Why did the reservation system fail

:)

Explanation: First, white settlers needed more and more land, and the fact that tribes were treated as separate nations with separate citizens made it more difficult to take land from them and "assimilate" them into the general population. Assimilation had become the new ideal. The goal was to absorb the tribes into the European-American culture and make Native people more like mainstream Americans.

2. Second, the House of Representatives was angry that they did not have a voice in these policies. Under the Constitution, treaties are ratified by the U.S. Senate, not the House, even though the House has to appropriate the money to pay for them. So Congress passed a compromise bill in 1871 that, in effect, brought an end to the treaty system. The bill contained the following language buried in an appropriations law for the Yankton Indians.
