Hyejong of Goryeo (912 – 23 October 945) (r. 943–945) was the second King of Goryeo. He was preceded by King Taejo and succeeded by Jeongjong, 3rd Monarch of Goryeo. Early life Hyejong was born to King Taejo and his second wife, Janghwa of the "Oh" clan. She was the daughter of the Magistrate of Naju, Oh Da-ryeon. Taejo met and married her while serving in Naju as a general of Taebong under Gung Ye. In 921, Hyejong was proclaimed Crown Prince and Royal Successor with support from General Bak Sul-Hui. Almost immediately after being named Crown Prince, Hyejong followed his father Taejo into battle against Later Baekje and played a major role in numerous victories. In 943, Hyejong rose to the throne upon his father's death. Reign Hyejong's reign was marked with conspiracy and power struggles among Taejo's sons. The first of these conspiracies was led by Princes Wang Yo and Wang So, sons of Taejo and his third consort, Queen Sinmyeongsunseong of the Chungju Yu clan, which possessed considerable political influence. Upon realizing the conspiracy by the two princes, Wang Gyu warned Hyejong of the conspiracy, but plotted to put his grandson, one of Hyejong's younger half-brothers, on the throne when Hyejong did nothing to stop the conspiracy of the two princes. Death Hyejong died in 945, during the second year of his reign from mercury poisoning in his bath water. He had a disease most commonly known as eczema which caused red itchy patches on his skin and difficulty breathing. Although he had a son who was named crown prince, he was succeeded by his third brother Wang Yo, who claimed the throne by force with the backing of their fourth brother Wang So and subsequently crowned as Jeongjong.
