A Saxon Emperor was, before his coronation at Rome, 'rex,' or 'rex Francorum Orientalium,' or 'Francorum atque Saxonum rex;' after it, simply 'Imperator Augustus.' Otto III is usually said to have introduced the form 'Romanorum Imperator Augustus,' but some authorities state that it occurs in documents of the time of Lewis I.
Henry II and his successors, not daring to take the title of Emperor till crowned at Rome (in conformity with the superstitious notion which had begun with Charles the Bald), but anxious to claim the sovereignty of Rome, as indissolubly attached to the German crown, began to call themselves 'reges Romanorum.' The title did not, however, become common or regular till the time of Henry IV, in whose proclamations it occurs constantly.
From the eleventh century till the sixteenth, the invariable practice was for the monarch to be called 'Romanorum rex semper Augustus,' till his coronation at Rome by the Pope; after it, 'Romanorum Imperator semper Augustus.'
In A.D. 1508, Maximilian I, being refused a passage to Rome by the Venetians, obtained a bull from Pope Julius II permitting him to call himself 'Imperator electus' (erwählter Kaiser). This title Ferdinand I (brother of Charles V) and all succeeding Emperors took immediately upon their German coronation, and it was till A.D. 1806 their strict legal designation[429], and was always employed by them in proclamations or other official documents. The term 'elect' was however omitted, even in formal documents when the sovereign was addressed or spoken of in the third person; and in ordinary practice he was simply 'Roman Emperor.'
Maximilian added the title 'Germaniæ rex,' which had never been known before, although the phrase 'rex Germanorum' may be found employed once or twice in early times. 'Rex Teutonicorum,' 'regnum Teutonicum[430] ,' occur often in the tenth and eleventh centuries. A great many titles of less consequence were added from time to time. Charles the Fifth had seventy-five, not, of course, as Emperor, but in virtue of his vast hereditary possessions[431].
It is perhaps worth remarking that the word Emperor has not at all the same meaning now that it had even so lately as two centuries ago. It is now a commonplace, not to say vulgar, title, somewhat more pompous than that of King, and supposed to belong especially to despots. It is given to all sorts of barbarous princes, like those of China and Abyssinia, in default of a better name. It is peculiarly affected by new dynasties; and has indeed grown so fashionable, that what with Emperors of Brazil, of Hayti, and of Mexico, the good old title of King seems in a fair way to become obsolete[432]. But in former times there was, and could be but one Emperor; he was always mentioned with a certain reverence: his name summoned up a host of thoughts and associations, which we cannot comprehend or sympathize with. His office, unlike that of modern Emperors, was by its very nature elective, and not hereditary; and, so far from resting on conquest or the will of the people, rested on and represented pure legality. War could give him nothing which law had not given him already: the people could delegate no power to him who was their lord and the viceroy of God.
II. The Crowns.
Of the four crowns something has been said in the text. They were those of Germany, taken at Aachen; of Burgundy, at Arles; of Italy, sometimes at Pavia, more usually at Milan or Monza; of the world, at Rome.
The German crown was taken by every Emperor after the time of Otto the Great; that of Italy by every one, or almost every one, who took the Roman down to Frederick III, by none after him; that of Burgundy, it would appear, by four Emperors only, Conrad II, Henry III, Frederick I, and Charles IV. The imperial crown was received at Rome by most Emperors till Frederick III; after him by none save Charles V, who obtained both it and the Italian at Bologna in a somewhat informal manner. But down to A.D. 1806, every Emperor bound himself by his capitulation to proceed to Rome to receive it.
It should be remembered that none of these inferior crowns was necessarily connected with that of the Roman Empire, which might have been held by a simple knight without a foot of land in the world. For as there had been Emperors (Lothar I, Lewis II, Lewis of Provence (son of Boso), Guy, Lambert, and Berengar) who were not kings of Germany, so there were several (all those who preceded Conrad II) who were not kings of Burgundy, and others (Arnulf, for example) who were not kings of Italy. And it is also worth remarking, that although no crown save the German was assumed by the successors of Charles V, their wider rights remained in full force, and were never subsequently relinquished. There was nothing, except the practical difficulty and absurdity of such a project, to prevent Francis II from having himself crowned at Arles[433], Milan, and Rome.
