time of the American Revolution , two camps emerged when it came to the role of government. Some people argued for greater rights for the states and others argued the federal government needed to have more control.

The first organized government in the U.S. after the Revolution was under the Articles of Confederation. The 13 states formed a loose Confederation with a very weak federal government. However, when problems arose, the weaknesses of the Articles caused the leaders of the time to come together at the Constitutional Convention and create, in secret, the U.S. Constitution .

Strong proponents of states' rights like Thomas Jefferson and Patrick Henry were not present at this meeting. Many felt that the new Constitution ignored the rights of states to continue to act independently. They felt that the states should still have the right to decide if they were willing to accept certain federal acts.

This resulted in the idea of nullification , whereby the states would have the right to rule federal acts unconstitutional. The federal government denied states this right. However, proponents such as John C. Calhoun —who resigned as vice president to represent South Carolina in the Senate—fought vehemently for nullification. When nullification would not work and many of the Southern states felt that they were no longer respected, they moved toward thoughts of secession.

Pro-Slavery States and Free States

As America began to expand—first with the lands gained from the Louisiana Purchase and later with the Mexican War —the question arose of whether new states would be pro-slavery states or free states. An attempt was made to ensure that equal numbers of free states and pro-slavery states were admitted to the Union, but over time this proved difficult.

The Missouri Compromise passed in 1820. This established a rule that prohibited enslavement in states from the former Louisiana Purchase north of the latitude 36 degrees 30 minutes, except for Missouri.

During the Mexican War, the debate began about what would happen with the new territories the U.S. expected to gain upon victory. David Wilmot proposed the Wilmot Proviso in 1846, which would ban enslavement in the new lands. This was shot down amid much debate.

The Compromise of 1850 was created by Henry Clay and others to deal with the balance between pro-slavery states and free states. It was designed to protect both Northern and Southern interests. When California was admitted as a free state, one of the provisions was the Fugitive Slave Act . This held individuals responsible for harboring freedom-seeking enslaved people, even if they were located in free states.

Tensions Around Slavery Rise

The  Kansas-Nebraska Act of 1854 was another issue that further increased tensions. It created two new territories that would allow the states to use popular sovereignty to determine whether they would be free states or pro-slavery states. The real issue occurred in Kansas where pro-slavery Missourians, called "Border Ruffians," began to pour into the state in an attempt to force it toward slavery.

Problems came to a head with a violent clash at Lawrence, Kansas. This caused it to become known as " Bleeding Kansas ." The fight even erupted on the floor of the Senate when anti-slavery proponent Sen. Charles Sumner of Massachusetts was beaten on the head by South Carolina Sen. Preston Brooks.

The Abolitionist Movement

Increasingly, Northerners became more polarized against enslavement. Sympathies began to grow for abolitionists and against enslavement and enslavers. Many in the North came to view enslavement as not just socially unjust, but morally wrong.

The abolitionists came with a variety of viewpoints. People such as William Lloyd Garrison and Frederick Douglass wanted immediate freedom for all enslaved people. A group that included Theodore Weld and Arthur Tappan advocated for emancipating enslaved people slowly. Still others, including Abraham Lincoln, simply hoped to keep slavery from expanding.

Many events helped fuel the cause for abolition in the 1850s.  Harriet Beecher Stowe  wrote " Uncle Tom's Cabin ," a popular novel that opened many eyes to the reality of enslavement. The Dred Scott Case  brought the issues of enslaved peoples' rights, freedom, and citizenship to the Supreme Court.

Additionally, some abolitionists took a less peaceful route to fighting against slavery. John Brown and his family fought on the anti-slavery side of "Bleeding Kansas." They were responsible for the Pottawatomie Massacre, in which they killed five settlers who were pro-slavery. Yet, Brown's best-known fight would be his last when the group attacked Harper's Ferry in 1859, a crime for which he would hang.

The Election of Abraham Lincoln

The politics of the day were as stormy as the anti-slavery campaigns. All of the issues of the young nation were dividing the political parties and reshaping the established two-party system of Whigs and Democrats.

The Democratic Party was divided between factions in the North and South. At the same time, the conflicts surrounding Kansas and the Compromise of 1850 transformed the Whig Party into the Republican Party (established in 1854). In the North, this new party was seen as both anti-slavery and for the advancement of the American economy. This included the support of industry and encouraging homesteading while advancing educational opportunities. In the South, Republicans were seen as little more than divisive.

The presidential election of 1860 would be the deciding point for the Union. Abraham Lincoln represented the new Republican Party and Stephen Douglas , the Northern Democrat, was seen as his biggest rival. The Southern Democrats put John C. Breckenridge on the ballot. John C. Bell represented the Constitutional Union Party, a group of conservative Whigs hoping to avoid secession.

The country's divisions were clear on Election Day. Lincoln won the North, Breckenridge the South, and Bell the border states. Douglas won only Missouri and a portion of New Jersey. It was enough for Lincoln to win the popular vote, as well as 180 electoral votes .

Even though things were already near a boiling point after Lincoln was elected, South Carolina issued its "Declaration of the Causes of Secession " on December 24, 1860. They believed that Lincoln was anti-slavery and in favor of Northern interests.

Southern States Begin Seceding From the Union

President James Buchanan's administration did little to quell the tension or stop what would become known as " Secession Winter ." Between Election Day and Lincoln's inauguration in March, seven states seceded from the Union: South Carolina, Mississippi, Florida, Alabama, Georgia, Louisiana, and Texas.

In the process, the South took control of federal installations, including forts in the region, which would give them a foundation for war. One of the most shocking events occurred when one-quarter of the nation's army surrendered in Texas under the command of General David E. Twigg. Not a single shot was fired in that exchange, but the stage was set for the bloodiest war in American history.

Causes of the Civil War

  • The U.S. Civil War stemmed from a complex web of tensions over economic interests, cultural values, federal government power, and most significantly, the institution of slavery.
  • While the North and South clashed over these issues for decades, the Southern states, rooted in white supremacy and reliant on enslaved labor for their agricultural economy, viewed enslavement as indispensable to their way of life—thus setting the stage for conflict.
  • The election of Abraham Lincoln in 1860, representing the anti-slavery Republican Party, triggered Southern states' secession from the Union, marking a point of no return and leading to the outbreak of the bloodiest war in American history.

There were various causes for the civil war to take place. Some causes were cultural, while some were political, others were economic. The Union between the north and the south was split based on several important factors. Although the major cause was slavery, when such a thing entered into the political sphere, the problem came to the public view, which now required an immediate solution.

The economic differences between the south and the north were tremendous. The south was labour intensive because it largely depended on agriculture. It mainly produced cotton which required considerable human resources. On the other hand, the north had products of innovative industries and relied on the manufacturing-based economy. The north never required such huge amounts of the labour force. This difference contributed to the conflict.

The cultural differences between these two states were also huge. The north had a cosmopolitan society were life moved very fast. There was diversification in the infrastructure, and society was very modern. The south was the opposite in this respect. Here, the life of the people was slow-paced, and society was homogenous. The people in society were orthodox and loved their deep-rooted culture. Thus the roots of the civil war were largely colonial.

The two main notions that were in a tug of war was a radical abolition of slavery and pro-slavery. The north and the south were tied in conflict whether the states could decide what had to be done with slavery. William Lloyd Garrison was the voice of anti-slavery movement in the north, and he published “The Liberator”, which reached out to people far and wide. He was never in favour of compromise and founded the “New England Anti-Slavery Society” in the year 1832.

Frederick Douglass became another famous leader of this movement, who was born a slave but later escaped to America. He was born in Maryland, which was a pro-slavery nation. He was an advisor President Abraham Lincoln, who also propounded the anti-slavery movement. President Lincoln, who won the election in the year 1860, was the first Republican president. He sincerely fought for the abolition of slavery and made amendments to the constitution. The south was dissatisfied with these steps. Seven states in the south supported slavery whole-heartedly. These states that were pro-slavery formed the Confederate States of America. However, this body was not legitimate in the eyes of the north and Lincoln.

The idea of slavery had always kept the states divided. This war saw the victory of the north when president Lincoln made an executive order to free all the slaves. The Union Army, the largest organized army in America, captured all states, and finally, all the states were unified against slavery. This unification was through a common goal; to capture as many territories as possible and to make the slaves free of their bondage. This victory, however, came at a huge cost. This war saw a huge loss of lives, and the count reached almost 625000.

Short Essay on Causes of the Civil War Essay 150 Words in English

Short Essay on Causes of the Civil War Essay is usually given to classes 1, 2, 3, 4, 5, and 6.

In the history of America, the civil war had contributed to many dark pages. This war was fought to free the long-lived reign of slavery. The northern and the southern states, who sat on two opposite spots of the spectrum about the subject of slavery, met in the battlefield. The roots of this war were deep and could be seen from a cultural, economic and political point of views.

The gap between the two states, concerning the economy, culture and politics were tremendous. The north was a more prosperous nation, endowed with wealth. The life of people here was fast-paced; they had more money than they could keep. The agricultural south had an orthodox society where life was sluggish. The south supported slavery whole-heartedly, as the demand for labour here was huge. It was agriculture-based that required human resources. The north had the industrial base, which required more machines than men. These differences were largely at play behind the civil war.

From States’ Rights to Slavery: What Caused the American Civil War?

The Northern and Southern sections of the United States developed along different lines. The South remained a predominantly agrarian economy while the North became more and more industrialized. Different social cultures and political beliefs developed. All of this led to disagreements on issues such as taxes, tariffs and internal improvements as well as states’ rights versus federal rights. At the crux of it all, however, was the fight over slavery.

The burning issue that led to the disruption of the union was the debate over the future of slavery. That dispute led to secession, and secession brought about a war in which the Northern and Western states and territories fought to preserve the Union, and the South fought to establish Southern independence as a new confederation of states under its own constitution.

The agrarian South utilized slaves to tend its large plantations and perform other duties. On the eve of the Civil War, some 4 million Africans and their descendants toiled as slave laborers in the South. Slavery was interwoven into the Southern economy even though only a relatively small portion of the population actually owned slaves. Slaves could be rented or traded or sold to pay debts. Ownership of more than a handful of slaves bestowed respect and contributed to social position, and slaves, as the property of individuals and businesses, represented the largest portion of the region’s personal and corporate wealth, as cotton and land prices declined and the price of slaves soared.

The states of the North, meanwhile, one by one had gradually abolished slavery. A steady flow of immigrants, especially from Ireland and Germany during the potato famine of the 1840s and 1850s, insured the North a ready pool of laborers, many of whom could be hired at low wages, diminishing the need to cling to the institution of slavery.

Th e Dred Scott Decision

Dred Scott was a slave who sought citizenship through the American legal system, and whose case eventually ended up in the Supreme Court. The famous Dred Scott Decision in 1857 denied his request stating that no person with African blood could become a U.S. citizen. Besides denying citizenship for African-Americans, it also overturned the Missouri Compromise of 1820, which had restricted slavery in certain U.S. territories.

States’ Rights

States’ Rights refers to the struggle between the federal government and individual states over political power. In the Civil War era, this struggle focused heavily on the institution of slavery and whether the federal government had the right to regulate or even abolish slavery within an individual state. The sides of this debate were largely drawn between northern and southern states, thus widened the growing divide within the nation.

Abolitionist Movement

By the early 1830s, those who wished to see that institution abolished within the United States were becoming more strident and influential. They claimed obedience to “higher law” over obedience to the Constitution’s guarantee that a fugitive from one state would be considered a fugitive in all states. The fugitive slave act along with the publishing of Harriet Beecher Stowe’s Uncle Tom’s Cabin helped expand the support for abolishing slavery nationwide.

Harriet Beecher S towe’s Uncle Tom’s Cabin

Harriet Beecher Stowe’s anti-slavery novel Uncle Tom’s Cabins was published in serial form in an anti-slavery newspaper in 1851 and in book format in 1852. Within two years it was a nationwide and worldwide bestseller. Depicting the evils of slavery, it offered a vision of slavery that few in the nation had seen before. The book succeeded at its goal, which was to start a wave of anti-slavery sentiment across the nation. Upon meeting Stowe, President Lincoln remarked, “So you’re the little woman who wrote the book that started this great war.”

The Underground Railroad

Some abolitionists actively helped runaway slaves to escape via “the Underground Railroad,” and there were instances in which men, even lawmen, sent to retrieve runaways were attacked and beaten by abolitionist mobs. To the slave holding states, this meant Northerners wanted to choose which parts of the Constitution they would enforce, while expecting the South to honor the entire document. The most famous activist of the underground railroad was Harriet Tubman , a nurse and spy in the Civil War and known as the Moses of her people.

The Missouri Compromise

Additional territories gained from the U.S.–Mexican War of 1846–1848 heightened the slavery debate. Abolitionists fought to have slavery declared illegal in those territories, as the Northwest Ordinance of 1787 had done in the territory that became the states of Ohio, Indiana, Illinois, Michigan and Wisconsin. Advocates of slavery feared that if the institution were prohibited in any states carved out of the new territories the political power of slaveholding states would be diminished, possibly to the point of slavery being outlawed everywhere within the United States. Pro- and anti-slavery groups rushed to populate the new territories.

In Kansas, particularly, violent clashes between proponents of the two ideologies occurred. One abolitionist in particular became famous—or infamous, depending on the point of view—for battles that caused the deaths of pro-slavery settlers in Kansas. His name was John Brown. Ultimately, he left Kansas to carry his fight closer to the bosom of slavery.

