America and Britain: From Mother Country to Special Relationship

The empire America rebelled against became, in time, its closest ally — a reversal that took two wars and two centuries.

The United States exists because it broke from Britain, and yet no two nations of the modern era have ended up closer. The relationship runs from the colonial rule the colonies rejected, through two wars between them, to the alliance that anchored the twentieth-century world. It is the rare case of an enemy becoming a best friend — and the friendship is all the more durable for how hard-won it was.

This guide traces that arc in order: the colonial break, the Revolution, the second war of 1812, the long cooling into partnership, and the wartime alliance that produced NATO and the "special relationship." Each entry links to a full account.

From Rivals to Partners

Across the nineteenth century the former enemies slowly became friends. These entries trace the shift from rivalry to a working partnership built on shared interests and a common language.

Britain's former rival France took a parallel road from enemy to ally — see America and France — and the wars that bind this story run through every U.S. war and major conflict.
