The traditional homelands of the Caddo stretched from the Red River Valley in Louisiana to the Brazos River Valley in Texas. The Caddo were agricultural people whose culture emerged about 800 CE. Caddo culture is considered to be related to the Mississippian mound-building cultures.
The Caddo were an agricultural tribe living in what is now Louisiana and Texas when the first European explorers entered the region. The Caddo were a group of theocratic chiefdoms who were the cultural descendants of the earlier Mississippian mound-building cultures.