The Raid On Harpers Ferry

On the night of October 16, 1859, Brown and a band of followers seized the federal arsenal at Harpers Ferry, Virginia (now West Virginia), in what is believed to have been an attempt to arm a slave insurrection. (Brown denied this at his trial, but evidence indicated otherwise.) They were dislodged by a force of U.S. Marines led by Army lieutenant colonel Robert E. Lee.

Brown was swiftly tried for treason against Virginia and hanged. Southern reaction initially was that his acts were those of a mad fanatic, of little consequence. But when Northern abolitionists made a martyr of him, Southerners came to believe this was proof the North intended to wage a war of extermination against white Southerners. Brown’s raid thus became a step on the road to war between the sections.

T he Election Of Abraham Lincoln

Exacerbating tensions, the old Whig political party was dying. Many of its followers joined with members of the American Party (Know-Nothings) and others who opposed slavery to form a new political entity in the 1850s, the Republican Party. When the Republican candidate Abraham Lincoln won the 1860 presidential election, Southern fears that the Republicans would abolish slavery reached a new peak. Lincoln was an avowed opponent of the expansion of slavery but said he would not interfere with it where it existed.

Southern Secession

That was not enough to calm the fears of delegates to an 1860 secession convention in South Carolina. To the surprise of other Southern states—and even to many South Carolinians—the convention voted to dissolve the state’s contract with the United States and strike off on its own.

South Carolina had threatened this before in the 1830s during the presidency of Andrew Jackson , over a tariff that benefited Northern manufacturers but increased the cost of goods in the South. Jackson had vowed to send an army to force the state to stay in the Union, and Congress authorized him to raise such an army (all Southern senators walked out in protest before the vote was taken), but a compromise prevented the confrontation from occurring.

Perhaps learning from that experience the danger of going it alone, in 1860 and early 1861 South Carolina sent emissaries to other slave holding states urging their legislatures to follow its lead, nullify their contract with the United States and form a new Southern Confederacy. Six more states heeded the siren call: Mississippi, Florida, Alabama, Georgia, Louisiana, and Texas. Others voted down secession—temporarily.

Fort Sumter

On April 10, 1861, knowing that resupplies were on their way from the North to the federal garrison at Fort Sumter in the harbor of Charleston, South Carolina, provisional Confederate forces in Charleston demanded the fort’s surrender. The fort’s commander, Major Robert Anderson, refused. On April 12, the Confederates opened fire with cannons. At 2:30 p.m. the following day, Major Anderson surrendered.

War had begun. Lincoln called for volunteers to put down the Southern rebellion. Virginia, Arkansas, North Carolina and Tennessee, refusing to fight against other Southern states and feeling that Lincoln had exceeded his presidential authority, reversed themselves and voted in favor of session. The last one, Tennessee, did not depart until June 8, nearly a week after the first land battle had been fought at Philippi in Western Virginia. (The western section of Virginia rejected the session vote and broke away, ultimately forming a new, Union-loyal state, West Virginia. Other mountainous regions of the South, such as East Tennessee, also favored such a course but were too far from the support of Federal forces to attempt it.)

what were the main causes of the civil war essay

The American Civil War (1861-65) is one of the most studied periods in American history, and the conflict remains the bloodiest in American history, claiming the lives of roughly 20% of men aged between 18 and 40.

The folklore and mythology surrounding the Civil War have captured the imaginations of generations since, and the Confederate flag remains a controversial and politically powerful symbol today.

But why did America – the land of hope and dreams – erupt into such a destructive and dramatic civil war?

Following the end of the American War of Independence in 1783, the newly independent United States developed its own political structures and constitution. It also began to expand rapidly, purchasing large swathes of land from Mexico and France. As it became a bigger entity, more and more regional disparities became clear.

Not only was climate and time zone completely different between north and south and east and west, so too was the backbone of these economies. The South relied on agriculture, the West had struck gold, and the North was rapidly industrializing. These differences increasingly began to cause political and cultural tensions.

A long-standing controversy

One such tension was on the subject of slavery: a key cause of the American Civil War. The Unionist North objected to the enslavement of black people, seeing it as incompatible with the idea of a republic, and with the new constitution. By 1804, all Northern states had taken significant measures to outlaw slavery.

In contrast, the South defended slavery – not least because it was the bedrock of their society and way of life. In states where cotton, sugar and tobacco were not only extremely profitable but formed their economic core, abolishing slavery would fundamentally change the way the world worked.

Many in the South were not simply afraid for their livelihoods, but for their lives. There was a very real paranoia about newly emancipated slaves rising up in justifiable anger and hurting or killing them. Whilst this may sound dramatic, their fear was not entirely unfounded. Large numbers of whites were killed following the emancipation of slaves in Haiti.

Whilst slavery was not the only cause of these tensions, debates on the subject fed into other economic, social and political tensions too.

State vs Federal Government

Southern states felt increasingly that their individual autonomy was being encroached on. They wanted the right to abolish federal laws they did not agree with, and increasingly began to use the threat of secession – the leaving of the Union – against the North.

In short, the South was keen to maintain agency and power as individual states, rather than completely acquiesce to central government, which many in the South felt did not represent their interests or reflect their economy.

Equally, people believed the population of Northern states was growing much faster than that in the Southern states. A fear of being a minority, and therefore losing some of their political clout, also became a driving factor.

This became further entrenched as a belief by the election of Abraham Lincoln as 16 th President of the United States. Lincoln’s votes came exclusively from the North and West – not a single Southern state voted for Lincoln to become President. In fact, he was not even on their ballot papers.

This sense of exclusion and lack of power further bolstered political divisions and the Southern states’ desire to regain some agency over their lives.

Territorial Expansion

It was not just the lack of election of Lincoln that was the problem – it was what he represented. At this point, large swathes of the mountainous Western states were almost unsettled by whites, with only a few prospectors looking for gold or oil. The frontiers were pushing ever further into these territories.

Lincoln’s election proved to be the point of no return. In December 1860, South Carolina formally seceded from the Union, and in the next two months, Mississippi, Florida, Alabama, Georgia, Louisiana and Texas followed.

Several states mentioned the failure of federal government in their duty to ‘slaveholding states’, arguing it was their right to hold slaves.

In his inaugural address, Lincoln declared the union to be permanently binding, and secession to be void. Shortly after, Union and Confederate forces clashed for the first time at the Battle of Fort Sumter in April 1861.

Resolution?

According to Lincoln, the American Civil War was always about unity, yet slavery has become recognised as one of the core causes of the war, even if political rhetoric suggests otherwise. A panel of American historians neatly summarised this, saying whilst slavery was a key cause of disunity, it was disunity which was the catalyst to war.

The Thirteenth Amendment was eventually passed by Congress in January 1865, and ratified in December the same year, which outlawed slavery, making emancipation legal and binding. Three million slaves were emancipated by this, yet their post-emancipation status was unclear.

However, slavery may have ended in name, but in reality segregation and discrimination was still enshrined in attitudes and law in many Southern states. The passing of the Jim Crow laws in the 1870s ensured that racial discrimination lived on.

Causes of the American Civil War

A common assumption to explain the cause of the American Civil War was that the North was no longer willing to tolerate slavery as being part of the fabric of US society and that the political power brokers in Washington were planning to abolish slavery throughout the Union. Therefore for many people slavery is the key issue to explain the causes of the American Civil War. However, it is not as simple as this and slavery, while a major issue, was not the only issue that pushed American into the ‘Great American Tragedy’. By April 1861 , slavery had become inextricably entwined with state rights, the power of the federal government over the states, the South’s ‘way of life’ etc. – all of which made a major contribution to the causes of the American Civil War.

Portrait of Abraham Lincoln

By 1860 America could not be seen as being a homogenous society. Clearly defined areas could be identified that had different outlooks and different values. This was later to be seen in the North versus South divide that created the two sides in the war.

The South was an agricultural region where cotton and tobacco were the main backbone to the region’s economic strength. The area relied on exports to markets in Western Europe and the class structure that could be found in the UK, for example, was mimicked in the southern states. The local plantation owner was a ‘king’ within his own area and locals would be deferential towards such men. The whole structure was portrayed in ‘Gone With The Wind’; a strictly Christian society that had men at the top while those underneath were expected and required to accept their social status. Social advancement was possible but invariably it was done within the senior families of a state, who were the economic, political and legal brokers of their state on behalf of the people in that state.

Within this structure was the wealth that these families had accrued. It cannot be denied that a huge part of this wealth came from the fact that the plantation owners oriented the work on their plantations around slave labour. As abhorrent as it may be to those in the C21st, slavery was simply seen as part of the southern way of life. Without slavery, the economic clout of these premier families would have been seriously dented and those they employed and paid – local people who would have recognised how important the local plantation owner was to their own well-being – simply accepted this as ‘how it is’. When the dark clouds of war gathered in 1860-61, many in the South saw their very way of life being threatened. Part of that was slavery but it was not the only part.

The North was almost in complete contrast to the South. In the lead up to April 1861, the North was industrialising at a very fast rate. Entrepreneurs were accepted and, in fact, were seen as being vital to the further industrial development of America. You did not have to stay in your social place and social mobility was common. For example, Samuel Colt was born in Connecticut into a relatively poor background. He had an inauspicious start to his life but ended up a very rich man who left his wife $15 million in his will. Whether he could have done this in the South is a moot topic. It was always possible but most of America’s premier entrepreneurs based themselves in the North where the straitjacket of social class was weaker. Cornelius Vanderbilt is another example.

Whether a man who came from the Netherlands could have forced his way into the social hierarchy of the South is again a question open to debate. The North was also a cosmopolitan mixture of nationalities and religions – far more so than the South. There can be little doubt that there were important groups in the North that were anti-slavery and wanted its abolition throughout the Union. However, there were also groups that were ambivalent and those who knew that the North’s economic development was based not only on entrepreneurial skills but also on the input of poorly paid workers who were not slaves but lived lives not totally removed from those in the South. While they had their freedom and were paid, their lifestyle was at best very harsh.

While the two sides that made up the American Civil War were apart in many areas, it became worse when the perception in the South was that the North would try to impose its values on the South.

In 1832, South Carolina passed an act that declared that Federal tariff legislation of 1828 and 1832 could not be enforced onto states and that after February 1 st 1833 the tariffs would not be recognised in the state. This brought South Carolina into direct conflict with the Federal government in Washington DC. Congress pushed through the Force Bill that enabled the President to use military force to bring any state into line with regards to implementing Federal law. On this occasion the threat of military force worked. People in South Carolina vowed, however, it would be the last time. 

Slavery and the American Civil War

It was now that slavery became mixed up with state rights – just how much power a state had compared to federal authority. State rights became intermingled with slavery. The key issue was whether slavery would be allowed in the newly created states that were joining the Union. This dispute further developed with the ‘Louisiana Purchase’ of 1803 whereby Kansas, among others, was purchased by the federal government. Kansas was officially opened to settlement in 1854 and there was a rush to settle in the state between those who supported slavery and those who opposed it. The state became a place of violence between the two groups and Kansas got the nickname ‘Bleeding Kansas’ in recognition of what was going on there. However on January 29 th 1861, Kansas was admitted to the Union as a slave-free state. Many in the traditional slave states saw this as the first step towards abolishing slavery throughout the Union and thus the destruction of the southern way of life.

When South Carolina seceded from the Union on December 20 th 1860, the first state to do so, it was a sign that the state no longer felt part of the United States of America and that America as an entity was being dominated by a federal government ensconced in the views of the North. Whether this was true or not, is not relevant as it was felt to be true by many South Carolinians. The secession of South Carolina pushed other southern states into doing the same. With such a background of distrust between most southern states and the government in Washington, it only needed one incident to set off a civil war and that occurred at Fort Sumter in April 1861.

On the Civil War’s Causes

By judy giesberg | may 2, 2017 | comments 0 comment.

In the seven years we’ve been in print, the Journal of the Civil War Era has published a number of essays focused on Civil War causation. I turn to a number of these when I teach the Civil War and I have actually advised others—people I’ve met on the sidelines of soccer fields, when walking the dog in my neighborhood, or chatting with a parent at back-to-school night—to take a look for themselves. Indeed, in our second issue published in June 2011, we published Frank Towers’ “Partisans, New History, and Modernization: The Historiography of the Civil War’s Causes, 1861-2011.”

In the essay, Towers identifies the origins of the debate about what caused the Civil War in the war generation of partisans—people like Alexander Stephens and Jefferson Davis, on the one side, and William Seward, among others, on the other side—men who, according to Towers, were motivated by their “obsession with the protagonists’ questions of who was to blame for dissolving the Union and why.” [1] These men were followed by generations of professionally trained historians who returned to the question of what caused the Civil War, each time with new sources and methods at their disposal and moved by a willingness to follow the evidence where it took them.

Today is a great day to go back and read Towers’ essay—or to recommend it to someone else. And, perhaps you’d like to recommend something else, from the pages of JCWE or elsewhere? Our back issues are available through ProjectMuse and are part of the benefits of membership in the Society of Civil War Historians .

The Main Cause of the Civil War Essay

Introduction

There are still debates in academia and the public sphere about what was the cause of the American Civil War. Some see the Civil War as a moral crusade against the South’s abhorrent practice of slave ownership, while others see it as the South’s rebellion against the government that violated states’ rights. While it is reasonable to assert that such a complex and multifaceted phenomenon was brought about by many interlinking causes and effects, in the end, all of them lead back to slavery. Slave ownership rights that the Confederate states tried to protect were the root cause of the conflict.

