This paper aims to construct a comprehensive theory of royal succession of Mencius. Basically, there are three distinct modes of royal succession described in the Mencius: abdication, hereditary succession, and revolution. Abdication involves the voluntary transfer of power by the incumbent ruler to a virtuous minister. Hereditary succession entails the transmission of power to the son of the incumbent ruler. Revolution marks the foundation of a new dynasty by deposing the incumbent ruler. What are their exact relationships? In contrast to (...) hereditary succession, which represents “rule by heredity,” abdication and revolution are often categorized together as “rule by virtue,” which became the backbone of the Confucian virtue politics. However, Mencius' writings, especially 5A5 and 5A6, suggest his clear intention to establish a coherent, or at least, compatible relationship between abdication and hereditary succession. This paper analyzes Mencius' discussions on royal succession to elucidate how he perceived the connection between abdication and hereditary succession, and to explore why he considered revolution as a separate category. In this study, I refer to the former as the “entrenched‐trust model” and distinguish the latter as “anticipated‐trust model.” The final section of the paper compares the three modes of royal succession in terms of the nature of the people's trust, the susceptibility of the people's approval, and the candidate's disinterest in power.
