Kansas.
The Missouri Compromise was effectively ended by the Kansas-Nebraska Act, however since there was still turmoil as to the "Bleeding Kansas" dispute, it was thought that the Kansas-Nebraska Act would be shortly overturned. The Dred Scott decision by the Supreme Court further strengthened the elimination of the Missouri Compromise and the institution of slavery north of the Mason-Dixon Line by ruling that slaves were not able to take cases to court.
