Metacomet (1638–1676), also known as Metacom and by his adopted English name King Philip, was a Wampanoag and the second son of the sachem Massasoit. He became a chief of his people in 1662 when his brother Wamsutta (or King Alexander) died shortly after their father Massasoit. Wamsutta's widow Weetamoo (d. 1676), sunksqua of the Pocasset, was Metacomet's ally and friend for the rest of her life. Metacomet married Weetamoo's younger sister Wootonekanuske. No one knows how many children they had or what happened to them all. Wootonekanuske and one of their sons were sold to slavery in the West Indies following the defeat of the Native Americans in what became known as King Philip's War.
At the beginning Metacom sought to live in harmony with the colonists. As a sachem, he took the lead in much of his tribes' trade with the colonies. He adopted the European name of Philip, and bought his clothes in Boston, Massachusetts.
But the colonies continued to expand. To the west, the Iroquois Confederation also was fighting against neighboring tribes in the Beaver Wars, pushing them from the west and encroaching on his territory. Finally, in 1671, the colonial leaders of the Plymouth Colony forced major concessions from him. Metacomet surrendered much of his tribe's armament and ammunition, and agreed that they were subject to English law. The encroachment continued until hostilities broke out in 1675. Metacomet led the opponents of the English, with the goal of stopping Puritan expansion.
In the spring of 1660 Metacomet's brother Wamsutta appeared before the court of Plymouth to request that he and his brother be given English names. The court agreed and Wamsutta had his name changed to Alexander, and Metacomet's was changed to Philip. Author Nathaniel Philbrick has suggested that the Wampanoag may have taken action at the urging of Wamsutta's interpreter, the Christian convert John Sassamon. Metacomet was later called "King Philip" by the English.
