The Mayflower made landfall at Plymouth in late 1620. In March of the following year, they met Tisquantum, the man they called Squanto.
Tisquantum proved indispensible to Plymouth Colony, as he often negotiated for them with tribal leaders and taught them how to utilize native resources. In fact, he negotiated a treaty between the Wampanoag and the English that stated neither would harm the other.
Unfortunately, he was accused by the Wampanoag of using his position for his own gain. The Wampanoag chieftains demanded his execution, but settlers balked at handing him over. Ultimately, in November of 1622, Tisquantum fell ill with fever and died.
He bequeathed his possessions to his English friends at Plymouth, but more importantly, the peace treaty he negotiated endured for a half century.
