What Indian tribe celebrated with the Plymouth Colonists during thanksgiving?

Thanksgiving Day is a harvest festival celebrated primarily in the United States and Canada. Traditionally, it has been a time to give thanks for a bountiful harvest. While there was an underlying religious element in the original celebration, Thanksgiving today is primarily identified as a secular holiday.[1]

Although earlier feasts are known to have taken place, Thanksgiving as it is known and celebrated today derives from a joint celebration between the Pilgrim settlers of Plymouth, Massachusetts and members of the Native American Patuxet tribe of the Wampanoag people in 1621.

In Canada, Thanksgiving Day is celebrated on the second Monday in October, which is Columbus Day in the United States. In the United States, it falls on the fourth Thursday of November.
