The Federal Acknowledgment Process (FAP) is one of the most important and contentious issues facing Native Americans today. A complicated system of criteria and procedures, the FAP is utilized by federal officials to determine whether a Native community qualifies for federal recognition by the United States government. In Forgotten Tribes, Mark Edwin Miller offers a balanced and detailed look at the origins, procedures, and assumptions governing the FAP. His work examines the FAP through the prism of four previously unrecognized tribal communities and their battles to gain indigenous rights under federal law. Based on a wealth of interviews and original research, Forgotten Tribes features the first in-depth history and overview of the FAP and sheds light on this controversial Native identification policy involving state power over Native peoples and tribal sovereignty. Mark Edwin Miller is an assistant professor of history at Southern Utah University.
