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.
The Caddo Prairie Indian Agency was located here from 1825 until 1831, and the last Native American village in Caddo was located about 10 miles west of here. In 1835, the United States purchased about 1 million acres from the Caddo Indians for $80,000 dollars, paying $30,000 dollars in goods at the agreement signing and $10,000 cash each of the next five years.
