History
Formed in 1819 from Barren County and Hardin County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Hart County was created on April 1, 1819 from Barren and Hardin counties. In 1825, Hart County lost territory to the creation of Edmonson County, and over the following decades exchanged small boundary adjustments with Barren, Metcalfe, and Larue counties.
