What was the main purpose of the reservation system?

The main purpose of the reservation system was to allocate specific areas of land for Native American tribes, often as a means of controlling their movement and preserving their way of life in the face of westward expansion by settlers. It aimed to isolate Indigenous peoples from the encroaching population and facilitate their assimilation into Euro-American culture. However, the system frequently resulted in the loss of traditional lands and resources, leading to significant cultural, social, and economic challenges for many tribes.
