How do you know the oklahoma land rush of 1889 affected the native americans

Native Americans were removed from their traditional lands to make way for white settlement was relocated. The relocations began in 1817, and by the 1880s, Indian Territory (Oklahoma) was a new home to a variety of tribes, including the Chickasaw, Choctaw, Cherokee, Creek, Cheyenne, Commanche, and Apache.

In 1889 President Harrison made the first of a long series of authorizations that eventually removed most of Indian Territory from Indian control in Oklahoma.

The Dawes Severalty Act (1887) allowed whites to settle large parts of land that had previously been designated to Indian tribes.

In short the Indians were twice removed from lands. One before settlers came and another after the government gave them territory.
