History

Formed in 1816 from Clark County, Jefferson County and Washington County

An old deed may name a county that no longer exists, or a boundary that has since moved.

Jackson County was created in 1816 from Clark, Jefferson, and Washington counties when Indiana became a state. The county was named after Andrew Jackson. Over the following decades, Jackson County lost territory to the creation of Jennings, Scott, Bartholomew, Lawrence, and Brown counties.
