How did the federal government’s post–civil war policies in the west affect native americans?

The federal government policies after the Civil War in the West affected the Native Indians by taking away their land. Native Indians restricted to reservations, where they settled with small areas of land for their use. The West opened for the white settlers by providing land at a less price. Native Indians stopped to roam in plains, where the settlers started there life as ranchers and farmers.  The Dawes Act of 1887 made the Native Indians adopt the life of the American by teaching them to be farmers.
