Columbus Day is a U.S. holiday celebrated on October 13, commemorating Christopher Columbus's landing in the Americas. However, the holiday has become controversial due to Columbus's actions against Native Americans, leading many regions, including parts of California, New York, Minnesota, and Colorado, to rename it Indigenous People's Day. This shift aims to honor Native American culture and history rather than celebrate Columbus's legacy. Observers are encouraged to educate themselves about Native American culture on this day. The holiday's transformation reflects a growing awareness of historical injustices and a desire to promote a more inclusive narrative of American history.
