The Hidatsa are a Siouan people, a part of the Three Affiliated Tribes. The Hidatsa's autonym is Hiraacá. According to the tribal tradition, the word hiraacá derives from the word "willow"; however, the etymology is not transparent and the similarity to mirahací ‘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. What is now known as the Hidatsa tribe is the amalgamation of these three groups: the Hidatsa proper, the Awatixa, and the Awaxawi. These groups had discrete histories and spoke different dialects; they came together only after settling on the Missouri River. The Amahami have a creation tradition similar to that of the Mandan, which describes their emergence long ago from the Earth, at Devil's Lake. Later they moved westward to the Painted Woods and settled near a village of Mandan and another of Awatixa. Wikipedia [ - ]
