Absaroka
Absaroka is a historical region that was proposed in the 1930s, encompassing parts of present-day Montana, South Dakota, North Dakota, and Wyoming. The name "Absaroka" is derived from the Crow Native American tribe, who referred to themselves as "Apsáalooke." The idea of Absaroka was primarily a political movement advocating for statehood, but it never materialized.
The concept of Absaroka gained some popularity during the Great Depression, as residents sought greater autonomy and economic relief. Although the movement faded, it remains a notable example of regional identity and the desire for self-governance in American history.
