Mongol envoys slaughtered at Otrar
The Khwarazmian governor of Otrar massacred a Mongol trade caravan and its envoys, accusing them of espionage. Genghis Khan, informed of the killings, reportedly climbed a hill and wept for three days before gathering his army and riding west. The governor's rash act unleashed the most destructive invasion the Islamic world had ever experienced, a catastrophe from which Central Asia would not recover for centuries.
Salamanca founded as a studium generale
Alfonso IX of Leon granted a royal charter to the schools of Salamanca, converting them into a full university. Students from Iberia and beyond flocked to the stone town on the Tormes to study law, medicine, and Aristotle translated from the Arabic. By the next century Salamanca would rank alongside Paris, Oxford, and Bologna as one of Europe's four great universities.
Al-Kamil becomes Ayyubid sultan of Egypt
On the death of his father al-Adil, the young sultan al-Kamil inherited Egypt at the worst possible moment, with a Crusader fleet bearing down on Damietta. His patient diplomacy and willingness to negotiate would define the era, culminating in his extraordinary deal with Frederick II over Jerusalem. He offered the Holy City to the excommunicated emperor without a drop of blood, stunning both Muslim and Christian hardliners.
Grand Mosque of Qazvin expanded
Under Khwarazmian patronage, master craftsmen expanded the Friday mosque at Qazvin with brick muqarnas and Kufic inscriptions. A year later the city would be sacked by the Mongols. The surviving mosque preserves a snapshot of Iranian architecture on the eve of catastrophe. Its great prayer hall, with its interlocking vaults and elegant calligraphy, stands as testament to a civilization about to be shattered.
