This study employs John Dollard and colleagues' Frustration-Aggression Hypothesis as a theoretical lens to analyze the pervasive political violence of Shah Abbas I (r. 1588-1629) of the Safavid Empire. It argues that the Shah's violent behaviors—including the suppression of the Qizilbash, the murder of relatives, brutal punishments at court, and aggression towards foreigners—were not merely acts of a tyrannical personality but can be understood as aggressive responses to profound structural and personal frustrations. These frustrations stemmed from internal threats to central authority, external military pressures from the Ottomans and Uzbeks, and personal insecurities rooted in a turbulent youth. Using a historical-analytical method, this interdisciplinary research synthesizes Persian chronicles and European travelogues to trace a causal link between specific failures/frustrations and subsequent aggressive policies. The findings suggest that Shah Abbas's reign presents a compelling historical case study of the frustration-aggression dynamic operating at the level of statecraft, where psychological defense mechanisms became institutionalized as tools of governance. This analysis provides a deeper, multi-causal understanding of Safavid political behavior, moving beyond purely political or military explanations to incorporate psychosocial drivers.
