Who were at the first thenksgiving?

The first Thanksgiving is commonly believed to have taken place in 1621 between the Pilgrims, who had settled in Plymouth, Massachusetts, and the Wampanoag people. The Pilgrims celebrated their successful harvest with a three-day feast, which included around 50 Pilgrims and 90 Wampanoag guests. This gathering was a moment of cooperation and sharing between the two groups, although the relationship between them would later become strained.
