Sunjong (28 December 1047 – 5 December 1083), born Wang Hyu, later renamed Wang Hun, was briefly the 12th king of the Goryeo dynasty of Korea. He was the eldest son of King Munjong and the older brother of King Seonjong. He had been confirmed as heir to the throne in 1054 and during his time as heir, his father actively cultivated his status both domestically and internationally, charging him with leading banquets amongst the Goryeo nobility and making him treat with envoys from the Song dynasty of China.[1] However, he died within a year of his ascension in 1083; his four month long reign was the shortest in Goryeo's history.[2]
