Petrus Peregrinus writes on magnets
A French crusader-engineer at the siege of Lucera wrote the Epistola de Magnete, the first systematic account of magnetic phenomena. He identified poles, the concept of a floating compass, and the attraction-repulsion law. His pragmatic experiments anticipate the scientific method. Roger Bacon praised him as the finest experimental scientist of the age, and his magnetic studies influenced European navigation for the next two centuries.
Nasir al-Din Tusi dies at Baghdad
The polymath who had served both Ismaili grand masters and Mongol khans died in the city Hulagu had sacked eleven years earlier. His contributions to astronomy, mathematics, ethics, and Shia theology made him one of the most versatile intellects of the medieval Islamic world, a man who survived catastrophe by being indispensable.
Marinids conquer Marrakesh
The Berber Marinid dynasty captured the old Almohad capital, ending any serious attempt by the Almohads to reclaim their empire. Morocco entered a period of prosperity under Marinid viziers who patronized madrasas in Fez and fought on Iberian battlefields. The dynasty's greatest architectural legacy would be the exquisite Bou Inania madrasa in Fez, a masterpiece of carved stucco, zellige tilework, and cedarwood that still functions today.
Merenid dynasty captures Marrakesh
The Marinid Berbers, having fought the Almohads for decades, finally seized Marrakesh and ended the last pretense of Almohad power. Morocco entered a new era under the Marinids, who built spectacular madrasas in Fez, patronized Maliki scholarship, and launched occasional futile jihads across the Strait of Gibraltar. Their rule stabilized Morocco and attracted scholars and artisans from al-Andalus who enriched the kingdom's intellectual and artistic life.
