Comparative Outline of the Terms “Great Unification”, “China”, and “All-under-Heaven”


The concepts “Great Unification” (Dayitong 大一統), “China” (Zhongguo 中國), and “all-under-Heaven” (Tianxia 天下) are all research topics which continue to attract the focus of the Chinese historical community. The three concepts are both related and different. This paper conducts a preliminary comparative analysis of the content of the three concepts and the role that they play in specific historical studies. It finds that the concept “China” emphasizes the origin of Huaxia 華夏 civilization and its significance as a center for expansion and Sinicization of surrounding ethnic groups. The concept “all-under-Heaven,” meanwhile, places more stress on the overall political governance relationship between the center and the periphery. Finally, the concept “Great Unification” focuses on the process by which a dynasty establishes its legitimacy in terms of both ideology and practice. Only by examining the three concepts together can we fully grasp the overall direction and characteristics of Chinese history.
