History

Formed in 1793 from Nelson County

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

Hardin County was created from Nelson County on February 20, 1793, and named after John Hardin. The county lost territory over time: Ohio County was created from Hardin in 1799, followed by Breckinridge in 1800, Green in 1804, Grayson in 1810, Hart in 1819, Meade in 1824, and Larue in 1843.
