Pontiac's War (1763-1766) was an armed conflict between a coalition of Native American tribes and British colonial forces in the Great Lakes region, the Ohio Country, and the upper Mississippi Valley following the conclusion of the Seven Years' War. The war is named after Pontiac, an Odawa war leader who became the most prominent figure associated with the uprising, though the conflict involved dozens of tribes acting with varying degrees of coordination. The war resulted in significant casualties on both sides, the destruction of several British frontier forts, and ultimately helped precipitate the Royal Proclamation of 1763, which attempted to restrict colonial settlement west of the Appalachian Mountains.
The conflict emerged from a convergence of material and political grievances. Following the British defeat of France in the Seven Years' War, France ceded its North American territories under the Treaty of Paris (10 February 1763). British commanders, particularly General Jeffrey Amherst, discontinued the French practice of providing gifts to tribal leaders - a custom that had served as a practical mechanism for maintaining alliances and trade relationships. At the same time, British settlers and soldiers occupied former French forts and expanded into territory tribes regarded as their own. Spiritual and political ferment among the tribes also played a role; the Delaware prophet Neolin preached a nativist message urging rejection of European goods and customs, which Pontiac and others incorporated into calls for resistance.
The war began in May 1763 with a coordinated assault on British forts across a broad front. Within weeks, tribal forces had captured or destroyed nine forts: Fort Sandusky, Fort St. Joseph, Fort Miami, Fort Ouiatenon, Fort Michilimackinac, Fort Edward Augustus, Fort Presque Isle, Fort Le Boeuf, and Fort Venango. The sieges of Fort Detroit and Fort Pitt, both strategically significant, failed to result in British surrender. At Fort Pitt, British forces under Captain Simeon Ecuyer distributed blankets from a smallpox hospital to tribal emissaries during the siege; the extent to which this constituted deliberate biological warfare and its epidemiological effect remain subjects of historical inquiry. The British counteroffensive, including Colonel Henry Bouquet's victory at the Battle of Bushy Run (5-6 August 1763), gradually reversed the tribal advance. Formal peace was not concluded until 1766, when Pontiac met with British Superintendent of Indian Affairs Sir William Johnson at Oswego.
The war had lasting consequences for British colonial policy. The Royal Proclamation of 1763, issued in October of that year, established a boundary along the Appalachian crest intended to separate colonial settlement from Native American territory. Colonial resistance to this restriction became a source of tension with the Crown and is sometimes cited among the accumulating grievances that preceded the American Revolution. The war also figures in debates about the nature of Native American political organization, the capacity for inter-tribal coordination, and the degree to which Pontiac exercised centralized command rather than serving as one prominent leader among several.

There is broad scholarly consensus on the basic chronology and principal engagements of the war. Contested areas - including Pontiac's actual leadership role, the intentionality of the Fort Pitt smallpox incident, and the relationship between the war and the Proclamation of 1763 - are addressed on the relevant debate and viewpoint pages.
