Oceti Sakowin
A member of the Cheyenne River Sioux Tribe performing during the Grand Entry at the Cheyenne River Sioux Tribe Fair Rodeo and Powwow, Eagle Butte, South Dakota, September 4, 2016.
The Mandan, Sahnish (Arikara), Hidatsa, and Pawnee peoples allied with the U.S. military against the Oceti Sakowin for several strategic and historical reasons:
- Defense Against Traditional Foes: The Oceti Sakowin frequently raided these agricultural tribes, driving them to seek protection through alliances with the U.S. government.12
- Strategic Interests: Many village leaders recognized the United States as the emerging regional hegemon. They perceived that cooperating with the U.S. was the most effective strategy for retaining possession of their tribal lands.2
- Battle Honors: Serving as scouts for the U.S. military allowed men from these tribes to gain battle honors against their traditional enemies without violating the prohibitions against intertribal warfare established by the Treaty of Fort Laramie.2
- Survival: By adopting this strategy, these village groups suffered significantly fewer casualties during the Plains Wars than the nomadic tribes who resisted the U.S. military.2
