Sioux - Modern Geographic Divisions

Modern Geographic Divisions

The Sioux maintain many separate tribal governments scattered across several reservations and communities in North America: in the Dakotas, Minnesota, Nebraska, and Montana in the United States; and in Manitoba, southern Saskatchewan and Alberta in Canada.

The earliest known European record of the Sioux identified them in Minnesota, Iowa, and Wisconsin. After the introduction of the horse in the early 18th century, the Sioux dominated larger areas of land—from present day Central Canada to the Platte River, from Minnesota to the Yellowstone River, including the Powder River country.
