History
Formed in 1813 from Knox County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Warrick County was created by Indiana Territory from Knox County on April 1, 1813. The county lost territory to the creation of Perry and Posey counties in 1814, then became part of the new state of Indiana in 1816. Over the following decades, Warrick's boundaries were repeatedly adjusted through gains and losses to neighboring counties including Gibson, Spencer, Vanderburgh, and Pike.
