『사기』로 본 고대의 요동

Abstract

The location of the Liaodong (遼東) in ancient China was different from that of today. The Liaodong at the time was a major indicator of the western boundary of Old Joseon (古朝鮮), the first Korean nation. According to literature including Sagi (史記), Liaodong in ancient was a place name first used to point to the Far East of China. However, over time, it has also apply to name of the administrative district and princely states in China. Example of the former both includes Liadong-gun (遼東郡), an administrative district established after the Yan (燕) defeated Dongho (東胡) and Old Joseon, built their Great Wall, and is Liaodong-gun, an administrative district established during the Qin (秦) and Western Han (西漢) period. Example of the latter was Liaodong-guk (遼東國), an princely states established by dividing the land of the former Yan in the early Han Dynasty.
 The Liaodong before invasion Dongho and Old Joseon by Jingae (秦蓋) (approximately BC 300) seem to have pointed to outside the eastern border of the Yan, that is, the area between the Chisu (治水) River (currently Yeongjeongha 永定河) and the Gosu 沽水) River (currently Jobaekha 潮白河). After the invasion of Jingae, it went beyond the region and pointed to the east part of Yusu (濡水) River (currently Nanha 灤河). The Liaodong-gun which was established during the Jingae period, the Liaodong-gun which was established during the Qin Dynasty, and Liaodong-guk which was established during the Western Han were geographically overlapped on the same region. Therefore, we argue that the Liaodong from the ancient Yan to the Western Han period was a region limited to the east part of the lower stream of Yusu (濡水) River (currently Nanha 灤河).
