Zhenjin

Zhenjin (1243–1286), son of Kublai Khan and Chabi Khatun, was the Yuan dynasty's first crown prince. The monk Haiyun named him, meaning true gold. Made Prince of Yan in 1261, he was named heir in 1273. Tutored by Han Confucian scholars, he befriended the Tibetan lama Phagpa.

In 1285 a censor proposed Kublai abdicate in his favour, enraging the old emperor; Zhenjin died fearful and ill in January 1286, before ever reigning. His son Temür succeeded Kublai and posthumously honoured him as Emperor Yuzong.