There is ample evidence to suggest that slave ownership and slave-based commerce were precisely the “states’ rights” that were violated by the Union. The initial seven states to secede were in direct opposition to the abolition of slavery, and they have proclaimed as much. Texas, upon separating, has deemed the notion of abolition to be “the debasing doctrine of the equality of all men, irrespective of race and color—a doctrine at war with nature, in opposition to the experience of mankind, and violation of the plainest revelations of Divine Law” (Dew, p. 18). Wealthy slave owners backed these religious public proclamations of Southern diplomats. Slave prices in the antebellum South reflected the slave owners’ apprehension of the possible consequences of Lincoln’s presidency. The prices have dropped by approximately a third even before any significant hostilities (Calomiris and Pritchett, p. 2). The slave market was tied to the political discussion of that time, which supports the assertion that slavery was the driving force behind Confederate politics.

Furthermore, the anti-abolition and pro-secession narratives were supported by white supremacy with religious roots. In a famous Cornerstone Speech, the Confederate Vice President Alexander H. Stevens proclaimed that the Confederacy is founded “[…] upon the great truth that the negro is not equal to the white man; that slavery subordination to the superior race is his natural and normal condition” (Cleveland and Stephens, p. 721). This “great truth” is supported by the religious imagery of God, the Creator. A particular part of his speech appeals to God’s decision: “[f]or His purposes, He has made one race to differ from another.” That divine order is not to be questioned, as “we know that it is best, not only for the superior but for the inferior race, that it should be so” (Cleveland and Stephens, p. 723). These beliefs would later crystallize into Jim Crow laws and racial segregation in the Deep South.

Although the institution of slavery itself was the figurative apple of discord during the Civil War, another significant political factor was economics, specifically the cotton trade. The slave labor used to make cotton was a force that kept the prices down, and American cotton was exported to many other nations, where the local workforce processed it. The abolition of slavery would mean an increase in prices, a possible slump in production, and a need to find other cheap sources of cotton, which might have provoked global support for the Confederacy.

The fear of such support was an incentive for the Union diplomats to diminish the importance of the conflict and dub it a “domestic insurrection”, while even going as far as to deny their intention of abolishing slavery altogether (Sandy and Molloy, p. 27). They went even further as the war broke out, soliciting support from prominent European military figures and sowing threats of retaliation should any foreign power meddle in the Civil War (Sandy and Molloy, p. 29). These efforts ultimately proved useful, evolving even further throughout the war to ensure American independence.

Another threat from the European nations was the prospect of continued colonization. Due to the disorder brought by the South’s secession and the armies’ preoccupation with each other, many nations began claiming American land, putting pressure on both sides of the conflict. Many public debates were centered around the inefficiencies and instabilities of the American government, predicting further dissolution and lamenting the lack of a monarch on the American throne. The Confederacy feared the European invasion as much as the Union did, so the Southern diplomats continually asserted that the root cause of their secession was a strong desire to govern themselves and not the abolitionist intent of the Union (Sandy and Molloy, p. 26). Such proclamations might be the basis of the argument that states’ rights were a more prevalent cause of the Civil War than slavery. However, that was nothing more than a narrative to stave off European conquest.

Despite all the scholarly debate, the evidence points to slavery being the primary reason for the war. Numerous Confederate politicians and diplomats appeal to the biblical order that places the white above the black, and the slave trade formed the Southern economic landscape, which was a significant driver of political decisions. There were contradicting viewpoints, but they can either be attributed to a growing threat of foreign invasion or traced to the states’ slave ownership rights. Overall, it can be safely said that the degree to which slavery was the leading cause of the Civil War is exceptionally high.

9 Events That Led to the Civil War

By: Patrick J. Kiger

Published: January 17, 2023

Gettysburg Battlefield National Park, Gettysburg, Pennsylvania.

After the American Revolution , a divide between the North and South began to widen. Industrialized northern states gradually passed laws freeing enslaved people, while southern states became increasingly committed to slavery. Many southerners came to view slavery as a linchpin of their agricultural economy , and as a justifiable social and political institution.

Throughout the first half of the 1800s, the nation struggled to manage the clash between these two incompatible viewpoints, working out deals such as the Missouri Compromise of 1820 , which sought to balance the number of new free and slave states and drew a line through the nation’s western territories, with freedom to the north and slavery to the south. But in the last decade before war broke out, the conflict gained momentum and intensity. 

“Throughout the 1850s, a series of events increased sectionalism, emboldened southern secessionists, and deepened northern resolve to defend the Union and end slavery,” explains Jason Phillips , the Eberly Family Professor of Civil War Studies at West Virginia University, and author of the 2018 book Looming Civil War: How Nineteenth Century Americans Imagined the Future. “Many of these crises revolved around politics, but economic, social and cultural factors also contributed to the war’s origins.”

Here are nine events from the 1850s to the early 1860s that historians view as critical in the march toward the American Civil War .

The Compromise of 1850

In the wake of the Mexican War , tensions developed between the North and South over whether the western land gained by the U.S. should become free or slave territory. Things came to a head when California sought approval to enter the Union as a free state in 1849, which would have upset the balance struck by the Missouri Compromise several decades before. Senator Henry Clay, a Whig from Kentucky, proposed a package of legislation to resolve the disputes, but the Senate—after seven months of discussions—rejected his proposal.

Senator Stephen A. Douglas, a Democrat from Illinois, came up with an alternative proposal that admitted California, established Utah and New Mexico as territories that could decide for themselves whether to permit slavery, defined boundaries for the state of Texas, abolished the slave trade in the District of Columbia, and obligated the entire country to cooperate in the capture and return of escaped slaves. But the deal only postponed the conflict.

“They didn’t really compromise,” says Michael Green , an Associate Professor of History at the University of Nevada, Las Vegas and author of several books on the Civil War era, including Politics and America in Crisis: The Coming of the Civil War and Lincoln and the Election of 1860 . “They just agreed to disagree.”

The Fugitive Slave Act

An existing federal law, enacted by Congress in 1793, allowed local governments to seize and return escaped slaves to their owners, and imposed penalties upon anyone who aided their flight. But the new version included in the Compromise of 1850 went much further, by compelling citizens to assist in capturing escapees, denying the captives the right to a jury trial, and increasing the penalty for anyone aiding their escape. It also put cases in the hands of federal commissioners who got $10 if a fugitive was returned, but only $5 if an alleged slave was determined to be a free Black.

Northern abolitionists rebelled against the law. After 50,000 anti-slavery protesters filled the streets of Boston to protest the arrest of a Black man named Anthony Burns in 1854, President Franklin Pierce sent federal troops to maintain order and provided a Navy ship to return Burns back to Virginia.

“Northerners who had questioned slavery said, ‘We told you so,’ and those who hadn’t thought to themselves, ‘This is going too far,’” says Green. “It’s a radicalizing moment.” As a result, Massachusetts and other free states began passing “personal liberty” laws, which made it difficult and costly for enslavers to prove their cases in court.

'Uncle Tom's Cabin' Is Published

Harriet Beecher Stowe, 1811-1896.

In 1851, author Harriet Beecher Stowe , who was still grieving the loss of her 18-month-old son Samuel to cholera two years earlier, wrote to the publisher of a Washington, D.C.-based abolitionist newspaper, National Era , and offered to write a fictional serial about the cruelty of slavery. Stowe later explained that losing her child helped her to understand “what a poor slave mother may feel when her child is ripped away from her,” according to Stowe biographer Katie Griffiths .

Stowe’s story, published in 41 installments, boosted the paper’s circulation, and a Boston publisher decided to release it as a two-volume novel. Uncle Tom’s Cabin: Or, Life Among the Lowly sold 300,000 copies in its first year, and the vociferous public debate about the book exacerbated the differences between the North and South. Northerners were shocked by the brutal depiction of slavery, which Stowe had synthesized from published autobiographies of slaves and stories she had heard from friends and fugitive Blacks. In turn, “Southerners react noisily to it,” Green explains. “They’re saying, ‘This is terrible. You’re attacking us. You’re all against us.’” When Stowe visited the White House in 1862, President Lincoln asked, “So this is the little lady who made this big war?”

The Kansas-Nebraska Act

In 1854, Senator Douglas, the author of the Compromise of 1850, introduced another piece of legislation “to organize the Territory of Nebraska,” an area that covered not just that present-day state but also Kansas, as well as Montana and the Dakotas, according to the U.S. Senate’s history of the law. Douglas was promoting a transcontinental railroad that would pass through Chicago in his home state. But the envisioned northern route had to pass through the Nebraska territory, a place where slavery was prohibited by the 1820 Missouri Compromise. Rivals, including slave owners, wanted a southern route.

To get what he wanted, Douglas offered a compromise, which would allow settlers in those territories to decide whether to legalize slavery. Massachusetts Senator  Charles Sumner , an opponent of slavery, attacked the proposal for creating “a dreary region of despotism.” Nevertheless it was passed by Congress, with cataclysmic results.

“It re-opened that land to the expansion of slavery, and destroyed a long-established political compromise on the issue of slavery in the West,” Phillips says. Pro-slavery and antislavery activists surged into the territories in an effort to sway the vote, and clashed violently in a conflict that became known as “Bleeding Kansas,” which foreshadowed the Civil War.

The Pottawatomie Massacre

A portrait of John Brown (May 9, 1800-December 2, 1859). Brown was an American abolitionist who advocated the use of armed insurrection to overthrow the institution of slavery in the United States.

One of those who went to Kansas was a radical abolitionist and religious zealot named John Brown , who had worked as a conductor on the Underground Railroad and founded an organization that helped slaves escape to Canada. Brown moved to Kansas Territory, where in May 1856, he was angered by the destruction of a newspaper office and other property in Lawrence, Kansas by pro-slavery forces. Brown decided retaliation was in order.

At a spot near a crossing on Pottawatomie Creek in Franklin, Kansas, Brown, four of his sons and several others lured five proslavery men out of their houses with a promise that they would not be harmed, and then slashed and stabbed them with a saber and shot them in the head, according to a contemporary account of the attack. Brown’s brutality was denounced by Southern newspapers and by some Northern ones as well, and it “aroused emotions and distrust on both sides,” as an article from the Kansas Historical Society notes. The fighting in Kansas continued for another two years.

The Dred Scott Decision

Dred Scott.

Dred Scott , an enslaved man, was born in Virginia and later lived in Alabama and Missouri. In 1831, his original enslaver died, and he was purchased by a U.S. Army surgeon named John Emerson. Emerson took him to the free state of Illinois and also Wisconsin, a territory where slavery was illegal due to the Missouri Compromise. During that time, Scott married and he and his wife had four children. In 1843, Emerson died, and several years after that, Scott and his wife sued Emerson’s widow in federal court for their freedom on the grounds that they had lived in free territory.

Scott, who was assisted financially by the family of his original owner, endured years of litigation until the case reached the U.S. Supreme Court. In an 1857 decision written by Chief Justice Roger Taney, the court decided that Scott was not entitled to U.S. citizenship and the protection of law, no matter where he had lived. In the court’s view, the Constitution’s framers had not intended for Black people to be free, but instead viewed them as property, with “no rights which the white man was bound to respect.” The ruling made further political compromise too difficult.

John Brown's Raid on Harper's Ferry

Illustration of abolitionist John Brown leading a raid on Confederate arsenal at Harper's Ferry, Virginia, 1859.

Brown dreamed of carrying out an even bigger attack, one that would ignite a mass uprising of Southern enslaved people. On a night in October 1859, he and a band of 22 men launched a raid on Harpers Ferry , a town in what is now West Virginia, and captured some prominent local citizens and seized the federal arsenal there. His small force soon was counterattacked by local militia, forcing him to seek refuge. The following afternoon, U.S. Marines under the command of then-Col. Robert E. Lee arrived and stormed the arsenal, killing many of Brown’s men and capturing him. Brown was tried and charged with treason, murder and slave insurrection, and sentenced to death. He was hanged in December 1859. While the attack failed to trigger the widespread revolt he envisioned, it drove the North and South even further apart.

“Northern abolitionists who preferred pacificism praised Brown as a martyr to the cause of freedom and even helped to finance his attack,” Phillips explains. “Southerners expected more acts of terrorism and prepared by bolstering their militias.” In many respects, Brown’s raid could be viewed as the first battle of the Civil War, he says.

The Election of 1860

Presidential candidate Abraham Lincoln debating his opponent Steven Douglas in front of a crowd, circa 1858.

Abraham Lincoln , a self-taught lawyer who had served a single term in Congress, emerged in the mid-1850s as an articulate and persuasive critic of slavery, and achieved national prominence with a series of debates against Senator Stephen Douglas in an unsuccessful campaign for Douglas’s seat. When the Republican Party held a convention to nominate a presidential candidate, the chosen location of Chicago gave Lincoln a home-court advantage over more experienced politicians such as Senator William H. Seward of New York.

“When they set up the convention floor, they put Illinois in a spot where they could get to the other delegations that were less committed,” Green says. “The New York delegation, which was supporting Seward, was put in a corner where they couldn’t get out.” That made it difficult for them to negotiate and persuade others to support their candidate. In the general election, Lincoln caught more lucky breaks. After the Democrats were unable to decide upon a candidate, southern Democrats nominated John C. Breckenridge of Kentucky, while northerners nominated Douglas. Breckenridge and Constitutional Party Candidate John Bell split the South, while Lincoln swept the northeastern and midwestern states except for Missouri (which went to Douglas), as well as Oregon and California to win the presidency despite getting just 40 percent of the vote. “For the first time, the Electoral College worked against the South,” Green explains.

