King Philip's War was an armed conflict in 1675–1676 between a group of indigenous peoples of the Northeastern Woodlands, the English New England Colonies and their indigenous allies. The war is named for Metacom, the Pokanoket chief and sachem of the Wampanoag who adopted the English name Philip because of the friendly relations between his father Massasoit and the Plymouth Colony. The war continued in the most northern reaches of New England until the signing of the Treaty of Casco Bay on April 12, 1678.
