1781
Cornwallis Surrenders at Yorktown
Trapped on a Virginia peninsula by Washington's army and Rochambeau's French regulars, with de Grasse's fleet blocking the bay, Cornwallis stacked his arms as his band supposedly played 'The World Turned Upside Down.' It was, effectively, the last major battle of the American Revolutionary War. Lord North, receiving the news in London, paced the room crying 'Oh God, it is all over,' and resigned within months.
Kant's Critique of Pure Reason
An unmarried, punctual logic professor in Königsberg published a 800-page argument that reason could not know things in themselves - only how the mind organized appearances. It reset philosophy on a new axis. Kant had waited until his late fifties to write it. For the next century, every German thinker would try to climb out of it.
Herschel Discovers Uranus
A German-born organist in Bath, sweeping his homemade reflecting telescope through Gemini, spotted a greenish disc that moved. William Herschel thought it was a comet. Within months the astronomers agreed: it was a planet, the first found since antiquity. He named it for George III; everyone else called it Uranus.
Joseph II Abolishes Serfdom in Habsburg Lands
In a single edict, Joseph freed millions of peasants from personal bondage across his scattered realms. Landlords raged; reformers cheered. The reform was sweeping, rushed, and largely reversed by Joseph's heirs - but serfdom as a legal institution had cracked. The idea, once in the air, could not be recalled.
Articles of Confederation Ratified
Maryland at last ratified, four years after the Continental Congress had adopted them. The United States had a constitution - barely. The Articles created no executive, no federal courts, and no power to tax. They would hold the new nation together for seven thin years before being quietly replaced. Their weakness in commerce and defense drove the very men who wrote them to call the Philadelphia Convention.
