Fort Reno began as a temporary camp in July 1874 near the Darlington Agency, which needed protection from an Indian uprising that eventually led to the Red River War. After the conflict ended, the post remained to control and protect the Southern Cheyenne and Southern Arapaho reservation, and Fort Reno was established as a permanent fort on July 15, 1874. Soldiers from Fort Reno also attempted to control Boomer and Sooner activity during the rush to open the Unassigned Lands for settlement. Among the units stationed here were the famed Ninth Cavalry of Buffalo Soldiers. The fort lent its name to the city of El Reno, which still exists, as well as Reno City, which was abandoned before Oklahoma statehood.
