The fugitive slave act angered many northerners who wanted to obtain equality, for it made it so that freed African Americans were sent back down to the South to work yet again in the system of slavery. The Kansas Nebraska Act was put into place so that Stephen Douglas would be able to have his transcontinental railroad in the north. It made it so that the Kansas and Nebraska territories were no longer free states, and were now up to popular sovereignty - meaning whether or not slavery would exist there now depended on a vote. The Kansas Nebraska Act ended up causing the Sack of Lawrence where Missourians who had been planning to go up to Kansas to throw the vote in favor of being a slave state, found out that some northerners had also planned on this, and had set up camp in the city of Lawrence. About 800 southern men marched up to Lawrence to get rid of the northerners - only to find that the northerners had heard of this and fled. Angered, the southern men ransacked and burned down the town. The Sack of Lawrence then caused the North to retaliate with the Pottawatomie Massacre. In the Pottawatomie Massacre, John Brown and a small group of his followers marched up to southern men's homes and murdered them.
