This volume traces the logic of urban political conflict in late medieval Europe's most heavily urbanized regions, Italy and the Southern Low Countries. The fourteenth and fifteenth centuries are often associated with the increasing consolidation of states, but at the same time they also saw high levels of political conflict and revolt in cities that themselves were a lasting heritage of this period. In often radically different ways, conflict constituted a crucial part of political life in the six cities studied for this book: Bologna, Florence, and Verona, as well as Liege, Lille, and Tournai. The Logic of Political Conflict in Medieval Cities argues that such conflicts, rather than subverting ordinary political life, were essential features of the political systems that developed in cities. Conflicts were embedded in a polycentric political order characterized by multiple political units and bases of organization, ranging from guilds to external agencies. In this multi-faceted and shifting context, late medieval city dwellers developed particular strategies of legitimating conflict, diverse modes of behaviour, and various forms of association through which conflict could be addressed. At the same time, different configurations of these political units gave rise to specific systems of conflict which varied from city to city. Across all these cities, conflict lay at the basis of a distinct form of political organization-and represents the nodal point around which this political and social history of cities is written.

The complexity of the interplay and relationships over various borders in medieval Europe is here fully teased out. The processes by which ideas, objects, texts and political thought and experience moved across boundaries in the Middle Ages form the focus of this book, which also seeks to reassess the nature of the boundaries themselves; it thus appropriately reflects a major theme of Dr Malcolm Vale's work, which the essays collected here honour. They suggest ways of breaking down established historiographical paradigms of Europe as a set of distinct polities, achieving a more nuanced picture in which people and objects were constantly moving, and challenging previous conceptions of units and borders. The first section examines the construction of boundaries and units in the later Middle Ages, via topics ranging from linguistic units to social stratifications, and geographically from the Netherlands and Scotland to Gascony and the Iberian peninsula; it reveals how much the relationship between exchange and boundaries was reciprocal. The second section considers the mechanisms by which it took place, from West Africa to Italy and Flanders, and discusses the actual exchange of people, texts, and unusual artefacts. Overall, the essays bear witness to the constant interplay and interconnections throughout medieval Europe and beyond.
