Yeongjo
Twenty-first king of Joseon, known for his impartiality policy and tax reform, and for the death of his son
After Yi In-jwa's Rebellion he pursued the policy of impartiality (tangpyeong) to uproot factionalism, setting up the Tangpyeong stele before the Seonggyungwan in 1742. He cut back the seowon that served as factional bases and took away the personnel section chiefs' right to name their successors. In 1750 the Equalised Service Law reduced the military cloth tax from two bolts a year to one. He compiled the Sok daejeon, restored the sinmungo drum and dredged the Cheonggyecheon. The death of his son Crown Prince Sado in 1762 is known as the Imo Incident.
