Most of Missouri is already in the Northern area where slavery is banned and if Missouri did enter the union, Northerns thought that it could spread throughout the whole entire Louisiana Purchase. The Southerners thought that Congress has no right to prevent slave owners from keeping slaves in a state. Northern people were thought to be trying to end slavery.

A man named Nat Turner made a slave rebellion but then more than 50 white people were killed. Fears of further violence led to stricter slave laws. Meanwhile, enslaved people continued to protect their rights by running and some generous Northerners were able to help them escape. After America fought a war with Mexico and won, the US needed to decide if they would allow slavery in that area or not. The North thought the Mexican Cession should be a free territory or the new territory should be decided by popular sovereignty. The South believed that all of the Mexican Cession should be open to slavery or the Missouri Compromise line should be extended all the way to the Pacific coast. The final compromise was that the North would have California added to the union but as a free state and the slave trade in Washington DC would end (slavery itself did not). For the South, the Fugitive Act was passed. This act made it easier for slave owners to find and take back slaves who've escaped. The Mexican Cession was divided into two territories, New Mexico and Utah would be decided if it was free or not by popular soverginty.
