Abstract
The purpose of this paper is to demonstrate the evolution of international relations in Europe in the middle of the 5th century, which involved a struggle for hegemony between the Hunnish Empire ruled by Attila on the one hand and both of the Roman Empires - on the other hand. By the late spring of 452, Attila had gathered capable troops and went ahead with launching a new campaign into Italy, the heart of the Roman Empire. The Byzantine diplomacy managed to send Attila against the West and may have played its role in this. The Hun aristocracy and hordes are thought to spur their ruler into launching the campaign to capture new spoils of war too. At all events, it is necessary for us to objectively reconstruct the events of the Italian campaign
