The Kansas-Nebraska Act
The law that repealed the Missouri Compromise and set Kansas bleeding, 1854
May 30, 1854
The Kansas-Nebraska Act of 1854 created the territories of Kansas and Nebraska and let their settlers decide whether to allow slavery — repealing the Missouri Compromise, which had banned slavery there. Proslavery and antislavery settlers rushed into Kansas, and the conflict turned so violent it became known as “Bleeding Kansas.” Outrage over the act led to the founding of the Republican Party and pushed the country closer to civil war.

Why it matters
Antislavery Northerners were outraged that a ban on slavery in place for thirty-four years had been swept away. Proslavery and antislavery settlers raced into Kansas to control its first elections, and fraud and violence — including the killings involving John Brown — followed. The act shattered the Whig Party; its opponents formed the Republican Party, dedicated to stopping the spread of slavery into the territories, which elected Abraham Lincoln six years later. The National Archives concludes that the act aggravated the split between North and South until reconciliation seemed virtually impossible.
Historical circumstances
Stephen Douglas wanted to organize the land west of Missouri, partly to promote a transcontinental railroad route through the North. To win Southern votes, his bill applied popular sovereignty to the new territories — even though both lay north of the 36°30′ line where the Missouri Compromise had prohibited slavery. Douglas introduced the bill in January 1854, and after months of debate it passed on May 30.
Principal ideas
- Two territories. Kansas and Nebraska were organized from the land immediately west of Missouri.
- Popular sovereignty. Settlers, through their territorial legislatures, would decide whether to permit slavery.
- Repeal of the Missouri line. The act declared the Missouri Compromise’s ban on slavery north of 36°30′ inoperative.
