Thanksgiving Day is a national holiday that is based on the 1621 Plymouth colonist and the Wampanoag people sharing an autumn harvest feast that subsequently became the first Thanksgiving celebration in the colonies. For the Native Americans, the assembly of the Wampanoag people and English settlers had more to do with political alliances, diplomacy, and a pursuit of peace. While Americans share a meal and give thanks for family, friends, and community, the United American Indians of New England recognize it as a National Day of Mourning for Native Americans and their allies.
