How was Napoleon finally defeated in Europe
frutty [35]

At Waterloo in Belgium, Napoleon Bonaparte suffers defeat at the hands of the Duke of Wellington, bringing an end to the Napoleonic era of European history. The Corsica-born Napoleon, one of the greatest military strategists in history, rapidly rose in the ranks of the French Revolutionary Army during the late 1790s.

The Waterloo Campaign was fought between the French Army of the North and two Seventh Coalition armies, an Anglo allied army and a Prussian army, that defeated Napoleon in the decisive Battle of Waterloo, forced him to abdicate for the second time, and ended the Napoleonic Era.
