The Hidatsa (called Minnetaree by their allies, the Mandan) are a Siouan people, a part of the Three Affiliated Tribes. The Hidatsa's autonym is Hiraaca. According to the tribal tradition, the word hiraaca derives from the word "willow"; however, the etymology is not transparent and the similarity to mirahaci _willows_ inconclusive. The present name Hidatsa was formerly borne by one of the three tribal villages. When the villages consolidated, the name was adopted for the tribe as a whole. Their language is related to that of the Crow, and they are sometimes considered a parent tribe to the modern Crow in Montana. Occasionally they have also been confused with the Gros Ventres in Montana. Accounts of recorded history in the early 18th century identify three closely related village groups to which the term Hidatsa is applied.
