Common good and private justice: letters of marque and the utilitas publica in fourteenth-century Marseilles

Political debate, even in medieval Europe, has often centred upon the relationship between individual liberties and the greater good. Fourteenth-century town councils had to think about protecting private property while ensuring the greater public good. The council registers of late medieval Marseilles offer the opportunity for insight into this public–private dichotomy through an examination of the council's decisions to suspend temporarily the execution of letters of marque. In fourteenth-century Marseilles, letters of marque helped citizens gain restitution from foreign debtors through a judicial authorisation to seize foreign assets. The suspensions, justified in the language of the utilitas publica, were declared for two reasons: to protect the integrity of the town's market by ensuring an ample supply of labourers and victuals, and to protect the town's honourable reputation when dignitaries visited. Study of these suspensions illustrates an overarching philosophy in urban government – that the public good must be safeguarded against private advantage.
