Kublai Khan's Muslim Astronomers and the Yuan Calendar Reform

In this episode of Fexingo History, Lucas and Luna explore a lesser-known facet of Kublai Khan's rule: his patronage of Muslim astronomers from the Islamic world. After conquering the Song dynasty, Kublai established the Islamic Astronomical Bureau in Dadu (modern Beijing), staffed by scholars like Jamal al-Din and the Persian astronomer Shams al-Din al-Bukhari. They brought advanced instruments—including an armillary sphere, an astrolabe, and a celestial globe—and knowledge of Ptolemaic astronomy. This led to the creation of the 'Wan Nian Li' (Ten-Thousand-Year Calendar), a lunisolar calendar that corrected errors in earlier Chinese systems. The episode delves into the cultural exchange at the Yuan court, the competition between Chinese and Islamic astronomers, and how this collaboration influenced later Ming dynasty astronomy. We also discuss the broader Mongol policy of employing foreign experts, from Persian administrators to Tibetan monks, and how Kublai's openness to Islamic science reflected his cosmopolitan vision of empire. Specific terms and figures include Jamal al-Din, Shams al-Din al-Bukhari, the Islamic Astronomical Bureau, the armillary sphere, the Wan Nian Li, and the Yuan Shi (official history). #KublaiKhan #YuanDynasty #IslamicAstronomy #JamalAlDin #WanNianLi #CalendarReform #Dadu #MongolEmpire #Astrolabe #ArmillarySphere #CulturalExchange #PersianScholars #ShamsAlDin #History #FexingoHistory #MedievalScience #ChinaHistory #IslamicGoldenAge Keep every episode free: buymeacoffee.com/fexingo
