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.
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.
