Native American Nations / Caddoan Peoples

Caddoan Peoples

The languages spoken by Caddoan Peoples are Caddo, Kitsai, Wichita, Pawnee, and Arikara. Just prior to the Lewis and Clark Expedition, Caddoan-speaking nations had inhabited the plains from southeastern Texas to North Dakota. For more on the Caddo Nation, see Freeman-Custis Expedition.
