Teton Tribe
The Teton, or Lakota, are the westernmost and largest division of the Oceti Sakowin (Great Sioux Nation), comprising seven bands including the Oglala, Brulé, Hunkpapa, and Miniconjou. Their territory encompassed the western Great Plains from the Missouri River to the Black Hills and beyond. The Teton Lakota had one of the most significant encounters with the Lewis and Clark Expedition in September 1804, when a tense standoff occurred near the mouth of the Bad River. They entered into subsequent treaties with the United States, though they remained one of the most independent and militarily powerful nations on the Northern Plains throughout the 19th century.
