신라의 浿江 지역 진출과 서북 島嶼의 지배

Abstract

As a provincial county in Silla, it was possible to check the geographical value and geopolitical implications of Hwanghae-do region and surrounding islands. The Hwanghae-do region and northwestern islands began to be located within the region of local rule in the mid- to late Silla period, and were the strategic points of faithfully performing multi-purpose functions as an outpost of Balhae control and a forward base for foreign trade. Paegangjin region was located on the geopolitical fault line after the formation of Balhae, which required a precise response. Silla's aggressive push to install the steel rods was a mixed factor behind the backdrop, with the distribution of fertile plains areas and the presence of iron ore deposits being the main factors in the implementation of the policy. Against this backdrop, the Paegangjin was the establishment of a military hub at the same time as the strengthening of regional rule Silla conducted on Hwanghae-do region near the border of Balhae. Local county prefectures in the Hwanghae-do and northwestern islands symbolized Silla's strengthening of its control over the islands, and the purpose of operating facilities, such as ranches, was based on the main point or site of the Trans-West Sea route, and performed its management functions. Hwanghae-do and Hanju areas, where a strong earthquake was installed, embraced the newly formed social and economic order along transportation and trade routes, leading to the emergence of fast-growing local forces such as Namcheon-gun and Pyochon-hyun, while maintaining their independence based on the order and leading the social change.
