The Chinese-style title Genghis Khan gave Muqali in North China was Guo Wang.
In Mongolian usage, the title was rendered gui ong or kuo-wang, corresponding to the Chinese guo wang, often translated as “Prince of State” or “King of the State.” Genghis Khan granted it to Muqali while entrusting him with authority over North China.
Muqali, a member of the Jalair tribe, was one of Genghis Khan’s most trusted commanders. When Genghis turned west to campaign against the Khwarazmian Empire, Muqali remained in China as his viceroy and directed the war against the Jin dynasty. He received unusually broad autonomy for a non-Chinggisid commander.
Muqali also received the title taishi, meaning “Grand Preceptor,” and adopted Chinese-style court rituals and robes. Guo Wang was therefore not simply a battlefield rank: it signaled delegated political authority in conquered China. Gur Khan was a different steppe title, Darughachi referred to an administrative official, and Taishi was Muqali’s additional title rather than the answer sought here.
