What year did Missouri become a state?

Missouri became a state on August 10, 1821. This marked its admission as the 24th state to join the United States. The process leading to statehood began with the Missouri Compromise of 1820, which addressed the contentious issue of slavery and allowed Missouri to enter as a slave state while Maine was admitted as a free state. This historical context is crucial as it highlights the political landscape and compromises of that era. The date of August 10, 1821, represents an important moment in both Missouri's history and the broader framework of American state development.
