The term "Caddoan" refers to a group of Native American tribes that historically inhabited the Great Plains and southeastern regions of the United States. This cultural group includes tribes such as the Caddo, Wichita, and Pawnee. They are known for their agricultural practices, particularly the cultivation of crops like corn, beans, and squash. Caddoan societies were organized into complex chiefdoms and had rich spiritual beliefs and traditions. They constructed distinctive dwellings, often made of grass and mud, and engaged in trade with neighboring tribes. The Caddoan languages belong to the Caddoan language family, which includes several distinct languages spoken by these tribes.
