This paper is concerned with the old economic history which developed in Britain before World War I. It would be more appropriate to call it “the very old economic history,” to distinguish it from “the old economic history” of the inter-war years and beyond, and “the new economic history,” a fragile offshoot of American enterprise only now being propagated successfully. To avoid terminological clumsiness, and to indicate clearly that the history of economic history in Britain divides into three stages, I will refer throughout this paper to Economic History I (EH I), Economic History II (EH II) and Economic History III (EH III), stages which divide chronologically at 1910–1920 and 1960–1970, and which are characterized by quite distinctive methodological features. My particular aim will be to show that EH I seems to the economist, and to the new economic historian, to be modern in content and method compared with EH II. In particular EH I had a major interest in the conditions of freedom and restraint, especially those embodied in legal institutions controlling property rights, which limited individual economic action, and devoted much effort to investigating the origins of property rights and the development of custom and law as they affected property rights. EH I, also, was more strongly motivated than EH II, both because of a belief in the power of “the historical method” for the understanding and analysis of social processes, and of participation in the great socio-economic debates of the day, especially that which attempted to define the role of the state in economic life. In contrast, EH II seems to have had no particular methodological bias, and, although often politically motivated, was not involved in contemporary debate or in the determination of current policy.
