Outline of Final Research Achievements

This study aims to provide a multifaceted analysis of the diplomatic policies between the 13th-century Byzantine exiled emperor, John III (1221-1254), and various powers, which have previously been analyzed within the framework of bilateral relations. By examining the intentions and historical significance of individual diplomatic policies within the broader context of John III's diplomatic strategy, this research seeks to shed light on the complexities of his foreign relations.

Through diplomatic negotiations with figures such as Frederick II of the Hohenstaufen dynasty, the Papal See, Epirus, and the Seljuks, it becomes evident that behind each of these interactions, particularly influenced by the expansion of the Mongol Empire on a Eurasian scale, there were broader political transformations affecting individual negotiations.

Academic Significance and Societal Importance of the Research Achievements

本研究は亡命期のビザンツ政権を一つの軸として、それが他の勢力と織りなした関係の有り様を多角的に分析することを目指したものである。本研究が対象とした13世紀の前半は、その後現代にまで至るユーラシア西部の政治的変容の決定的時期であり、この時期における政治的諸関係の解明は、現代の同地域における様々な問題とメリットを考える上で重要な基盤的意義を持つ。
