Napoleon redrew Europe by cannon; the tricolor then sailed it around Africa and Asia. France built two empires: the first, Napoleon's, conquered the continent in a decade; the second, colonial, stitched a tricolor belt across Africa and Southeast Asia. Both ended in the same lesson — that empires built on glory are mortgaged to it.
The empire in images
The rise
The first empire began on 2 December 1804, when Napoleon Bonaparte crowned himself emperor in Notre-Dame — taking the crown from the pope's hands, as the story goes, to show he owed it to no one. Within a year came Austerlitz, the masterpiece battle that shattered two empires at once. By 1811 Napoleon ruled or dominated nearly all of Europe: 130 départements, satellite kingdoms for his brothers, and the Napoleonic Code imposed from Madrid to Warsaw.
The second empire rose from the ashes of the first. In 1830 France seized Algiers — then the seat of the Ottoman regency that had governed the coast since 1516 — beginning the conquest of its territories, the land that would become Algeria entering French colonial rule from 1830 to 1962; under the Second Empire and the Third Republic, the tricolor spread across West and North Africa, Indochina, and Madagascar. The ideology was the mission civilisatrice — the civilizing mission — and the method was the gunboat, the railway, and the colonial administrator.
The zenith
Napoleon's zenith was 1811–1812: a continental system strangling British trade, a Grand Empire from Spain to Poland, and Paris as the capital of the world. Then came Russia. The invasion of 1812 — 600,000 men marching into the largest country on earth — ended in frozen catastrophe: barely 30,000 returned. It was the beginning of the end, and everyone in Europe could see it.
The colonial zenith came a century later. In the 1920s the French colonial empire covered some 11.5 million square kilometers — the second largest on earth — with 110 million subjects from Dakar to Saigon. The 1931 Colonial Exhibition in Paris celebrated it as eternal; schoolchildren learned “nos ancêtres les Gaulois” from Algiers to Hanoi. It looked permanent. It was not.
The fall
The first empire fell at Waterloo on 18 June 1815, and Napoleon died a prisoner on St. Helena — the eagle caged on a rock in the South Atlantic. The second empire fell more slowly and more bloodily. In 1954 Dien Bien Phu destroyed a French army in Indochina, and the Geneva Accords ended the war; Vietnam, Laos, and Cambodia became independent.
Algeria was the wound that would not close. Eight years of war (1954–1962) — torture, terror, a million dead by Algerian counts — ended with the Evian Accords and Algerian independence in 1962, and nearly brought down the French Republic itself. The last major pieces followed: most of sub-Saharan Africa in 1960, Djibouti in 1977, Vanuatu in 1980. The tricolor came down, and stayed down.
The legacy
The empire's deepest legacy is a language and a legal system. Some 300 million people speak French across five continents; the Napoleonic Code underpins the law of dozens of countries; and laïcité, the French model of secularism, still shapes debates from Paris to Dakar. The Francophonie — 88 member states — is the empire's afterlife as a club.
The colonial empire also left France its most unresolved arguments: the memory of Algeria, the banlieues built for post-colonial immigration, the question of what the republic owes its former subjects. The empire ended; the argument about it never did.
Napoleon sold Louisiana in 1803 to fund his wars — America doubled in size, France got 80 million francs, and both sides have been arguing about who got the better deal ever since.
