Answer:
Indian Appropriation Act is the name given to acts which were passed throughout the 19th and 20th century. Lots of acts were passed under the same name. The most notable landmark under these acts was the Appropriation Bill for Indian Affairs of 1851 and also the 1871 Indian Appropriation Act. The acts made it easier for the government to take away the lands of Plain Indians, it meant that the Indians won't be able to form treaties. It was a continuation of President Grant's Peace Policy. The acts declared that the US government would not treat the Plain Indians as the Independent Nation, instead, they would be treated as wards of the state.
