Napoleon fought a series of wars against shifting coalitions of European powers (Britain, Austria, Russia, Prussia).
He had major victories such as Austerlitz (1805), often seen as his greatest triumph, and Jena-Auerstedt (1806) against Prussia.
He created a French-dominated empire across much of continental Europe, placing family members on thrones (e.g., Joseph in Spain, Louis in Holland).
His Continental System (1806) aimed to economically isolate Britain, but it backfired, hurting France’s allies and fueling smuggling.
The wars spread revolutionary ideas like legal reforms and nationalism, but also triggered resistance movementsin Spain, Italy, and Germany.
Collapse of the Napoleonic Empire
The empire became overstretched, with too many occupied territories to control effectively.
The Peninsular War (1808–1814) drained resources as Spanish guerrillas, aided by the British (under Wellington), tied down large French forces.
Growing nationalism in conquered countries undermined French control and increased opposition.
The failed invasion of Russia (1812) was the decisive turning point — harsh winter, poor supply lines, and Russian scorched-earth tactics destroyed much of Napoleon’s Grand Army.
Military Defeat (1813–1814)
After Russia, Napoleon’s weakened army faced a new coalition of Britain, Russia, Prussia, and Austria.
He was defeated at the Battle of Leipzig (1813), also called the “Battle of Nations,” the largest battle in Europe before WWI.
By 1814, coalition forces invaded France, Napoleon abdicated, and he was exiled to the island of Elba.
The Hundred Days (1815)
Napoleon escaped Elba and regained power in March 1815, welcomed by his former soldiers.
His return alarmed Europe, leading to the Seventh Coalition led by Britain and Prussia.
Napoleon was defeated at the Battle of Waterloo (June 1815) by Wellington and Blücher.
He was exiled again, this time to Saint Helena, where he remained until his death in 1821.
Common Mistake
Students often over-focus on Waterloo as the sole reason for Napoleon’s fall, forgetting that the collapse began with Russia and Leipzig.
Some forget the importance of nationalism and resistance in Spain and Germany, which drained French resources and weakened control.
Exam technique
When writing about Napoleon’s downfall, show stages (overextension → Russia → Leipzig → Waterloo) instead of jumping straight to his final defeat.
Always link military events with political impact. For example, the Russian disaster destroyed Napoleon’s prestige and encouraged other nations to resist.
Active recall
To what extent was the invasion of Russia the key turning point in the collapse of Napoleon’s empire?
Examine the reasons for Napoleon’s final defeat in 1815.
How significant was nationalism in the downfall of Napoleon’s empire?
