When did pilgrims have there feast?

The Pilgrims held their first Thanksgiving feast in the autumn of 1621, after their successful harvest. This three-day celebration included 50 Pilgrims and around 90 Native Americans, primarily from the Wampanoag tribe. The event was a way to give thanks for the harvest and the assistance they received from the Native Americans in their survival. It is often considered the foundation of the modern Thanksgiving holiday in the United States.
