買肖城 전투와 羅唐戰爭의 종결 ― 『三國史記』 신라본기 675년 2월 기사의 분석 ―

Abstract

Examined in this article are certain issues associated with the ending of the Shilla-Dang war. I tried to reevaluate the issues from a perspective different than before. The February 675 entry of Samguk Sagi(三國史記) portrays how the war ended. This is actually a reedited version of what was written in Shin-Dangseo(新唐書), which neglected to record the Maecho-seong(買肖城) fortress battle and described as if battles continued afterwards. But all the battles recorded here clearly took place before the Maecho-seong battle which broke out in September, and the war itself definitely ended when the status of Shilla king Munmu-wang was reinstated after this particular battle. This Maecho-seong fortress seems to have been the Sugok-seong(水谷城) fortress, which was located upon a strategically important traffic spot leading to the Pyeong’yang area. After Shilla lost region above the Daegok-seong(大谷城) fortress, it tried to secure Maecho-seong but unfortunately failed. As a result, Shilla’s northern borderline was established below the Daegok-seong fortress, and during the reign of King Hyoso-wang, fortresses were built in regions such as Gaeseong(開城) and Wujam(牛岑). Samguk Sagi described the events at the time as if Shilla was able to establish local units right up to “the Southern borderline of Goguryeo(高句麗 南境)” during the war. But such record should be understood as a description of Unified Shilla’s nine Ju units (“九州”) which were established after the war, reflecting the fact that Shilla’s territory under the Daedong-gang river line was authorized by Dang, during Shilla King Seongdeok-wang’s reign.
