The siege of Diaoyucheng, alternatively the siege of Diaoyu Castle, was a battle between the Southern Song dynasty and the Mongol Empire in 1259.[1] It occurred at the Diaoyu Fortress in modern-day Hechuan District, Chongqing, China. Möngke Khan, the fourth khagan of the Mongol Empire, lost his life in this battle, making it the only battle where the Mongols lost their khagan during their campaigns of conquest. This battle was preceded by the siege of Baghdad in 1258. The siege of Diaoyucheng was a setback for the Mongol conquest.
