Leadership in the Emergent Baekje State: State Formation in Central-Western Korea (ca. 200–400 CE)

Abstract

The process of state formation is a social phenomenon closely connected with a polity’s external relationships. During peer–polity interactions, polities undergo social reorganization as they mutually influence each other. This study examines this process and argues that in central-western Korea, around 200–400 CE, hostile interactions among multiple polities weakened the power of ingroup members to level social differences and increased social complexity. When confronted with unfriendly outgroups, potential rulers could assume different social roles (e.g., diplomat, war leader, or trader) and utilize new social threats to demand and legitimize higher social status. Archaeological data from central-western Korea illustrate the community’s efforts to build a defense system and prepare for war. Autonomous agricultural communities rapidly realigned into a state system in response to external threats, presumably from historically documented hostile groups such as the Lelang commandery and Goguryeo. The decision to oppose neighboring polities likely enhanced the leaders’ ability to consolidate power, while the rulers of the Baekje (also spelled “Paekche”) state could employ various other means for self-aggrandizement throughout its history.
