Step-by-step explanation:
Federal Indian policy builds the connection between the United States Government and the Indian Societies inside its boundaries. The Constitution provides the central government primitive loyalty for administering with tribes.

By stating that the administration would no longer sign agreements with Indian tribes, Congress efficiently dispatched the lingering trails of the Native Americans' national freedom.
