The south wanted to leave so they could keep their economy based on free labor from slavery. The Kansas Nebraskas act passed in March 1854 let the people in those territories decide the issue for themselves ( if they wanted slavery or not) which pissed off the North which saw it as a violation of the Missouri Compromise which was suppoed to keep slavery below the 36 30 lattitude line. This takes us to Bleeding Kansas, which was the settlers fighting over the issue, then Harpers Ferry, John Browns execution, the fort sumter attack and then civil war but basiclly it comes down to rich white slave owners being too cheap to pay for field hands.. . .
