The
Great Sioux Nation was the political structure of the
Sioux at the time of their contact with Europeans and Euro-Americans. Most of the peoples speaking a
Siouan language were members of the
Očhéthi Šakówiŋ (pronounced [oˈtʃʰetʰi ʃaˈkowĩ]) or
Seven Fires Council. The Seven members are sometimes grouped into three regional/dialect groups (Lakota, Western Dakota, and Eastern Dakota), but these mid-level identities were not politically institutionalized: the seven smaller groups were separate members of one
confederacy.
