In the 1750s, the conflicting ambitions of three great empires—
France,
Great Britain, and the
Iroquois League—crashed together in the backcountry of Pennsylvania. In
the resulting war, fought between 1755 and 1760, the future of the North American continent was largely determined.
Superior organization and strategy allowed France and its Indian allies to dominate the first two years of the war. But William Pitt, named British secretary of state in 1757, then increased Britain's financial commitment to the war, giving British soldiers and their American colonial allies the resources they needed to defeat the French in battle by 1760. In the
Treaty of Paris, signed in 1762, a vanquished France
surrendered Canada and all territorial claims east of the Mississippi River to Britain. Britain also won control of Florida, ceded by Spain (a French ally).
Flush with success, British policymakers came to believe that
their control over the North American continent was firmly established. But Native Americans who had fought in the war in alliance with Britain believed that they had won the right to
territories west of the Appalachians, while American colonists soon objected to
British postwar policies aimed at consolidating their hold on North America.
As a result, while the French and Indian War removed one great power from the contest over America, it did not truly end the dispute over control of the Pennsylvania backcountry, nor did it guarantee Britain's control over the continent. In fact, tensions between Britain and its American colonists that grew out of the war and its aftermath led, in just a few short years, to
the American Revolution.
