First gold florin struck in Florence
The Florentine commune minted a gold coin stamped with the city's lily and the image of Saint John the Baptist. At 3.5 grams of fine gold, the florin became the standard currency of European trade, displacing Byzantine bezants and Muslim dinars from the ledgers of Italian bankers. Its reliable purity made it the dollar of medieval Europe, accepted from London to Constantinople without question.
Innocent IV authorizes torture for Inquisition
By the bull Ad Extirpanda, the pope allowed inquisitors to use torture to extract confessions from suspected heretics, provided no blood was shed and no limbs broken. The fine distinctions of medieval legal theory were folded into centuries of judicial cruelty. The bull specified that torture could be applied only once, a limitation that inquisitors circumvented by declaring each session a continuation rather than a repetition.
Alfonso X the Wise becomes King of Castile
The son of Ferdinand III inherited a kingdom stretching from the Bay of Biscay to the Strait of Gibraltar. He commissioned translations, law codes, and astronomical tables in Castilian rather than Latin, nurturing a new vernacular literature and the famous Alfonsine Tables. His Siete Partidas, a comprehensive legal code modeled on Roman and canon law, would influence Spanish jurisprudence for the next five centuries.
Inquisition in Languedoc intensifies under Dominicans
Dominican inquisitors in Toulouse and Carcassonne conducted systematic house-to-house interrogations, maintaining meticulous registers of testimony that would serve as templates for later inquisitorial procedure. Neighbors informed on neighbors; the fear of denunciation became as effective as the pyre itself in crushing Cathar sympathies. The records they kept, preserved in archives at Toulouse, are now invaluable sources for understanding daily life in medieval southern France.
