The framework of bounded, 'reserved' lands to which the United States confined Indigenous nations through treaties and federal power. Built as an instrument of dispossession, control, and forced assimilation, it cleared land for settlers and tried to dissolve Native nations through allotment, boarding schools, and agency rule. Yet the same reserved lands and the treaties that created them became the territorial and legal ground on which tribal sovereignty survived. Reservations are not relics: they are the living jurisdictions of self-governing Native nations today.
The word at the center of this system is 'reserved.' When a nation signed a treaty ceding most of its homeland, the land it kept was the part it reserved to itself. That small grammatical fact carries a large legal weight. It means many reservations are not land the government generously gave to a tribe. They are land the tribe never surrendered. The United States built the reservation system to shrink Native nations, confine them, and assimilate them out of existence. It did enormous damage. But because those reserved lands were held under treaties, and treaties are law, the cage the government built also became the ground on which sovereignty endured. The nations the system was meant to erase govern themselves on that ground still.
