Why do we celebrate and the history of Thanksgiving Day?
The event that Americans commonly call the “First Thanksgiving” was celebrated by the Pilgrims after their first harvest in the New World in October 1621. This feast lasted three days, and—as accounted by attendee Edward Winslow—it was attended by 90 Native Americans and 53 Pilgrims.
In 1621, the Plymouth colonists and Wampanoag Indians shared an autumn harvest feast that is acknowledged today as one of the first Thanksgiving celebrations in the colonies. For more than two centuries, days of thanksgiving were celebrated by individual colonies and states.
