The city was named after the 7th governor of Kansas, George T. Anthony who was in office at the time. Following the reorganization of Harper County in 1878 following the original fraudulent organization in 1873, Anthony was designated the temporary county seat, as Bluff City, designated county seat of the fraudulent county organization, did not exist at the time. In 1879, a county seat election was held, and Anthony won over Harper City even though 2,960 ballots were cast with 800 legal voters in the county.