The election of the first U.S. president who was a vocal opponent of slavery came as a shock to Southerners. “Now, there is going to be someone in the White House who is not going to do what the South says it wants done, reflexively,” Green explains. “Their feeling is, no matter what Lincoln says about protecting our rights, he’s not going to do that. We don’t trust him. He’s been elected by people who are out to get us.”

Less than six weeks after the election, the first secession convention met in Charleston South Carolina. About 60 percent of the 169 delegates were slave owners, and they voted unanimously to leave the Union . Local residents celebrated with bonfires, parades and the ringing of church bells. Five more states—Mississippi, Florida, Alabama, Georgia and Louisiana—soon followed. Representatives from those six states met in February 1861 to establish a unified government, which they called the Confederate States of America . Jefferson Davis of Mississippi was elected as Confederate President. Texas joined in March. 

After Confederate forces attacked Fort Sumter in April and Lincoln called for federal forces to retake it, four more states—Virginia, Arkansas, North Carolina and Tennessee—left the union and joined the Confederacy as well.

Though the Confederacy’s leaders didn’t realize it, they actually were hastening the end of what they sought to protect. “Had they stayed, slavery as an institution almost certainly would have survived much longer,” Green says.

Instead, a four-year, bloody war devastated much of the South, took the lives of more than 650,000 from both sides, and led to the emancipation of more than 3.9 million enslaved Black Americans, in addition to changing the nation in numerous other ways.

Abraham Lincoln: inauguration

Key Facts of the American Civil War

Abraham Lincoln

A Brief Overview of the American Civil War

This painting portrays Union soldiers waving the American flag, high above the violent battle going on beneath.

The Civil War is the central event in America's historical consciousness. While the Revolution of 1776-1783 created the United States, the Civil War of 1861-1865 determined what kind of nation it would be. The war resolved two fundamental questions left unresolved by the revolution: whether the United States was to be a dissolvable confederation of sovereign states or an indivisible nation with a sovereign national government; and whether this nation, born of a declaration that all men were created with an equal right to liberty, would continue to exist as the largest slaveholding country in the world.

Northern victory in the war preserved the United States as one nation and ended the institution of slavery that had divided the country from its beginning. But these achievements came at the cost of 625,000 lives--nearly as many American soldiers as died in all the other wars in which this country has fought combined. The American Civil War was the largest and most destructive conflict in the Western world between the end of the Napoleonic Wars in 1815 and the onset of World War I in 1914.

The Civil War started because of uncompromising differences between the free and slave states over the power of the national government to prohibit slavery in the territories that had not yet become states. When Abraham Lincoln won election in 1860 as the first Republican president on a platform pledging to keep slavery out of the territories, seven slave states in the deep South seceded and formed a new nation, the Confederate States of America. The incoming Lincoln administration and most of the Northern people refused to recognize the legitimacy of secession. They feared that it would discredit democracy and create a fatal precedent that would eventually fragment the no-longer United States into several small, squabbling countries.

The event that triggered war came at Fort Sumter in Charleston Bay on April 12, 1861. Claiming this United States fort as their own, the Confederate army on that day opened fire on the federal garrison and forced it to lower the American flag in surrender. Lincoln called out the militia to suppress this "insurrection." Four more slave states seceded and joined the Confederacy. By the end of 1861 nearly a million armed men confronted each other along a line stretching 1200 miles from Virginia to Missouri. Several battles had already taken place--near Manassas Junction in Virginia, in the mountains of western Virginia where Union victories paved the way for creation of the new state of West Virginia, at Wilson's Creek in Missouri, at Cape Hatteras in North Carolina, and at Port Royal in South Carolina where the Union navy established a base for a blockade to shut off the Confederacy's access to the outside world.

But the real fighting began in 1862. Huge battles like Shiloh in Tennessee, Gaines' Mill , Second Manassas , and Fredericksburg in Virginia, and Antietam in Maryland foreshadowed even bigger campaigns and battles in subsequent years, from Gettysburg in Pennsylvania to Vicksburg on the Mississippi to Chickamauga and Atlanta in Georgia. By 1864 the original Northern goal of a limited war to restore the Union had given way to a new strategy of "total war" to destroy the Old South and its basic institution of slavery and to give the restored Union a "new birth of freedom," as President Lincoln put it in his address at Gettysburg to dedicate a cemetery for Union soldiers killed in the battle there.

For three long years, from 1862 to 1865, Robert E. Lee's Army of Northern Virginia staved off invasions and attacks by the Union Army of the Potomac commanded by a series of ineffective generals until Ulysses S. Grant came to Virginia from the Western theater to become general in chief of all Union armies in 1864. After bloody battles at places with names like The Wilderness , Spotsylvania , Cold Harbor , and Petersburg , Grant finally brought Lee to bay at Appomattox in April 1865. In the meantime Union armies and river fleets in the theater of war comprising the slave states west of the Appalachian Mountain chain won a long series of victories over Confederate armies commanded by hapless or unlucky Confederate generals. In 1864-1865 General William Tecumseh Sherman led his army deep into the Confederate heartland of Georgia and South Carolina, destroying their economic infrastructure while General George Thomas virtually destroyed the Confederacy's Army of Tennessee at the battle of Nashville . By the spring of 1865 all the principal Confederate armies surrendered, and when Union cavalry captured the fleeing Confederate President Jefferson Davis in Georgia on May 10, 1865, resistance collapsed and the war ended. The long, painful process of rebuilding a united nation free of slavery began.

Professional historians can be an argumentative lot, but by the dawn of the twenty-first century, a broad consensus regarding Civil War causation clearly reigned. Few mainstream scholars would deny that Abraham Lincoln got it right in his second inaugural address—that slavery was “somehow” the cause of the war. Public statements by preeminent historians reaffirmed that slavery's centrality had been proven beyond a reasonable doubt. Writing for the popular Civil War magazine North and South in November 2000, James M. McPherson pointed out that during the war, “few people in either North or South would have dissented” from Lincoln's slavery-oriented account of the war's origins. In ten remarkably efficient pages, McPherson dismantled arguments that the war was fought over tariffs, states' rights, or the abstract principle of secession. That same year, Charles Joyner penned a report on Civil War causation for release at a Columbia, South Carolina, press conference at the peak of the Palmetto State's Confederate flag debate. Endorsed by dozens of scholars and later published in Callaloo, it concluded that the “historical record … clearly shows that the cause for which the South seceded and fought a devastating war was slavery.” 1

Despite the impulse to close ranks amid the culture wars, however, professional historians have not abandoned the debate over Civil War causation. Rather, they have rightly concluded that there is not much of a consensus on the topic after all. Elizabeth Varon remarks that although “scholars can agree that slavery, more than any other issue, divided North and South, there is still much to be said about why slavery proved so divisive and why sectional compromise ultimately proved elusive.” And as Edward Ayers observes: “slavery and freedom remain the keys to understanding the war, but they are the place to begin our questions, not to end them.” 2 The continuing flood of scholarship on the sectional conflict suggests that many other historians agree. Recent work on the topic reveals two widely acknowledged truths: that slavery was at the heart of the sectional conflict and that there is more to learn about precisely what this means, not least because slavery was always a multifaceted issue.

This essay analyzes the extensive literature on Civil War causation published since 2000, a body of work that has not been analyzed at length. This survey cannot be comprehensive but seeks instead to clarify current debates in a field long defined by distinct interpretive schools—such as those of the progressives, revisionists, and modernization theorists—whose boundaries are now blurrier. To be sure, echoes still reverberate of the venerable arguments between historians who emphasize abstract economic, social, or political forces and those who stress human agency. The classic interpretive schools still command allegiance, with fundamentalists who accentuate concrete sectional differences dueling against revisionists, for whom contingency, chance, and irrationality are paramount. But recent students of Civil War causation have not merely plowed familiar furrows. They have broken fresh ground, challenged long-standing assumptions, and provided new perspectives on old debates. This essay explores three key issues that vein the recent scholarship: the geographic and temporal parameters of the sectional conflict, the relationship between sectionalism and nationalism, and the relative significance of race and class in sectional politics. All three problems stimulated important research long before 2000, but recent work has taken them in new directions. These themes are particularly helpful for navigating the recent scholarship, and by using them to organize and evaluate the latest literature, this essay underscores fruitful avenues for future study of a subject that remains central in American historiography. 3

Historians of the sectional conflict, like their colleagues in other fields, have consciously expanded the geographic and chronological confines of their research. Crossing the borders of the nation-state and reaching back toward the American Revolution, many recent studies of the war's origins situate the clash over slavery within a broad spatial and temporal context. The ramifications of this work will not be entirely clear until an enterprising scholar incorporates those studies into a new synthesis, but this essay will offer a preliminary evaluation.

Scholarship following the transnational turn in American history has silenced lingering doubts that nineteenth-century Americans of all regions, classes, and colors were deeply influenced by people, ideas, and events from abroad. Historians have long known that the causes of the Civil War cannot be understood outside the context of international affairs, particularly the Mexican-American War (1846–1848). Three of the most influential narrative histories of the Civil War era open either on Mexican soil (those written by Allan Nevins and James McPherson) or with the transnational journey from Mexico City to Washington of the 1848 Treaty of Guadalupe Hidalgo (David M. Potter's The Impending Crisis ). The domestic political influence of the annexation of Texas, Caribbean filibustering, and the Ostend Manifesto, a widely publicized message written to President Franklin Pierce in 1854 that called for the acquisition of Cuba, are similarly well established. 4

Recent studies by Edward Bartlett Rugemer and Matthew J. Clavin, among others, build on that foundation to show that the international dimensions of the sectional conflict transcended the bitterly contested question of territorial expansion. Rugemer, for instance, demonstrates that Caribbean emancipation informed U.S. debates over slavery from the Haitian Revolution (1791–1804) through Reconstruction. Situating sectional politics within the Atlantic history of slavery and abolition, he illustrates how arguments for and against U.S. slavery drew from competing interpretations of emancipation in the British West Indies. Britain's “mighty experiment” thus provided “useable history for an increasingly divided nation.” Proslavery ideologues learned that abolitionism sparked insurrection, that Africans and their descendants would become idlers or murderers or both if released from bondage, and that British radicals sought to undermine the peculiar institution wherever it persisted. To slavery's foes, the same history revealed that antislavery activism worked, that emancipation could be peaceful and profitable, and that servitude, not skin tone, degraded enslaved laborers. Clavin's study of American memory of Toussaint L'Ouverture indicates that the Haitian Revolution cast an equally long shadow over antebellum history. Construed as a catastrophic race war, the revolution haunted slaveholders with the prospect of an alliance between ostensibly savage slaves and fanatical whites. Understood as a hopeful story of the downtrodden overthrowing their oppressors, however, Haitian history furnished abolitionists, white and black, with an inspiring example of heroic self-liberation by the enslaved. By the 1850s it also furnished abolitionists, many of whom were frustrated by the abysmally slow progress of emancipation in the United States, with a precedent for swift, violent revolution and the vindication of black masculinity. The Haitian Revolution thus provided “resonant, polarizing, and ultimately subversive symbols” for antislavery and proslavery partisans alike and helped “provoke a violent confrontation and determine the fate of slavery in the United States.” 5

These findings will surprise few students of Civil War causation, but they demonstrate that the international aspects of the sectional conflict did not begin and end with Manifest Destiny. They also encourage Atlantic historians to pay more attention to the nineteenth century, particularly to the period after British emancipation. Rugemer and Clavin point out that deep connections among Atlantic rim societies persisted far into the nineteenth century and that, like other struggles over New World slavery, the American Civil War is an Atlantic story. One of their most stimulating contributions may therefore be to encourage Atlantic historians to widen their temporal perspectives to include the middle third of the nineteenth century. By foregrounding the hotly contested public memory of the Haitian Revolution, Rugemer and Clavin push the story of American sectionalism back into the late eighteenth and early nineteenth centuries, suggesting that crossing geographic boundaries can go hand in hand with stretching the temporal limits of sectionalism. 6

The internationalizing impulse has also nurtured economic interpretations of the sectional struggle. Brian Schoen, Peter Onuf, and Nicholas Onuf situate antebellum politics within the context of global trade, reinvigorating economic analysis of sectionalism without summoning the ghosts of Charles Beard and Mary Beard. Readers may balk at their emphasis on tariff debates, but these histories are plainly not Confederate apologia. As Schoen points out, chattel slavery expanded in the American South, even as it withered throughout most of the Atlantic world, because southern masters embraced the nineteenth century's most important crop: cotton. Like the oil titans of a later age, southern cotton planters reveled in the economic indispensability of their product. Schoen adopts a cotton-centered perspective from which to examine southern political economy, from the earliest cotton boom to the secession crisis. “Broad regional faith in cotton's global power,” he argues, “both informed secessionists' actions and provided them an indispensable tool for mobilizing otherwise reluctant confederates.” Planters' commitment to the production and overseas sale of cotton shaped southern politics and business practices. It impelled westward expansion, informed planters' jealous defense of slavery, and wedded them to free trade. An arrogant faith in their commanding economic position gave planters the impetus and the confidence to secede when northern Republicans threatened to block the expansion of slavery and increase the tariff. The Onufs reveal a similar dynamic at work in their complementary study, Nations, Markets, and War. Like Schoen, they portray slaveholders as forward-looking businessmen who espoused free-trade liberalism in defense of their economic interests. Entangled in political competition with Yankee protectionists throughout the early national and antebellum years, slaveholders seceded when it became clear that their vision for the nation's political economy—most importantly its trade policy—could no longer prevail. 7

