In recent years military history has moved out of its specialized ghetto and has come to be regarded as central to the mainstream study of the past. The concepts of a "military revolution" (consisting of the emergence of large infantry-based armies in early-modern Europe, the use of potent gunpowder weapons, and the rapid escalation of war costs) are now seen to have had far-reaching political and social consequences for European society. Indeed, war itself is now seen as a major engine of state development during this period. The essays in this volume set out to demonstrate the integration of military history with the broader concerns of historians. They also suggest that the military history of the Middle Ages was more dynamic than is often recognized, and that the military revolution needs to be interpreted by placing it in the context of rapid socio-political transformation.
