고분자료로 본 삼국시대 성주지역의 정치적 성격

Abstract

Seongju Area has been widely known as the territory of Seongsan Gaya written in 『the Stories of the Three Kingdoms』. So the ancient tumulus have been considered to belong to Seonsan Gaya. But after series of archaeological excavations, not only the tomb structure and the plan features but also retrieved artefacts are similar to those of tombs of Silla Kingdom: The ratio of the length to width in tomb chamber is 3:1 in case of Siila tombs and tombs in Seongju area. Instead that of tombs from Daegaya at Goryeong area is 5:1. The tomb type with vertical access in Seongju is identical to that of Naedang-dong and Bisnadong at Daegu area. In addition the retrieved artefacts excavated from the tombs in Seongju area are similar to those from Silla tombs. Potteries from tombs in Seongju are also similar to those of Silla tombs both in kinds and in types alothough there are some regional diversities in potteries from Seongju area. Some archaeologists have categorized the unique features of potteries from Seongju area as the Seongju type pottery, which is a variety of Silla potteries. The diadems from Seongju area and its ornamental artefacts are thought to be prestige goods of Silla style distributed by the central government of Silla Kingdom to a local political entity. Therefore the tomb information reveals that the Seongju area belonged to the cultural sphere of Silla Kingdom during the Three Kingdoms Period and the various potteries from the tombs in Seongju imply that Seongju area had been under the influence of Silla Kingdom or it had been annexed to Silla Kingdom around second part of the fourth century AD along with Daegu area.
