Legal Marxism was a Russian Marxist movement based on a particular interpretation of Marxist theory whose proponents were active in socialist circles between 1894 and 1901. The movement's primary theoreticians were Pyotr Struve, Nikolai Berdyaev, Sergei Bulgakov, Mikhail Tugan-Baranovsky and Semyon Frank. The name was derived from the fact that its supporters promoted their ideas in legal publications.
Unlike the earlier generation of Russian socialists known as narodniks (populists), who emphasized the role of the peasantry in transitioning to socialism, Legal Marxists used the economic theory of Karl Marx to argue that the development of capitalism in the Russian Empire was both inevitable and beneficial. As Struve put it, they provided a "justification for capitalism" in Russia.
Legal Marxists held numerous open debates from the mid-1890s through the early 1900s, notably at the Free Economic Society in Saint Petersburg, and published three magazines between 1897 and 1901, all of them eventually suppressed by the imperial government:
Legal Marxists became particularly influential after the arrest and imprisonment of the leaders of the revolutionary wing of Russian Marxism (including Julius Martov and Vladimir Lenin) in 1895-1896. Legal Marxists and revolutionary Marxists were allied in the late 1890s within the newly formed Russian Social Democratic Labor Party, whose Manifesto Struve wrote in 1898 and Legal Marxists magazines were extensively used by revolutionary Marxists living in exile or abroad to publish their writings.
