Kiowa are the Native American tribe, the indigenous people of the Great Plains. Kiowa calls themselves Ka'igwu or Gaigwu, which means "Principal People". Kiowa were patrilineal with the principalities that lived in a semi-sedentary structure. They were engaged in hunting and gathering, which means that they did not live long enough in one place to deal with land and crops. They migrated together with the American Bison, which was the main source of food, along with antelopes, deer, forest fruits, wild fruits, turkeys and other game. In the late 1600s they migrated south to modern-day Wyoming and South Dakota.
