Myeongjong of Joseon, Ruler of Korea (d. 1567)
Myeongjong of Joseon (3 July 1534 – 3 August 1567, r. 1545–1567) was the 13th king of the Joseon Dynasty of Korea. He was the second son of Jungjong, and his mother was Queen Munjeong, who was Jungjong's third queen.
He became king in 1545 at the age of 12 following the death of his half-brother, Injong. Since he was too young to rule the kingdom, Queen Munjeong governed the nation in his name.
