The Jackson Purchase is a region in the western part of Kentucky, named after President Andrew Jackson. It was acquired from the Chickasaw Nation in 1818, following a treaty that allowed settlers to move into the area. This land is known for its fertile soil and has played a significant role in agriculture, particularly in the production of tobacco and corn. The Jackson Purchase covers several counties, including Calloway, Marshall, and Carlisle. It is bordered by the Tennessee state line to the south and the Ohio River to the north. The region has a rich history, with influences from Native American cultures and early American settlers.
