King Philip's War (1675-1678) was an armed conflict in colonial New England between an alliance of Native American nations and the English colonies of Plymouth, Massachusetts Bay, Connecticut, and Rhode Island. It is named for Metacomet, also known as King Philip, the Wampanoag sachem widely regarded as the principal leader of the Native alliance. The war is considered one of the deadliest conflicts, proportional to population, in American history, and its causes, conduct, and legacy remain subjects of historical interpretation. For background on the colonial and Native societies involved, see Massachusetts Bay Colony and Narragansett.

Historians broadly agree on the war's major events: its outbreak near Swansea, Plymouth Colony, in June 1675; the involvement of the Wampanoag, Narragansett, Nipmuc, and Pocumtuck peoples on one side and the United Colonies of New England on the other; the December 1675 Great Swamp Fight against the Narragansett; and Metacomet's death in August 1676, after which organized resistance largely collapsed in southern New England, though fighting continued longer in Maine and New Hampshire. Beyond this factual core, interpretation diverges considerably regarding the war's underlying causes, the proportionality and conduct of colonial military actions, the legal and moral status of Native land claims, and the war's long-term effects on Native sovereignty and population in the region. A fuller account of the conflict's background and course is provided at king-philips-war-history.

• Land encroachment and sovereignty viewpoint - Emphasizes ongoing colonial expansion onto Native lands, the erosion of Wampanoag political autonomy, and English assertions of jurisdiction over Native peoples as the war's primary drivers. See king-philips-war-land-encroachment-viewpoint.
• Cultural and religious conflict viewpoint - Frames the war substantially as a clash between English Puritan religious and legal norms and Native customary practices, including disputes over the prosecution of Native individuals under colonial law. See king-philips-war-cultural-conflict-viewpoint.
• Inevitable-conflict viewpoint - Holds that demographic pressure from English population growth made large-scale conflict with Native nations likely regardless of specific triggering incidents. See king-philips-war-inevitability-viewpoint.
• Contingent-causation viewpoint - Argues the war resulted from a specific, avoidable chain of events-particularly the killing of John Sassamon and the colonial response to it-rather than broad structural inevitability. See king-philips-war-contingency-viewpoint.
• Colonial defense viewpoint - Characterizes English military actions as defensive responses to Native attacks on settlements, emphasizing colonist casualties and destroyed towns. See king-philips-war-colonial-defense-viewpoint.
• Disproportionate-violence viewpoint - Holds that colonial forces, including allied Native nations, engaged in violence against noncombatants exceeding military necessity, citing events such as the Great Swamp Fight. See king-philips-war-disproportionate-violence-viewpoint.

• The Great Swamp Fight of December 1675, in which colonial forces attacked a Narragansett winter encampment containing noncombatants, remains disputed regarding its classification as a military engagement versus a massacre. See king-philips-war-great-swamp-fight-controversy.
• The post-war treatment of Native captives, including the sale of some into slavery in the Caribbean and elsewhere, is a documented point of historical dispute regarding scale and intent. See king-philips-war-captive-treatment-controversy.
