Despite all that has been written about Russian historiography and how it profoundly changed after the Bolsheviks seized power in 1917, very little is known about the historical tradition immediately before the Soviet era. This article attempts to begin to address this issue by examining the major forces that shaped the historical and sociological thought of Nikolai Alesandrovich Rozhkov (1868–1927). It argues that as Kliuchevskii's successor and as the first professional historian to eventually present a Marxist analysis of Russian history, Rozhkov was not only the most important historian at that time but one whose work best represented the most significant transition in Russia's historical tradition. The article concludes that an examination of Rozhkov's historical methodology offers a new interpretation of the origins of Soviet historiography.
