Aretrospective assessment at mid-century might have suggested that the course of Chinese history between 1900 and 1950 recorded only two events of enduring political significance: the first, the fall of the Ch'ing dynasty in October 1911 and, with it, destruction of the imperial system which had lasted for two millennia; the second, the establishment of the People's Republic of China in October 1949 and, through it, commitment to accelerated modernization and forced industrialization along lines similar to those plotted earlier by the Soviet Union. Simultaneously, assessment of the future might well have concluded, with prescience born of objectivity, that the effect of the Chinese Communist explosion on both Chinese and world politics would merit a major effort on the part of American social science research.
