Changes in Tomb Burial Traditions in Southern Gyeonggi Province and the Process of Reorganization of Local Society in Baekje during the 3rd to 5th centuries: Using Social Network Analysis and Geometric Morphometrics(GM)

In Hanseong-period Baekje studies, southern Gyeonggi was understood to be part of Baekje's direct dominion in the late third century, which included the Seoul and Gyeonggi regions. However, the accumulation of excavations in the Seoul and Gyeonggi regions has raised the need to recognize the growth process of early Baekje differently. In addition, the diversity of tombs in the southern Gyeonggi region has been noted, with the continuation and discontinuation of traditional tombs and the transition to and emergence of Baekje-style tombs occurring simultaneously until the fifth century. In other words, it can be assumed that various burial traditions coexisted in the southern Gyeonggi region during the Hanseong period, depending on the lineage of the builders and the way Baekje's provinces were organized. Therefore, this study aims to identify the community composition and relationship changes in the southern Gyeonggi region during the 3rd-5th centuries to understand the changes in the relationship between local tomb-building groups according to Baekje's provincial strategy.
