Tallmadge Amendment sparks the Missouri controversy (1819)

The Tallmadge Amendment, introduced in the U.S. House of Representatives in February 1819, proposed admitting Missouri as a free state. It passed the House but the Senate blocked a restrictionist state, producing a stalemate that carried into the 1820 Missouri Compromise, which was enacted without the amendment.

Background and detail

Background. By 1819, Missouri Territory approached the population threshold for statehood. Southern planters had increased the slave population significantly. The amendment aimed to restrict the political weight of the slaveholding South in Congress, reflecting tensions over the balance of power between free and slave states.

Legislative Process. The amendment was introduced in the House on February 13, 1819. On February 16 the Committee of the Whole voted to link Tallmadge's provisions to the statehood bill, and the House passed the measure on February 17, 1819. The recorded sectional breakdown of 86-10 northern support and 66-1 southern opposition describes the 87-76 passage vote.

Stalemate and Resolution. The Senate blocked a state that restricted slavery, and the House refused to concur, so the 15th Congress adjourned on March 4, 1819 without acting on Missouri's statehood. The issue devolved to the 16th Congress, where the Missouri Compromise was passed in 1820 without the Tallmadge Amendment, admitting Missouri as a slave state and Maine as a free state.
