Goryeo military regime
Kaesong, North KoreaIn 1170, a group of army officers led by Jeong Jung-bu, Yi Ui-bang and Yi Go launched a coup d'état and succeeded. King Uijong went into exile and King Myeongjong was placed on the throne. Effective power, however, lay with a succession of generals who used an elite guard unit known as the Tobang to control the throne: military rule of Goryeo had begun. In 1179, the young general Gyeong Dae-seung rose to power and began an attempt to restore the full power of the monarch and purge the corruption of the state.
