Book excerpt: U.S. Trotskyism 1928-1965. Part III: Resurgence: Uneven and Combined Development is the third of a documentary trilogy on a revolutionary socialist split-off from the U.S. Communist Party, reflecting Leon Trotsky’s confrontation with Stalinism in the global Communist movement. Spanning 1954 to 1965, this volume surveys the Cold War era, the civil rights and black liberation movements, the 'third wave' of feminism, and other social and cultural developments of the 1950s and 1960s. Documenting responses to a variety of anti-colonial and revolutionary insurgencies, the volume also surveys the crisis and decline of Stalinism. Attention is given to internal debates and splits, but also to the partial reunification of the international Trotskyist movement (the Fourth International), as well as substantial contributions to the study of history and the development of Marxist theory. Scholars and activists will find much of interest in these primary sources.
