Explanation:

The Indian Appropriations Act was a logical extension of the peace program of the President Grant. The act called for the US government to avoid recognizing Plains Indians as an autonomous nation or tribe. The act then said Plains Indians should be regarded as individuals. Additionally, Congress believed that all Indians should be regarded as persons, and that the federal government should be legally named "wards".

This Act of 1851 provided money for placing Western tribes on settlements. The United States Government secured and enclosed reservations.
