고려말 왜구의 섬 침략과 군사적 대응

Abstract

This study explores Japanese pirates with an emphasis on maritime islands. First of all, the distribution pattern and characteristics of the islands invaded by Japanese pirates were briefly mentioned. At that time, large islands close to the land, such as Geoje Island and Jindo Island, were temporarily moved inland measures(僑郡). Referring to this, the situation of the islands in the far sea was poor, and some would have fallen into ‘the den of Japanese pirates’. In addition, the trend of Japanese pirates invasion and Goryeo's military response over time was examined, and the military activities of Japanese pirates and Goryeo surrounding the island were considered. The Japanese pirates moored their ships on various islands, turning these into launch points for raids on nearby coastal and inland communities. Islands that functioned as anchorings and hideouts for the Japanese pirates included Gyodongdo, Jayeondo and Deokjeokdo in Yanggwangdo, along with Yeonhwado, Yokjido and Chuksando in Gyeongsangdo, plus Galdo and Gunsando in Jeollado. Facing these persistent anchorings and invasions, the Goryeo government began conducting search operations in 1378 (the fourth year of King U’s reign) targeting these islands. Through these proactive military activities, Goryeo’s navy incrementally secured maritime dominance and, recognizing the military strategic value of the islands, established naval bases on several of them.
