Archaeological Implications of the Pottery that Represents Prestige in the Northwestern Region from Maribgan Era of Silla Kingdom, Focus on the Tube Shaped Pottery Stand

In the mid-5th century, relations between the central and local governments of Silla were established through award for goldsmith's ornaments. On the other hand, it is presumed that pottery functioned as a prestige item in local areas. Among them, the special properties of the tube shaped pottery stand(筒形器臺) have been verified through previous research. However, if it is limited to Silla, it did not receive much attention. In particular, the tube shaped pottery stand of provinces of Silla were considered to be suitable as research subjects for local areas of Silla, because they differed from the tube shaped pottery stand of the central region in terms of morphological characteristics and developmental patterns, but in reality, they received no attention at all. It is interesting that the tube shaped pottery stand with vertical line band decorations found mainly in the northwestern region of Silla is a characteristic that appears mainly in Daegaya, but not in central Silla. Paying attention to these facts, we examined Silla and Gaya as a whole. As a result, Silla's vertical line band decorations appeared almost at the same time as those in the Gaya region. And it was confirmed that the vertical line band decorations spread from the northwestern region of Silla starting in the mid-5th century. Judging from the quantity of excavated goods and the existence of production facilities, the center can be said to be Uiseong(義城), and there is a confirmed tendency toward three directions: Baekje, Daegaya, and the central part(east coast) of Silla. The vertical line band decorations in the northwestern region of Silla are characterized by bean-shaped patterns(豆粒文), and the possibility of exchanges with Gaya is assumed through the burial ritual method and the presence of the jar tube part(壺筒部). In addition, it was only unearthed in the ancient tombs with a high and large mound(高塚古墳) that could be considered stronghold areas in the northwest of Silla. Through these clues, the hierarchical relationships formed in the region at that time will be revealed. Meanwhile, in the exchanges with the central and coastal regions of Silla, it was confirmed that direct exchanges took place with small and medium-sized groups rather than with local strongholds. Therefore, it can be observed that there were various forms of exchange between local groups in Silla. In this way, the tube shaped pottery stand is an artifact that comprehensively reflects the multi-layered hierarchical relationship between local groups in the northwestern region of Silla during the Maripgan period centered around Uiseong, and reflects the appearance of the local organization that was naturally formed at the time. This needs to be given attention in order to understand how Silla governed the provinces in the early 6th century.
