The role of "Reichsitalien"(feudal system of the Holy Roman Empire in Italia) in the early modern European international relationship

17世纪的意大利被认为是主权国家制度的早期典范。基于这一观点，在这个项目中，研究了神圣罗马皇帝和意大利公国之间的关系，这些公国以前是他的领地(所谓的德国“德意志帝国”或意大利“Feudi Imperiali”)，特别是在人口学方面。因此，人们发现，这一制度充分发挥了作用，可以通过皇帝和西班牙国王的附庸王子网络维持他们之间的和平。因此，这个“帝国”有效地发挥了政治制度的作用，不是主权国家的政治制度，而是皇帝司法权利和米兰公爵(西班牙国王)行政权力下的某些人的网络的政治制度，尽管自17世纪末以来，这些公国一直由皇帝在其军事占领上直接管理。这意味着它们不是主权国家国际体系的早期模式。

Italy of 17. century has been believed to be a early model of the system of the sovereign states. To this view, in this project the relationship between the Holy Roman Emperors and the Italian principalities which were formally the fiefs of him (so-called German "Reichsitalien" or Italian "feudi imperiali") was reserched, especially focused on the prosopography. Consequently it was found that this system was worked enough to keep the peace among them by the networks of the client-princes of Emperors and Spanish Kings. Thus this "Reichsitalien" functioned effrectively as a political system not of the sovereign states but of the certain human networks under the juridical right of the Emperors and the executive power of the Dukes Milan (Spanish Kings), although this principalities have been directly governed by the Emperors on their military occupations since the end of the 17. century. It means that they were not the early model of the international system of the sovereign states.
