By 1500, or even earlier, American Indians of North Dakota had organized into tribes, or groups of people who have a common heritage. The people of an Indian tribe share a culture or a way of life that includes language, traditions, and religion. A tribe’s oral traditions, or storytelling, help the people understand their common history and traditions. Culture makes each tribe different from all other tribes. Each tribe also identified a particular area of land where they lived and hunted.
Today there are six tribes with headquarters in North Dakota. They are the Mandan, Hidatsa, Arikara, Lakota Sioux, Dakota Sioux, and Turtle Mountain Chippewa. The Lakota, Dakota, and Chippewa are related to other bands of their tribes that live in other states.
