This sketch of the liveliest issues in postwar diplomatic history would seem to support the view of those who claim that all history is implicated in ideology. The disagreements of diplomatic historians do suggest that political and national passions play an unusually large part in their interpretation of diplomatic history. On the other hand, lack of new techniques does not mean that diplomatic historians are no better at their task than their predecessors were. Some interpretations have been definitively discredited, and signs of convergence have emerged even on such contested topics as the origins of World War I. As the European nations entered the European Union, an effort was made to write a history textbook on which historians from various countries could agree. Although it relied upon a certain amount of euphemism (the German invasion of Belgium in 1914 was referred to as a “transit” of their troops), it did show that, even in this controversial field, some consensus can be achieved. Economic history
History and economics were once closely related. Adam Smith, Thomas Malthus, and Karl Marx were all political economists who incorporated historical data into their analyses. A historical school of economics developed in Germany in the late 19th century and was associated with figures such as Gustav von Schmoller (1838–1917). Reacting against the free-trade doctrines of British economists (which would have prevented Germany from protecting its industries until they were strong enough to compete), the historical economists argued that there are no universally valid economic laws and that each country should define its own economic path.

A similar interest in historical development was shown by institutional economists such as the eccentric genius Thorstein Veblen (1857–1929). The American Historical Association and the American Economic Association were founded together and did not separate for several years; it was common in American colleges for historians and economists to be in the same department. From the turn of the 20th century, however, the two disciplines pursued radically different paths. While economists developed ever-more-elaborate mathematical models, historians remained mired in the messy details of the world.
While this division between the disciplines occurred, much good work was done on the workings of preindustrial economies and on the question of why serfdom was introduced in Poland and Russia just as it was dying out in western Europe. In several countries, cost-of-living indexes that covered several centuries were computed. Although these estimates were imperfect (as they still are), they illuminated such famous questions as the causes of the French Revolution and the condition of the working class during the Industrial Revolution in England. The French historian Camille-Ernest Labrousse (1895–1988) showed that in France during the period from 1778 to 1789, a long recession was exacerbated by high bread prices and eventually the bankruptcy of the crown. Believers in “deeper” causes of the revolution treated this conjunction as only a trigger, but since many popular disturbances in the first years of the revolution were bread riots that turned to political violence, it is hard to avoid the conclusion that the history of the period would have been quite different under different economic conditions.
Economic history in Britain has always been influenced by the fact that it was the first country to undergo an industrial revolution. In the aftermath of World War II, economic planners looked to Britain for an example of how countries in the developing world might achieve the same transformation. The American economist and political theorist Walt Whitman Rostow (1916–2003), in Stages of Economic Growth (1960), attempted a general theory of how economies industrialize. His six-stage model did not gain general acceptance, but he did raise the issue of long-term economic development, which directed some economists, at least, toward history.
The proposition that the Industrial Revolution was a good thing was universally maintained by historians who were sympathetic to capitalism. Socialist historians, on the other hand, judged it more ambivalently. For orthodox Marxists, only industrialized countries would create a proletariat strong enough to expropriate the means of production, and the enormous productive power of industrial society would be the basis of the “kingdom of plenty” under communism. At the same time, they emphasized the arbitrary way in which industrialization was carried out and the suffering of the workers. Because much of the evidence for the suffering of the workers was in fact anecdotal, a number of economic historians tried to determine whether their standard of living actually declined. Although wage rates were known, industrial workers were often laid off, so their annual income was not a simple multiple of their average wage. Despite the difficulties of the inevitably controversial calculations, it seems to be true that workers’ standard of living at least did not decline, and may even have improved slightly, before 1850. This conclusion did not resolve the issue of their suffering, however, since workers also endured noneconomic losses. The matter continues to be a concern for social and economic historians.
The distinctive feature of the American economy was slavery. One overriding issue for economic historians has been whether slavery was inherently inefficient as well as inhumane and thus whether it might have disappeared through sheer unprofitability had it not been legally abolished. This is an extremely complicated question. An answer requires not only large amounts of data but also data about almost all aspects of the American economy. To see how the data fitted together, historians after World War II drew upon macroeconomic theory, which showed how various inputs affect the gross national product.
There was, however, a further problem: how did the productivity of slave labour compare with the hypothetical product of free labour applied to the same land? In other words, if there had been no slavery, would Southern agriculture have been more (or less) profitable? One attempt to resolve this counterfactual question was offered in Railroads and American Economic Growth: Essays in Economic History (1964) by Robert Fogel, an American economist who shared the Nobel Prize for Economics with Douglass C. North in 1993. Fogel tested the claim that railroads were of fundamental importance in American economic development by constructing a model of the American economy without railroads. The model made some simplifying assumptions: passenger travel was ignored, and since canals were the principal alternatives to railroads, the part of the United States west of the continental divide was also left out. With these provisos, the model showed that the importance of railroads had been exaggerated, because in 1890 the gross national product without railroads would have reached the same level as the actual one.
In Time on the Cross: The Economics of American Negro Slavery (1974), Fogel and his colleague Stanley Engerman addressed the issue of the profitability of slavery, using the methods Fogel had developed in his earlier study. Using evidence only from the last decade of American slavery, they argued that the system was not only profitable but more profitable than free labour would have been. The response to their work illustrates many of the accomplishments and pitfalls of what came to be called cliometrics, the application of statistical analysis to the study of history. It sold more than 20,000 copies, a large number for a scholarly book; it shared the Bancroft Prize for history; and it was the subject of stories and bemused reviews in the popular press. However, because it adopted the French custom of segregating tables and other statistical matter in a second volume—which appeared not simultaneously but several months later—the initial reviewers had access only to the conclusions and the supporting textual arguments. These initial reviews were generally respectful, but when the second volume appeared, many cliometricians attacked its statistical analysis. Other scholars assailed the work for everything from insufficient indignation about the evils of slavery to improper attributions of classical profit-maximizing economic motives to participants in an institution that Thomas Jefferson characterized as “a continuous exercise of the most boisterous of passions.” (Fogel and Engerman argued that slaves were rarely whipped, because whipping would have diminished their capacity for work.)
