And Phoenix, Arizona, has become the largest U.S. city to replace Columbus Day with Indigenous Peoples’ Day. Phoenix joins a growing list of cities including Denver, Seattle, Minneapolis and Albuquerque.

Columbus Day has long evoked sadness and anger among Native Americans, who object to honoring a man who opened the door to European colonization, the exploitation of native peoples and the slave trade.
