During the Seven Years' War, the American colonies played a significant role as a theater of conflict between Britain and France, known in North America as the French and Indian War. The war, fought from 1756 to 1763, arose from territorial disputes in North America and involved colonial militias alongside regular British troops. The American colonies contributed both manpower and resources to the British war effort. The war's conclusion with British victory in 1763 expanded British territorial claims in North America but also strained relations with the colonies. The subsequent imposition of taxes to cover war debts would eventually lead to growing colonial dissent and the American Revolutionary War.
