Indigenous Peoples’ Day is a holiday in the United States that celebrates and honors Indigenous 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. It began as a counter-celebration on the same day as the U.S. federal holiday of Columbus Day, which honors Italian explorer Christopher Columbus. Many people do not observe Columbus Day at all, citing the lasting harm Indigenous tribes suffered because of Columbus’s contributions to the European colonization of the Americas.
October 14, 2019, was the first official Indigenous Peoples’ Day in Vermont. The bill made Vermont one of the first states to legally rename Columbus Day, following the example of New Mexico, Maine, Alaska, North Carolina, Minnesota, and South Dakota (where the second Monday in October is called Native American Day).
