Outline of Final Research Achievements

This study, targeting on Daimyos (feudal clans) on the coast of the Sea of Japan, elucidated actual conditions and significances of information collection and exchange between a Daimyo and another or between a Daimyo and the shogunate; for example, about the information acquisition of Daimyos in the northeast region before and after Sekigahara battle, the information network in the formation process of Kaga clan vassal group and the role of personal connection in the negociations between Hagi clan and the shogunate. In addition, the political trend of Fukui clan, Tsuyama clan, Akita clan and the shogunate in Matsudaira Tadanao incident, a political milestone in the early 17th century, was elucidated through both the fact investigation using the primary historical materials and the transition of discourse seen in genealogies of Daimyos and their vassals. These research results were published as a research report, "Early Modern Daimyos and information".
