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 second year of King Myeongjong's reign).

The initial event was a graffiti posted on a wall at the Yangjae stage Station (now Yangjae-dong, Seocho District, Seoul). This was a false notice, posted on the order of Yun Won-hyeong, to defame himself and his relatives.

"A female leader at the top, treacherous ministers Li Ji 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 slander was used by the SoYun faction as a pretext to remove its political opponents, starting from Prince Bong-seong (, 1528–1547). This purge was enlarged to all the survivors of the DaeYun faction.
