Möngke Khan

As Great Khan, Möngke took on the role of a meticulous administrator and a relentless conqueror. He carried out crucial reforms to centralize the empire's taxation and bureaucracy, resolving long-standing corruption. Under his direct leadership, the Mongol Empire launched its most ambitious dual-expansion campaigns. He dispatched his younger brother Hulagu to conquer the Middle East and ordered another brother, Kublai, to conquer the Southern Song Dynasty in China, aiming to bring the entirety of the known world under Mongol rule.

Möngke was famous for his strict, simple lifestyle and his deep interest in diverse philosophies. He welcomed foreign emissaries, including the Franciscan friar William of Rubruck. During an audience, Möngke shared a famous philosophical parable: 'We Mongols believe there is but one God, by Whom we live and by Whom we die. But just as God gave different fingers to the hand, so has He given different ways to men.' This showed his pragmatic, tolerant approach to the many religions within his vast domain.

Despite his philosophical tolerance, Möngke was deeply superstitious and strictly followed traditional Mongol rituals. He relied heavily on scapulimancy—predicting the future by burning sheep's shoulder blades and reading the cracks. It is said he never made a major decision, including his final campaign into China, without consulting these bone readings. In 1259, while personally leading the siege against the Southern Song at the formidable Diaoyu Castle in Sichuan, he contracted a severe illness (likely cholera or dysentery) and passed away at the age of 50. His sudden death forced a halt to the Mongol campaigns worldwide and triggered a bitter civil war between his brothers Kublai and Ariq Böke.
