What was the Kansas-Nebraska Act?

The Kansas-Nebraska Act of 1854 was a territorial measure drafted by Senator Stephen A. Douglas that created the Kansas and Nebraska territories and repealed the Missouri Compromise. By introducing the concept of popular sovereignty to determine the legality of slavery in these new lands, the law deeply outraged Northerners and shattered the existing political party system. The resulting violent clashes in Kansas and the intense political polarization served as major stepping stones toward the American Civil War.
