By 1819, the population of Missouri had grown to the point where it was ready for statehood. Ten thousand slaves already lived in Missouri. As such, It was assumed Missouri would become a slave state. On February 13th James Tallmadge, a Congressman from Poughkeepsie, New York, introduced a resolution in Congress making two modifications to the Missouri Enabling Act (The Enabling Act would give Missouri statehood). This act would ban any further importation of slaves into Missouri. It would also set in motion the gradual emancipation of the slaves currently residing in Missouri. Raising these modifications, a one term Congressman began a battle over slavery that was only ended by the Civil War. Obviously the Tallmadge amendment was not acceptable to the Southern states. The Congress was deadlocked until a compromise could be found. That compromise became known as “The Missouri Compromise”. Under the terms of the compromise, Missouri was to be admitted as a slave state, while Maine was admitted as a free state. The rest of the territory acquired from France (north of the latitude 36’30’) would be free states, while south of that point would be slave states.
The Missouri Compromise (1819) set a number of precedents. First, states would enter the Union in pairs– a slave state and a free state. This compromise helped the Southern states, as they were often admitted to the Union sooner than they would normally have been admitted (in order to keep the balance). Second, the Missouri Compromise delayed the sectional breakup of the Jefferson’s Republican party. The battle over Missouri signified a solidification of the Southern opposition to the eventual emancipation of the slaves. Until the fight over Missouri’s admission to the Union, there was some hope the South would follow the path indicated by many of the founders; a path leading to the eventual voluntary emancipation of all slaves. By the time the Missouri Compromise was reached, it was clear this was not meant to be.
