First published in English in 1926, this work by Nikolai Bukharin, a highly influential Marxist and Soviet Politician who would later become one of the most famous victims of Stalin's show trials, expands upon Karl Marx's theory of historical materialism. Offering a Marxist interpretation of sociology, this reissue is important not only from a sociological and economic perspective, but is also extremely valuable as a socio-historical document of contemporary thought in the Soviet Union in the years following the Bolshevik revolution.
