Kansas-Nebraska Act

Popular sovereignty expansion

The Kansas-Nebraska Act was an 1854 U.S. law that created the Kansas and Nebraska territories and allowed settlers there to decide whether to permit slavery—effectively repealing the Missouri Compromise's ban on slavery north of a certain latitude.

The act inflamed sectional tensions over slavery and contributed directly to the formation of the Republican Party and the onset of the Civil War.
