The French and Indian War (1754–1763) was a theater of the Seven Years' War, which pitted the North American colonies of the British Empire against those of the French, each side being supported by various Native American tribes. At the start of the war, the French colonies had a population of roughly 60,000 settlers, compared with 2 million in the British colonies. The outnumbered French particularly depended on their native allies.

Two years into the French and Indian War, in 1756, Great Britain declared war on France, beginning the worldwide Seven Years' War. Many view the French and Indian War as being merely the American theater of this conflict; however, in the United States the French and Indian War is viewed as a singular conflict which was not associated with any European war. French Canadians call it the guerre de la Conquête ('War of the Conquest').

The British were victorious in the Montreal Campaign in which the French ceded Canada in accordance with the Treaty of Paris (1763). France also ceded its territory east of the Mississippi to Great Britain, as well as French Louisiana west of the Mississippi River to its ally Spain in compensation for Spain's loss to Britain of Spanish Florida. (Spain had ceded Florida to Britain in exchange for the return of Havana, Cuba.) France's colonial presence north of the Caribbean was reduced to the islands of Saint Pierre and Miquelon, confirming Great Britain's position as the dominant colonial power in northern America.
