See it on the History map →What happened
Napoleon rose fast as an artillery officer and general in the revolutionary wars, took power in a 1799 coup and crowned himself emperor in 1804. His armies beat Austria, Prussia and Russia, and by 1810 he dominated Europe from Spain to Poland. His Civil Code of 1804 replaced feudal law with equality before the law and secure property rights. The 1812 invasion of Russia destroyed his army. Defeated in 1814, he escaped exile and lost finally at Waterloo in 1815.
Why it matters
He spread revolutionary law, swept away old states and redrew Europe's map. The Napoleonic Wars killed an estimated 3 to 6 million people. His Civil Code still underlies law in France and dozens of countries.
Legacy and how we know
His vast correspondence, tens of thousands of letters now published, military records, the Civil Code itself, memoirs by his officers and enemies, and his own memoirs dictated in exile on St Helena.
Still debated
Historians still argue whether he preserved the Revolution's gains or betrayed them: a modernizer, or a dictator who restored slavery and ruled through war.
Connections (5)
▸French Revolution brought to power Napoleon BonaparteWell documented
The connection
The Revolution swept away the old aristocratic officer corps, opened promotion to talent, and fought wars that needed generals. Napoleon, a minor Corsican noble, rose from captain to general between 1793 and 1796. When the weak Directory government faced crisis, he seized power in the coup of 18 Brumaire, November 1799, promising order.
When and how
France and Italy, 1793 to 1799: the siege of Toulon (1793), the Italian campaign (1796 to 1797), and the coup in Paris on November 9, 1799.
How we know
Military records, government documents of the coup, and accounts by participants such as his brother Lucien, who helped carry it out.
Debates and open questions
Did Napoleon end the Revolution or complete it? He kept legal equality but crushed political liberty; historians have argued this since the 1800s.
▸Napoleon Bonaparte triggered, by invading Spain, the Latin American wars of independenceWell documented
The connection
In 1808 Napoleon forced Spain's king to give up the throne and installed his brother Joseph. With no legitimate king, colonial elites formed local councils, called juntas, to rule in the captive king's name, and these soon became independence movements. Portugal's royal family fled to Brazil, paving the way for its later separation.
When and how
Bayonne, France, May 1808, where Spain's Charles IV and Ferdinand VII were made to renounce the crown; juntas formed in Caracas, Buenos Aires and elsewhere in 1809 to 1810.
How we know
Junta proclamations, which cite the king's captivity, Spanish and colonial records, and letters of leaders like Bolívar.
Debates and open questions
Would independence have come anyway? Many historians think creole frustration with Spain made it likely, and that Napoleon mainly decided the timing.
▸Napoleon Bonaparte redrew Germany, setting the stage for Unification of GermanyMostly agreed
The connection
Napoleon forced the end of the centuries-old Holy Roman Empire in 1806 and merged roughly 300 German territories into a few dozen larger states. His occupation also stirred German national feeling against French rule. After his fall, the 1815 Congress of Vienna kept a simpler map of 39 states, most of which Prussia later united.
When and how
German lands, 1803–1815: the 1803 reorganization, the Confederation of the Rhine (1806), Prussia's defeat at Jena (1806) and the 'Wars of Liberation' (1813–14).
How sure are we?
Treaties and maps of the period show the consolidation clearly; Johann Gottlieb Fichte's Addresses to the German Nation (1808) shows rising nationalism.
Debates and open questions
How widely ordinary Germans felt national loyalty in 1813, rather than local or dynastic loyalty, is debated; later nationalist historians may have exaggerated it.
▸Napoleon Bonaparte failed to crush the Haitian RevolutionWell documented
The connection
In 1802 Napoleon sent tens of thousands of troops under his brother-in-law Charles Leclerc to retake Saint-Domingue, and he restored slavery in Guadeloupe. Toussaint Louverture was seized and died in a French prison. Yellow fever and fierce resistance led by Dessalines destroyed the army; France withdrew in 1803, and Napoleon sold Louisiana to the US.
When and how
Saint-Domingue, 1802 to 1803; Leclerc died of yellow fever, and the final French defeat came at Vertières in November 1803.
How we know
French military dispatches, Leclerc's letters to Napoleon describing the losses, and Toussaint's memoir written in prison at Fort de Joux.
Debates and open questions
Did Napoleon plan to restore slavery in Saint-Domingue? His secret instructions to Leclerc are ambiguous, though his actions in Guadeloupe suggest he did.
▸Tsarist Russia and the Russian Empire defeated the 1812 invasion of Napoleon BonaparteWell documented
The connection
Napoleon invaded Russia in June 1812 with roughly 600,000 men to force Tsar Alexander I back into his trade blockade of Britain. The Russians retreated, fought at Borodino and abandoned Moscow, which burned. With no surrender and winter coming, the French retreated; cold, hunger, disease and Cossack attacks destroyed the army. Perhaps 100,000 or fewer escaped; estimates vary.
When and how
Russia, June–December 1812; Napoleon's Grande Armée, Tsar Alexander I and General Mikhail Kutuzov; Battle of Borodino, September 7.
How we know
Army records, letters and memoirs from both sides, and Charles Minard's famous 1869 chart showing the army shrinking on its march.
Debates and open questions
Who set Moscow on fire, Russian patriots under Governor Rostopchin or chance, is debated; so are the army's real size and losses.
