This book is the English translation of the French original Les origins de la révolution chinoise, 1915-1949 first published in 1967. Notwithstanding the sixty five years that have since elapsed, I find it an extraordinarily enlightening introduction to the history of China in the first half of the twentieth century and in particular, as the title of the book let us to infer, to those factors (political, social, economic, military, and historical) that form the background of the Chinese revolution of 1949. The book opens with a brief overview chapter of the last half century of the Qing empire until the inauguration of the Republic in 1911, followed by another one on the intellectual climate and movements since the end of the empire, and then by a survey of the origins of the Communist Party, its foundation, the early alliance with the Kuomintang and the attempt at its extermination by the Kuomintang's government of Chiang Kai-Shek that led to the Great March. Then, in several chapters, we learn about the social situation (in particular in the countryside where the vast majority of Chinese people lived in terribly harsh conditions), the role of Nationalism, the chances (or lack thereof) for reform instead of revolution, the temporary alliance during the war against the Japanese invasion, and final the civil war and the chaotic final stages of the Nationalist regime. In barely two hundred pages we get an excellent and very lively and balanced account of the main facts and intervenors, as well as a discussion of the historic, intellectual, and ideological forces that shaped their action. A great book!
