Oceti Sakowin, or Seven Council Fires, refers to the seven major divisions among the Dakota people: Mdewakanton, Wahpekute
, Wahpeton, Sisseton (all Santee/Eastern Dakota), Yankton, Yanktonai (both Yankton/Nakota), and Lakota (Teton).
The Dakotas are composed of four bands: the Mdewakantons, Wahpekute
, Wahpetons, and Sissetons.
the four Santee tribes Mdewakanton, Wahpekute
, Wakpeton and the slightly divergent Sisseton, the Yankton-Yanktonai and the Teton, (geographically during the 19th century, the Eastern, Central and Western divisions) often called the "Seven Council Fires", a reference to the seven constituent tribes or sub-tribes of the people as a whole.
3) The information to be provided is based on the fundamental principles of social scientific inquiry, which includes both oral Eastern Dakota history, specifically the Dakota bloodlines of M'dewakantonwan, Wahpekute, Wahpetonwan, and Sissitonwan, as well as previous written documentation.
Further, I was able to locate written documentation at the Minnesota Historical Society about my late great-grandfather Anpetu Wisicu (John Sioux), cited in the 1853 M'dewakantonwan and Wahpekute Dakota Treaty Annuity Pay List.
Before outbreak of hostilities, Scandinavians seem to have had friendly contacts with the neighboring Mdewakanton, Wahpeton, Sisseton and Wahpekute
peoples, forming the eastern division of the Dakota (Sioux) nation.
