The document summarizes the origins of the Thanksgiving holiday in the United States. It describes how the Pilgrims arrived in America on the Mayflower in 1620 and had a difficult first winter, with half of them dying from illness. The following fall, they had their first successful harvest with the help of the native Wampanoag people, including Squanto who acted as an interpreter. To celebrate the harvest, the Pilgrims and Wampanoag shared an autumn feast that is now remembered as the first Thanksgiving.
