Queen Jeonghui
Queen Jeonghui (Hangul: 정희왕후, Hanja: 貞熹王后; 8 December 1418 – 6 May 1483), of the Papyeong Yun clan, was a posthumous name bestowed on the wife and queen of Yi Yu, King Sejo. She was Queen of Joseon from 1455 until her husband's death in 1468, after which she was honoured as Queen Dowager Jaseong (자성왕대비) during the reign of her son, Yi Hwang, King Yejong, and as Grand Queen Dowager Jaseong (자성대왕대비) during the reign of her grandson, Yi Hyeol, King Seongjong. Lady Yun was the first Joseon royal consort to receive the title of Grand Queen  Dowager. She also served as regent for her young grandson between 1468-1476 with her daughter-in-law, Queen Dowager Insu as adviser, after the sudden death of Yejong in 1469. Biography. Early life and Marriage. The future Queen Jeonghui was born on 8 December 1418 during the eighteenth year of King Taejong's reign as the 9th child within 10 siblings. Her father was Yun Beon, who would later become Chief State Councillor, and her mother was Lady Yi of the Incheon Yi clan. She married Grand Prince Suyang at the age of ten in 1428, on the thirteenth  day of the twelfth lunar month in the tenth year of King Sejong's reign. She was given the titles of Grand Princess Consort Samhanguk (삼한국대부인, 三韓國大夫人) and eventually, Grand Internal Princess Consort Nakrang (낙랑부대부인, 樂浪府大夫人). Lady Yun became Queen upon her husband's accession to the throne in 1455, after a coup d'état against his nephew, King Danjong. Regency. In 1469, King Yejong died suddenly at the age of 20, and was succeeded by his youngest nephew and Queen Jeonghui's grandson, Prince Jalsan, who was third in the line of succession to the throne, rather than his own  son, Grand Prince Jean. The official reasons given were that Grand Prince Jean was deemed to young at 4 years old to become King and that Prince Wolsan was too sickly, but the more likely reason for this choice was Jalsan's marriage to the daughter of the powerful Han Myeong-hoe. As Seongjong was only 13 at the time of his accession, Queen Jeonghui ruled the nation as regent, along with her daughter-in-law and Seongjong's mother, Queen Insu (whose husband had never actually been King). During her regency, common farmers were granted the right to cultivate  fields that had originally belonged to the military. In 1474, the code of law, first ordered by King Sejo, was completed and put into effect. Later life. Queen Jeonghui's regency ended in 1477 and she died on 6 May 1483, in the fourteenth year of King Seongjong's reign. Family.
