Violence permeated much of social life across the vast geographical space of the European, American, Asian and Islamic lands and through the broad sweep of what is often termed the Middle Millennium (roughly 500 to 1500). Focusing on four contexts in which violence occurred across this huge area, the contributors to this volume explore the formation of centralised polities through war and conquest; institution building and ideological expression by these same polities; control of extensive trade networks; and the emergence and dominance of religious ecumenes. Attention is also given to the idea of how theories of violence are relevant to the specific historical circumstances discussed in the volume's chapters. A final section on the depiction of violence, both visual and literary, demonstrates the ubiquity of societal efforts to confront meanings of violence during this longue durée.
