This county was organized in 1826 and named for Andrew Jackson (1767-1845). Conard states that most of the land in the western part was acquired directly from Indian tribes by a treaty signed June 2, 1825. The eastern part had been a part of Lillard County, the present Lafayette County. From 1827 to 1835 the territory of Jackson included that of Cass and Bates counties. Miss Johnson states in her thesis that Bates was organized and named in 1833, although for civil and military purposes it was attached to Jackson County until 1841. Cass County was separated from Jackson in 1835. Today the county is bounded on the north by Clay County and a part of Ray County, from which the two counties it is separated by the Missouri River. Lafayette County and a part of Johnson County bound it on the east, Cass County on the south, and Johnson and Wyandotte counties of Kansas, on the west. (LAWS OF MISSOURI 1826; HIST.
