Military History of Goryeo

In this episode, we explore the military history of Goryeo, examining how the dynasty built and sustained a sophisticated defense system over nearly five centuries through a centralized army, regional militias, and elite royal guards, while navigating relentless external threats from the Khitans, Jurchens, and eventually the Mongols; the discussion traces Goryeo’s adaptability in warfare, from prolonged resistance campaigns to notable advances in naval power, shipbuilding, and early gunpowder weapons used against pirate incursions, and concludes by reflecting on how prolonged military rule weakened the state, setting the stage for a decisive coup that ended the dynasty and ushered in a new era of Korean martial and political traditions.
