Huijong (21 June 1181 – 31 August 1237), personal name Wang Yŏng, was the 21st king of the Goryeo dynasty of Korea.
[2] Huijong, knowing that he had to lull Ch'oe Ch'ung-hŏn into a false sense of security in order to be able to kill him, promoted him to Prime Minister of the State.
This title was the one most often given out during the time of military rule to people such as Chŏng Chung-bu, Yi Ŭi-min, and even Ch'ung-hŏn's father posthumously.
Huijong also named Ch'ung-hŏn the Royal Protector, the greatest honor of the time, which was usually only given to relatives of the King.
He used it to obliterate three rebellions, one led by his slave, another by Silla partisans, and one by his nephew Pak Chin-jae (박진재; 朴晋材).
