The theory of imperialism is primarily associated with the most prominent figures in the history of European Marxism. However, the theory was actually developed through engaged debates within the Second International from 1898-1916. This volume assembles and translates for the first time all of the main documents produced over the course of these discussions. It is part of the Historical Materialism Book Series.

Responses to Marx's Capital: From Rudolf Hilferding to Isaak Illich Rubin is a collection of primary sources dealing with the reception of the economic works of Karl Marx from the First to the Third International. The documents, translated for the first time from German and Russian, range from the original reviews of the three volumes of Capital and the three volumes of Theories of Surplus Value to the debates between the Marxist economists and the bourgeois academic representatives of the theory of marginal utility and the German historical school.

The theory of Permanent Revolution has been associated with Leon Trotsky for more than a century since the first Russian Revolution in 1905. Trotsky was the most brilliant proponent of Permanent Revolution but by no means its sole author. The documents in this volume, most of them translated into English for the first time, demonstrate that Trotsky was one of several participants in a debate from 1903-7 that involved numerous leading international Marxists, including Karl Kautsky, Rosa Luxemburg, Franz Mehring, Parvus and David Ryazanov.
