�� Marxist economists are not always renowned for their methodological subtlety, sometimes adhering to a form of simplistic instrumentalism— whatever serves the interests of “the working class” is by definition correct and so forth. However, one Russian/Ukrainian economist who is usually thought of as being in some sense a Marxist—Mikhail Ivanovich Tugan-Baranovsky (1865–1919)—showed considerable concern with the methodology of political economy in the first decade of the twentieth century and took a position decidedly against the prevailing orthodox Marxist view. This article presents Tugan’s approach to methodology and places it in historical context by briefly comparing it with other, more well known, views from the period such as those of John Neville Keynes and T. E. Cliffe Leslie. It also asks whether something that might be called a “Russian historical school”—or a Russian strand of “historical political economy”—existed prior to 1917, in parallel with the more famous German and Irish examples. While traditionally thought of as a “legal Marxist,” was Tugan also a key member of an “Eastern” historical school, and, if so, what were some of the main characteristics of his work in this respect?
