 Several other California cities, including Richmond, Santa Cruz, and Sebastopol, now celebrate Indigenous Peoples' Day and encourage people to donate to a neighboring tribe and recognize the trauma and pain indigenous peoples have been subjected to by colonizers.At least thirteen states do not celebrate Columbus Day (Alaska, Hawaii, Iowa, Louisiana, Maine, Michigan, New Mexico, North Carolina, Oregon, South Dakota, Vermont, Washington, DC; Wisconsin); South Dakota officially celebrates Native American Day instead.Various tribal governments in Oklahoma designate the day as "Native American Day", or have renamed the day after their own tribes.
