What was the conflict between the Cheyenne and Arapaho tribes and white settlers known as?

The conflict between the Cheyenne and Arapaho tribes and white settlers is known as the Cheyenne-Arapaho War. This series of clashes primarily took place during the 1860s and was a response to increasing encroachment by settlers and miners into traditional tribal territories, particularly in Colorado. The war was marked by incidents such as the Sand Creek Massacre in 1864, where a peaceful encampment of Cheyenne and Arapaho was attacked by Colorado militia, leading to significant loss of life and escalating tensions between the tribes and settlers.

While terms like "The Plains Wars" encompass a broader range of conflicts involving various Native American tribes on the Great Plains, the Cheyenne-Arapaho War specifically highlights the distinct and direct confrontations between these two tribes and European settlers. Other options, such as "The Colorado Rebellion" and "The Wyoming Uprising," refer to different historical events or uprisings that occurred in other contexts and locations, focusing on different groups or set of circumstances unrelated to the direct conflicts between the Cheyenne, Arapaho, and settlers.