These authors examine Civil War causation within a global context, though in a way more reminiscent of traditional economic history than similar to other recent transnational scholarship. But perhaps the most significant contribution made by these authors lies beyond internationalizing American history. After all, most historians of the Old South have recognized that the region's economic and political power depended on the Atlantic cotton trade, and scholars of the Confederacy demonstrated long ago that overconfidence in cotton's international leverage led southern elites to pursue a disastrous foreign policy. What these recent studies reveal is that cotton-centered diplomatic and domestic politics long predated southern independence and had roots in the late eighteenth century, when slaveholders' decision to enlarge King Cotton's domain set them on a turbulent political course that led to Appomattox. The Onufs and Schoen, then, like Rugemer and Clavin, expand not only the geographic parameters of the sectional conflict but also its temporal boundaries. 8

These four important histories reinforce recent work that emphasizes the eruption of the sectional conflict at least a generation before the 1820 Missouri Compromise. If the conflict over Missouri was a “firebell in the night,” as Thomas Jefferson called it, it was a rather tardy alarm. This scholarship mirrors a propensity among political historians—most notably scholars of the civil rights movement—to write “long histories.” Like their colleagues who dispute the Montgomery-to-Memphis narrative of the civil rights era, political historians of the early republic have questioned conventional periodization by showing that sectionalism did not spring fully grown from the head of James Tallmadge, the New York congressman whose February 1819 proposal to bar the further extension of slavery into Missouri unleashed the political storm that was calmed, for the moment, by the Missouri Compromise. Matthew Mason, for instance, maintains that “there never was a time between the Revolution and the Civil War in which slavery went unchallenged.” Mason shows that political partisans battered their rivals with the club of slavery, with New England Federalists proving especially adept at denouncing their Jeffersonian opponents as minions of southern slaveholders. In a series of encounters, from the closure of the Atlantic slave trade in 1807 to the opening (fire)bell of the Missouri crisis, slavery remained a central question in American politics. Even the outbreak of war in 1812 failed to suppress the issue. 9

A complementary study by John Craig Hammond confirms that slavery roiled American politics from the late eighteenth century on and that its westward expansion proved especially divisive years before the Missouri fracas. As America's weak national government continued to bring more western acreage under its nominal control, it had to accede to local preferences regarding slavery. Much of the fierce conflict over slavery therefore occurred at the territorial and state levels. Hammond astutely juxtaposes the histories of slave states such as Louisiana and Missouri alongside those of Ohio and Indiana, where proslavery policies were defeated. In every case, local politics proved decisive. Neither the rise nor the extent of the cotton kingdom was a foregone conclusion, and the quarrel over its expansion profoundly influenced territorial and state politics north and south of the Ohio River. Bringing the growing scholarship on both early republic slavery and proslavery ideology into conversation with political history, Hammond demonstrates that the bitterness of the Missouri debate stemmed from that dispute's contentious prehistory, not from its novelty. Just as social, economic, and intellectual historians have traced the “long history” of the antebellum South back to its once relatively neglected early national origins, political historians have uncovered the deep roots of political discord over slavery's expansion. 10

Scholars have applied the “long history” principle to other aspects of Civil War causation as well. In his study of the slave power thesis, Leonard L. Richards finds that northern anxieties about slaveholders' inordinate political influence germinated during the 1787 Constitutional Convention. Jan Lewis's argument that the concessions made to southern delegates at the convention emboldened them to demand special protection for slavery suggests that those apprehensions were sensible. David L. Lightner demonstrates that northern demands for a congressional ban on the domestic slave trade, designed to strike a powerful and, thanks to the interstate commerce clause, constitutional blow against slavery extension emerged during the first decade of the nineteenth century and informed antislavery strategy for the next fifty years. Richard S. Newman emphasizes that abolitionist politics long predated William Lloyd Garrison's founding of the Liberator in 1831. Like William W. Freehling, who followed the “road to disunion” back to the American Revolution, Newman commences his study of American abolitionism with the establishment of the Pennsylvania Abolition Society in 1775. Most recently, Christopher Childers has invited historians to explore the early history of the doctrine of popular sovereignty. 11

Skeptics might ask where the logic of these studies will lead. Why not push the origins of sectional strife even further back into colonial history? Why not begin, as did a recent overview of Civil War causation, with the initial arrival of African slaves in Virginia in 1619? This critique has a point—hopefully we will never read an article called “Christopher Columbus and the Coming of the American Civil War”—but two virtues of recent work on the long sectional conflict merit emphasis. First, its extended view mirrors the very long, if chronically selective, memories of late antebellum partisans. By the 1850s few sectional provocateurs failed to trace northern belligerence toward the South, and vice versa, back to the eighteenth century. Massachusetts Republican John B. Alley reminded Congress in April 1860 that slavery had been “a disturbing element in our national politics ever since the organization of the Government.” “In fact,” Alley recalled, “political differences were occasioned by it, and sectional prejudices grew out of it, at a period long anterior to the formation of the Federal compact.” Eight tumultuous months later, U.S. senator Robert Toombs recounted to the Georgia legislature a litany of northern aggressions and insisted that protectionism and abolitionism had tainted Yankee politics from “ the very first Congress .” Tellingly, the study of historical memory, most famously used to analyze remembrance of the Civil War, has moved the study of Civil War causation more firmly into the decades between the nation's founding and the Missouri Compromise. Memories of the Haitian Revolution shaped antebellum expectations for emancipation. Similarly, recollections of southern economic sacrifice during Jefferson's 1807 embargo and the War of 1812 heightened white southerners' outrage over their “exclusion” from conquered Mexican territory more than three decades later. And as Margot Minardi has shown, Massachusetts abolitionists used public memory of the American Revolution to champion emancipation and racial equality. The Missouri-to-Sumter narrative conceals that these distant events haunted the memories of late antebellum Americans. Early national battles over slavery did not make the Civil War inevitable, but in the hands of propagandists they could make the war seem inevitable to many contemporaries. 12

Second, proponents of the long view of Civil War causation have not made a simplistic argument for continuity. Elizabeth Varon's study of the evolution of disunion as a political concept and rhetorical device from 1789 to 1859 demonstrates that long histories need not obscure change over time. Arguing that “sectional tensions deriving from the diverging interests of the free labor North and the slaveholding South” were “as old as the republic itself,” Varon adopts a long perspective on sectional tension. But her nuanced analysis of the diverse and shifting political uses of disunion rhetoric suggests that what historians conveniently call the sectional conflict was in fact a series of overlapping clashes, each with its own dynamics and idiom. Quite literally, the terms of sectional debate remained in flux. The language of disunion came in five varieties—“a prophecy of national ruin, a threat of withdrawal from the federal compact, an accusation of treasonous plotting, a process of sectional alienation, and a program for regional independence”—and the specific meanings of each cannot be interpreted accurately without regard to historical context, for “their uses changed and shifted over time.” To cite just one example, the concept of disunion as a process of increasing alienation between North and South gained credibility during the 1850s as proslavery and antislavery elements clashed, often violently, over the Fugitive Slave Act of 1850 and the extension of slavery into Kansas. Republican senator William Henry Seward's famous “irrepressible conflict” speech of 1858 took this interpretation of disunion, one that had long languished on the radical margins of sectional politics, and thrust it into mainstream discourse. Shifting political circumstances reshaped the terms of political debate from the 1830s, when the view of disunion as an irreversible process flourished only among abolitionists and southern extremists, to the late 1850s, when a leading contender for the presidential nomination of a major party could express it openly. 13

Consistent with Varon's emphasis on the instability of political rhetoric, other recent studies of Civil War causation have spotlighted two well-known and important forks in the road to disunion. Thanks to their fresh perspective on the crisis of 1819–1821, scholars of early national sectionalism have identified the Missouri struggle as the first of these turning points. The battle over slavery in Missouri, Robert Pierce Forbes argues, was “a crack in the master narrative” of American history that fundamentally altered how Americans thought about slavery and the Union. In the South, it nurtured a less crassly self-interested defense of servitude. Simultaneously, it tempted northerners to conceptually separate “the South” from “America,” thereby sectionalizing the moral problem of slavery and conflating northern values and interests with those of the nation. The intensity of the crisis demonstrated that the slavery debate threatened the Union, prompting Jacksonian-era politicians to suppress the topic and stymie sectionalists for a generation. But even as the Missouri controversy impressed moderates with the need for compromise, it fostered “a new clarity in the sectional politics of the United States and moved each section toward greater coherence on the slavery issue” by refining arguments for and against the peculiar institution. The competing ideologies that defined antebellum sectional politics coalesced during the contest over Missouri, now portrayed as a milestone rather than a starter's pistol. 14

A diverse body of scholarship identifies a second period of discontinuity stretching from 1845 to 1850. This literature confirms rather than challenges traditional periodization, for those years have long marked the beginning of the “Civil War era.” This time span has attracted considerable attention because the slavery expansion debate intensified markedly between the annexation of Texas in 1845 and the Compromise of 1850. Not surprisingly, recent work on slavery's contested westward extension continues to present the late 1840s as a key turning point—perhaps a point of no return—in the sectional conflict. As Michael S. Green puts it, by 1848, “something in American political life clearly had snapped. … [T]he genies that [James K.] Polk, [David] Wilmot, and their allies had let out of the bottle would not be put back in.” 15

Scholars not specifically interested in slavery expansion have also identified the late 1840s as a decisive period. In his history of southern race mythology—the notion that white southerners' “Norman” ancestry elevated them over Saxon-descended northerners—Ritchie Devon Watson Jr. identifies these years as a transition period between two theories of sectional difference. White southerners' U.S. nationalism persisted into the 1840s, he argues, and although they recognized cultural differences between the Yankees and themselves, the dissimilarities were not imagined in racial terms. After 1850, however, white southerners increasingly argued for innate differences between the white southern “race” and its ostensibly inferior northern rival. This mythology was a “key element” in the “flowering of southern nationalism before and during the Civil War.” Susan-Mary Grant has shown that northern opinion of the South underwent a simultaneous shift, with the slave power thesis gaining widespread credibility by the late 1840s. The year 1850 marked an economic turning point as well. Marc Egnal posits that around that year, a generation of economic integration between North and South gave way to an emerging “Lake Economy,” which knit the Northwest and Northeast into an economic and political alliance at odds with the South. Taken together, this scholarship reaffirms what historians have long suspected about the sectional conflict: despite sectionalism's oft-recalled roots in the early national period, the late 1840s represents an important period of discontinuity. It is unsurprising that these years climaxed with a secession scare and a makeshift compromise reached not through bona fide give-and-take but rather through the political dexterity of Senator Stephen A. Douglas. 16

That Douglas succeeded where the eminent Henry Clay had failed suggests another late 1840s discontinuity that deserves more scholarly attention. Thirty-six years older than the Little Giant, Clay was already Speaker of the House when Douglas was born in 1813. Douglas's shepherding of Clay's smashed omnibus bill through the Senate in 1850 “marked a changing of the guard from an older generation, whose time already might have passed, to a new generation whose time had yet to come.” This passing of the torch symbolized a broader shift in political personnel. The Thirty-First Congress, which passed the compromise measures of 1850, was a youthful assembly. The average age for representatives was forty-three, only two were older than sixty-two, and more than half were freshmen. The Senate was similarly youthful, particularly its Democratic members, fewer than half of whom had reached age fifty. Moreover, the deaths of John C. Calhoun, Henry Clay, and Daniel Webster between March 1850 and October 1852 signaled to many observers the end of an era. In 1851 members of the University of Virginia's Southern Rights Association reminded their southern peers that “soon the destinies of the South must be entrusted to our keeping. The present occupants of the arena of action must soon pass away, and we be called upon to fill their places. … It becomes therefore our sacred duty to prepare for the contest.” 17

Students of Civil War causation would do well to probe this intergenerational transfer of power. This analysis need not revive the argument, most popular in the 1930s and 1940s, that the “blundering generation” of hot-headed and self-serving politicos who grasped the reins of power around 1850 brought on an unnecessary war. Caricaturing the rising generation as exceptionally inept is not required to profitably contrast the socioeconomic environments, political contexts, and intellectual milieus in which Clay's and Douglas's respective generations matured. These differences, and the generational conflict that they engendered, may have an important bearing on both the origins and the timing of the Civil War. Peter Carmichael's study of Virginia's last antebellum generation explores this subject in detail. Historians have long recognized that disproportionately high numbers of young white southerners supported secession. Carmichael offers a compelling explanation for why this was so, without portraying his subjects as mediocre statesmen or citing the eternal impetuousness of youth. Deftly blending cultural, social, economic, and political history, Carmichael rejects the notion that young Virginia gentlemen who came of age in the late 1850s were immature, impassioned, and reckless. They were, he argues, idealistic and ambitious men who believed deeply in progress but worried that their elders had squandered Virginia's traditional economic and political preeminence. Confronted with their state's apparent degeneration and their own lack of opportunity for advancement, Carmichael's young Virginians endorsed a pair of solutions that put them at odds with their conservative elders: economic diversification and, after John Brown's 1859 raid on Harpers Ferry, southern independence. Whether this generational dynamic extended beyond Virginia remains to be seen. But other recent works, including Stephen Berry's study of young white men in the Old South and Jon Grinspan's essay on youthful Republicans during the 1860 presidential campaign, indicate that similar concerns about progress, decline, and sectional destiny haunted many young minds on the eve of the Civil War. More work in this area is necessary, especially on how members of the new generation remembered the sectional conflict that had been raging since before they were born. Clearly, though, the generation that ascended to national leadership during the 1850s came of age in a very different world than had its predecessor. Further analysis of this shift promises to link the insights of the long sectional conflict approach (particularly regarding public memory) with the emphasis on late 1840s discontinuity that veins recent scholarship on sectionalism. 18

