Why were the Plains Indians displaced, and what were the consequences of this displacement?

The Plains Indians faced displacement primarily due to the westward expansion of American settlers and the U.S. government's policies. As settlers moved into the Great Plains, they began to claim lands traditionally used by the Plains Indians. The U.S. government often negotiated treaties, designating specific lands or reservations for the tribes. However, many of these treaties were broken or renegotiated under less favourable terms. The displacement disrupted the traditional way of life of the Plains Indians, as they were forced onto reservations with limited resources. The near extinction of the buffalo, due to overhunting by settlers, further impacted their survival. Conflicts also arose, leading to battles and massacres, marking a tragic chapter in U.S.-Native American relations.
