As of the 2020 census, the community had 809 residents. A post office was established March 29, 1892 after the Sac and Fox land run of 1891. However, when a rail line built by the St. Louis and Oklahoma City Railroad was crossed by the line of the Eastern Oklahoma Railway in 1901, the town coalesced around that intersection, and was formally incorporated in 1906. Roads were not neglected; the town managed to get the Ozark Trail Highway through the location in 1916, and this road became the path of U.S. Route 66 through town in 1926.
