曹魏爵制に關する二三の考察

Abstract

With a view to clarifying a few interesting points on the peerage system of the Wei of the Three Dynasties period, firstly the author takes up the process of formation of the Ts'ao-Wei peerage, where it consisted of the five-grade peerage of the Chou period, the lieh-hou 列侯 and khuan-nei-hou 關内侯 titles after the Ch'in-Han system, and the peerage created by Wei itself. Secondly, the author discusses the size of the lieh-hou and khuan-nei-hou fiefs in terms of household and their inner structure. Lastly, the author points out that heir apparency was widened under the Wei, though the "inheritance by real son" principle of the Han period was still in practice. In view of the fact that fiefs were sometimes divided even in the life-time of lord the author relates the Wei peerage to its noble lineage system.
