Maine is joining a handful of states that have renamed Columbus Day to honor Native Americans.
Democratic Gov. Janet Mills said Friday that "there is power in a name and who we choose to honor" before signing a law that drops the state's recognition of the federal holiday.
The October holiday will now be called Indigenous Peoples' Day in Maine.
A small but growing number of states, including New Mexico and Vermont, have moved to swap celebrating explorer Christopher Columbus for a tribute to Native Americans.
Demands to do away with Columbus Day date to the 1970s. Native American tribes are pressing for the change, pointing to atrocities they suffered.
Critics say that suppressing history could lead to repeating it.
