The Missouri Compromise Line was a boundary established by the Missouri Compromise of 1820, which aimed to resolve conflicts over the expansion of slavery into new territories. It designated a line at latitude 36ยฐ30' north, where slavery would be permitted in the territory south of the line and prohibited in the territory north of it. This compromise played a crucial role in shaping the political landscape leading up to the events of the Election of 1860 and subsequent secession movements.
