World Communism: A History of The Communist International by F. Borkenau with a New Introduction by Raymond Aron covers topics such as the Russian Revolutionary Movement, Bolshevism, labor in the war, the German revolution, the foundation and various phases of the Communist International, China's revolution and soviets, and significant historical events up to the rise of Hitler and the role of the Comintern in colonial contexts. In the new introduction, Aron emphasizes the historical context of Borkenau's original work, written in 1939. He discusses the significance of the book's conclusions, its enduring relevance, and Borkenau's sound analysis of Bolshevik ideology and its incompatibility with Western proletarian movements. Aron reflects on the phases of the Comintern’s influence and its broader implications on revolutions in Europe and Asia, particularly noting the distinct revolutionary circumstances in China. The book includes significant chapter coverage of key historical moments and analyses the systematic echoes between Bolshevik principles and their global impact. It is an essential read for those studying the intricate developments and historical contexts of international Communism and Marxism.