Recent historians have challenged conventional periodization by expanding the chronological scope of the sectional conflict, even as they confirm two key moments of historical discontinuity. This work revises older interpretations of Civil War causation without overturning them. A second trend in the literature, however, is potentially more provocative. A number of powerfully argued studies building on David Potter's classic essay, “The Historian's Use of Nationalism and Vice Versa,” have answered his call for closer scrutiny of the “seemingly manifest difference between the loyalties of a nationalistic North and a sectionalistic South.” Impatient with historians who read separatism into all aspects of prewar southern politics or Unionism into all things northern, Potter admonished scholars not to project Civil War loyalties back into the antebellum period. A more nuanced approach would reveal “that in the North as well as in the South there were deep sectional impulses, and support or nonsupport of the Union was sometimes a matter of sectional tactics rather than of national loyalty.” Recent scholars have accepted Potter's challenge, and their findings contribute to an emerging reinterpretation of the sectional conflict and the timing of secession. 19

Disentangling northern from national interests and values has been difficult thanks in part to the Civil War itself (in which “the North” and “the Union” overlapped, albeit imperfectly) and because of the northern victory and the temptation to classify the Old South as an un-American aberration. But several recent studies have risen to the task. Challenging the notion that the antebellum North must have been nationalistic because of its opposition to slavery and its role in the Civil War, Susan-Mary Grant argues that by the 1850s a stereotyped view of the South and a sense of moral and economic superiority had created a powerful northern sectional identity. Championed by the Republican party, this identity flowered into an exclusionary nationalism in which the South served as a negative reference point for the articulation of ostensibly national values, goals, and identities based on the North's flattering self-image. This sectionalism-cum-nationalism eventually corroded national ties by convincing northerners that the South represented an internal threat to the nation. Although this vision became genuinely national after the war, in the antebellum period it was sectionally specific and bitterly divisive. “It was not the case,” Grant concludes, “that the northern ideology of the antebellum period was American, truly national, and supportive of the Union and the southern ideology was wholly sectional and destructive of the Union.” Matthew Mason makes a related point about early national politics, noting that the original sectionalists were antislavery New England Federalists whose flirtation with secession in 1815 crippled their party. Never simply the repository of authentic American values, the nineteenth-century North developed a sectional identity in opposition to an imagined (though not fictitious) South. Only victory in the Civil War allowed for the reconstruction of the rest of the nation in this image. 20

If victory in the war obscured northern sectionalism, it was the defense of slavery, coupled with defeat, that has distorted our view of American nationalism in the Old South. The United States was founded as a slaveholding nation, and there was unfortunately nothing necessarily un-American about slavery in the early nineteenth century. Slavery existed in tension with, not purely in opposition to, the nation's perennially imperfect political institutions, and its place in the young republic was a hotly contested question with a highly contingent resolution. Moreover, despite their pretensions to being an embattled minority, southern elites long succeeded in harnessing national ideals and federal power to their own interests. Thus, defense of slavery was neither inevitably nor invariably secessionist. This is a key theme of Robert Bonner's expertly crafted history of the rise and fall of proslavery American nationalism. Adopting a long-sectional-conflict perspective, Bonner challenges historians who have “conflate[d] an understandable revulsion at proslavery ideology with a willful disassociation of bondage from prevailing American norms.” He details the efforts of proslavery southerners to integrate slavery into national identity and policy and to harmonize slaveholding with American expansionism, republicanism, constitutionalism, and evangelicalism. Appropriating the quintessentially American sense of national purpose, proslavery nationalists “invited outsiders to consider [slavery's] compatibility with broadly shared notions of American values and visions of a globally redeeming national mission.” This effort ended in defeat, but not because proslavery southerners chronically privileged separatism over nationalism. Rather, it was their failure to bind slavery to American nationalism—signaled by the Republican triumph in 1860—that finally drove slaveholders to secede. Lincoln's victory “effectively ended the prospects for achieving proslavery Americanism within the federal Union,” forcing slavery's champions to pin their hopes to a new nation-state. Confederate nationalism was more a response to the demise of proslavery American nationalism than the cause of its death. 21

Other recent studies of slaveholders' efforts to nationalize their goals and interests complement Bonner's skilled analysis. Matthew J. Karp casts proslavery politicians not as jumpy sectionalists but as confident imperialists who sponsored an ambitious and costly expansion of American naval power to protect slavery against foreign encroachment and to exert national influence overseas. For these slaveholding nationalists, “federal power was not a danger to be feared, but a force to be utilized,” right up to the 1860 election. Similarly, Brian Schoen has explored cotton planters' efforts to ensure that national policy on tariff rates and slavery's territorial status remained favorable to their interests. As cotton prices boomed during the 1850s, planters grew richer and the stakes grew higher, especially as their national political power waned with the ascension of the overtly sectional Republican party. The simultaneous increase in planters' economic might and decline in their political dominance made for an explosive mixture that shattered the bonds of the Union. Still, one must not focus solely on cases in which proslavery nationalism was thwarted, for its successes convinced many northerners of the veracity of the slave power thesis, helping further corrode the Union. James L. Huston shows that both southern efforts to nationalize property rights in slaves and the prospect of slavery becoming a national institution—in the sense that a fully integrated national market could bring slave and free labor into competition—fueled northern sectionalism and promoted the rise of the Republican party. Proslavery nationalism and its policy implications thus emboldened the political party whose victory in 1860 convinced proslavery southerners that their goals could not be realized within the Union. 22

As the standard-bearers of northern and southern interests battled for national power, both sides emphasized that their respective ideologies were consistent with the nation's most cherished principles. Shearer Davis Bowman has argued that “northern and southern partisans of white sectionalism tended to see their respective sections as engaged in the high-minded defense of vested interests, outraged rights and liberties, and imperiled honor, all embedded in a society and way of life they deemed authentically American.” In a sense, both sides were right. Recent scholarship in such varied fields as intellectual, religious, political, and literary history suggests that although often incompatible, the values and ideals of the contending sections flowed from a common source. Work by Margaret Abruzzo on proslavery and antislavery humanitarianism, John Patrick Daly and Mark A. Noll on evangelical Protestantism, Sean Wilentz on political democracy, and Diane N. Capitani on domestic sentimental fiction suggests that the highly politicized differences between northern and southern ideologies masked those ideologies' common intellectual roots. Some scholars have argued for more fundamental difference, maintaining that southern thinkers roundly rejected democracy and liberal capitalism, while others have gone too far in the other direction in presenting northern and southern whites as equally committed to liberalism. But the dominant thrust of recent work on sectional ideologies suggests that they represented two hostile sides of a single coin minted at the nation's founding. Since a coin flip cannot end in a tie, both sides struggled for control of the national government to put their incompatible ideals into practice. The nationalization of northern ideals was a hotly contested outcome, made possible only by armed conflict. Conversely, the sectionalization of white southern ideals was not inevitable. Proponents of both sections drew on nationalism and sectionalism alike, embracing the former when they felt powerful and the latter when they felt weak. “As long as the Government is on our side,” proslavery Democrat and future South Carolina governor Francis W. Pickens wrote in 1857, “I am for sustaining it and using its power for our benefit. … [if] our opponents reverse the present state of things then I am for war .” 23

Together, recent studies of northern sectionalism and southern nationalism make a compelling case for why the Civil War broke out when it did. If the South was always a separatist minority and if the North always defended the American way, secession might well have come long before 1861. It is more helpful to view the sectional conflict as one between equally authentic (not morally equivalent) strands of American nationalism grappling for the power to govern the entire country according to sectionally specific values. Southern slaveholders ruled what was in many ways the weaker section, but constitutional privileges such as the infamous three-fifths clause, along with other advantageous provisions such as the rule requiring a two-thirds majority in the nominations of Democratic presidential candidates, allowed them to remain dominant prior to 1860, until their successes aroused a sense of northern sectionalism robust enough to lift the Republican party into power. Almost overnight, the proslavery nationalist project collapsed. Only then did decisive numbers of southern whites countenance disunion, a drastic measure whose use had long been resisted within the South. The Civil War erupted when northern sectionalism grew powerful enough to undermine southern nationalism. 24

In the model of Civil War causation sketched above, northern voters who joined the Republicans fretted over the fate of liberty in a slaveholding republic. But whose liberty was at stake? Recent scholarship powerfully demonstrates that for moderate opponents of slavery the most damnable aspect of the institution was not what it did to slaves but what it allowed slaveholders to do to northern whites. Popular antislavery grew from trepidation about the power of the slaveholding class and its threat to republican liberty, not from uproar against proslavery racism and racial oppression. And since this concern fueled the Republican party's rapid growth and 1860 presidential triumph, white northerners' indignant response to slaveholders' clout contributed significantly to the coming of the war by providing secessionists with a pretext for disunion. According to this interpretation of northern politics, slavery remains at the root of the sectional conflict even though racial egalitarianism did not inspire the most popular brands of antislavery politics and even though many of the debates over slavery, as Eric Foner has pointed out, “were only marginally related to race.” At the same time, recent scholarship on southern politics foregrounds slave agency and persuasively demonstrates that conflict between masters and slaves directly affected national affairs. If the fate of the enslaved did not preoccupy most northern whites, the same cannot be said of their southern counterparts, whose politics are intelligible only in the context of slave resistance. In sum, recent work confirms the centrality of slavery in the coming of the war in a very specific and nuanced way, showing that the actions and contested status of enslaved people influenced southern politics directly and northern politics more obliquely. This work reveals an asymmetry in the politics of slavery: in the South it revolved around maintaining control over slaves in the name of white supremacy and planters' interests, while in the North it centered on the problem of the slaveholding class. 25

Moral indignation at racial prejudice in the twentieth century does not necessarily provide the key to an understanding of the dispute between the sections in the nineteenth century. While some abolitionists were indignant at the slave system and what it did to black men, many more northerners became antisouthern and antislavery because of what the slave system did or threatened to do to them. A failure to recognize this can easily lead us into a blind alley of oversimplification, and to view the events of a hundred years ago as a morality play with heroes and villains rather than a plausible presentation of a human dilemma.

Many twenty-first century scholars have taken this point to heart while implicitly challenging Gara's stark contrast between moral and self-interested antislavery. They stress the primary importance of white liberty in popular antislavery critiques but show that slavery's “moderate” opponents were no less morally outraged than their “radical” counterparts. Slavery could be condemned on moral grounds for a wide variety of reasons, some of which had much to do with enslaved people and some of which—whether they stressed the degeneracy of southern society, the undemocratic influence of slaveholders' political clout, or the threat that proslavery zealots posed to civil liberties—did not. Thus, recent scholars have made Gara's “crucial distinction” while underlining the moral dimensions of ostensibly moderate, conservative, or racist antislavery arguments. Popular antislavery strove to protect democratic politics from the machinations of a legally privileged and economically potent ruling class. Slaveholders' inordinate political power was itself a moral problem. These findings may prompt historians to reconsider the relative emphasis placed on class and race in the origins and meanings of the Civil War, particularly regarding the political behavior of the nonabolitionist northern majority. 27

Numerous recent studies emphasize that perceived threats to white freedom pushed northerners to oppose the slave power, support the Republican party, and prosecute the Civil War on behalf of liberty and the Union. Nicole Etcheson's study of the violent struggle between proslavery and antislavery forces over Kansas during the mid-1850s contends that the key issue at stake was freedom for white settlers. During the Civil War many Kansans who had fought for the admission of their state under an antislavery constitution applauded emancipation, but Etcheson persuasively argues that “Bleeding Kansas began as a struggle to secure the political liberties of whites.” Racist pioneers from both sections battled to ensure that the plains would remain a haven for white freedom, disagreeing primarily over slavery's compatibility with that goal. Similarly, Matthew Mason shows that antislavery politics in the early national period, spearheaded by Federalists, thrived only when northern voters recognized “how slavery impinged on their rights and interests.” Russell McClintock's analysis of the 1860 election and northerners' reaction to secession and the bombardment of Fort Sumter indicates that anxiety over slaveholders' power encouraged a decisive, violent northern response. As the antislavery position edged closer to the mainstream of northern politics, critiques of slavery grounded in sympathy for enslaved people faded as less philanthropic assaults on the institution proliferated. Carol Lasser's study of the shifting emphasis of antislavery rhetoric demonstrates that between the 1830s and the 1850s, “self-interest replaced sin as a basis for antislavery organizing,” as antislavery appeals increasingly “stressed the self-interest of northern farmers and workers—mainly white and mainly male.” Ultimately, popular antislavery cast “free white men, rather than enslaved African American women,” as “the victims of ‘the peculiar institution.’” 28

