The '''Kansas-Nebraska Act''' was an 1854 law opening the [[US]] territories of [[Kansas]] and [[Nebraska]] to [[popular sovereignty]], the idea that the states' residents would decide whether or not to allow [[slavery]]. This nullified the earlier [[Missouri Compromise]], as Kansas and Nebraska were north of the compromise line. The Act was largely a response to [[Bleeding Kansas]], where anti-slavery and pro-slavery militias clashed in Kansas. | The '''Kansas-Nebraska Act''' was an 1854 law opening the [[US]] territories of [[Kansas]] and [[Nebraska]] to [[popular sovereignty]], the idea that the states' residents would decide whether or not to allow [[slavery]].
