<human>: Can you tell me about the origin of Thanksgiving?
<bot>: Thanksgiving is a holiday that originated in 1621 when the Pilgrims and the Wampanoag Native Americans celebrated together. The Pilgrims had fled from religious persecution in England, while the Wampanoag people were living in what is now Massachusetts. They shared food and stories around a large fire, which was later dubbed as a "Thanksgiving Feast." In modern times, Thanksgiving has become an American tradition to give thanks for the blessings in one's life.
