Assembly is a central feature of the European political process between the demise of the Roman Empire and the rise of the bureaucratic state in the twelfth and thirteenth centuries. Historians have often neglected the crucial rule of political assemblies in their own right, concentrating instead on exceptional or extraordinary attention-catching events which occurred at assemblies. Earlier generations of scholars tried to discern in such assemblies the forerunners of later medieval parliaments and other forms of representative government. By contrast, the contributors to this volume present medieval assemblies in their own terms. Were political assemblies in the earlier Middle Ages convened to confirm decisions already taken elsewhere or were they genuinely deliberative? How, if at all, did political assemblies create consensus? At what level(s) of the political and administrative hierarchy were assemblies held, who attended such gatherings, how were they conducted, and where were they held? The main focus is on assemblies of emperors, kings, and princes, and on those of townsfolk, those some more local assemblies are also discussed. The over-arching thematic structure relates to the purposes of assemblies and how they worked, their practical and ritual or symbolic aspects, and the degree to which they were stage-managed, and by whom. The contributors bring archaeological, as well as historical, evidence to bear and present a range of geographical, political and historiographical approaches and traditions. The papers offer a coherent thread of analysis running from the immediate successor states of the Roman Empire to the High Middle Ages and range in geographic coverage from Scandinavia to Catalonia, and from Ireland to Russia.
