The combination of Confucianism and feudal autocracy in creating a unified China has always been a controversial subject. It is thus essential to find a way to understand the inner values and outer practices in the theory of “Outer Kingliness” (wai wang) in the “Spring and Autumn Annals”. The explanation for this theory has always been obscure, so its origin has been considered from many sources. This article contends that the “Unify China” theory found expression from the “Spring and Autumn Annals” notions of “respect for the monarch” (zun wang), and “revolution” (ge ming shuo). The “Unify China” theory was historically opposed to feudal aristocracy and the notion of “employing power, not morality” (ren lier bu ren de). These two theories have always held each other in check in the course of Chinese history. They have kept China from disintegrating as the Roman empire had. This article attempts to explain this political phenomenon and its special characteristics.
