Jackson County was created in 1914 with the county seat at Kadoka. Previous to this time it was a part of Stanley County. Early historical sketches indicate Jackson County was named for President Andrew Jackson; however, it is now considered certain that it was named for J. R. Jackson, a member of the Territorial Legislature when the original Jackson County was created in 1883. Following the various legislative shuffles Jackson vanished from the map. First, the northern part of Jackson was joined to Stanley County and the southern half part of Washabaugh. Finally in 1914 Stanley County was split up and Jackson County was reborn as it is today
