A second, if not equally strong bond for the empire, was the Frankish nationality and the political institutions based upon it. With their swords the victorious Franks had gained control of the West, had made themselves rulers of the Germanic and Latin world; the empire, though it called itself Roman, was nevertheless only an extension of the kingdom of the Franks.
