The four volumes of the Cambridge History of War were conceived in global terms. The aim was to go beyond a history centred on warfare in Europe, in which the global context emerged solely through the eyes of European exploration, trading, and colonisation. Instead, the volumes would seek to provide the reader with a broader approach to warfare across the world, in which the experiences and trajectories of states and their military systems could be examined and compared. Europe and Europe’s military engagement with the wider world would have a place, but would not be the single point of reference from which global warfare would be seen. This aim was the starting point for Volume III, both as initially conceived by the first editors, John Childs and Arthur Waldron, and then by the current editorial team.
