In 1621, the chief of the Wampanoag tribe and the governor of Plymouth agreed to a truce. And that fall, their respective people actually did gather to celebrate a successful harvest. George Washington University professor David J. Silverman joins host Krys Boyd to talk about how the peace finally dissolved – and about how we should look at the time period through the eyes of the indigenous people involved. His new book is called “This Land Is Their Land: The Wampanoag Indians, Plymouth Colony, and the Troubled History of Thanksgiving.”
