This part of Texas gets a good annual rainfall and has many rivers, creeks, swamps and lakes. The Hasinais Caddo lived and farmed in small clearings in the pine forest. Most of the Hasinais farms and villages are near flowing creeks or springs with fresh water. They farmed because farming was the best way to get food. There were no big herds of buffalo or other animals to hunt.
Farmers have larger and denser populations.
The Caddo formed confederations to protect and defend themselves from other tribes with their large numbers. They were friendly with most of the tribes to the west and south of them. To the north the Osage Indians were enemies. They also traded goods all over Texas, the Mississippi river valley and the southeastern United States. The Kadohadache Caddo were probably a paramount chiefdom with one big chief over many subchiefs.
