Sioux Tribe/Nation
The Sioux, or Oceti Sakowin (Seven Council Fires), are a large confederation of Siouan-speaking peoples whose territory spanned the Northern Great Plains from Minnesota to the Rocky Mountains. The confederation includes three major divisions: the Dakota (Santee), Nakota (Yankton-Yanktonai), and Lakota (Teton). The Sioux were among the most significant Indigenous powers encountered during and after the Lewis and Clark Expedition, with the Teton Lakota famously confronting the expedition at the confluence of the Bad and Missouri rivers in 1804. Multiple Sioux bands entered into treaties with the United States at Portage des Sioux and other locations in the 1810s–1820s.
