The Crow are also called the Apsáalooke, Absaroka, and Apsaroke. Their name was given them by the Hidatsa, and meant “people [or children] of the large-beaked bird.” Historically, they lived in the Yellowstone River Valley. A Siouan tribe, they once were part of the Hidatsa, living around the headwaters of the upper Mississippi River in northern Minnesota and Wisconsin. Later, the Crow moved to the Devil’s Lake region of North Dakota, before splitting with the Hidatsa and moving westward.
Settling in Montana, the tribe split once again into two divisions, called the Mountain Crow and the River Crow. They were first encountered by two Frenchmen in 1743 near the present-day town of Hardin, Montana. When the Lewis and Clark expedition came upon them in 1804, they estimated some 350 lodges with about 3,500 members.
