Atsina Indians
The Atsina Indians, possibly named from the Blackfoot term meaning “gut people,” are an Algonquian-speaking tribe historically located along the Milk River in Montana and extending into Canada. They were associated with the Arapaho and had various names reflecting their identity, including “fall people” and “belly men.” The Atsina faced significant challenges over the years, including alliances and conflicts with tribes such as the Blackfeet and Crow. Their population has fluctuated from an estimated 3,000 in 1780 to around 586 by 1923, indicating ongoing struggles through the years.
