Indigenous Peoples’ Day is a holiday that celebrates and honors Native American peoples and commemorates their histories and cultures. It is celebrated across the United States on the second Monday in October, and is an official city and state holiday in various localities, including California. It began as a counter celebration held on the same day as the U.S. federal holiday of Columbus Day which honors Italian explorer Christopher Columbus. Many reject celebrating him, saying that he represents “the violent history of the colonization in the Western Hemisphere”, and that Columbus Day is a sanitation or covering-up of Christopher Columbus’ actions such as enslaving Native Americans.
