Answer: False.
Explanation: After the Civil war, Settlement from the East transformed the Great Plains. The huge herds of American bison that roamed the plains were virtually wiped out, and farmers plowed the natural grasses to plant wheat and other crops. The cattle industry rose in importance as the railroad provided a practical means for getting the cattle to market.
The loss of the bison and growth of white settlement drastically affected the lives of the Native Americans living in the West. In the conflicts that resulted, the American Indians, despite occasional victories, seemed doomed to defeat by the greater numbers of settlers and the military force of the U.S. government. By the 1880s, most American Indians had been confined to reservations, often in areas of the West that appeared least desirable to white settlers.
