Chickasaw Territory – Jackson Purchase
The land west of the Tennessee River and south of the Ohio was regarded as Chickasaw territory during the early and pre-statehood period. In 1818 Isaac Shelby and Andrew Jackson negotiated the purchase of the region in western Kentucky and western Tennessee, about 6,000 square miles, from the Chickasaw for $300,000. The Kentucky land was initially an extension to Christian county, but was later subdivided into several counties. This part of Kentucky is known as the Jackson Purchase.
