Sukjong (2 September 1054 – 10 November 1105), personal name Wang Ong, was the 15th king of the Goryeo dynasty of Korea.
Sukjong rose to the throne in 1095 upon the abdication of his young nephew, King Heonjong.
[1] He oversaw various internal innovations, including the distribution of the country's first brass coins (in 1102) and the construction of the new Southern Capital (Namgyeong, present-day Seoul).
Unable to repel the Jurchens by force, he sent his general Yun Kwan to raise an army and repulse them.
Challenges of Sukjong's reign can be summarized in his own words:[4] Since I was entrusted with the affairs of the state, I have always endeavoured to cautiously maintain diplomatic ties with Liao in the north and serve the Song in the south, while these days the Jurchen in the east have become enemies to be reckoned with.
