Although the coronation has been regarded as so important as to have been called "the central event of the Middle Ages,"[169] it is by no means an easy task to determine precisely what significance it was thought to have at the time. We can look back upon it now and see that it marked the beginning of the so-called "Holy Roman Empire"--a creation that endured in _fact_ only a very short time but whose name and theory survived all the way down to Napoleon's reorganization of the German states in 1806. One view of the matter is that Charlemagne's coronation meant that a Frankish king had become the successor of Emperor Constantine VI., just deposed at Constantinople, and that therefore the universal Roman Empire was again to be ruled from a western capital as it had been before the time of the first Constantine. It will be observed that extract (a), taken from the Annals of Lauresheim, and therefore of German origin, at least suggests this explanation. But, whether or not precisely this idea was in the mind of those who took part in the ceremony, in actual fact no such transfer of universal sovereignty from Constantinople to the Frankish capital ever took place. The Eastern Empire lived right on under its own line of rulers and, so far as we know, aside from some rather vague negotiations for a marriage of Charlemagne and the Empress Irene, the new western Emperor seems never to have contemplated the extension of his authority over the East. His great aspiration had been to consolidate all the Germanic peoples of western continental Europe under the leadership of the Franks; that, by 800, he had practically done; he had no desire to go farther. His dominion was always limited strictly to the West, and at the most he can be regarded after 800 as not more than the reviver of the old western half of the Empire, and hence as the successor of Romulus Augustulus. But even this view is perhaps somewhat strained. The chroniclers of the time liked to set up fine theories of the sort, and later it came to be to the interest of papal and imperial rivals to make large use, in one way or another, of such theories. But we to-day may look upon the coronation as nothing more than a formal recognition of a condition of things already existing. By his numerous conquests Charlemagne had drawn under his control such a number of peoples and countries that his position had come to be that which we think of as an emperor's rather than that of simple king of the Franks. The Pope did not give Charlemagne his empire; the energetic king had built it for himself. At the most, what Leo did was simply to bestow a title already earned and to give with it presumably the blessing and favor of the Church, whose devoted servant Charlemagne repeatedly professed to be. That the idea of imperial unity still survived in the West is certain, and without doubt many men looked upon the ceremony of 800 as re-establishing such unity; but as events worked out it was not so
