Series 2: Subject Files, Subseries 2: Tribal (1852-1994), the single largest body of material in the collection, documents the AAIA's relationship with more than 300 Native American communities and organizations from one end of the country to the other and the matters of uppermost concern to them. The AAIA's involvement in the lives of these entities varied widely in duration and intensity, sometimes precipitated by natural or man-made crises, sometimes engendered by long-term but equally invidious threats to tribal self-sufficiency. Many critical junctures in Native American history are chronicled in this subseries, from the Pueblo of Taos' struggle to recover its sacred Blue Lake to the Native Village of Point Hope's opposition to nuclear detonations; from the termination of Wisconsin's Menominee to the recognition of Florida's Miccosukee. Less prominent but, to the communities concerned, vitally important issues abound in these files, be it the location of a high school, the consolidation of two Indian agencies, the preservation of traditional fishing rights, or the encroachment of a hydroelectric project.
