In 1493, after roughly 25 years on the throne, Seongjong eventually fell ill and died. The succession came up to his eldest son and the crown prince Yeonsan finally ascended the throne as the tenth king of Joseon. The Queen Consort was elevated to the rank of royal queen dowager and granted the honorary name when writing the tombstone of Seongjong. Someone within the court learned of Yun's private affairs and provided the cause of the massacre of the
Sarim faction through sudden death. But in 1494, the young king eventually learned of what had happened to his biological mother and attempted to posthumously restore her titles and position. In 1497, during Yeosangun's third year of reign, she received the honor of Jasun (慈順) and Hwahye (和惠) in 1504 for her posthumous title. Because
Queen Dowager Insu held enormous influence over the court due to her father and clan alliances, this brought indifferences between her and her grandson's rule as king. These inconsolable differences soon led to a brutal clash; leaving the Queen Dowager to die in 1504 after King Yeonsan pushed her in an altercation when he found out his grandmother was behind the cause of his birth mother's death. After finding out more information on his biological mother with the help of
Im Sa-hong, King Yeonsangun caused a purge in connection with the death of his mother, Queen Jeheon, and executed the ministers and members of the royal family that were involved. No one from the palace involved was safe; the King ordered to beat to death, or some say that they were dismembered to pieces, two of his father's concubines, Royal Consort Gwi-in of the Chogye Jeong clan and Royal Consort Gwi-in of the Yeongwol Eom clan, for their part in his mother's death. It was said that the King even went as far as to ordering to open the grave of
Han Myŏnghoe, the father of
Queen Jangsun and
Queen Gonghye, to be opened and have the head to be cut off the corpse posthumously. This punishment was considered the most severe, but he didn't stop and continued to punish officials who were simply present at the royal court at that time; for the crime of not preventing the actions of those who abused his mother. At some point after the bloody confrontations, the King finally went to his adoptive mother's, Queen Dowager Jasun, quarters and ordered the Queen Dowager to come out of her living quarters. When doing so, this caused the Queen Dowager to be held at sword point, but because the current Queen consort,
Queen Jeinwondeok, was around when the chaos started, she was able to intervene to protect her legal mother-in-law from her husband. This was known as the
Second Literati purge to which brought Im Sa-hong and his allies be promoted while receiving many important offices and other rewards. In 1506, a Grand Prince concluded that the reign of his older half-brother King Yeonsan needed to be stopped as the nation was to be in shambles and needed a reliable strong ruler, not a violent tyrant. So during a revolt, the leading forces of the anti-government advocated the establishment of Grand Prince Jinseong (later
King Jungjong) on the throne and consented. Thus a coup insinuated against the king and eventually bringing the grand prince to demote the royal couple, as Prince Yeonsan and Princess Consort Geochang, to
Ganghwa Island. The now King Jungjong wanted to spare their children, but because the court officials didn't want to risk another uprising, they pushed the remaining two sons of the royal couple to be sentenced to death by poisoning right after the coup, despite that the new king was reluctant to enforce such punishment. This left
Princess Hwishin to be spared as she was already married, but her royal titles and the house given by her father were eventually taken back. But with the opinions of Yun Sun () and other court officials, the king gave her titles and house back in 1508. This followed with a visit from the king as well to see how his half-niece was doing after the ordeal. The Queen Dowager lived a quiet life after the succession of her son, and eventually died on 13 December 1530 at the age of 68 within
Gyeongbokgung's Dong Palace. Her son made a statement highlighting her virtues, "The Queen Mother was benevolent and harmonious with her family and did not seek a government post for her maternal relatives" (). For her posthumous title, "Jeong" () was for the achievement of great thoughts, and "Hyeon" () was for the appearance of conduct outside the court; becoming Queen Jeonghyeon (). She is buried in
Seonreung (
Gangnam,
Seoul, South Korea) with her husband and his first wife, Queen Gonghye. ==Family==
