Caddo
The Caddo Nation is a confederacy of several Southeastern Native American tribes, who traditionally inhabited much of what is now East Texas, northern Louisiana and portions of southern Arkansas and Oklahoma. Today the Caddo Nation of Oklahoma is a single federally recognized tribe with its capital at Binger, Oklahoma. The different Caddo languages have converged into a single language.
