Johnson County Was Organized in 1854 from Three Older Counties
The county was organized in 1854. Its first county seat was Wardville, then Buchanan. When Hood County split off in 1867, Cleburne became the permanent county seat. The county was named after Middleton Tate Johnson, a Texas Ranger and soldier.
Population grew quickly in the railroad era. The county had about 700 residents at founding, over 33,000 by 1900. It surpassed 150,000 by the 2010s as DFW suburbs expanded south. For full history, visit the TSHA Handbook of Texas entry.
