The event that ended the Missouri Compromise and made violence between pro- and anti-slavery groups more likely was the Kansas-Nebraska Act. Passed in 1854, this act repealed the Missouri Compromise by allowing the territories of Kansas and Nebraska to decide for themselves whether to allow slavery through the principle of popular sovereignty. This led to significant conflict, known as "Bleeding Kansas," as pro- and anti-slavery settlers moved into the territories to influence the decision, resulting in violent confrontations.
