King Seonjo
Fourteenth king of Joseon; fled to Uiju and asked Ming for help
He brought the sarim into government in large numbers, but in 1575 they split into Easterners and Westerners, and the Jeong Yeo-rip treason case of 1589 led to the Gichuk Purge. When the Imjin War broke out in 1592 he fled Hanyang via Pyongyang to Uiju. During the war he set up the Military Training Command, and he ordered Heo Jun to compile the Dongui bogam.
