鑁阿寺文書の再検討 : 古河公方研究のために

抄録

The chief aim of this article is to analyze the old letters (monjo) which are kept in the possession of Banna Temple (Bannaji) in Shimotsuke province and to further studies about the Kanto Ashikaga families. The contents of the Bannaji monjo are so complicated that very few students have ever made use of them. In this paper, therefore, the author was obliged to take as his chief subject the general framework and meaning of the letters. Furthermore, in this research the materials were carefully selected and limited to the later Middle Ages. But, even then the sources are of quite a considerable number. In the past it has been thought that these letters had been filed into two groups : undated letters (a sort of hosho) dating mainly from the Sengoku period and those letters connected with the Koga-Kubo Ashikaga families. But, after careful examination, it became apparent that the latter consisted of two different groups of letters, the Kogasama monjo and the Shakesama monjo. Most of the Kogasama monjo date from the later Muromachi and Sengoku periods (mid-15th to 16th cent.). The author tried to prove this by checking and investigating each of the successive generations of the Kogasama and Shakesama families and their attendants. Thus, the so-called Bannaji monjo in the latter period of the Middle Ages were made up of two massive groups of letters related to the Kogasama and Shakesama families. And, in addition, they had a three group connection -Bannaji-Shakesama-Kogasama -as was publicly manifest by the right of recommendation belonging to the Shakesama family and the right of appointment belonging to the Kogasama family. In the start of the 16th century these relations came to an end with the decline of the Shakesama family's power. Thus, there emerged a direct link between Bannaji and the Kogasama family. But, in the latter half of the 16th century, in the era of Yoshiuji Ashikaga, a new three group connection was set up among Bannaji, Hoshuin, and Kurihashisama.
