In the year 751 [[7]] Pope Zechary deposed Childeric, a slothful and useless King of France, and the last of the race of Merovæus; and absolving his subjects from their oath of allegiance, gave the kingdom to Pipin the major of the Palace; and thereby made a new and potent friend. His successor [[8]] Pope Stephen III, knowing better how to deal with the Greek Emperor than with the Lombards, went the next year to the King of the Lombards, to persuade him to return the Exarchate to the Emperor. But this not succeeding, he went into France, and persuaded Pipin to take the Exarchate and Pentapolis from the Lombards, and give it to St. Peter. Accordingly Pipin A.C. 754 came with an army into Italy, and made Aistulphus King of the Lombards promise the surrender: but the next year Aistulphus, on the contrary, to revenge himself on the Pope, besieged the city of Rome. Whereupon the Pope sent letters to Pipin, wherein he told him that if he came not speedily against the Lombards, pro data sibi potentia, alienandum fore à regno Dei & vita æterna, he should be excommunicated. Pipin therefore, fearing a revolt of his subjects, and being indebted to the Church of Rome, came speedily with an army into Italy, raised the siege, besieged the Lombards in Pavia, and forced them to surrender the Exarchate and region of Pentapolis to the Pope for a perpetual possession. Thus the Pope became Lord of Ravenna, and the Exarchate, some few cities excepted; and the keys were sent to Rome, and laid upon the confession of St. Peter, that is, upon his tomb at the high Altar, in signum veri perpetuique dominii, sed pietate Regis gratuita, as the inscription of a coin of Pipin hath it. This was in the year of Christ 755. And henceforward the Popes being temporal Princes, left off in their Epistles and Bulls to note the years of the Greek Emperors, as they had hitherto done.
After this [[9]] the Lombards invading the Pope's countries, Pope Adrian sent to Charles the great, the son and successor of Pipin, to come to his assistance. Accordingly Charles entered Italy with an army, invaded the Lombards, overthrew their kingdom, became master of their countries, and restored to the Pope, not only what they had taken from him, but also the rest of the Exarchate which they had promised Pipin to surrender to him, but had hitherto detained; and also gave him some cities of the Lombards, and was in return himself made Patricius by the Romans, and had the authority of confirming the elections of the Popes conferred upon him. These things were done in the years 773 and 774. This kingdom of the Lombards was the second kingdom which fell before the little horn. But Rome, which was to be the seat of his kingdom, was not yet his own.
In the year 796, [[10]] Leo III being made Pope, notified his election to Charles the great by his Legates, sending to him for a present, the golden keys of the Confession of Peter, and the Banner of the city of Rome: the first as an acknowledgment of the Pope's holding the cities of the Exarchate and Lombardy by the grant of Charles; the other as a signification that Charles should come and subdue the Senate and people of Rome, as he had done the Exarchate and the kingdom of the Lombards. For the Pope at the same time desired Charles to send some of his Princes to Rome, who might subject the Roman people to him, and bind them by oath in fide & subjectione, in fealty and subjection, as his words are recited by Sigonius. An anonymous Poet, publish'd by Boeclerus at Strasburg, expresseth it thus:
Admonuitque piis precibus, qui mittere vellet
Ex propriis aliquos primoribus, ac sibi plebem
Subdere Romanam, servandaque fœdera cogens
Hanc fidei sacramentis promittere magnis.
Hence arose a misunderstanding between the Pope and the city: and the Romans about two or three years after, by assistance of some of the Clergy, raised such tumults against him, as gave occasion to a new state of things in all the West. For two of the Clergy accused him of crimes, and the Romans with an armed force, seized him, stript him of his sacerdotal habit, and imprisoned him in a monastery. But by assistance of his friends he made his escape, and fled into Germany to Charles the great, to whom he complained of the Romans for acting against him out of a design to throw off all authority of the Church, and to recover their antient freedom. In his absence his accusers with their forces ravaged the possessions of the Church, and sent the accusations to Charles; who before the end of the year sent the Pope back to Rome with a large retinue. The Nobles and Bishops of France who accompanied him, examined the chief of his accusers at Rome, and sent them into France in custody. This was in the year 799. The next year Charles himself went to Rome, and upon a day appointed presided in a Council of Italian and French Bishops to hear both parties. But when the Pope's adversaries expected to be heard, the Council declared [[11]] that he who was the supreme judge of all men, was above being judged by any other than himself: whereupon he made a solemn declaration of his innocence before all the people, and by doing so was looked upon as acquitted.
Soon after, upon Christmas-day, the people of Rome, who had hitherto elected their Bishop, and reckoned that they and their Senate inherited the rights of the antient Senate and people of Rome, voted Charles their Emperor, and subjected themselves to him in such manner as the old Roman Empire and their Senate were subjected to the old Roman Emperors. The Pope crowned him, and anointed him with holy oil, and worshipped him on his knees after the manner of adoring the old Roman Emperors; as the aforesaid Poet thus relates:
Post laudes igitur dictas & summus eundem
