American Indian Citizenship Day, also known as Native American Citizenship Day, is observed every June 2 in the United States. This day commemorates the Indian Citizenship Act of 1924, which granted U.S. citizenship to all Native Americans born in the country. Prior to this Act, Native Americans were not considered U.S. citizens and were excluded from the rights and privileges associated with citizenship. The observance acknowledges the historical struggles for citizenship rights, including the impact of treaties and court rulings that shaped Native American legal status. While not an official holiday, it is recognized by indigenous peoples, human rights organizations, and educational institutions. The day serves as a reminder of the ongoing challenges related to voting rights, as many states continued to deny Native Americans the right to vote even after the 1924 Act.
