Jungjong of Joseon

Jungjong was installed as king after the overthrow of his half-brother Yeonsangun. His reign began with promises of reform but was soon dominated by factional struggles.

Jungjong's reign saw the Third Literati Purge, in which Sarim scholars who attempted to implement reforms were purged by the Hungu faction. This set back reform efforts and deepened factional divisions.

After Jungjong's death, his wife Queen Munjeong became regent for their young son Myeongjong. Her regency continued the factional conflicts that had marked Jungjong's reign.
