Background of the Early Politics in Yeongnam and the Structure of Saroguk

Through the long-distance trade network and ritual structures of base settlements that were intensively developed in the Yeongnam region in the 2nd century BC, the background of the establishment of the early politics and the method of solidarity were examined. Long-distance trade beyond the Yeongnam region is concentrated in the 2nd century BC, and the bases where foreign trade is active overlap with regions(mainly Daegu, Gyeongsan, and Gyeongju) found in the early days of the clustering of wooden tombs. In some regions, politics that internally united regional units appeared in order to form a socio- economic coalition suitable for logistics distribution, redistribution, cost reduction, and information solidarity amid intensively developed foreign trade in the 2nd century BC. Thus, it is inferred that the clustering of wooden tombs appeared from the time when these early politics reached villages and townships as local political bodies to maintain active foreign trade, iron production, and distribution. In this situation, by linking topographic conditions, traffic routes and literature records, and archaeological data, focusing on Saro-guk, the composition of the euprak and the structure of the country were explained. Around the middle of the 2nd century BC, it is expected that the early Saroguk was established, and it is interpreted that the 6 villages, symbolized as major towns and villages, were united through the conference. Early Saroguk is a device that binds and maintains local communities while showing various forms for each town and village, and the phenomenon of establishing altar-style stone tombs, high- altitude enclosure, standing-ritual structures, and early wooden tombs by base is similar. In addition, the title of ChaChawoong, which was mentioned in early literature records, also weighed on the ideological and religious power base. Given the ritual structure of the settlement base and the power base of the early ruler, it was difficult to sustain the national structure only by pursuing the interests of foreign trade, and it is assumed that even by transforming the traditionally important megalithic monuments and high-altitude enclosure, it led to community cohesion.
