Who were the pilgrims of Thanksgiving?

The Pilgrims of Thanksgiving were a group of English settlers who established the Plymouth Colony in present-day Massachusetts in the early 17th century. They were seeking religious freedom and left England aboard the Mayflower in 1620. The first Thanksgiving in 1621 was a harvest celebration shared with the Wampanoag people, who helped them survive their first year in the New World. This event is often regarded as the foundation of the modern Thanksgiving holiday in the United States.
