7세기 전반 삼국의 경계

Abstract

Until now, it has been common to assume that Silla had self-governed to the southwest province of current Gyeonggi as it expanded to the Han river basin in the mid 6th century.
 The theory that considers Silla"s Danghang Castle(党項城) as Dangseong(唐城), which has been taken for granted, was solidified as the understanding formed without clear proof was followed. Also, remains of Danngseong which was valued as basis, are also interpreted according to this premise. Therefore, ‘Silla’s territorial possession in southwest Gyeonggi province theory’ need to be reexamined in full-scale.
 In the early period of the 7th century, Goguryeo and Baekjae were at odds over the Han rive. Also Silla expanded to the Han river along the water system of Namhan river and based on it, Silla westerly encroached the territory of Baekjae. For this reason, the boundary between the two countries was formed centering around the line connecting Gwangju, Yongin, Jinwi, and Jiksan. Gakam-seongm which is attacked and defended between two countries, is assumed to Yongin.
 The remains of Dangseong was built by Baekjae at first and after Silla retained it, was constructed again. Currently, construction method which was confirmed or relics which were excavated cannot support the possession of Silla before the middle of the 7th century.
