Conference Committee Report on the Missouri Compromise, March 1, 1820

When Missouri, which allowed slavery, applied for statehood in 1819 Congress struggled for a way to maintain the Union despite strongly opposing pro- and anti-slavery constituencies. After heated debate, Congress adopted the Missouri Compromise, which admitted Maine as a free state to balance Missouri and prohibited slavery north of the 36º 30´ latitude in the Louisiana Territory.

…in all that Territory…under the name of Louisiana, which lies north of thirty six degrees and thirty minutes north latitude…Slavery and involuntary Servitude…shall be and is hereby forever prohibited.
