Missouri is a state in the Midwestern region of the United States. Missouri is the eighteenth most populous state. It comprises 114 counties and one independent city. Missouri's capital is Jefferson City. The largest city is Kansas City, and the four largest urban areas are, in descending order, St. Louis, Kansas City, Springfield, and Columbia. Missouri was originally purchased from France as part of the Louisiana Purchase and part of the Missouri Territory was admitted into the union as the 24th state in 1821.
The University of Missouri was created in 1839. Six years later, St. Louis was connected by telegraph to the east coast. The same year, the first bank west of the Mississippi was established.
The California Gold Rush began in 1848 and Saint Louis, Independence, Westport and Saint Joseph became departure points for those heading to California, earning Missouri the nickname "Gateway to the West". Kansas City was incorporated a year later on the banks of the Missouri River.
The flag consists of three horizontal stripes of red, white and blue. These represent valor, purity, vigilance, and justice. The colors also reflect the state's historic status as part of the French Louisiana Territory. In the center white stripe is the Seal of Missouri, circled by a blue band containing 24 stars, symbolizing Missouri's admission as the 24th U.S. state.
