The Sioux are really made up of different groups with varying histories and customs. In studying the Sioux, the first challenge is to learn the various names and locations of the different bands.
Siouan was a widespread Indian language family. Tribes in many parts of North America spoke Siouan dialects. The tribal name Sioux, pronounced SUE, is applied only to a specific division of Siouan-speaking people, however. The name is derived from the French version of a CHIPPEWA (ojibway) word in the Algo-nquian language. The Chippewa tribe called their enemies Nadouessioux for “adders,” a kind of snake. The Sioux also are known collectively (especially in Canada) as the Dakota (pronounced da-KO-tah), from which has come the names of two U. S. states, North and South Dakota. In the Siouan language, Dakota (or Lakota or Nakota) means “allies.”
There were four ancestral branches of Sioux, with different bands in each. The largest branch was the Teton (or Titonwan), with the following bands: (1) Oglala; (2) Brule (Sicangu); (3) Hunkpapa; (4)Miniconjou; (5) Oohenonpa (Two Kettle); (6) Itazipco (Sans Arcs); and (7) Sihasapa.
A second branch was the Santee, with the following bands: (1) Sisseton; (2) Wahpeton: (3) Wahpekute; and (4) Mdewakanton. (The term Santee used historically more accurately applies to just the Wahpekute and Mdewakan-

Ton groups, not Sisseton and Wahpeton as well. In any case, all four are considered distinct dialect groups.)
A third branch was the Yankton (or Ihanktonwan), with only one band, the Yankton.
A fourth branch was the Yanktonai (or Ihankton-wanna), with the following bands: (1) Yanktonai; (2) Hunkpatina; and (3) Assiniboine. The ASSINIBOINE separated from their relatives and are discussed under their own entry.
The Teton use the Lakota version of the tribal name; the Santee say Dakota; and the Yankton and Yanktonai use Nakota.
The Teton, Yankton, Yanktonai, and four Santee groups also called themselves the Oceti Sakowin, or “Seven Council Fixes.”
The Sioux originally lived as Woodland Indians along the upper Mississippi River. It is known from early records of Jesuit explorers of the 1600s that the Sioux once dominated territory that now comprises the southern two-thirds of Minnesota, as well as nearby parts of Wisconsin, Iowa, North Dakota, and South Dakota. By the mid-1700s, some Sioux were migrating westward toward and across the Missouri River. The reason: Their traditional enemies, the Chippewa, were now armed with French guns, making warfare with them much more dangerous. Moreover, with the European demand for furs, game in the Sioux’s prairie country was becoming scarcer.
The Teton Lakota migrated the farthest west to the Black Hills region of what is now western South Dakota, eastern Wyoming, and eastern Montana. They sometimes also are called the Western Sioux. The Yankton Nakota settled along the Missouri River in what is now southeastern South Dakota, as well as in southwestern Minnesota and northwestern Iowa. The Yanktonai Nakota settled to their north along the Missouri in what is now eastern North and South Dakota. The Yankton and Yanktonai are sometimes referred to together as the Middle Sioux. The Santee Dakota stayed along the Minnesota River in what is now Minnesota. They therefore are referred to as the Eastern Sioux.
