Sukjong
Sukjong of Joseon was the 19th monarch of the Joseon Dynasty, reigning from 1674 to 1720. His reign, spanning 46 years, was one of the longest in Korean history and was marked by significant political upheaval and a shift in court power dynamics. He ascended to the throne at the young age of 14. A key feature of his rule was the frequent and dramatic shifts in the balance of power between the Westerners (Seoin) and Southerners (Namin) political factions. Sukjong was known for his strategic manipulation of these factions, often exiling or reinstating leaders to maintain his own authority. This practice, known as "hwanguk" (royal coup), led to considerable instability but also allowed Sukjong to exert considerable personal influence over state affairs. He personally oversaw military campaigns, notably against the Jurchens in the north. His reign also saw advancements in scholarship and the arts, with notable figures contributing during his time. Sukjong is remembered for his strong will and his ability to navigate complex political landscapes, ultimately consolidating royal power. He died in 1720 and was succeeded by his son, Gyeongjong.
