신라 관성군의 공간 구조와 관산성 전투

Abstract

This paper systematically examined the spatial structure of Silla's Gwanseong-gun County, where the Battle of Gwansanseong Fortress was fought in 554 and restored the approximate course of the Battle of Gwansanseong based on this. Gwanseong-gun was composed of a direct area and two affiliated prefectures, and the central hill fortress of Gwanseong-gun was probably Seosanseong, with the interior of the Okcheon basin as its core area. It is also believed that Samseongsanseong Fortress was built across the Geumgucheon River to defend the mouth of the basin. On the other hand, the legend that Gwanseonghyang is the old site of the county would be difficult to apply, at least during the Silla period. The Okcheon area would have been important at the time because it was the route of a straight road from Gongju and Buyeo to Gyeongju. However, the roads from Gongju and Buyeo to Okcheon are different, and it may have been more efficient to travel from Buyeo via Jinsan and Chubu rather than Daejeon. The Battle of Gwansanseong is believed to have taken place at the end of 554. Prior to this, Baekje first attacked and captured Jinsung, that is Jinsan, which had been occupied by Silla. The main leader of the attack on Gwansanseong was the Baekje prince Yeo Chang, who built a fortress in Gutamora before attacking Gwansanseong and it is worth considering the possibility that it is related to Seongchisanseong. This was joined by troops from Baekje's eastern army, as well as the Japanese and Gaya armies, and they captured Gwansanseong around December 9th. It was shortly thereafter that King Seong departed to pay his respects to the prince, and the Silla forces led by Kim Muryeok may have entered from Samnyeonsanseong, that is Boeun, and ambushed and killed him.
