Political development of medieval Europe.

Political development begins with the formation of the kingdoms of the barbarians, which were rather short-lived in their existence – in this regard, only the Frankish kingdom remained powerful. In the future, Europe acts as a conglomerate of large and small feudal states, which often wage wars among themselves. sometimes they manage to unite for common goals – either in alliances for war with each other or for conducting long military campaigns, for example, the Crusades, ostensibly for the purpose of protecting their Christian shrines in the East.
