Koryo kingdom's final decline

1390

The Korean dynasty, nominally still ruling from Gaeseong, was exhausted by Japanese pirate raids, Red Turban incursions, and factional court politics that had paralyzed decision-making. Yi Seonggye's rise to power was made inevitable by this military and institutional exhaustion. Two years later the Joseon dynasty would replace the five-century-old Koryo regime.
