Deposing Popes and Kings: the Praxis of Tyranny during the Great Western Schism (1378–1417)

Abstract
This essay summarises the evolution of the concept of tyranny from classical antiquity through late medieval Europe, examining its application to both secular and ecclesiastical figures. Beginning with Aristotle’s characterisation of tyranny as unconstitutional rule, the essay explores how classical definitions influenced early Christian thought, particularly through the writings of Isidore of Seville. Isidore’s adaptation of tyranny to ecclesiastical contexts paved the way for later medieval thinkers like John of Salisbury and Bartolus de Sassoferato to articulate theories of illegitimate power in both secular and religious spheres. The essay then delves into the Great Western Schism (1378–1417), during which the papacy was divided between rival claimants, leading to accusations of tyranny against popes and secular rulers alike. Through detailed analysis of historical sources and contemporary accounts, the essay demonstrates how charges of tyranny were leveraged to justify the deposition or elimination of political and religious figures, including Pope Urban VI, King Richard II of England, King Wenceslaus of Germany, and Pope Benedict XIII. I conclude with the case of King Władysław II Jagiełło of Poland. Drawing parallels between these cases, the article highlights common themes found in accusations of tyranny, such as abuse of power, financial mismanagement, refusal of counsel, and religious dissent. By examining the rhetoric and political dynamics surrounding these events, the essay argues that the concept of tyranny served as a powerful tool for legitimising political action and shaping public discourse.
