United States of America, on the map of history

What was United States of America before it was United States of America? Below, every era of this land in the Maps of History collection — who ruled it, what it was called, and when control changed — each line linked to the dated map that shows it. Modern borders stand in as an honest approximation; every atlas says so on the map itself.

United States (the Thirteen Colonies) · The Age of Revolutions, 1775–1848

The age’s opening act and standing exhibit: the republic that proved independence possible (1783), doubled itself with Louisiana thanks to Haiti’s victory (1803), survived a rematch with Britain (1812–15), and declared the hemisphere closed (1823). Its constitution traveled everywhere its cotton did — and its half-million enslaved people had become two million by 1848: the age’s greatest promise and greatest evasion in one flag.

The United States · The American Civil War, 1861–1865

The belligerent. One nation on this map and two at war inside it: 22 million people, nine-tenths of the industry and the navy against an 11-state Confederacy founded, in its own documents, to perpetuate slavery. Four years and roughly 750,000 dead settled two questions forever — the Union is indivisible, and no person in it is property — and deferred a third, the content of Black citizenship, for a century. The zones painted over this single map shape are the whole story: charcoal Confederacy, tan border belt, and the grey-tan of Union control spreading along coasts and rivers until nothing else remains.

United States of America · The Great War, 1914–1918

Neutral and profiting until the U-boat and the Zimmermann telegram made neutrality untenable (Ch. 6, 8); at war from April 1917 “to make the world safe for democracy.” Its credit saved the Entente before its 2-million-man army decided 1918 (Ch. 10). Wilson then designed the peace’s architecture — and the Senate declined to inhabit it: the world’s new strongest power went home.

United States of America · The War Room — WW2, 1936–1945

Neutral arsenal, then (after Pearl Harbor) the alliance’s engine: two-ocean navy, strategic bombing, D-Day, the bomb — and 40% of the world’s war production. Emerged as superpower with its homeland untouched, wrote the postwar order, and has led it since.

United States of America · The Cold War, 1945–1991

The other superpower — the only combatant of 1945 to emerge richer, and the architect of the Western order: Marshall money, NATO, Bretton Woods, the bomb. It fought the era by proxy and paid at home in red scares, a broken presidency, and 58,000 names on a wall in Washington. It ended the era as the last superpower standing — a position, this atlas suggests, that is a situation to be managed, not a verdict.
