Dethronement
In 1506, the 12th year of King Yeonsan-gun, a group of officials - notably Park Won-jong, Seong Hui-an, Yoo Soon-jeong and Hong Gyeong-ju - plotted against the despotic ruler. They launched their coup on 2 September 1506, deposing the king and replacing him with his half-brother, Grand Prince Jinseong. The king was demoted to prince, and sent into exile, where he died the same year. Consort Jang Nok-su was regarded as the 'femme fatale' that encouraged Yeonsangun's misrule and was beheaded. Yeonsangun's young sons were killed as well.
