Are the Sioux Indians part of the great plains?

The term "Sioux" refers to a large group of related tribes, some of whom belonged to the Plains culture, while others did not.

The Sioux tribes are grouped into three divisions according to the dialect they speak:

• the eastern Sioux or Dakotas
• the central Sioux or Nakotas
• the western Sioux or Lakotas (also called Teton Sioux)

It is the western or Teton Sioux that belonged to the Plains culture, living on the Great Plains and entirely dependent on horses for hunting, growing no crops of any kind.

The Teton Sioux tribes are:

1. Oglala
2. Brule
3. Minneconjou
4. Two Kettles
5. Hunkpapa
6. Sans Arc
7. Blackfoot Sioux

The Blackfoot Sioux (who today live on the Cheyenne River and Standing Rock reservations in South Dakota) have no connection at all with the Blackfoot tribe.
