Timeline of events leading to the American Civil War

A timeline of events leading up to the American Civil War describes the events which historians recognize as contributing to the American Civil War. Many of these events lead back to the founding of the country. The United States Constitution makes only a few mentions of slavery leaving it largely up to the individual states to govern it. As the Northern and Southern United States developed along separate lines, slavery eventually disappeared from the North. It became an institution in the South. As new parts of the country opened up to settlement the issues over slavery started a long-standing controversy between North and South. It became a burning issue and led to secession of several Southern states. This in general led to the Civil War.

They persuade the Virginia General Assembly to discuss a prohibition of slavery or a ban on importing slaves.

 Key events that triggered the war 
1850 The Compromise of 1850 held off outright hostilities between North and South but did little to fix the problems. The Fugitive Slave Act of 1850 forced non-slaveowners to participate in slavery which increased tensions over the issue.1852 Uncle Tom's Cabin is published by Harriet Beecher Stowe. It was the second-best-selling book of the 19th century in America. In the North it opened many eyes to the horrors of slavery. In the South it was considered to be Slander.1854 The Kansas-Nebraska Act is passed which repeals the Compromise of 1820. It creates the territories of Kansas and Nebraska. It also allowed the states to vote on whether slavery was legal or not.1854-1860 Bleeding Kansas was the immediate result of the Kansas-Nebraska act. It overturned the Missouri Compromise of 1820 in that it allowed the settlers of the new territories to decide for themselves whether slavery would be allowed or not. It caused a rush of pro-slavery and anti-slavery groups into Kansas to try to influence the voting. It turned into an ugly war between groups of people who held strong opinions both for and against slavery.1857 Dred Scott v. Sandford was a decision by the Supreme Court of the United States. They ruled that African Americans, whether free or slaves, were not citizens of the United States. Because they were not citizens they could not sue in a Federal court. The ruling was a major setback to the anti-slavery movement. The Republicans condemned the ruling.

They were led by Colonel Robert E. Lee.1860 November 6 - Abraham Lincoln is elected President of the United States.
