ABSTRACTI contextualize and interpret the distinction in Hobbes’ Leviathan between the capacities of the sovereign and show its importance for contemporary debates on the nature of Hobbesian sovereignty. Hobbes distinguishes between actions the sovereign does on personal title, and actions he undertakes in a political capacity. I argue that, like royalists defending King Charles I before and during the English civil war, he maintains that the highest magistrate is sovereign in both his natural and political capacities because the capacities are (...) inseparable, though district. This position goes back to the treatment of Calvin’s Case by Francis Bacon and Edward Coke and has further precedents in medieval English constitutional thought. An important reason for Hobbes to include this doctrine in Leviathan, I suggest, is to provide a response to parliamentarians who employed the sovereign’s multiple capacities to justify armed resistance against the king. I show the relevance of this contextualization by intervening in two recent debates, regarding the possibility of constitutionalist limitations on the actions of the Hobbesian sovereign and regarding whether sovereignty is held by the commonwealth or by the person of the sovereign.
