Definition and stakes

Rome had ceased to be the imperial city. Did the loss of its bishop's prerogatives follow? Did they pass to Byzantium because it was become the imperial city, because the sole emperor dwelt there? Thus, about a hundred years after the repulse of the ambitious exaltation sought by Anatolius, its rejection by the provident wisdom and resolute courage of St. Leo was more than justified by the course of events. St. Leo's action was based upon the constitution of the Church, and therefore did not need to be justified by events.

The protection of the eastern emperor, Leo I., helped them in this resistance to Ricimer. The national party in Rome itself called on the Greek emperor for support. The utter dissolution of the western empire, when German tribes, Burgundians, Franks, Visigoths, and Vandals, had taken permanent possession of its provinces outside of Italy, while the violated dignity of Rome sank daily into greater impotence, now made Byzantium come forth as the true head of the empire.

So the division into East and West was cancelled: Italy as a province belonged still to the one emperor, who was seated at Byzantium. In theory, the unity of Constantine's time was restored; in fact, Rome and the West were surrendered to Teuton invaders. [16] This was the last stroke: the mighty members of the great mother—Gaul, and Spain, and Britain, and Africa, and Illyricum—had been severed from her. Now, the head, discrowned and impotent, submitted to the rule of Odoacer the Herule. The Byzantine supremacy remained in keeping for future use.
