Explanation:

The Law of Kansas-Nebraska was the law promulgated in the United States, in 1854, for the creation of the states of Nebraska and Kansas, in territories of the old French Louisiana, but in which they remained some tribes of Indians. It was driven by the senator and leader of the Democratic party Stephen Arnold Douglas, of Illinois.

The Kansas-Nebraska Act effectively nullified the Missouri Compromise of 1820, and although it failed to make Kansas a state with legal slave labor, it further opened up the nation's divisions that led to the Civil War of 1861. Kansas was admitted as a free state on January 29, 1861, but Nebraska was not admitted as a state until after the Civil War, in 1867.

The Kansas-Nebraska Act was passed by the U. S. Congress on May 30, 1854. It allowed people in the territories of Kansas and Nebraska to decide for themselves whether or not to allow slavery within their borders. The Act served to repeal the Missouri Compromise of 1820 which prohibited slavery north of latitude 36°30'.
