In what year did Native Americans gain U.S. citizenship?

Native Americans were granted U.S. citizenship in 1924 through the Indian Citizenship Act, also known as the Snyder Act. This landmark legislation was significant because it recognized Native Americans as citizens of the United States, enabling them to vote and enjoy the same rights and privileges as other American citizens, although many states found ways to deny them the right to vote for years afterwards. Prior to this act, Native Americans were often viewed as wards of the state and did not have full legal status. The passage of the Indian Citizenship Act marked a crucial step towards recognizing the rights of Native Americans within the U.S., although the fight for equality and recognition continued long after. The other options, while years of some notable events, do not pertain to the granting of citizenship to Native Americans.
