History

Formed in 1857 from Cooke County and Jack County

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

Clay County was created on December 24, 1857, from Cooke and Jack counties, though it was not fully organized at first. The county was temporarily attached to other counties for judicial purposes several times during the 1860s, then was fully organized in 1860 before being disorganized in 1863 due to Indian attacks and settlers fleeing the area. Clay County was fully organized again in 1873 and went on to serve as the judicial seat for a large surrounding area of counties that had not yet been organized.
