Missouri Counties

Missouri has one hundred and fourteen counties and one independent city. St. Louis City is separate from St. Louis County and is referred to as a "city not within a county." Following the Louisiana Purchase and the admittance of Louisiana into the United States in 1812, five counties were formed out of the Missouri Territory at the first general assembly. Most subsequent counties were apportioned from these five original counties.

History of Mississippi County

A county on the Mississippi River created by the state legislature February 14, 1845, the territory being cut off from the southern part of Scott County. Charleston was selected as the county seat and the boundaries of the townships of Tywappity, St. James and St. James Bayou, which had belonged to Scott County, were changed and two new townships, Mississippi and Wolf Island were created. Ohio Township was created from Mississippi Township in 1847. The county was named from the Mississippi River (q.v.) (Douglass I 311, M.H.R. 11:330-331)
