The French and Indian War (1754–1763) is the name for the North American theater of the Seven Years' War. The war was fought primarily between the colonies of Great Britain and New France, with both sides supported by military troops from Europe. In 1756, the war erupted into the world-wide conflict involving Britain and France. In Canada, some historians refer to the conflict as simply the Seven Years' War, although French Canadians often call it La guerre de la Conquête ("The War of Conquest"). In Europe, there is no specific name for the North American part of the war. The name refers to the two main enemies of the British colonists: the royal French forces and the various Native American forces allied with them, although Great Britain also had Native allies.

The war was fought primarily along the frontiers separating New France from the British colonies from Virginia to Nova Scotia, and began with a dispute over the confluence of the Allegheny and Monongahela rivers, the site of present-day Pittsburgh, Pennsylvania. The dispute erupted into violence in the Battle of Jumonville Glen in May 1754, during which Virginia militiamen under the command of George Washington ambushed a French patrol. British operations in 1755, 1756 and 1757 in the frontier areas of Pennsylvania and New York all failed, due to a combination of poor management, internal divisions, and effective French and Indian offense. The 1755 capture of Fort Beauséjour on the border separating Nova Scotia from Acadia was followed by a British policy of deportation of its French inhabitants, to which there was some resistance.
