The Hidatsas also called Fat Belly Missouri or Minnetarees (Where Minnetaris) are a Native American tribe originally from North Dakota. They were allies of the Mandans, with whom they grouped within the Mandan Nation, Hidatsa and Arikara.
The Mandans are a Native American people who historically lived on the shores of the Missouri and two of its tributaries, the Heart River and the Knife River, in present-day North Dakota and South Dakota. Speakers of Mandan, a Siouan language, the Mandans whose particularity was to have created permanent villages were distinguished from other tribes of the Great Plains region who led a nomadic existence by following the herds of bison.
These permanent settlements were made up of round dwellings, mud huts surrounding a central plaza. While buffalo hunting was originally the mainstay of the Mandan's daily life, the resources it provided were later supplemented by agriculture and trade.
