1806
Jena-Auerstedt
On a single October day, two French armies annihilated the Prussian military machine that Europe had feared since Frederick the Great. Napoleon rode into Berlin two weeks later. Humiliation drove Prussian reformers - Stein, Scharnhorst, Clausewitz - to rebuild the army that would one day unify Germany. Hegel, watching Napoleon ride through Jena, called him the world-soul on horseback, history in the saddle.
Cape Colony Taken by Britain
British troops landed at Table Bay and, after a short battle with the Dutch garrison, occupied the Cape. It was a strategic move against French-allied Holland; it became permanent. Tens of thousands of Afrikaners would eventually trek inland to escape English rule, and the Cape became the hinge of British power in southern Africa.
Confederation of the Rhine
Sixteen German princes, bribed and bullied by Napoleon, formally left the Holy Roman Empire and joined a French-protected Confederation. Three weeks later Francis II laid down the thousand-year imperial crown. The map of central Europe was a blank slate awaiting whatever Paris chose to draw. The empire that Charlemagne had founded and Voltaire had mocked as neither holy, nor Roman, nor an empire, was finally dead.
Holy Roman Empire Dissolved
Francis II, under pressure from Napoleon and abandoned by the Rhenish princes, formally laid down the thousand-year-old crown of the Holy Roman Empire. The empire had long been, in Voltaire's gibe, neither holy, Roman, nor an empire, but its dissolution closed a medieval institution that had defined central Europe since Charlemagne.
Continental System Decreed
From Berlin, Napoleon ordered Europe to close its ports to British ships. No tea, no sugar, no Manchester cotton. The blockade was meant to strangle London and instead starved French allies, spawned smugglers from Hamburg to Salonika, and gave Britain a useful grievance against Russia. The system's enforcement eventually drew Napoleon into the disastrous Spanish and Russian campaigns that would destroy his empire.
