Research about the problems caused by contacts and integrations of different nations in European history

关于不同民族或文化的接触在当代世界所带来的问题，我们首先从以前收集的书籍中挑选和整理了许多不同民族的接触、对立、合作、同化和融合的案例。同时，我们通过历史资料分析了古希腊（Maeno）的殖民案例和现代德国（Nagata）的犹太人同化案例，并将结果作为历史期刊的专著呈现。然后，我们也比较了彼此的结果，试图找出这两个案例的相似之处和当代世界的接触问题。例如，我们已经证实，古希腊的“部落”和现代德国的“民族国家”在某种程度上源于“想象的共同体”，并通过有意识或无意识地逐渐形成共同的传统、传说、神话或共同的敌人，明确了其统一性。在未来，我们也希望通过进一步收集和比较欧洲历史上的其他一体化模式来加深我们的知识。

About the problems which contacts of different nations or cultures bring about in the contemporary world, we have picked up and arranged at first many cases of contacts, oppsitions, cooperations, assimilations, and fusions of different nations through books we have collected before.Simultaneously we have analyzed cases of colonization in Ancient Greece (by Maeno) and assimilation of Jews in Modern Germany (by Nagata) through historical materials and presented the results as monographs of historical periodicals. And then, we have also compared the results of each other and tried to find out the similarity of those two cases and contact-problems of contemporary world.For example, we have confirmed that the "tribe" of Ancienct Greece as well as the "nation state" of Modern Germany derived somewhat from "imagened communities" and made its unity clearly through gradual formation of its common traditions, legends, myths or its common enemies, consciously or unconsciously.We want, in future also, to deepen our knowledges from further collecting and comparing of other models of integration in the history of Europe.
