Editing Yeonsan-gun (section)

==Two Purges==
The Crown Prince grew up and succeeded Seongjong in 1494. During his early reign, he was a wise and able administrator who strengthened the national defense and aided poor people. He also showed signs of the violent side when he killed Jo Sa-so, one of his tutors, soon after becoming the king. He eventually learned what happened to his biological mother and tried to restore his mother's title and position posthumously. When the government officials belonging to the political faction called Sarim opposed his efforts on the account of Seongjong's will, he was displeased and looked for ways to eliminate them. In 1498 Kim Il Son, a disciple of Kim Jong-jig, included a paragraph in the royal record that was critical of King Sejo's usurpation of the throne in 1455. Kim Il Son and other followers of Kim Jong-jik were accused of treason by a rival faction, which gave Yeonsangun enough cause to order the execution of many Sarim officials and mutilation of Kim Jong-jik's remains. This is called First Literati Purge of 1498(무오사화 戊午士禍).

In 1504, Im Sa-hong revealed to Yeonsangun details of his mother's death and showed blood-stained piece of clothing, which was allegedly blood vomited by her after drinking poison. On March 20, 1504, he beat to their death two of his father's concubines, for their responsibility for his mother's death. His grandmother, Grand Queen Insu died when she was pushed by Yeonsagun after one of the altercations. He executed many government officials who supported the execution of his mother, now posthumously known as Queen Jeheon, and ordered the grave of Han Myeong-hoi to be opened and the head cut off the corpse. This is known as the Second Literati Purge of 1504(갑자사화 甲子士禍).
