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.[4] This feast lasted three days, and—as accounted by attendee Edward Winslow[5]—it was attended by 90 Native Americans and 53 Pilgrims.[6] The New England colonists were accustomed to regularly celebrating "thanksgivings"—days of prayer thanking God for blessings such as military victory or the end of a drought.[7]
