1800
Volta's Electric Pile
Alessandro Volta stacked discs of zinc and copper separated by brine-soaked cloth and drew from them a steady, unnatural current - the first battery. Reported to London's Royal Society, his pile handed chemists and physicists a tool that would crack water into its elements and remake the century. Napoleon, fascinated, summoned Volta to Paris, awarded him a medal, and declared the invention the foundation of a new science.
Usman dan Fodio's Preaching Spreads
Across the Hausa cities of what is now northern Nigeria, a Fulani scholar named Usman dan Fodio preached a stricter, reforming Islam, gathering students and enemies in equal measure. His sermons against corrupt emirs were laying the kindling for a jihad that would forge the vast Sokoto Caliphate. By 1808 his followers had overthrown the Hausa kings and established the largest state in nineteenth-century West Africa.
Library of Congress Founded
John Adams signed a modest appropriation - $5,000 - for books to furnish the new Capitol in a swampy river town called Washington. From that seed, tucked into a congressional act on relocation, would grow the largest library on earth, and one of the republic's quiet temples. After the British burned the original collection in 1814, Jefferson sold Congress his own 6,487 volumes to rebuild it.
Nguyen Offensive in Vietnam
Gia Long's forces pressed north against the crumbling Tay Son dynasty, gathering the armies and French-built forts that would unite Vietnam within two years. The wars of reunification had been grinding for thirty years. Hue, soon to become the new imperial capital, was being refitted in stone for a dynasty that would last until 1945.
Qianlong's Shadow in Qing China
The ancient Qianlong Emperor had died the year before, but his favorite Heshen, the most corrupt courtier in Chinese history, was forced to hang himself in his prison cell by the new Jiaqing Emperor. Heshen's confiscated fortune rivaled the state treasury. The Qing rot had an institutional face, and Beijing had just cut it off.
Napoleon Wins Marengo
Crossing the Alps with cannon dragged over snowfields, Bonaparte surprised the Austrians in the Piedmont and nearly lost - until Desaix rode up at dusk and died turning the rout into triumph. Marengo confirmed Napoleon's power at home and his grip on northern Italy. David's painting of Napoleon on a rearing horse at the pass has become one of the most iconic images in Western art.
Adams Moves Into White House
John and Abigail Adams arrived at the half-finished President's House in a raw, unpaved capital. Abigail hung laundry in the unfinished East Room. Within months Adams would lose the election to Jefferson and leave - the first peaceful transfer of power between bitter rivals in the new nation. Adams's prayer that heaven bestow its blessings on the house was later carved into its mantelpiece by Franklin Roosevelt.
