1766
Stamp Act Repealed
Colonial boycotts had hurt British merchants; Parliament backed down. But the same day it passed a Declaratory Act asserting the right to legislate for America 'in all cases whatsoever.' Americans cheered the repeal and read past the declaration. The lesson they learned: resistance works. New York erected a statue of George III in gratitude, which the Sons of Liberty would melt into musket balls a decade later.
Burmese Sack Ayutthaya
Konbaung armies, led by Hsinbyushin, besieged the Siamese capital after a year's blockade. When it fell in April 1767, they burned the 400-year-old royal city - palaces, monasteries, libraries - to the ground. Siam's monarchy fled; its history had to be rewritten from monks' memories. The destruction was so thorough that modern Thai historians still rely on Burmese and European sources to reconstruct the kingdom's final century.
Bougainville Begins Pacific Circumnavigation
Louis-Antoine de Bougainville sailed from Nantes on a three-year voyage around the world, the first Frenchman to circumnavigate the globe. He would encounter Tahiti, chart Samoan waters, and nearly wreck on the Great Barrier Reef. His naturalist described a flowering vine in Rio that still bears Bougainville's name in every garden on earth.
Cavendish Isolates Hydrogen
Henry Cavendish, the eccentric rich London aristocrat who spoke to his servants by note, reported to the Royal Society on 'inflammable air' - a gas that burned with a pale flame and weighed almost nothing. He had discovered hydrogen, though he called it phlogiston-rich air and refused to speak at the meeting.
