Yangjae Station Graffiti Incident

The Yangjae Station Graffiti Incident was one of the many political purges that occurred in Korea during the Joseon period. It is also known as the Jeongmi Sahwa, where Jeongmi refers to name of the year 1547.
The initial event was a graffiti posted on a wall at the Yangjae stage Station. This was a notice, posted on the order of Yun Wŏnhyŏng, to defame himself and his relatives.
"A female leader at the top, treacherous ministers Li Gi and others at bottom. The country is about to perish, but we just wait and see. Isn't that scary? 女主執政于上, 奸臣李芑等弄權於下, 國之將亡, 可立而待。豈不寒心哉?"
This followed the Eulsa purge with the graffiti signalling to Li Gi and Queen Munjeong that the Eulsa purge had been insufficient in getting rid of the DaeYun faction. Hence, the graffiti was used by the SoYun faction as a basis for removing its political opponents, starting from Prince Bong-seong. This purge was enlarged to all the survivors of the DaeYun faction.
