Background

The Napoleonic Wars were rooted in the political and social upheavals of the French Revolution (1789–1799), which led to the rise of Napoleon Bonaparte as First Consul and later Emperor of France. The revolutionary ideals of liberty, equality, and fraternity challenged the traditional monarchies of Europe, leading to widespread conflict.

Major Coalitions and Campaigns

War of the Third Coalition (1805)

In 1805, Britain, Austria, Russia, and Sweden formed the Third Coalition against France. Napoleon achieved a decisive victory at the Battle of Austerlitz on December 2, 1805, leading to the Treaty of Pressburg and the dissolution of the Holy Roman Empire.

War of the Fourth Coalition (1806–1807)

The Fourth Coalition, comprising Prussia, Russia, Saxony, Sweden, and Britain, faced Napoleon's forces in 1806. Napoleon's victories at the Battles of Jena and Auerstädt led to the occupation of Berlin. The subsequent Treaty of Tilsit in 1807 resulted in significant territorial losses for Prussia and the establishment of the Duchy of Warsaw.

Peninsular War (1808–1814)

In 1808, Napoleon's intervention in Spain and Portugal sparked the Peninsular War. The conflict saw the rise of guerrilla warfare and significant British involvement under Sir Arthur Wellesley (later the Duke of Wellington). The war drained French resources and contributed to Napoleon's eventual downfall.

Invasion of Russia (1812)

In 1812, Napoleon launched a massive invasion of Russia, aiming to compel Tsar Alexander I to comply with the Continental System. The campaign was disastrous for the French, with the Grande Armée suffering catastrophic losses due to harsh winter conditions, disease, and Russian scorched-earth tactics. French invasion of Russia

War of the Sixth Coalition (1813–1814)

Following the Russian campaign, the Sixth Coalition—comprising Russia, Prussia, Austria, Sweden, Britain, Spain, and Portugal—formed against France. The coalition achieved a decisive victory at the Battle of Leipzig in October 1813. In 1814, coalition forces captured Paris, leading to Napoleon's abdication and exile to Elba.

The Hundred Days and the Battle of Waterloo (1815)

In 1815, Napoleon escaped from Elba and returned to France, initiating the period known as the Hundred Days. He was ultimately defeated at the Battle of Waterloo on June 18, 1815, by a coalition force led by the Duke of Wellington and Field Marshal Gebhard Leberecht von Blücher. Napoleon was subsequently exiled to Saint Helena, where he died in 1821.

Consequences

• –

  Political Changes: The wars led to the redrawing of European borders and the rise of nationalism.
