Wang Ko

Wang Ko (died 1345), Mongol name Oljeitu, was a Goryeo prince and Yuan-dynasty King of Shen, son of Duke Gangyang. In 1316 he received the Shen fief from his uncle King Chungseon.

After 1320 he twice intrigued at court to seize the Goryeo throne, securing Chungseon's exile to Tibet, but Emperor Yingzong's assassination in 1323 and Bayan's downfall in 1340 ruined his plans. He briefly acted as king after Chunghye's fall in 1343, returned to Goryeo and died there in 1345, when his grandson Toghtua Bukha inherited Shen.
