The Yuan temple name later given to Genghis Khan was Taizu.
Genghis Khan was born Temüjin and ruled the Mongol Empire from 1206 until his death in 1227. The title “Genghis Khan” was his Mongolian imperial title, not the Chinese-style temple name used in later dynastic histories.
When his grandson Kublai Khan established the Yuan dynasty in China in 1271, he presented Genghis as the dynasty’s founding ancestor. Kublai therefore bestowed on him the temple name Taizu, written 太祖 and meaning “Supreme Progenitor.” He also gave him the posthumous name Shengwu Huangdi, or “Holy-Martial Emperor.”
Taizu is a conventional Chinese temple name often associated with a dynasty’s founder. It should not be confused with Shizu, the temple name of Kublai Khan, or with Chengzong and Wuzong, which belonged to later Yuan emperors. In Chinese imperial records, Genghis Khan is thus Emperor Taizu of the Yuan dynasty.
