The essays in this volume offer a state-of-the-art analysis of a heretofore somewhat neglected part of financial history: the way in which urban governments in Western Europe during the late Middle Ages and early Modern Times handled the public debts their cities were confronted with. The technical aspects of the sale of annuities (renten, rentes) may have already been abundantly studied, but the links with social and political history still needed to be tackled. Who bought these annuities and thus participated in sharing the burden and profits which were likely to arise from them? What were their motives? How did the obvious links with urban elites work? And, perhaps most significantly, how did these occasional sales evolve into a structural way of linking financially important private persons with public finances, in the context both of cities and of growing states, since often the cities needed the money on a short-term basis in order to accomplish their own financial obligations toward 'the state'. Participants in the colloquium where a large number of the essays were first presented represent in the first place the urban strongholds of Europe in the period under scrutiny: the Low Countries and Northern and Central Italy, but the Swiss cities, the cities of Aragon, London and papal Rome are also considered.
