In the 1880s the government decided that reservations only encouraged Indians to live as part of a tribe, rather than as individuals. Getting rid of reservations would free up land for settlers, reduce costs and force Indians to assimilate.
The Dawes Act (1887)
The Dawes Act was like a Homestead Act for Plains Indians.
Each Indian family was given a 160-acre plot of reservation land
Single people got 80 acres and orphans 40 acres
Plains Indians who accepted and left their reservation could become American citizens
All the reservation land left over was sold to whites (e.g. in Oklahoma)
The Dawes Act is significant because it made life for Plains Indians even harder. The small, poor quality plots made farming very difficult – many gave up and sold their land to whites
In 1890 the Indian Frontier officially ceased to exist, and the first national park was created (Yosemite) to protect the little areas of wilderness that remained.
