The Historians' History of the World 07 [The History of the Later Roman Empire]

The opposition Leo encountered only confirmed him in his persuasion that it was indispensably necessary to increase the power of the central government in the provinces. As he was sincerely attached to the opinions of the iconoclasts, he was led to connect his ecclesiastical reforms with his political measures, and to pursue both with additional zeal. In order to secure the active support of all the officers of the administration, and exclude all image-worshippers from power, he convoked an assembly, called a silentium, consisting of the senators and the highest functionaries in the church and state. In this solemn manner it was decreed that images were to be removed from all the churches throughout the empire.

[729-751 A.D.]

Gregory II sent Leo strong representations against his first edicts on the subject of image-worship, and after the silentium he repeated these representations, and entered on a more decided course of opposition to the emperor’s ecclesiastical reforms, being then convinced that there was no hope of Leo abandoning his heretical opinions. It seems that Italy, like the rest of the empire, had escaped in some degree from the oppressive burden of imperial taxation during the anarchy that preceded Leo’s election. But the defeat of the Saracens before Constantinople had been followed by the re-establishment of the fiscal system. To overcome the opposition now made to the financial and ecclesiastical reforms, the exarch Paul was ordered to march to Rome and support Marinus, the duke, who found himself unable to contend against the papal influence.

The whole of central Italy burst into rebellion at this demonstration against its civil and religious interests. The exarch was compelled to shut himself up in Ravenna; for the cities of Italy, instead of obeying the imperial officers, elected magistrates of their own, on whom they conferred, in some cases, the title of duke. Assemblies were held, and the project of electing an emperor of the West was adopted; but the unfortunate result of the rebellion of Greece damped the courage of the Italians; and though a rebel, named Tiberius Petasius, really assumed the purple in Tuscany, he was easily defeated and slain by Eutychius, who succeeded Paul as exarch of Ravenna. Liutprand, king of the Lombards, taking advantage of these dissensions, invaded the imperial territory, and gained possession of Ravenna; but Gregory, who saw the necessity of saving the country from the Lombards and from anarchy, wrote to Ursus the duke of Venice, one of his warm partisans, and persuaded him to join Eutychius. The Lombards were defeated by the Byzantine troops, Ravenna was recovered, and Eutychius entered Rome with a victorious army. Gregory died in 731. Though he excited the Italian cities to resist the imperial power, and approved of the measures they adopted for stopping the remittance of their taxes to Constantinople, he does not appear to have adopted any measures for declaring Rome independent.

From 733 A.D., the city of Rome enjoyed political independence under the guidance and protection of the popes; but the officers of the Byzantine emperors were allowed to reside in the city, justice was publicly administered by Byzantine judges, and the supremacy of the Eastern Empire was still recognised. So completely, however, had Gregory III thrown off his allegiance, that he entered into negotiations with Charles Martel, in order to induce that powerful prince to take an active part in the affairs of Italy. The pope was now a much more powerful personage than the exarch of Ravenna, for the cities of central Italy, which had assumed the control of their local government, entrusted the conduct of their external political relations to the care of Gregory, who thus held the balance of power between the Eastern emperor and the Lombard king. In the year 742, while Constantine V, the son of Leo, was engaged with a civil war, the Lombards were on the eve of conquering Ravenna, but Pope Zacharias threw the whole of the Latin influence into the Byzantine scale, and enabled the exarch to maintain his position until the year 751, when Aistulf, king of the Lombards, captured Ravenna. The exarch retired to Naples, and the authority of the Byzantine emperors in central Italy ended.n
