고려말 東北面 영토개척과 영토의식: 公嶮鎭 두만강북설의 출현 배경

Abstract

Examined in this article is how expansion of territory progressed in the Northeast Realm(“東北面, Dongbuk-myeon”) of Goryo at the end of the dynasty, and how the Goyreo people’s recognition of their own territory enlarged accordingly. Alongside the examination of this issue, their recollection of the so-called “Northeast Nine Fortresses(東北九城)” is also observed, in order to determine exactly when the notion of considering the location of Gongheom-jin(公嶮鎭) to have been 700 ri units above the Duman-gang river line actually began to develop. The Goryeo people considered the location of the ‘9 fortresses in the Northeast’ as part of their territory, and established Gongheom-jin as the borderline. They also believed an old stone tablet which had been considered to have belonged to the Goguryeo era as a tablet that was more recently erected by Yun Gwan(尹瓘) in order to mark the borderline. Later, Gongheom-jin served as a basis for Goryeo’s defense against Ming’s threats to establish Cheolryeong-wi(鐵嶺衛) in the region, and as territory expansion continued, its own location also continued to move northward. Meanwhile, Goryeo, while enlarging its territory, also dealt with the Jurchen tribes. The Aldori(斡都里) faction which was living in the Songhwa-gang river basin relocated to the Duman-gang area and surrendered to Goryeo. Goryeo and Joseon both considered their original habitat as part of their own territories. And as Gongheom-jin and Yun Gwan’s tablet continued to be cited as foundations of territorial defense and preservation, the notion that Gongheom-jin had really always been above the Duman-gang river line began to take shape.
