Wikipedia Overview

Yi In-jwa's Rebellion, also known as the Musin Rebellion, after The name of the year in which it occurred in the sexagenary calendar, was an attempted coup d'état in March 1728 by a coalition of the radical faction of the Namin and the excluded Soron faction. After the death of King Gyeongjong and the ascension of King Yeongjo to the throne, the position of the Noron faction was restored, and Soron, who had instigated the rebellion under the pretext of protecting King Gyeongjong, was punished and excluded from power. Shortly after ascending to the throne, Yeongjo pursued a policy of equal recruitment, believing that factional strife was detrimental to the country's development. In response, the radical faction of the Soron group justified their rebellion by raising suspicions about the circumstances of King Gyeongjong's death and claiming that King Yeongjo was not the legitimate heir of King Sukjong, thereby securing their power. The rebellion began on March 15 when Yi In-jwa captured Cheongju Castle. The rebel forces, marching toward Hanyang, were defeated by the royal army, and the support from the Yeong and Honam regions was also suppressed by local forces, leading to the suppression of the rebellion.
