Citizenship in 1924: A Law and Its Limits

On June 2, 1924, President Calvin Coolidge signed the Indian Citizenship Act, also known as the Snyder Act. With a single stroke of a pen, the federal government declared that all Native Americans born within the territorial limits of the United States were officially American citizens. At first glance, this seemed like a sweeping moment of inclusion. Yet behind the new law lay a tangled history of conflicting motives, complex legal boundaries, and significant gaps between federal promises and lived reality.

Before 1924, Native American citizenship was piecemeal and conditional. Under the original U.S. Constitution, Indigenous peoples were generally considered members of separate sovereign nations rather than citizens of the United States. Over the decades, Congress and federal courts created various pathways to citizenship, but these often required Native people to give up their cultural ties or tribal lands. For instance, the Dawes Act of 1887 offered citizenship to individuals who accepted divided parcels of reservation land and adopted Western agricultural lifestyles, a policy intended to assimilate Native people into white American society. Additionally, thousands of Native men gained citizenship by serving in the U.S. military during World War I. Even so, by the early 1920s, roughly one-third of all Native Americans remained legally classified as non-citizens on their own ancestral homelands.
