It began as a day of giving thanks and sacrifice for the blessing of the harvest and of the preceding year. You may wonder who was the person that started Thanksgiving. In 1621, the Plymouth colonists and the Wampanoag shared an autumn harvest feast that is acknowledged today as one of the first Thanksgiving celebrations in the colonies. I usually eat turkey; some people eat ham, turkey, and have a bunch of sides!
