A crown jewel of New Left historiography, this overview of U.S. Marxism was hailed on its first publication for its nuanced storytelling, balance and incredible sweep. Brimming over with archival finds and buoyed by the recollections of witnesses and participants in the radical movements of decades past, Marxism in the United States includes fascinating accounts of the immigrant socialism of the nineteenth century, the formation of the CPUSA in the wake of the Bolshevik Revolution, the rise of American communism and of the hugely influential Popular Front in the 1920s and '30s, the crisis and split of the '50s, and the revival of Marxism in the '60s and '70s. This revised and updated edition also takes into account the last quartercentury of life in the U.S., bringing the story of American Marxism up to the present. With today's resurgent interest in radicalism, this new edition provides an unparalleled guide to 150 years of American left history.
