One of the defining controversies in the field of economic history in the past 35 years is the Brenner debate. Robert Brenner published "Agrarian Class Structure and Economic Development in Pre-Industrial Europe" in Past and Present in 1976 (link) and "The Agrarian Roots of European Capitalism" in 1982. In between these publications (and following) there was a rush of substantive responses from leading economic historians, including M. M. Postan and Emmanuel Le Roy Ladurie. (Many of the most significant articles are collected in Aston and Philpin's The Brenner Debate: Agrarian Class Structure and Economic Development in Pre-industrial Europe.) Brenner's theories injected important new impetus into the old question: what led to the advent of capitalism? (Maurice Dobb had stimulated a similar burst of scholarship on this topic with his 1963 Studies In The Development Of Capitalism (link). Brenner's discussion of the Dobb debate can be found in his essay, "Dobb on the transition from feudalism to capitalism" here.)
The core issue of the debate is large and important: what were the social factors that brought about the major economic transformations of the European economy since the decline of feudalism? Feudalism was taken to be a stagnant economic system; but in the sixteenth century things began to change. There was something of an agricultural revolution in England, with technological innovation, changes of cropping systems, and significant increase in land productivity. There were the beginnings of manufacture, leading eventually to water- and steam-powered machines. There was a population shift from the countryside to towns and cities. There was industrial revolution. (Marx describes much of this process in Capital; here's an earlier post of his concept of "primitive accumulation.") So what were the large social factors that caused this widespread process of social and economic change? What propelled these dramatic changes of economic structure?
The great economic historian M. M. Postan offered a simple theory: “Behind most economic trends in the middle ages, above all behind the advancing and retreating land settlement, it is possible to discern the inexorable effects of rising and declining population” (Medieval Economy and Society: An Economic History of Britain in the Middle Ages, p. 72). Against this view, Brenner writes: "Under different property structures and different balances of power, similar demographic or commercial trends, with their associated patterns of factor prices, presented very different opportunities and dangers and thus evoked disparate responses, with diverse consequences for the economy as a whole. Indeed, . . . under different property structures and balances of class forces . . . precisely the same demographic and commercial trends yielded widely divergent results" (Brenner 1982:16-17). Key to Brenner's argument is the fact that agricultural change was substantially different in England and France; so he insists that an adequate causal explanation must identify a factor that varies similarly.
From the distance of several decades, the dividing lines of the Brenner debate are pretty clear. One school of thought (Postan, Ladurie) attempts to explain the economic transformations described here in terms of facts about population, while the other (Brenner's) argues that the central causal factors have to do with social institutions (social-property relations and institutions of political power). The demographic theory focuses its attention on the factors that influenced population growth, including disease; the social institutions theory focuses attention on the institutional framework within which economic actors (lords, peasants, capitalist farmers) pursue their goals. The one is akin to a biological or ecological theory, emphasizing common and universal demographic forces; the other is a social theory, emphasizing contingency and variation across social space.
A voice that doesn't come into the debate directly but that is highly relevant is that of Douglass North. His book (with Robert Paul Thomas), The Rise of the Western World: A New Economic History, offers a theory of modern economic development that falls within the category of "social institutional theory" rather than demographic theory. But whereas Brenner finds primary causal importance in the institutions that define local class relations (a Marxian idea), North argues that property relations that create the right kinds of incentives will stimulate rapid economic growth (a Smithian idea). And North finds that this is the innovation that took place in England in the early modern period. It was the creation of capitalist property relations that stimulated economic growth.
This schematic representation of the strands of argument in the Brenner debate suggests competing causal diagrams:
- population growth => economic activity => sustained economic growth (Postan)
- weak peasant farmers, strong capitalist farmers => enclosure and farming innovations => rapid agricultural growth (Brenner)
- enhanced protections of property rights => incentive for profitable activity => sustained economic growth (North)
Not all the heat of this debate derives from a polemic between a neo-Marxist theorist and the Malthusians; there is also a significant disagreement between Brenner and another important Marxist economic historian, Guy Bois. Bois' Crisis of Feudalism appeared in 1976 -- the same year as Brenner's first paper in the debate. The crisis to which Bois refers is an analogy with a classic Marxist claim about capitalism: where Marx discerned a crisis in capitalism deriving from the falling rate of profit, Bois found a crisis in feudalism deriving from a falling rate of feudal levy. (Here is an interesting review by Chris Harman of another of Bois' books, The Transformation of the Year One Thousand: The Village of Lournard from Antiquity to Feudalism.) Bois criticizes Brenner's account for being excessively theory-driven. He argues that Brenner begins with a commitment to class struggle as a fundamental explanation, and then forces the facts of French and English rural life into this framework. Better, he argues, to let the complexity of the historical situations emerge through careful evaluation of the evidence. "Brenner's thought is, in fact, arranged around a single principle: theoretical generalization always precedes direct examination of historical source material" (Aston and Philpin, 110). And Bois argues that the evidence will suggest that it is the declining feudal levy rather than the capacity for resistance by French peasants that best explains the course of events in France.
In short, one important consequence of the Brenner debate was the renewed focus it placed on the question of social causation. Brenner and the other participants expended a great deal of effort in developing theories of the causal mechanisms that led to economic change in this period. And in hindsight, it appears that a lot of the energy in the debates stemmed from the false presupposition that it should be possible to identify a single master factor that explained these large changes in economic development. But this no longer seems supportable. Rather, historians are now much more willing to recognize the plurality of causes at work and the geographical differentiation that is inherent in almost every large historical process. So the advice that Bois extends -- don't let your large theory get in the way of detailed historical research -- appears to be good counsel.
