The Napoleonic Wars
From an obscure officer to master of Europe and back to a lonely island — the rise and fall of Napoleon, every milestone sourced.
A timeline of the Napoleonic Wars, from Napoleon Bonaparte's rise in the wars of the Revolution to his death in exile in 1821. It runs through the Italian and Egyptian campaigns, his coronation as emperor and the Napoleonic Code, the naval catastrophe of Trafalgar and the triumph of Austerlitz, the defeat of Prussia and the Continental System, the draining Peninsular War, the disastrous invasion of Russia, the final defeats at Leipzig and Waterloo, and the peace forged at the Congress of Vienna. Every event is backed by content-verified sources from scholarly references.

The Italian and Egyptian Campaigns
Napoleon first made his name in the wars of the Revolution. His lightning Italian campaign of 1796–97 shattered the Austrians and turned the young general into a national hero. In 1798 he sailed for Egypt, winning the Battle of the Pyramids against the Mamluks — but the venture unravelled when Admiral Nelson destroyed the French fleet at the Battle of the Nile, stranding the army. Napoleon slipped back to France to seize power.
Why it matters: These campaigns built the Napoleon legend and gave him the fame and prestige he used to overthrow the Directory. The Egyptian expedition also carried scholars whose work — including the discovery of the Rosetta Stone — helped found Egyptology.

The Rise of Napoleon
A brilliant young artillery officer from Corsica, Napoleon Bonaparte rose to fame through victories in the wars of the French Revolution, especially his Italian campaign. In November 1799, in the coup of 18 Brumaire, he overthrew the ruling Directory and made himself First Consul — effectively the ruler of France.
Why it matters: The coup of Brumaire ended a decade of revolutionary turmoil and concentrated power in one man's hands, opening the era that would bear his name and reshape the map of Europe.

Emperor of the French and the Napoleonic Code
In 1804 Napoleon crowned himself Emperor of the French in Notre-Dame, famously taking the crown from the Pope's hands to place it on his own head. That same year he promulgated the Napoleonic Code, a sweeping reform of civil law guaranteeing equality before the law, property rights, and secular authority.
Why it matters: The Napoleonic Code outlasted the empire and became the model for legal systems across Europe, Latin America, and beyond — arguably Napoleon's most enduring legacy, far more than any battlefield victory.

The Battle of Trafalgar
Off Cape Trafalgar in Spain, the British fleet under Admiral Horatio Nelson, aboard HMS Victory, annihilated the combined French and Spanish fleets without losing a single ship. Nelson was mortally wounded in the hour of his greatest triumph, dying as victory was won.
Why it matters: Trafalgar secured British command of the seas for a century and ended Napoleon's hopes of invading Britain. Master of the Continent, he would never master the ocean.

The Battle of Austerlitz
In his greatest victory, Napoleon lured the combined Austrian and Russian armies into a trap at Austerlitz — the 'Battle of the Three Emperors.' Feigning weakness, he split the allied line and shattered it, inflicting a crushing defeat that knocked Austria out of the war.
Why it matters: Austerlitz is often called the most perfect battle of Napoleon's career and the height of his military genius. It confirmed France as the dominant power on the European continent.

Jena-Auerstedt and the Fall of Prussia
When Prussia belatedly went to war, Napoleon destroyed its vaunted army in a single day. In twin battles fought on 14 October 1806 at Jena and Auerstedt, the French routed the Prussians and days later marched in triumph into Berlin. The kingdom that prided itself on the legacy of Frederick the Great was brought to its knees.
Why it matters: Jena-Auerstedt left Napoleon master of Germany and humiliated Prussia so thoroughly that it launched sweeping military and social reforms — reforms that would help forge the army that returned to beat him at Waterloo.

The Continental System
Unable to defeat Britain at sea after Trafalgar, Napoleon tried to strangle it economically. His Berlin Decree of 1806 launched the Continental System, a sweeping embargo meant to close all of Europe's ports to British trade. Enforcing the blockade across an entire continent proved impossible, and it hurt Europe's own economies as much as Britain's.
Why it matters: The Continental System became one of Napoleon's costliest miscalculations. Enforcing it drew him into the ruinous Peninsular War in Spain and, when Russia broke ranks and reopened trade with Britain, into the catastrophic invasion of 1812.

The Peninsular War
Napoleon's attempt to control Spain and Portugal ignited a brutal war on the Iberian Peninsula. Spanish and Portuguese guerrillas — a word born in this conflict — and a British army under the future Duke of Wellington bled the French armies for years in what Napoleon himself called his 'Spanish ulcer.'
Why it matters: The Peninsular War tied down and drained hundreds of thousands of French troops for years, sapping the empire's strength and giving Wellington the experience he would later use to defeat Napoleon at Waterloo.

The Invasion of Russia
Napoleon led the largest army Europe had ever seen — over half a million men of his Grande Armée — into Russia. The Russians retreated, burning everything behind them, and though Napoleon reached a devastated, abandoned Moscow, he was forced into a catastrophic winter retreat. Only a fraction of his army survived.
Why it matters: The Russian catastrophe destroyed the Grande Armée and shattered the myth of Napoleon's invincibility. It emboldened his enemies across Europe to rise against him and marked the beginning of his end.

The Battle of Leipzig and the First Abdication
A grand coalition of Russia, Prussia, Austria, and others turned on the weakened emperor. At the Battle of Leipzig in 1813 — the 'Battle of the Nations,' the largest battle in Europe before the First World War — Napoleon was decisively beaten. The allies invaded France, took Paris, and in April 1814 forced Napoleon to abdicate and exiled him to the island of Elba.
Why it matters: Leipzig broke French power in Germany, and the first abdication seemed to end the Napoleonic era. But Napoleon was not finished — and neither was the war.

The Congress of Vienna
With Napoleon exiled to Elba, the victorious powers gathered in Vienna from September 1814 to redraw the map of Europe. Chaired by the Austrian statesman Klemens von Metternich, and joined by Britain's Castlereagh, Russia's Tsar Alexander I, and France's Talleyrand, the Congress restored monarchies, reduced France to its old borders, and rebalanced the great powers so none could dominate the others. Napoleon's sudden return in 1815 interrupted but did not undo its work.
Why it matters: The Vienna settlement created the 'Concert of Europe,' a balance-of-power order that spared the continent a general war among the great powers for a generation. It set the pattern for European diplomacy through the nineteenth century.

The Hundred Days and Waterloo
Escaping Elba in 1815, Napoleon returned to France and reclaimed power for a period known as the Hundred Days. The allies mobilized against him one last time. On 18 June 1815, at Waterloo in Belgium, the armies of Wellington and the Prussian Blücher combined to defeat him decisively, ending his reign for good.
Why it matters: Waterloo brought the Napoleonic Wars to a final close and became a byword for total, definitive defeat. It ushered in a century of relative peace among the great powers of Europe.

Exile and Death on St Helena
This time the victors took no chances. Napoleon was exiled to St Helena, a tiny, remote island in the South Atlantic, where he lived out his final years under British guard and dictated his memoirs. He died there in 1821, at the age of 51.
Why it matters: Napoleon's death closed one of history's most extraordinary careers. In little more than two decades he had risen from obscure officer to master of Europe and fallen to a lonely prisoner — leaving behind reshaped nations, modern legal codes, and an enduring legend.
