Missouri Territory




The Missouri Territory was a historic, Organized Territory in the United States . It was originally known as the Louisiana Territory and was renamed on June 4 , 1812 to avoid confusion with the state of Louisiana which joined the Union in 1812. The Arkansas Territory was separated from the Missouri Territory in 1819 . The state of Missouri was separated out from the territory in August 10 , 1821 .

The remaining portion, consisting of the present states of Iowa , The Dakotas , and part of Minnesota effectively became Unorganized Territory after Missouri became a state. In 1834 the remaining territory was attached to the Michigan Territory .
