The Compromise of 1850 made California a free state, made New Mexico and Utah free sovereignty states, ended the slave trade in Washington D.C. and made it easier for southerners to recover fugitive slaves.
The Kansas-Nebraska Act was passed by congress in 1854, and it enabled citizens of Kansas and Nebraska to decide whether or not they would allow slavery within their borders. Proslavery and antislavery members rushed to these states to win the majority for their view.
Bleeding Kansas was an event that occurred because of the Kansas-Nebraska act. When antislavery and proslavery citizens arrived in Kansas they fought over who would settle there and then decide whether Kansas was a slave state or a free state.
