Kansas Nebraska Act. This Act set up Kansas and Nebraska as states. Each state would use popular sovereignty to decide what to do about slavery. People who were pro-slavery and antislavery moved to Kansas, but some antislavery settlers were against the Act.
The Kansas-Nebraska Act also led to Bleeding Kansas, a mini civil war that erupted in Kansas in 1856. Northerners and Southerners flooded Kansas in 1854 and 1855, determined to convert the future state to their view on slavery.
