The Spirit Lake Nation's name in the Santee Dakota language is "Mni Wakan Oyate" (also transcribed "Mniwakaƞ Oyate"). The nation was formerly called the Devils Lake Sioux Tribe in various English-language materials. It is comprised of the Pabaksa (Iháŋkthuŋwaŋna), Sisseton (Sisíthuŋwaŋ) and Wahpeton (Waȟpéthuŋwaŋ) bands of the Dakota people. The Spirit Lake Dakota Reservation shares geography with eastern North Dakota, beside Devils Lake. Fort Totten is the capital of this sovereign nation.
