Answer:
The Oklahoma land rush of 1889 affected the Native American by allowing white settlers to settle in the nearly 2 million acres of unassigned land. By introducing the Dawes Severalty Act, the government began private land ownership for Natives, by putting them on smaller plots of land. Native Indians lost millions of acres and found themselves marginalized. With a lack of law enforcement in the new settlement, Natives often were targeted by the settlers who stole their cattle and farm tools.
