趙光祖
Jungjong of Joseon, who succeeded Yeonsangun, again embraced Sarim scholars as a means to check powers of Hungu ministers who put him on the throne and thus wielded power that virtually superseded Jungjong. Again, Sarim scholars led by Jo Gwang-jo used Three Offices as power base to challenge Hungu ministers and launch a series of reforms. However, Jungjong was estranged from Jo Gwang-jo due to radical nature of his reforms and slander of the Hungu faction, which led to Third Literati Purge of 1519.
