 The Lakota, or Western Teton/Tituwan Sioux, consisting of the Oglala, Mniconjou, Sicangu, Sihasapa, Oohenunpa, Hunkpapa, and Itazipco, traditionally ranged from lands east of the Missouri River valley to the Rocky Mountains.A common history and language, a strong respect for the land and nature, the common use of Pipestone and the reverence held for the stone, and ceremonies such as the Sun Dance, Sweat lodge, and Vision Quest, bind these peoples together.The name 'Brule' comes from the French word "brûlé" (burnt), the name French fur traders used for the "Sicangu" in the late 17th century.
