The Caddo culture is a Native American heritage primarily found in the southeastern United States, particularly in areas that are now Texas, Louisiana, Arkansas, and Oklahoma. The Caddo people are known for their advanced agricultural practices, including the cultivation of crops like corn, beans, and squash. They built large earthen mounds for ceremonial and residential purposes, reflecting their complex social structure and spiritual beliefs. Caddo society was organized into various tribes, each with its own leadership and customs. They engaged in trade with neighboring tribes and European settlers, exchanging goods such as pottery, textiles, and food. The Caddo language belongs to the Caddoan family, and their rich oral traditions preserve their history and cultural identity.