Even histories of fugitive slave cases underscore the preeminence of white liberty as the activating concern for many northerners. As the historian Earl M. Maltz has pointed out, the fugitive slave issue was never isolated from other political controversies. Thanks to the Kansas-Nebraska Act, which seemed to prove the existence of a southern plot to spread slavery onto previously free western soil, fugitive slave cases during and after 1854 aroused increased hostility among white northerners who suspected that slaveholders threatened the liberties of all Americans. Those fears intensified throughout the 1850s in response to cases in which free northerners stood trial for violation of the Fugitive Slave Act. In two of the three cases explored by Steven Lubet the defendants were not runaway slaves but predominantly white northerners accused of abetting fugitives from slavery. The Fugitive Slave Act's criminalization of noncompliance with slave catchers proved especially odious. “For all of its blatant unfairness,” Lubet argues, “the Act might have been considered tolerable in the North—at least among non-abolitionists—if it had been directed only at blacks.” It was not, of course, and some of the act's most celebrated cases placed white northerners in legal jeopardy for crossing swords with the slave power. Two recent studies of the Joshua Glover case reinforce this point. Formerly a slave in St. Louis, Glover escaped to Wisconsin and, with the help of sympathetic white residents, from there to Canada in 1854. But the dramatic confrontation between free-state citizens and the slaveholder-dominated federal government only began with Glover's successful flight, since the political reverberations of the case echoed for many years after Glover reached Canadian soil. Debates over the rights and duties of citizens, over the boundaries of state and federal sovereignty, and over the constitutionality of the Fugitive Slave Act hinged on the prosecution of the primarily white Wisconsinites who aided Glover's escape. None gained more notoriety than Sherman Booth, the Milwaukee newspaper editor whose case bounced between state and federal courts from 1854 to 1859, and whose attorney, Byron Paine, capitalized on his own resulting popularity to win a seat on the Wisconsin Supreme Court. Long after attention left Glover, who was undoubtedly relieved to be out of the public eye, conflicts over northern state rights and individual rights highlighted the threat to white liberty posed by the slave power and its federal agents. 29

Of course, the white northerners prosecuted under proslavery law would have remained in obscurity if not for the daring escapes made by enslaved people. As Stanley Harrold has shown, runaway slaves sparked dozens of bloody skirmishes in the antebellum borderland between slavery and freedom. To stress the importance of conflicts over white liberty in the coming of the Civil War is not to ignore the political impact of slave resistance. Quite the reverse: recent studies of Civil War causation have deftly explored the relationship between slave agency and sectional antagonism, revealing that slave resistance provoked conflict between whites, even in situations where racial justice was not the main point of contention. Northern sectionalism was a reaction against proslavery belligerence, which was fueled by internal conflicts in the South. Narratives of Civil War causation that focus on white northerners' fears for their liberties depend on slave agency, for the aggressiveness of the slave power was, essentially, a response to the power of slaves. 30

Revealingly, recent works by John Ashworth and William W. Freehling both stress this theme. Both scholars published long-awaited second volumes of their accounts of Civil War causation in 2007. Beyond this coincidence, however, it would be difficult to find two historians more dissimilar than Ashworth, a Marxist who privileges labor systems and class relations, and Freehling, a master storyteller who stresses contingency and individual consciousness. For all their methodological and ideological differences, however, Ashworth and Freehling concur on an essential point: the struggle between masters and slaves accelerated the sectional conflict by forcing masters to support undemocratic policies that threatened northern liberties. The resulting hostility of northerners toward slaveholders provoked a fierce response, and the cycle continued. By weaving the day-to-day contest between masters and slaves into their political analyses, both authors fashion a “reintegrated” American history that blends the insights of social and political history. 31

According to Ashworth, class conflict forced ruling elites in both sections to pursue clashing political and economic policies. Thus, structural divergence in social and economic systems between North and South inflamed the political and ideological strife that resulted in disunion. Class conflict was especially problematic in the South, whose enslaved population did not accept proslavery principles in the same way that, by the 1850s, some northern workers embraced free-labor ideology. Instead, interminable slave resistance compelled southern masters to gag congressional debate over slavery, to demand stringent fugitive slave laws, and to agitate for a territorial slave code—in short, to act the part of an authoritarian slave power. “Behind every event in the history of the sectional controversy,” Ashworth argues in his first volume, “lurked the consequences of black resistance to slavery.” A dozen years of additional work confirmed this thesis. In his second volume, Ashworth contends that “the opposition of the slaves to their own enslavement is the fundamental, irreplaceable cause of the War.” The Civil War did not begin as a massive slave rebellion because southern masters managed to contain the unrest that threatened their rule, but the price of this success was a deteriorating relationship with northerners. By contending for their freedom, slaves obliged their masters to behave in ways that convinced even the most bigoted northern whites that slavery menaced their own liberties. 32

colliding democratic and despotic governing systems. The Old South combined dictatorship over blacks with republicanism for whites, supposedly cleanly severed by an All-Mighty Color Line. But to preserve dictatorial dominion over blacks, the slaveholding minority sometimes trenched on majoritarian government for whites, in the nation as well as in their section. … Northerners called the militant slavocracy the Slave Power, meaning that those with autocratic power over blacks also deployed undemocratic power over whites. Most Yankees hardly embraced blacks or abolitionists. Yet racist Northerners would fight the Slave Power to the death to preserve their white men's majoritarian rights.

Scholars who foreground northern concern for white liberty in a slaveholding republic underline the importance of class conflict between northern voters and southern elites in the coming of the Civil War. Moderate antislavery northerners condemned slaveholders for aristocratic pretensions and tyrannical policies, not for racial bigotry. But for many scholars, race remains the key to understanding antebellum sectional politics. The tendency remains strong to frame the sectional conflict and the Civil War as one campaign in a longer struggle for racial justice. Not surprisingly, studies of radical abolitionism are the most likely works to employ this framework. Radical abolitionists nurtured a strikingly egalitarian conception of race and fought for a social vision that most scholars share but one that the modern world has not yet realized, and therein lies their appeal. Moreover, those who foreground race in the coming of the war do not naïvely suggest that all northern whites were racial egalitarians. Since the 1960s, commitment to an admirable antiracist ideal, not wishful thinking, has given a powerful boost to a primarily racial interpretation of the sectional conflict. But the recent scholarly emphasis on issues of class and the slave power suggests that framing the sectional conflict as a clash over racial injustice is not the most useful approach to understanding Civil War causation. 34

The slave power was defined not by racism but by slaveholders' capacity to use federal law and muscle to advance their class interests. Proslavery racism was, like all racism, reprehensible, but it is easily, even when subtly, overstated in accounts of Civil War causation. It is, for example, hardly incorrect to refer to the proslavery ideologue James Henry Hammond as “a fiercely racist South Carolina politician,” but that characterization emphasizes a trait he shared with most northern voters rather than what alienated Hammond from them and thus hastened the rise of the Republican party and the outbreak of war. What distinguished Hammond from his northern antagonists was his “mudsill” theory of society (which he outlined in an 1858 Senate speech) and its implications for American class relations. Proceeding from the presumption that every functioning society must rest upon the labors of a degraded “mudsill” class, Hammond argued that the southern laboring class, because it was enslaved, was materially better off and politically less threatening than its northern counterpart. Hammond's highly public articulation of this theory outraged proponents of free labor and made him a particularly notorious proslavery propagandist. Illinois Republicans who rallied under a banner declaring “Small-Fisted Farmers, Mud Sills of Society, Greasy Mechanics, for A. Lincoln” recognized the deep-seated class dimensions of their party's conflict with Hammond and his ilk. Moreover, Hammond's comparison of the northern and southern working classes suggests a curious ambiguity in the relative importance of class and race in proslavery ideology. This subject demands further scholarly attention, but important advances have recently been made. On the one hand, Elizabeth Fox-Genovese and Eugene D. Genovese have indicated that the irascible George Fitzhugh, who proclaimed that working people of all colors would be better off as slaves, was not alone in developing a defense of slavery compatible with racism but ultimately based on class relations. On the other hand, slaveholders, at least as much as any other antebellum Americans, benefited from portraying slavery as a fundamentally racial issue. As Frank Towers has shown, planters feared the day when nonslaveholding southern whites might begin to think in terms of class and shuddered at the prospect of working-class politics in southern cities. That one of the most strident articulations of the race-based proslavery argument—which promised that the subjugation of blacks made equals of all white men—appeared in 1860 was no coincidence, as southern elites sought to ensure regional white unity on the eve of a possible revolution. In pursuit of their interests, southern ideologues drew on both class- and race-based arguments, and if the latter stand out to modern readers, the former did more to alienate individuals in the free states. Slaveholders' conflict with northern voters, the collision that triggered secession and war, grew not out of clashing racial views but out of competition for political power. 35

The most broadly appealing brands of antislavery defined this competition as one between classes. Proponents of popular antislavery presented sectional issues in terms of class more often than race, and with tremendous effect. Their interpretation of sectional friction generated mass sympathy for a cause that otherwise would have remained a fringe movement. This moderate antislavery ideology is easily discounted if we attribute genuine antislavery sentiments only to those few northerners uncontaminated by racism. It grew from many sources: Jacksonian antipathy to concentrated economic and political power; an often-radical producerism that would guarantee to the worker the fruits of his labor; a demand for land reform that would reserve western soil for white farmers; and a morally charged concern about the fate of democracy in a nation dominated by slaveholders. Class-based Jacksonian radicalism thus informed the ideology of the Free Soil party and, crucially, the Republicans. Antislavery politicians such as New Hampshire's John P. Hale, a Democrat who drifted into the Republican ranks via the Free Soil party, “defined the controversy over slavery and its continuation as an issue between aristocratic slave owners and ‘sturdy republicans’ rather than between innocent slaves and sinful masters,” points out Jonathan H. Earle. It was this contest that aroused a northern majority to vote Lincoln into office and to enlist in the Union army. The issues of money, power, class, and democracy that concerned Jacksonian and other moderate antislavery northerners were not less morally charged because they focused on white liberty and equality in a republic. Nor should we forget that this class-based antislavery critique contained the seeds of a racial egalitarianism that sprouted, however feebly, during the Civil War. The experience of war often turned whites-only egalitarianism into a far more sweeping notion of human equality. To ignore this transformation is to discount the radicalizing influence that the Civil War had on many northern soldiers and civilians. 36

When coupled with an analysis of southern politics that emphasizes slave agency, this revival of scholarly interest in popular antislavery ideology offers not only a convincing interpretation of Civil War causation but also a politically and pedagogically important narrative about class and politics in American history. Adam Rothman's 2005 essay on the slave power is a model of this fresh and constructive approach. On one level, he presents an accessible introduction to the history and historiography of nineteenth-century slaveholders. But the chief contribution of the work lies in the context in which the essay was published: an anthology on American elite classes, from early national merchant capitalists to postwar anti–New Dealers, and their relationship with American democracy. Casting the slave power in this light gives the sectional conflict a bold new meaning, one that reveals the Civil War to have been both much more than and much less than a precursor to the civil rights movement. It appears as a struggle between (an imperfect) popular democracy and one of the most powerful and deeply rooted interests in antebellum politics. One might argue that Americans simply replaced one set of masters—southern planters—with another, the rising robber barons. Nevertheless, the Civil War offers one of precious few instances in American history in which a potent, entrenched, incredibly wealthy, and constitutionally privileged elite class was thoroughly ousted from national power. This makes the class-based issues that helped spark the war too important to forget. 37

That narrative may also aid in the quest for that holy grail of academic history: a receptive public audience. The neo-Confederate outcry against the alleged anti-southern bias of McPherson's 2000 “What Caused the Civil War?” essay and the ongoing controversy over the Confederate flag indicate that much of the public does not share in the scholarly consensus on slavery's central place in Civil War causation. Unfortunately, no quick fix exists for popular misconceptions about the war, but scholarship that frames the conflict over slavery as a struggle in which the liberties of all Americans were at stake may influence minds closed to depictions of the war as an antiracist crusade. This is not to argue that historians should pander to popular prejudice or that race is not a central theme in the history of the Civil War era. Rather, historians can and should capitalize on the political and pedagogical advantages of an important body of scholarship that sharpens our understanding of Civil War causation by explaining why even incorrigible northern racists voted and fought against southern slaveholders, and that reminds us that slavery impacted all antebellum Americans, North and South, black and white. When northerners urged the “necessity” of defending their liberty against the encroaching “tyranny” of a government “under the absolute control of an oligarchy of southern slave holders,” as Judge F. C. White of Utica, New York, wrote in 1858, they meant precisely what they said. To gainsay the salience of race in the causes, course, and outcome of the Civil War would be a terrible mistake, but it would be equally misleading to neglect the matters of class, power, and democracy at the heart of the slavery debate; these issues contributed mightily to the origins of the nation's bloodiest conflict and to its modern-day significance. 38

Whatever its ultimate fate in the classroom and public discourse, recent scholarship on the coming of the Civil War reveals an impatience with old interpretive categories, an eagerness to challenge the basic parameters that have long guided scholarly thinking on the topic, and a healthy skepticism of narratives that explain the war with comforting, simplistic formulae. The broad consensus on slavery's centrality has not stifled rapid growth and diversification in the field. Indeed, the proliferation of works on Civil War causation presents a serious challenge to anyone seeking to synthesize the recent literature into a single tidy interpretation. Rather than suggest an all-encompassing model, this essay has outlined three broad themes that could provide fertile ground for future debate. A reaction against the expanding geographic and temporal breadth of Civil War causation studies, for example, might prompt scholars to return to tightly focused, state-level analyses of antebellum politics. Recent political histories of antebellum Mississippi and Louisiana suggest that this approach has much to contribute to our understanding of how national debates filtered down to state and local levels. Other scholars might take an explicitly comparative approach and analyze the causes, course, and results of the American Civil War alongside those of roughly contemporaneous intrastate conflicts, including the Reform War (1857–1861) in Mexico and China's Taiping Rebellion (1850–1864). Comparative history's vast potential has been amply demonstrated by Enrico Dal Lago's study of agrarian elites and regionalism in the Old South and Italy, and by Don H. Doyle's edited collection on secession movements around the globe. Similarly, scholars undoubtedly will challenge the interpretive emphases on proslavery American nationalism, antislavery northern sectionalism, and the class dimensions of the sectional conflict that pervade much of the recent scholarship and receive close attention in this essay. But others might carry on this work by studying phenomena such as the disunionist thrust of radical abolitionism. The campaign for free-state secession never sank deep roots in northern soil. But by the late 1850s it was a frequent topic of editorials in abolitionist publications such as the National Anti-Slavery Standard, and it captured mainstream headlines through events such as the 1857 Worcester Disunion Convention. And even if race, southern sectionalism, and northern Unionism dominate future narratives of Civil War causation, further debate will sharpen our analysis of an easily mythologized period of American history. 39

