The Indian Citizenship Act of 1924, also known as the Snyder Act, was proposed by Representative Homer P. Snyder (R) of New York and granted full U.S. citizenship to America's indigenous peoples, called "Indians" in this Act. While the Fourteenth Amendment to the United States Constitution defined as citizens any person born in the U.S., the amendment had been interpreted to restrict the citizenship rights of most Native people. The act was signed into law by President Calvin Coolidge on June 2, 1924. It was enacted partially in recognition of the thousands of Indians who served in the armed forces during World War I.
