ABSTRACT

Three Kingdoms boundaries in the second half of the 5th century could be confirmed through the analysis of the names of the towns and regions, and the aspects of the war among the three Kingdoms at the end of the 5th century. Goguryeo attacked Silla continuously, but Silla managed to expand its territory in the second half of the 5th century. In 481, Goguryeo attacked Silla to save Baekje. Goguryeo army's axis of attack extended to Chungju, where Goguryeo built a monument. By this, the date of the monument could be traced. The Mosan Fort Battle was fought in 484. The battle site is estimated to be at Gomosung (姑母城) in Mungyeong, not at the Daemosansung (大母山城) in Jincheon. Goguryo army based in Chungju pressed Silla through Gyeripryeong pass (雞立嶺), but It failed because Baekje supported Silla. In 489, Koguryo army again attacked northern boundary of Gwahyun (戈峴) and Hosansug (狐山城) and occupied Sobaeksanmaek (小白山脈) mountain range and hold the territory until the 6th century. Silla advanced to Cheongju area after the victory at Salsu field (薩水之原) in 494. ​​Baekje's boundary reached Cheongju and the west of it. Silla established a fortified base area from which it could immediately advance north in short period of time whenever it wanted to. Baeje fortified its fortresses to prepare against the possible threat by Silla. Through seven battles at the end of the 5th century, the three kingdoms could form their boundaries at Chongju and along the Sobaek mountain range. At Cheongju area, Baekje and Silla formed allies forces, Silla hold Chungju area exclusively. At Usansung (牛山城) battle, Baekje failed to send supporting troops due to the geographic difficulties. After this, there developed schism in the alliance of Silla and Baeje. In the mid-6th century, Silla could maintain the upper hand when the war of the three kingdoms resumed.
