The Indiana Legislature mandated Clay County in 1825, with territory partitioned from Owen, Putnam, Sullivan, and Vigo counties. Its name honors Henry Clay,[3] a famous antebellum American statesman. The first Courthouse was built in the newly platted town of Bowling Green in 1828 but moved to Brazil, Indiana in 1876.

The Wabash & Erie Canal through Clay County was built on the abandoned works of the Cross-Cut Canal that was to link the Wabash & Erie Canal at Terre Haute to the Central Canal at Point Commerce (Worthington). The Cross-Cut Canal was started in the mid 1830s but was abandoned when the financial crisis hit the United States in the late 1830s.
By 1849, it was decided that the Wabash and Erie was to be extended to Evansville Indiana via the abandoned works of the Cross-Cut and Central Canals.
