Myeongjong of Joseon

Myeongjong, personal name Yi Hwan, was the 13th monarch of Joseon. His father was King Jungjong and his mother was Queen Munjeong, the elder sister of Yun Won-hyeong. He ascended to the throne at the age of 11, upon the death of his childless half-brother, King Injong. Since he was too young to govern, his mother became regent.
