A strict hand was held by Massachusetts over the Narragansetts and other subject tribes, contracting their limits by repeated cessions, not always entirely voluntary. The Wampanoags, within the jurisdiction of Plymouth, experienced similar treatment. By successive sales of parts of their territory, they were now shut up, as it were, in the necks or peninsulas formed by the northern and eastern branches of Narragansett Bay, the same territory now constituting the continental eastern portion of Rhode Island. Though always at peace with the colonists, the Wampanoags had not always escaped suspicion. The increase of the settlements around them, and the progressive curtailment of their limits, aroused their jealousy. They were galled, also, by the feudal superiority, similar to that of Massachusetts over her dependent tribes, claimed by Plymouth on the strength of certain alleged former submissions. None felt this assumption more keenly than Pometacom, head chief of the Wampanoags, better known among the colonists as King Philip of Mount Hope, nephew and successor of that Massasoit, who had welcomed the Pilgrims to Plymouth. Suspected of hostile designs, he had been compelled to deliver up his fire-arms and to enter into certain stipulations. These stipulations he was accused of not fulfilling; and nothing but the interposition of the Massachusetts magistrates, to whom Philip appealed, prevented Plymouth from making war upon him. He was sentenced instead to pay a heavy fine and to acknowledge the unconditional supremacy of that colony.
