The republication of Karl Korsch's Karl Marx (1938) makes available to a new generation of readers the most concise account of Karl Marx's thought by one of the major figures of twentieth-century Western Marxism.

Karl Korsch (1886-1961) was one of the most significant Marxist writers of the twentieth century. Along with Georg Lukacs's History and Class Consciousness, Korsch's Marxism and Philosophy (1923) stands as one of the two major contributions to the study of the philosophical underpinnings of Marxist theory.
