Missouri is called the "Show Me State," because its people have a reputation for believing only what they see. Its name is an Algonquin Indian term meaning "river of the big canoes." Originally home to a number of Indian tribes, the state entered the Union on August 10, 1821 as a slave state after an agreement known as the Missouri Compromise in which Maine was admitted as a free state. Today, more than half the population lives in Missouri's two major cities--Kansas City and St. Louis. The dogwood is the Missouri state tree, the bluebird is the Missouri's state bird and the capital is Jefferson City.
