Many cities and states are observing the day. Here’s some of the history behind it.

Three years after President Biden became the first U.S. president to formally commemorate Indigenous Peoples’ Day, more than a dozen states recognize some version of the holiday in lieu of Columbus Day.

More than 100 cities have adopted the holiday, choosing to heed calls from Indigenous groups and other activists not to celebrate Christopher Columbus, the Italian navigator after whom the holiday is named. They say he brought genocide and colonization to communities that had been in the Americas for thousands of years. Many around the country, however, still celebrate Columbus Day or Italian Heritage Day as a point of pride.