These debates will be no less meaningful because of scholars' near-universal acknowledgement of the centrality of slavery in the coming of the Civil War. Instead, they illustrate C. Vann Woodward's observation that “most of the important debates over history … have not been about absolute but about relative matters, not about the existence but about the degree or extent of the phenomenon in question.” Beneath a veneer of consensus lies interpretive nuance and healthy disagreement, which we can hope will inform both academic and popular commemoration of the Civil War sesquicentennial. 40

For more recent historiographical assessments of specific topics related to the sectional crisis, see Lacy K. Ford, ed., A Companion to the Civil War and Reconstruction (Malden, 2005), 25–200. For a reinterpretation of the full century and a half of scholarship on Civil War causation that briefly samples recent literature, see Frank Towers, “Partisans, New History, and Modernization: The Historiography of the Civil War's Causes, 1861–2011,” Journal of the Civil War Era, 1 (June 2011), 237–64. Several important bodies of literature are underrepresented in my historiography. One is work on the five months between Abraham Lincoln's election and the bombardment of Fort Sumter, which addresses the question of why and how secession sparked a shooting war. This outcome was not inevitable, because the causes of disunion were not identical to the causes of the Civil War itself. This essay focuses on the former topic. For recent interpretations of the latter, see Dew, Apostles of Disunion; David Detzer, Allegiance: Fort Sumter, Charleston, and the Beginning of the Civil War (New York, 2001); Larry D. Mansch, Abraham Lincoln, President-Elect: The Four Critical Months from Election to Inauguration (Jefferson, 2005); Nelson D. Lankford, Cry Havoc! The Crooked Road to Civil War, 1861 (New York, 2007); Russell McClintock, Lincoln and the Decision for War: The Northern Response to Secession (Chapel Hill, 2008); Harold Holzer, Lincoln President-Elect: Abraham Lincoln and the Great Secession Winter, 1860–1861 (New York, 2008); Lawrence M. Denton, William Henry Seward and the Secession Crisis: The Effort to Prevent Civil War (Jefferson, 2009); William J. Cooper Jr., “The Critical Signpost on the Journey toward Secession,” Journal of Southern History, 77 (Feb. 2011), 3–16; Emory M. Thomas, The Dogs of War, 1861 (New York, 2011); and Adam Goodheart, 1861: The Civil War Awakening (New York, 2011). Biographies are also not explored systematically here. Recent biographies related to the coming of the Civil War include William C. Davis, Rhett: The Turbulent Life and Times of a Fire-Eater (Columbia, S.C., 2001); John L. Myers, Henry Wilson and the Coming of the Civil War (Lanham, 2005); John M. Belohlavek, Broken Glass: Caleb Cushing and the Shattering of the Union (Kent, 2005); Eric H. Walther, William Lowndes Yancey and the Coming of the Civil War (Chapel Hill, 2006); and Denton, William Henry Seward and the Secession Crisis . Thanks in part to the close proximity of Lincoln's bicentennial birthday and the Civil War sesquicentennial, scholarship on the sixteenth president continues to burgeon. For analyses of this vast literature, see James Oakes, “Lincoln and His Commas,” Civil War History, 54 (June 2008), 176–93; Sean Wilentz, “Who Lincoln Was,” New Republic, July 15, 2009, pp. 24–47; and Nicole Etcheson, “Abraham Lincoln and the Nation's Greatest Quarrel: A Review Essay,” Journal of Southern History, 76 (May 2010), 401–16. For an account of Lincoln historiography in the Journal of American History, see Allen C. Guelzo, “The Not-So-Grand Review: Abraham Lincoln in the Journal of American History, ” Journal of American History, 96 (Sept. 2009), 400–416. That biography and studies of the secession winter are thriving suggests a possible waning of the long-dominant “irrepressible conflict” interpretation, as both approaches emphasize contingency and individual agency. Collective biography, particularly on Lincoln's relationships with other key figures, has also flourished. On Lincoln and Frederick Douglass, see James Oakes, The Radical and the Republican: Frederick Douglass, Abraham Lincoln, and the Triumph of Antislavery Politics (New York, 2007); Paul Kendrick and Stephen Kendrick, Douglass and Lincoln: How a Revolutionary Black Leader and a Reluctant Liberator Struggled to End Slavery and Save the Union (New York, 2008); and John Stauffer, Giants: The Parallel Lives of Frederick Douglass and Abraham Lincoln (New York, 2008). On Lincoln and Stephen A. Douglas, see Allen C. Guelzo, Lincoln and Douglas: The Debates That Defined America (New York, 2008); and Roy Morris, The Long Pursuit: Abraham Lincoln's Thirty-Year Struggle with Stephen Douglas for the Heart and Soul of America (New York, 2008). A third body of literature that needs further historiographical analysis relates to gender and the coming of the Civil War. See, for example, Michael D. Pierson, Free Hearts and Free Homes: Gender and American Antislavery Politics (Chapel Hill, 2003); Nina Silber, Gender and the Sectional Conflict (Chapel Hill, 2008); Kristen Tegtmeier Oertel, Bleeding Borders: Race, Gender, and Violence in Pre–Civil War Kansas (Baton Rouge, 2009); and Stephanie McCurry, Confederate Reckoning: Power and Politics in the Civil War South (Cambridge, Mass., 2010). For discussions of the classic schools of scholarship, see Kenneth M. Stampp, “The Irrepressible Conflict,” in The Imperiled Union: Essays on the Background of the Civil War, by Kenneth M. Stampp (New York, 1980), 191–245; Ayers, What Caused the Civil War?, 132–33; and Gary J. Kornblith, “Rethinking the Coming of the Civil War: A Counterfactual Exercise,” Journal of American History, 90 (June 2003), 78–79. For a call for a synthesis of the fundamentalist and revisionist interpretations, see Ayers, What Caused the Civil War? On the continued relevance of these camps, see James Huston, “Interpreting the Causation Sequence: The Meaning of the Events Leading to the Civil War,” Reviews in American History, 34 (Sept. 2006), 329. The coming of the Civil War has long shaped discussions of historical causation, including Lee Benson and Cushing Strout, “Causation and the American Civil War: Two Appraisals,” History and Theory, 1 (no. 2, 1961), 163–85; and William Dray and Newton Garver, “Some Causal Accounts of the American Civil War,” Daedalus, 91 (Summer 1962), 578–98.

Other recent transnational studies of Civil War causation include Timothy Roberts, “The European Revolutions of 1848 and Antebellum Violence in Kansas,” Journal of the West, 44 (Fall 2005), 58–68; Gerald Horne, The Deepest South: The United States, Brazil, and the African Slave Trade (New York, 2007); McCurry, Confederate Reckoning; and Mischa Honeck, We Are the Revolutionists: German-Speaking Immigrants and American Abolitionists after 1848 (Athens, Ga., 2011). Several recent dissertations explore the equally permeable boundary between North and South. See Joseph T. Rainer, “The Honorable Fraternity of Moving Merchants: Yankee Peddlers in the Old South, 1800–1860” (Ph.D. diss., College of William and Mary, 2000); Wesley Brian Borucki, “Yankees in King Cotton's Court: Northerners in Antebellum and Wartime Alabama” (Ph.D. diss., University of Alabama, 2002); Eric William Plaag, “Strangers in a Strange Land: Northern Travelers and the Coming of the American Civil War” (Ph.D. diss., University of South Carolina, 2006); and Alana K. Bevan, “‘We Are the Same People’: The Leverich Family of New York and Their Antebellum American Inter-regional Network of Elites” (Ph.D. diss., Johns Hopkins University, 2009). On the “mighty experiment,” see Seymour Drescher, The Mighty Experiment: Free Labor versus Slavery in British Emancipation (New York, 2002). The compelling scholarship on global antislavery undoubtedly encouraged the internationalization of Civil War causation studies. David Brion Davis's contributions remain indispensable. See David Brion Davis, The Problem of Slavery in Western Culture (Ithaca, 1966); David Brion Davis, The Problem of Slavery in the Age of Revolution, 1770 –1823 (Ithaca, 1975); and David Brion Davis, Inhuman Bondage: The Rise and Fall of Slavery in the New World (New York, 2006).

John Majewski offers a different perspective on slavery and free trade, acknowledging that slaveholders were hardly united in favor of protection and arguing that the moderate Confederate tariff represented a compromise between protectionists and free traders. See John Majewski, Modernizing a Slave Economy: The Economic Vision of the Confederate Nation (Chapel Hill, 2009).

Causes of the American Civil War?

Now as a Brit with an interest in pretty much all history I've started looking at the American Civil War. However, I've yet to find a good, well explained and easy to digest list of the causes and lead up to the war. Some argue that slavery was a cause (which seems doubtful), states rights, Lincoln's election etc. So have at it. What were the causes of the American Civil War?

The war of the United States with Spain was very brief. Its results were many, startling, and of world-wide meaning. --Henry Cabot Lodge

what were the main causes of the civil war essay

On April 25, 1898 the United States declared war on Spain following the sinking of the Battleship Maine in Havana harbor on February 15, 1898. The war ended with the signing of the Treaty of Paris on December 10, 1898. As a result, Spain lost its control over the remains of its overseas empire -- Cuba, Puerto Rico, the Philippines Islands, Guam, and other islands.

Beginning in 1492, Spain was the first European nation to sail westward across the Atlantic Ocean, explore, and colonize the Amerindian nations of the Western Hemisphere. At its greatest extent, the empire that resulted from this exploration extended from Virginia on the eastern coast of the United States south to Tierra del Fuego at the tip of South America excluding Brazil and westward to California and Alaska. Across the Pacific, it included the Philippines and other island groups. By 1825 much of this empire had fallen into other hands and in that year, Spain acknowledged the independence of its possessions in the present-day United States (then under Mexican control) and south to the tip of South America. The only remnants that remained in the empire in the Western Hemisphere were Cuba and Puerto Rico and across the Pacific in Philippines Islands, and the Carolina, Marshall, and Mariana Islands (including Guam) in Micronesia.

Following its declaration of war against Spain issued on April 25, 1898, the United States added the Teller Amendment asserting that it would not attempt to exercise hegemony over Cuba. Two days later Commodore George Dewey sailed from Hong Kong with Emilio Aguinaldo on board. Fighting began in the Phillipines Islands at the Battle of Manila Bay on May 1 where Commodore George Dewey reportedly exclaimed, "You may fire when ready, Gridley," and the Spanish fleet under Rear Admiral Patricio Montojo was destroyed. However, Dewey did not have enough manpower to capture Manila so Aguinaldo's guerrillas maintained their operations until 15,000 U.S. troops arrived at the end of July. On the way, the cruiser Charleston stopped at Guam and accepted its surrender from its Spanish governor who was unaware his nation was at war. Although a peace protocol was signed by the two belligerents on August 12, Commodore Dewey and Maj. Gen. Wesley Merritt, leader of the army troops, assaulted Manila the very next day, unaware that peace had been declared.

In late April, Andrew Summers Rowan made contact with Cuban General Calixto García who supplied him with maps, intelligence, and a core of rebel officers to coordinate U.S. efforts on the island. The U.S. North Atlantic Squadron left Key West for Cuba on April 22 following the frightening news that the Spanish home fleet commanded by Admiral Pascual Cervera had left Cadiz and entered Santiago, having slipped by U.S. ships commanded by William T. Sampson and Winfield Scott Schley. They arrived in Cuba in late May.

War actually began for the U.S. in Cuba in June when the Marines captured Guantánamo Bay and 17,000 troops landed at Siboney and Daiquirí, east of Santiago de Cuba, the second largest city on the island. At that time Spanish troops stationed on the island included 150,000 regulars and 40,000 irregulars and volunteers while rebels inside Cuba numbered as many as 50,000. Total U.S. army strength at the time totalled 26,000, requiring the passage of the Mobilization Act of April 22 that allowed for an army of at first 125,000 volunteers (later increased to 200,000) and a regular army of 65,000. On June 22, U.S. troops landed at Daiquiri where they were joined by Calixto García and about 5,000 revolutionaries.

U.S. troops attacked the San Juan heights on July 1, 1898. Dismounted troopers, including the African-American Ninth and Tenth cavalries and the Rough Riders commanded by Lt. Col. Theodore Roosevelt went up against Kettle Hill while the forces led by Brigadier General Jacob Kent charged up San Juan Hill and pushed Spanish troops further inland while inflicting 1,700 casualties. While U.S. commanders were deciding on a further course of action, Admiral Cervera left port only to be defeated by Schley. On July 16, the Spaniards agreed to the unconditional surrender of the 23,500 troops around the city. A few days later, Major General Nelson Miles sailed from Guantánamo to Puerto Rico. His forces landed near Ponce and marched to San Juan with virtually no opposition.

Representatives of Spain and the United States signed a peace treaty in Paris on December 10, 1898, which established the independence of Cuba, ceded Puerto Rico and Guam to the United States, and allowed the victorious power to purchase the Philippines Islands from Spain for $20 million. The war had cost the United States $250 million and 3,000 lives, of whom 90% had perished from infectious diseases.
