When Europeans reached the territory of present-day North Dakota in the mid-1700s, several peoples were already living in the region. The Mandan, Hidatsa, and Arikara were settled along the Missouri River; the Ojibwa (locally called Chippewa or Anishinaabe) and Cree resided in the northeast; and various Sioux groups (the Assiniboine, Yankton, Wahpeton, and Teton) inhabited areas in the north, South East, and west.
