Sectional tension began when the North and the South had very different opinions on whether to have slaved states or free states. The North were against having enslaved people, and were a free nation. The South supported having enslaved people. The reasons that the nation split apart was due to the Missouri Comporomise, Fugitive Slave and the Kansas-Nebraska Act.
The Missouri Compromise had ll free states and 11 slaved states. The North and the South, having their differences grew into sectionalism. Missouri wanted to join as a slave state, but that would anger the Congress because they wanted an even balance on slaved and free states. So Maine joined in as a free state to balance it out. The Senate wanted to settle the issue of slavery in the territories for good so there was a 36*30’N latitude line to seperate the free and slaved states for the North and the South.
In addition to the reason why the nation split is due to the Fugitive Slave Act. This was a law part of the Compromise of 1850. This required people to help catch fugitives, anyone who aided fugitives could be fined or imprisoned. Slaveholders stepped up their efforts to catch runaways. Antislavery groups tried to rescue enslaved African Americans that were running away from being captured through the Underground Railroad.
Last, but not least to the reason why the nation split was due to the Kansas-Nebraska Act. Kansas and Nebraska both were free states since they were North of the 36*30N’ latitude line, but the North wanted them to be a free state, and the South wanted them to be slaved. Stephen A. Douglas proposed letting settlers in each territory to vote on whter to allow slavery calling it popular sovereignty. Border ruffians traveled across the border to vote in the election. The Kansas-Nebraska Act then became known as the “Bleeding Kansas” because the people there called it a “civil war” in the conflict between the citizens of the same country.
