Intelligence has never been a more important factor in international affairs than it is today. Since the end of the Second World War, vast intelligence bureaucracies have emerged to play an increasingly important role in the making of national policy within all major states. One of the biggest problems within the contemporary thinking about intelligence and international relations is a lack of historical context. Observers routinely comment on the challenges facing intelligence communities without reflecting on the historical forces that have shaped these communities over the past two centuries. As presented in this volume, new perspectives on the evolution of intelligence services and intelligence practice over the past 200 years can only enrich ongoing debates over how best to reform national intelligence structures.
