Jungjong coup
In 1506, the 12th year of King Yeonsan, a group of officials – notably Pak Wŏnjong, Sŏng Hŭian, Yu Sunjŏng and Hong Kyŏngju plotted against the despotic ruler. They launched a coup on September 2, 1506, deposing the king and replacing him with his half-brother, Grand Prince Jinseong. The king was demoted to prince, and exiled to Ganghwa Island, where he died a few weeks later. Consort Jang Nok-su, who was regarded as a 'femme fatale' who had encouraged Yeonsangun's misrule, was beheaded. Yeonsangun's young sons were also killed.
