After the arrival of the Mayflower on December 16, 1620, at Plymouth Harbor, the pilgrims settled in an abandoned Wampanoag village. It took a couple of months until the settlers had contact with the indigenous. The contact came with Tisquantum (Squanto), an Indian who helped the English in how to plant corn, fish and develop a subsistence economy, preventing them from starving. In March of 1621, the pilgrims entered in a treaty of mutual protection with the Pokanoket Wampanoag leader, Ousamequin (Massasoit).
