What is a short-summary of Part IV in the nonfiction book, The Heartbeat of Wounded Knee?

In Part IV, Treuer takes the reader through the conservative reaction against the New Deal in the 1950s. The policy initiatives of the era, in part religiously motivated, resulted in the termination of federal wardship status and transfer of oversight responsibility to the states. Treuer follows Indian migration to the cities as the government pursues a policy of relocation.
