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.
Shreveport was established in 1837 in the southern part of the parish, and in 1838, the Louisiana portion of the Caddo cession, formerly a part of Natchitoches Parish, became Caddo Parish. Because the Indian agent had been so diligent in his duties, the migration of settlers to the southwestern United States beginning after the Louisiana Purchase in 1803 was precluded in the area.
