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. If we take in the conquests of Charlemagne, it was also very near as extensive as formerly; though its constitution was altogether different, as being entirely on the Northern model of government. From Charlemagne the Pope received in return an enlargement and a confirmation of his new territory. Thus the Papal and Imperial powers mutually gave birth, to each other. They continued for some ages, and in some measure still continue, closely connected, with a variety of pretensions upon each other, and on the rest of Europe. Though, the Imperial power had its origin in France, it was soon divided into two branches, the Gallic and the German. The latter alone supported the title of Empire; but the power being weakened by this division, the Papal pretensions had the greater weight. The Pope, because he first revived the Imperial dignity, claimed a right of disposing of it, or at least of giving validity to the election of the Emperor. The Emperor, on the other hand, remembering the rights of those sovereigns whose title he bore, and how lately the power which insulted him with such demands had arisen from the bounty of his predecessors, claimed the same privileges in the election of a Pope. The claims of both were somewhat plausible; and they were supported, the one by force of arms, and the other by ecclesiastical influence, powers which in those days were very nearly balanced. Italy was the theatre upon which this prize was disputed. In every city the parties in favor of each of the opponents were not far from an equality in their numbers and strength. Whilst these parties disagreed in the choice of a master, by contending for a choice in their subjection they grew imperceptibly into freedom, and passed through the medium of faction and anarchy into regular commonwealths. Thus arose the republics of Venice, of Genoa, of Florence, Sienna, and Pisa, and several others. These cities, established in this freedom, turned the frugal and ingenious spirit contracted in such communities to navigation and traffic; and pursuing them with skill and vigor, whilst commerce was neglected and despised by the rustic gentry of the martial governments, they grew to a considerable degree of wealth, power, and civility.
