The Oceti Sakowin Oyate (People of Seven Council Fires, known to some as the Sioux Nation) are linguistically related peoples who speak three different dialects — Dakota , Nakota , and Lakota —of the same language. The traditional names of the Oceti Sakowin Oyate groups are: Wahpekute , Wahpetunwan , Sisistunwan , Bdwakantunwan , Ihanktunwan, Ihanktunwanna , and Titunwan . Today, there are many Oceti Sakowin nations descended from the original groups who maintain their own lands, governments, courts, and various government programs. They are located in Minnesota, Nebraska, South Dakota, North Dakota, and Montana in the United States, and Saskatchewan and Manitoba in Canada.
