1215
Magna Carta sealed at Runnymede
Cornered by his rebellious barons in a Thames-side meadow, King John pressed his seal to a charter limiting royal power. He repudiated it within weeks, but the document outlived him and seeded centuries of constitutional argument about the limits of a crown. Its sixty-three clauses would be cited by English parliamentarians, American colonists, and civil liberties lawyers for the next eight hundred years.
Mongols capture Zhongdu, Jin capital
After a lengthy siege, Genghis Khan's armies stormed the Jin capital on the site of modern Beijing. For weeks fires burned through the wooden city. Survivors described bones heaped in the streets. The Jin court fled south to Kaifeng and the steppe rode west. A generation later Kublai Khan would choose the same site for his new capital of Dadu, future heart of the Yuan dynasty.
Inuit Thule culture expands across Arctic
Thule whalers from the Bering Strait pushed east along the Arctic coast, displacing the earlier Dorset people as they went. With kayaks, umiaks, and dogsled teams they reached Greenland within a century, bringing toggling harpoons and a taste for bowhead whales. Their ingenious adaptation to polar conditions, including semi-subterranean houses insulated with whale bone and sod, set the template for all subsequent Inuit cultures.
Fourth Lateran Council convenes in Rome
Innocent III summoned the largest church council of the Middle Ages. Its canons ordered annual confession, forbade clergy from blessing ordeals, required Jews and Muslims to wear distinctive dress, and defined transubstantiation as dogma, reshaping daily Christian life. The council's seventy decrees touched every corner of medieval existence, from marriage and inheritance to preaching and the conduct of crusades.
Aquinas's father plans his religious career
The Count of Aquino sent his young son Thomas, destined for the abbey of Monte Cassino, to begin his education there under Benedictine tutelage. The boy would eventually run away to join the new Dominicans, to his family's horror and later pride. His brothers kidnapped him and held him prisoner for a year in a family castle, trying without success to shake his vocation.
