The Pilgrims arrived at Plymouth Plantation in 1620 after a difficult journey from England on the Mayflower. The first winter was devastating, with half of the Pilgrims dying due to the harsh conditions. In the spring of 1621, a Native American named Squanto taught the Pilgrims how to survive by showing them how to plant corn, tap maple trees, and identifying edible plants. That fall, the Pilgrims had a successful harvest and celebrated with the Native Americans, including Squanto and the chief Massasoit. Today, Thanksgiving is celebrated on the fourth Thursday of November as a national holiday where people give thanks and share a meal of traditional foods from that first harvest.
