Indian history in the 20th century is about the battle for political sovereignty. In 1933 John Collier was appointed by Roosevelt to be commissioner of Indian affairs. He embraced the idea that all cultures make sense, work well, and serve the needs of the people in them. ‘Political sovereignty and economic autonomy’ looks at the efforts made by Collier on behalf of the Indians including the Indian Reorganization Act of 1934, the effect of World War and the termination policy that followed, and other schemes of assimilation. There are today at least 324 unacknowledged Indian communities in the United States, scattered throughout the country. Many of them are still seeking acknowledgement.
