From Rome the whole Western world had received its Christianity; she was the asylum of what learning had escaped the general desolation; and even in her ruins she preserved something of the majesty of her ancient greatness.  On these accounts she had a respect and a weight which increased every day amongst a simple religious people, who looked but a little way into the consequences of their actions.  The rudeness of the world was very favorable for the establishment of an empire of opinion.  The moderation with which the Popes at first exerted this empire made its growth unfelt until it could no longer be opposed; and the policy of later Popes, building on the piety of the first, continually increased it:  and they made use of every instrument but that of force.  They employed equally the virtues and the crimes of the great; they favored the lust of kings for absolute authority, and the desire of subjects for liberty; they provoked war, and mediated peace; and took advantage of every turn in the minds of men, whether of a public or private nature, to extend their influence, and push their power from ecclesiastical to civil, from subjection to independency, from independency to empire.

France had many advantages over the other parts of Europe.  The Saracens had no permanent success in that country.  The same hand which expelled those invaders deposed the last of a race of heavy and degenerate princes, more like Eastern monarchs than German leaders, and who had neither the force to repel the enemies of their kingdom nor to assert their own sovereignly.  This usurpation placed on the throne princes of another character, princes who were obliged to supply their want of title by the vigor of their administration.  The French monarch had need of some great and respected authority to throw a veil over his usurpation, and to sanctify his newly acquired power by those names and appearances which are necessary to make it respectable to the people.  On the other hand, the Pope, who hated the Grecian Empire, and equally feared the success of the Lombards, saw with joy this new star arise in the North, and gave it the sanction of his authority.  Presently after be called it to his assistance.  Pepin passed the Alps, relieved the Pope, and invested him with the dominion of a large country in the best part of Italy.

Charlemagne pursued the course which was marked out for him, and put an end to the Lombard kingdom, weakened by the policy of his father and the enmity of the Popes, who never willingly saw a strong power in Italy.  Then he received from the hand of the Pope the Imperial crown, sanctified by the authority of the Holy See, and with it the title of Emperor of the Romans, a name venerable from the fame of the old Empire, and which was supposed to carry great and unknown prerogatives; and thus the Empire rose again out of its ruins in the West, and, what is remarkable, by means of one of those nations which had helped to destroy it.
