고고자료로 본 3~6세기 고성지역 정치체의 성장과 변천

Abstract

Through archaeological data, this paper attempted to examine the process of transitional changes according to changes in the spatial domain of political bodies originating and growing in the Goseong area from the 3rd to the mid-to-late 6th century. Since about 1,800 years ago, the sea level in the Goseong area has risen again, making it possible to call port through Goseong Bay, and in the Goseongcheon alluvial plain area, freshwater lakes were formed, securing temporary land. Dongoe-dong Shell Mound is a central settlement formed around the 3rd and 4th centuries in Goseong Bay, and it can be seen that contemporary people divided the space according to functions such as squares, residences, steel facilities, and shell mounds. From the relics identified in the nearby Goseong-eup Fortress Site, the Samhan people who formed the Dongoe-dong Shell Mound were able to grow into a dominant group that integrated the Goseong Basin through active external trade with Nakrang in the north and Guju groups in the Japanese archipelago. In the 4th century, the remote trading system between politicians in the Yeongnam region, such as the expulsion of Chinese counties and prefectures and the growth of Geumgwan Gaya, will face major changes among diversified centers. By the 5th century, the trading system with neighboring countries was reorganized again, and with the emergence of central tombs, the formation of a resinous relationship in which a specific political body took the dominant position became clear. Foreign relics excavated from the ancient tomb group in the center of Goseong area are changed around the metalwork and harness for dressing in the dynamics of the surrounding forces, and at the same time, their identity and orientation are projected. In particular, Manlimsan Saturn, built around the early 6th century, can be seen as a structure that reflects the ruling control of Sogaya and the best civil engineering technology, and as a robustness of Sogaya politics.
