Most of the Caddo historically lived in the Piney Woods ecoregion of the United States, divided among the state regions of East Texas, southern Arkansas, western Louisiana, and southeastern Oklahoma. This region extends up to the foothills of the Ozarks.
In 1859, the U.S. Government moved the Caddo of Louisiana from its Brazos reservation in Texas to what would eventually become Canadian County, Oklahoma. Showetat, the last hereditary chief of the Caddos set up his camp near the present Union City, and is considered Canadian County's first permanent resident.
