Napoleon Seizes Power
Out of the chaos of the French Revolution rose an artillery officer from Corsica who seized power in a coup in 1799 and crowned himself emperor five years later. Napoleon Bonaparte beat nearly every army in Europe — shattering the Austrians and Russians at Austerlitz in 1805 — and remade the continent, spreading the Revolution's legal reforms in the Napoleonic Code even as he betrayed its liberty. Britain, unbeaten at sea after Trafalgar, funded coalition after coalition against him. In 1812 he invaded Russia with roughly 600,000 men and returned with a fraction of them, destroyed by distance, winter, and an enemy who simply withdrew and burned the country behind them. The coalitions closed in, and after a brief return from exile he was finished for good by the British and Prussians at Waterloo in 1815.
Prolonged chaos creates demand for order; a single figure concentrates power by promising to supply it.
