On this day in 1819 The United States House of Representatives passes the Missouri Compromise for the first time.
To balance the number of “slave states” and “free states,” the northern region of what was then Massachusetts ultimately gained admittance into the United States as a free state to become Maine. This only occurred as a result of a compromise involving slavery in Missouri, and in the federal territories of the American west. A bill to enable the people of the Missouri Territory to draft a constitution and form a government preliminary to admission into the Union came before the House of Representatives in Committee of the Whole, on February 13, 1819. James Tallmadge of New York offered an amendment, named the Tallmadge Amendment that forbade further introduction of slaves into Missouri, and mandated that all children of slave parents born in the state after its admission should be free at the age of 25. The committee adopted the measure and incorporated it into the bill as finally passed on February 17, 1819, by the house. The United States Senate refused to concur with the amendment, and the whole measure was lost.
