The appearance of Charlemagne, the resurrection of the empire in the West, confirm and consolidate the misfortune of 751 in which indeed she lost everything. But when we see the great Frank strip the imperial palace of its marbles and mosaics it is as though the fate of Ravenna had been expressed in some great ceremony and not by unworthy hands. An emperor had set her up so high, an emperor had kept her there so long; it was an emperor who, as in a last great rite, stript her of her apparel and left her naked with her memories.

Those memories, not only splendid and glorious, but gaunt and terrible too, smoulder in her ruined heart as the fire may do in the ashes when all that was living and glorious has been consumed. Almost nothing as she became when Charlemagne left her, a mere body still wrapt in gorgeous raiment stiff with gold, but without a soul, she still dreamt of dominion, of empire, and of power. Governed by her archbishops, she rebelled against Rome, struggled for a secular and sometimes a religious autonomy, and came at last, as surely might have been prophesied, to consider herself as a feudatory of the Empire, not of the Church.
But though this struggle might have been foreseen it is futile, it has no life in it, it is without any real importance, it leads nowhere and fails to interest us. All that really concerns us in the confused story of Ravenna from the time of the resurrection of the empire till our own day are two strange incidents that have nothing fundamentally to do with her, that befell her by chance; I mean the apparition of Dante, when we see the most eager mediaeval apologist of the imperial idea fortunately and rightly find in her a refuge and a tomb; and the battle of 1512 in which fell Gaston de Foix and which cost the lives of twelve thousand men and achieved nothing.
Nevertheless Ravenna, for so long the citadel of the empire in the West, of all the cities of Italy was least likely to forget her origin or to forsake her memories, and it is both curious and interesting to watch her entry, little splendid though that entry be, into the marvellously vital world of the Middle Age in Italy.
The slow re-establishment of Latin power which followed the crowning of Charlemagne, and which the Church secured by that act, first began to come to its own with the rise of the bishops to civil power in the cities of Italy. Now Ravenna had certainly been governed by her archbishop ever since Pepin in 754 had forced Aistulf to place the keys of the city upon the tomb of the Prince of the Apostles. If nowhere else in the Cisalpine plain, Latin civilisation and law, then, never failed in Ravenna, and whatever may have happened elsewhere it might seem certain that here in Ravenna and probably throughout the exarchate the curia existed and endured throughout the barbarian confusion.
This would explain the early and extraordinary development of communal institutions in Ravenna. And since, one may believe, the Roman legions were replaced throughout the empire by the religious orders, it is interesting to know that in the tenth century her Latin energy is borne witness to by the fact that in 956 she produced S. Romuald of the Onesti family of Ravenna, who was educated in the Benedictine monastery of Classe and who founded the Order of Camaldoli, and toward the end of the same century, in 988, she produced S. Peter Damian, the brother of the arch-priest of Ravenna, cardinal-bishop of Ostia and papal legate in Milan.
Nor with the rise of the "spirito italico" everywhere in Italy do we find Ravenna exhausted. Far from it, she is as ardent as any other city of the peninsula whatsoever. Only always she is anti-papal, as though, living in her memories, as she could not but do, and this was her greatest strength, she remembered her old allegiance to the emperor and could not forget that when the pope became his heir in Italy she had fallen from her old eminence. Thus as early as the first years of the eleventh century her archbishop obtains confirmation from the emperor of his temporal powers, in which confirmation no recognition of the sovereignty of the pope appears at all. This act of allegiance to the emperor was repeated when Barbarossa appeared, and indeed the archbishops of Ravenna soon became the most eager if not most the serious supporters of the emperors in all the great plain and perhaps in all Italy. Ravenna, once the imperial capital, though fallen was imperial still. She was haunted, haunted by ghosts that were restless in those marvellous tombs, that litter her churches, loom out of the grey curtain of mist like a fortress, or shine and glitter with imperishable colours and are full of memories as imperishable as themselves.
Yet though it was to her the emperors so often looked for aid and succour and rest, it was not always so. The present, even with her, was more than the past. With the great development of communal institutions which marked especially the twelfth century, compelled too to face, though never with success, the increasing state of Venice, which, indeed, and successfully, had usurped her place in the world and had realised what she had failed to achieve, she was ready and able in 1198 to place herself at the head of the league of the cities of the Romagna and the Marches against the imperial power then both oppressive and feeble; so that pope Innocent III. found it easy to restore the unforgotten rights of the Holy See there and these were ratified by Otto IV. and by Frederick II. as the price of papal support.
It will thus be readily understood that if, at the opening of the thirteenth century, there was one city in Italy more certain than another to be at the mercy of the universal quarrel of Guelf and Ghibelline, that city was Ravenna. In its larger sense that quarrel was her inheritance. It was the one thought which filled her mind. But here, as elsewhere, the great quarrel was insoluble or at any rate not to be solved. It merely bred faction and divided the city against itself. Guelf and Ghibelline tore Ravenna as they tore Florence and Siena in pieces.
