in 1914. In the background, however, the United States remained by far the mightiest manufacturing nation in the world, and Stalin’s Russia was quickly transforming itself into an industrial superpower. Consequently, the dilemma for the revisionist ‘middle’ powers was that they had to expand soon if they were not to be overshadowed by the two continental giants. The dilemma for the status quo middle powers was that in fighting off the German and Japanese challenges, they would most likely weaken themselves as well. The Second World War, for all its ups and downs, essentially confirmed those apprehensions of decline. Despite spectacular early victories, the Axis nations could not in the end succeed against an imbalance of productive resources which was far greater than that of the 1914–18 war. What they did achieve was the eclipse of France and the irretrievable weakening of Britain – before they themselves were overwhelmed by superior force. By 1943, the bipolar world forecast decades earlier had finally arrived, and the military balance had once again caught up with the global distribution of economic resources.
The last two chapters of this book examine the years in which a bipolar world did indeed seem to exist, economically, militarily, and ideologically – and was reflected at the political level by the many crises of the Cold War. The position of the United States and the USSR as powers in a class of their own also appeared to be reinforced by the arrival of nuclear weapons and long-distance delivery systems, which suggested that the strategic as well as the diplomatic landscape was now entirely different from that of 1900, let alone 1800.
And yet the process of rise and fall among the Great Powers – of differentials in growth rates and technological change, leading to shifts in the global economic balances, which in turn gradually impinge upon the political and military balances – had not ceased. Militarily, the United States and the USSR stayed in the forefront as the 1960s gave way to the 1970s and 1980s. Indeed, because they both interpreted international problems in bipolar, and often Manichean, terms, their rivalry has driven them into an ever-escalating arms race which no other powers feel capable of matching. Over the same few decades, however, the global productive balances have been altering faster than ever before. The Third World’s share of total manufacturing output and GNP, depressed to an all-time low in the decade after 1945, has steadily expanded since that time. Europe has recovered from its wartime batterings and, in the form of the European Economic Community, has become the world’s largest trading unit. The People’s Republic of China is leaping forward at an impressive rate. Japan’s postwar economic growth has been so phenomenal that, according to some measures, it recently overtook Russia in total GNP. By contrast, both the American and Russian growth rates have become more sluggish, and their shares of global production and wealth have shrunk dramatically since the 1960s. Leaving aside all the smaller nations, therefore, it is plain that there already exists a multipolar world once more, if one measures the economic indices alone. Given the book’s concern with the interaction between strategy and economics, it seemed appropriate to offer a final (if necessarily speculative) chapter to explore the present disjuncture between the military balances and the productive balances among the Great Powers; and to point to the problems and opportunities facing today’s five large politico-economic ‘power centres’ – China, Japan, the EEC, the Soviet Union and the United States itself – as they grapple with the age-old task of relating national means to national ends. The history of the rise and fall of the Great Powers has in no way come to a full stop.
Since the scope of this book is so large, it is clear that it will be read by different people for different purposes. Some readers will find here what they had hoped for: a broad and yet reasonably detailed survey of Great Power politics over the past five centuries, of the way in which the relative position of each of the leading states has been affected by economic and technological change, and of the constant interaction between strategy and economics, both in periods of peace and in the tests of war. By definition, it does not deal with small powers, nor (usually) with small, bilateral wars. By definition also, the book is heavily Eurocentric, especially in its middle chapters. But that is only natural with such a topic.
To other readers, perhaps especially those political scientists who are now so interested in drawing general rules about ‘world systems’ or the recurrent pattern of wars, this study may offer less than what they desire. To avoid misunderstanding, it ought to be made clear at this point that the book is not dealing with, for example, the theory that major (or ‘systemic’) wars can be related to Kondratieff cycles of economic upturn and downturn. In addition, it is not centrally concerned with general theories about the causes of war, and whether they are likely to be brought about by ‘rising’ or ‘falling’ Great Powers. It is also not a book about theories of empire, and about how imperial control is effected (as is dealt with in Michael Doyle’s recent book Empires), or whether empires contribute to national strength. Finally, it does not propose any general theory about which sorts of society and social/governmental organizations are the most efficient in extracting resources in time of war.
On the other hand, there obviously is a wealth of material in this book for those scholars who wish to make such generalizations (and one of the reasons why there is such an extensive array of notes is to indicate more detailed sources for those readers interested in, say, the financing of wars). But the problem which historians – as opposed to political scientists – have in grappling with general theories is that the evidence of the past is almost always too varied to allow for ‘hard’ scientific conclusions. Thus, while it is true that some wars (e.g. 1939) can be linked to decision-makers’ fears about shifts taking place in the overall power balances, that would not be so useful in explaining the struggles which began in 1776 (American Revolutionary War) or 1792 (French Revolutionary) or 1854 (Crimean War). In the same way, while one could point to Austria-Hungary in 1914 as a good example of a ‘falling’ Great Power helping to trigger off a major war, that still leaves the theorist to deal with the equally critical roles played then by those ‘rising’ Great Powers Germany and Russia. Similarly, any general theory about whether empires pay, or whether imperial control is affected by a measurable ‘power–distance’ ratio, is likely – from the conflicting evidence available – to produce the banal answer sometimes yes, sometimes no.
Nevertheless, if one sets aside a priori theories and simply looks at the historical record of ‘the rise and fall of the Great Powers’ over the past five hundred years, it is clear that some generally valid conclusions can be drawn – while admitting all the time that there may be individual exceptions. For example, there is detectable a causal relationship between the shifts which have occurred over time in the general economic and productive balances and the position occupied by individual powers in the international system. The move in trade flows from the Mediterranean to the Atlantic and northwestern Europe from the sixteenth century onward, or the redistribution in the shares of world manufacturing output away from western Europe in the decades after 1890, are good examples here. In both cases, the economic shifts heralded the rise of new Great Powers which would one day have a decisive impact upon the military/territorial order. This is why the move in the global productive balances toward the ‘Pacific rim’ which has taken place over the past few decades cannot be of interest merely to economists alone.
Similarly, the historical record suggests that there is a very clear connection in the long run between an individual Great Power’s economic rise and fall and its growth and decline as an important military power (or world empire). This, too, is hardly surprising, since it flows from two related facts. The first is that economic resources are necessary to support a large-scale military establishment. The second is that, so far as the international system is concerned, both wealth and power are always relative and should be seen as such. Three hundred years ago, the German mercantilist writer von Hornigk observed that
whether a nation be today mighty and rich or not depends not on the abundance or security of its power and riches, but principally on whether its neighbours possess more or less of it.
In the chapters which follow, this observation will be borne out time and again. The Netherlands in the mid-eighteenth century was richer in absolute terms than a hundred years earlier, but by that stage was much less of a Great Power because
