Migration toward the Southwest
The Sioux were first noted historically in the Jesuit Relation of 1640, when they were living in what is now Minnesota. Their traditions indicate that they had moved there some time before from the northeast. They were noted in 1678 by the French explorer Daniel Duluth and in 1680 by Father Louis Hennepin in the Mille Lacs region in Minnesota. Their migration had been in a southwesterly direction in the face of the hostile Ojibwa, who had been equipped with guns by Europeans.
In the mid-18th cent., having driven the Cheyenne and Kiowa out of the Black Hills, the Sioux inhabited the N Great Plains and the western prairies—mainly in Wisconsin, Iowa, Minnesota, North and South Dakota, and up into the bordering provinces of Canada. They then numbered at least 30,000. The Tetons, numbering some 15,000, were the most populous of the seven tribes, and the Oglala Sioux, the largest group of the Teton, numbered some 3,000. The Sioux had a typical Plains-area culture, including buffalo hunting and the sun dance.
