Three Affiliated Tribes (Mandan, Hidatsa, and Arikara Nation)
Name	Three Affiliated Tribes (Mandan, Hidatsa, and Arikara Nation)
Location	Fort Berthold Indian Reservation, North Dakota

Three Affiliated Tribes (Mandan, Hidatsa, and Arikara Nation) are an Indigenous confederation of the Mandan people, Hidatsa people, and Arikara people primarily located on the Fort Berthold Indian Reservation in North Dakota. The confederation traces alliances, shared settlements, and intermarriage among the three Nations, and engages with federal institutions such as the Bureau of Indian Affairs and national movements including the Native American Rights Fund and the National Congress of American Indians. Their history intersects with events like the Lewis and Clark Expedition, the Dakota War of 1862, and policies enacted under the Indian Reorganization Act.

History

The ancestral narratives of the Mandan people, Hidatsa people, and Arikara people recount migrations across the Great Plains and riverine adaptations along the Missouri River and its tributaries, leading to sedentary village life exemplified by earthlodges documented by explorers such as Lewis and Clark Expedition and ethnographers like George Catlin. Contact with European and American actors introduced trade with the Hudson's Bay Company and the American Fur Company, and exposure to smallpox epidemics reshaped demographics following episodes connected to figures like Sakakawea (also spelled Sacagawea). Treaty-making with the United States—including accords influenced by negotiators like William Clark—altered territorial holdings, culminating in reservation consolidation at Fort Berthold Indian Reservation. Resistance and adaptation involved leaders and advocates engaging with institutions such as the Indian Rights Association and later legal challenges in venues like the United States Court of Claims.

Government and Sovereignty

The tribal government operates under a constitution and elected tribal council that interacts with the Bureau of Indian Affairs and pursues claims through bodies such as the Indian Claims Commission and litigants like the Three Affiliated Tribes of the Fort Berthold Reservation v. United States decisions. The Nation engages with federal statutes including the Indian Self-Determination and Education Assistance Act and interfaces with state entities like the State of North Dakota on jurisdictional matters involving law enforcement agencies such as county sheriffs and agreements with the Federal Bureau of Investigation. Sovereignty assertions are pursued through collaborations with organizations like the National Congress of American Indians and representation in national forums including the United Nations Permanent Forum on Indigenous Issues.

Culture and Society

Cultural life centers on ceremonial cycles, powwows, and practices maintained by tribal entities including cultural committees and museums like the Fort Berthold Museum. Traditional arts encompass hidatsa and mandan pottery forms recorded by collectors such as Edward S. Curtis, while social structures reflect clan systems and kinship documented by anthropologists like Morris Opler and Franz Boas. Ceremonial leaders and elders work with educational institutions such as Mandan, Hidatsa and Arikara (MHA) Head Start programs and cultural revitalization projects linked to archives at the Library of Congress and collaborations with universities including North Dakota State University and University of North Dakota. Public events reference historical figures like Sakakawea and commemorate episodes involving the Black Hills migrations and Plains intertribal diplomacy.

Economy and Natural Resources

Economic life has included agriculture, buffalo hunting traditions, and commercial enterprises such as tribal energy ventures interacting with companies like Enbridge and regional markets serviced by the Williston Basin. The discovery and extraction of oil and gas on reservation lands, especially after technological changes related to hydraulic fracturing and operators from firms headquartered near Bismarck, North Dakota, transformed revenues and regulatory interactions with the Environmental Protection Agency and the Indian Minerals Development Act. The Nation manages fisheries and wildlife resources in cooperation with agencies like the U.S. Fish and Wildlife Service and participates in regional economic development via organizations such as the Tribal Business Information Center.

Reservation and Land

The Fort Berthold Indian Reservation spans portions of McLean County, North Dakota, McKenzie County, North Dakota, and McLean County, North Dakota—noting overlaps in county boundaries—and encompasses communities including New Town, North Dakota and historic village sites near the Missouri River and Lake Sakakawea. Land tenure was dramatically altered by federal projects such as the Garrison Dam and the subsequent creation of Lake Sakakawea, which produced inundation, displacement, and legal claims addressed in forums like the Indian Claims Commission and negotiated agreements with the U.S. Army Corps of Engineers. Contemporary land management includes zoning, trust land status administered by the Bureau of Indian Affairs, and land consolidation efforts involving programs like the Land Buy-Back Program for Tribal Nations.

Language and Education

Languages include varieties of Mandan language, Hidatsa language, and Arikara language (also called Sahnish), all of which face challenges of language shift documented in studies by scholars such as Dell Hymes and institutions like the Endangered Language Alliance. Revitalization efforts involve immersion schools, curriculum development with partners such as Sealaska Heritage Institute models, and grant-funded programs under acts like the Native American Languages Act. Educational institutions serving the Nation include local schools within the Fort Berthold Reservation, tribal colleges and state universities such as United Tribes Technical College and collaborative programs with North Dakota State University and University of North Dakota.

Notable People and Contemporary Issues

Prominent individuals associated with the Nations include cultural figures and leaders who have engaged with national debates, ranging from traditional elder advocates connected to Sakakawea commemorations to contemporary politicians and activists who have worked with organizations like the Native American Rights Fund and movements addressing environmental justice such as opposition to pipeline projects including Keystone XL and protests coordinated with groups like Standing Rock Sioux Tribe demonstrators. Contemporary issues include litigation over mineral rights adjudicated in courts such as the United States Court of Appeals for the Federal Circuit, public health initiatives responding to concerns raised by Centers for Disease Control and Prevention collaborations, and economic diversification through enterprises listed with the Bureau of Indian Affairs and regional partners in Bismarck, North Dakota.
