How did whites finally overcome resistance of the Plains Indians, and what happened to the Indians after their resistance ceased?

The whites overcome the resistance of the Plains Indians by fighting wars and removing Indians from their land.

Explanation:

As the white settlers began to move in the Plains, they began to establish their farms and ranches. The Native Indians remain hostile to the situation because the whites were taking away the lands. The white killed animals, especially buffalo to weakened Indians as they hunted Buffalo for living. Several Indian battles fought between two sides. As the Indians lost wars, they forced to live in reservations. Many died on their way to reservations because of diseases, starvation and cold.
