Crow people

The Crow, whose autonym is Apsáalooke ([ə̀ˈpsáːɾòːɡè]), are Native Americans living primarily in southern Montana. Today, the Crow people have a federally recognized tribe, the Crow Tribe of Montana, with an Indian reservation, the Crow Indian Reservation, located in the south-central part of the state.

Sioux

The Sioux or Oceti Sakowin (, SOO; Dakota/Lakota: Očhéthi Šakówiŋ [oˈtʃʰeːtʰi ʃaˈkoːwĩ]) are groups of Native American tribes and First Nations people from the Great Plains of North America. The Sioux have two major linguistic divisions: the Dakota and Lakota peoples (translation: 'friend, ally' referring to the alliances between the bands).
