Caddoan Mississippian culture

The Caddoan Mississippian culture was a prehistoric Native American culture considered by archaeologists as a variant of the Mississippian culture. The Caddoan Mississippians covered a large territory, including what is now Eastern Oklahoma, Western Arkansas, Northeast Texas, Southwest Missouri and Northwest Louisiana of the United States.

Archaeological evidence has established that the cultural continuity is unbroken from prehistory to the present. The speakers of Caddo and related Caddoan languages in prehistoric times and at first European contact have been proved to be the direct ancestors of the modern Caddo Nation of Oklahoma.
