In the ninth year of his reign Charlemagne gathered his warriors for a crusade against the Saracens in Spain. He crossed the Pyrenees, and succeeded in wresting from the Moslems all the northeastern corner of the peninsula. As he was leading his victorious bands back across the Pyrenees, the rear of his army under the lead of the renowned paladin Roland, while hemmed in by the walls of the Pass of Roncesvalles, was set upon by the wild mountaineers (the Gascons and Basques), and cut to pieces before Charlemagne could give relief. Of the details of this event no authentic account has been preserved; but long afterwards it formed the favorite theme of the tales and songs of the Troubadours of Southern France.

But by far the greater number of the campaigns of Charlemagne were directed against the pagan Saxons, who almost alone of the German tribes still retained their ancient idolatry. Thirty years and more of his reign were occupied in these wars across the Rhine. Reduced to submission again and again, as often did the Saxons rise in desperate revolt. The heroic Witikind was the "second Arminius" (see p. 308) who encouraged his countrymen to resist to the last the intruders upon their soil. Finally, Charlemagne, angered beyond measure by the obstinacy of the barbarians, caused 4500 prisoners in his hands to be massacred in revenge for the contumacy of the nation. The Saxons at length yielded, and accepted Charlemagne as their sovereign, and Christianity as their religion.

RESTORATION OF THE EMPIRE IN THE WEST (800).—An event of seemingly little real moment, yet, in its influence upon succeeding affairs, of the very greatest importance, now claims our attention. Pope Leo III. having called upon Charlemagne for aid against a hostile faction at Rome, the king soon appeared in person at the capital, and punished summarily the disturbers of the peace of the Church. The gratitude of Leo led him at this time to make a most signal return for the many services of the Frankish king. To understand his act a word of explanation is needed.

For a considerable time a variety of circumstances had been fostering a growing feeling of enmity between the Italians and the emperors at Constantinople. Disputes had arisen between the churches of the East and those of the West, and the Byzantine rulers had endeavored to compel the Italian churches to introduce certain changes and reforms in their worship, which had aroused the most determined opposition of the Roman bishops, who denounced the Eastern emperors as schismatics and heretics. Furthermore, while persecuting the orthodox churches of the West, these unworthy emperors had allowed the Christian lands of the East to fall a prey to the Arabian infidels.

Just at this time, moreover, by the crime of the Empress Irene, who had deposed her son Constantine VI., and put out his eyes, that she might have his place, the Byzantine throne was vacant, in the estimation of the Italians, who contended that the crown of the Cæsars could not be worn by a woman. Confessedly it was time that the Pope should exercise the power reposing in him as Head of the Church, and take away from the heretical and effeminate Greeks the Imperial crown, and bestow it upon some strong, orthodox, and worthy prince in the West.

Now, among all the Teutonic chiefs of Western Christendom, there was none who could dispute the claims to the honor with the king of the Franks, the representative of a most illustrious house, and the strongest champion of the young Christianity of the West against her pagan foes. Accordingly, as Charlemagne was participating in the festivities of Christmas Day in the Cathedral of St. Peter at Rome, the Pope approached the kneeling king,— who declared afterwards that he was wholly ignorant of the designs of his friend,—and placing a crown of gold upon his head, proclaimed him emperor of the Romans, and the rightful and consecrated successor of Cæsar Augustus and Constantine (800).

The intention of Pope Leo was, by a sort of reversal of the act of Constantine, to bring back from the East the seat of the Imperial court; but what he really accomplished was a restoration of the line of emperors in the West, which 324 years before had been ended by Odoacer, when he dethroned Romulus Augustus and sent the royal vestments to Constantinople (see p. 348). We say this was what he actually effected; for the Greeks of the East, disregarding wholly what the Roman people and the Pope had done, maintained their line of emperors just as though nothing had occurred in Italy. So now from this time on for centuries there were two emperors, one in the East, and another in the West, each claiming to be the rightful successor of Cæsar Augustus. [Footnote: From this time on it will be proper for us to use the terms Western Empire and Eastern Empire. These names should not, however, be employed before this time, for the two parts of the old Roman Empire were simply administrative divisions of a single empire; we may though, properly enough, speak of the Roman empire in the West, and the Roman empire in the East, or of the Western and Eastern emperors. See Bryce's Holy Roman Empire. The Eastern Empire was destroyed by the Turks in 1453; the line of Western Teutonic emperors was maintained until the present century, when it was ended by the act of Napoleon in the dismemberment of Germany (1806).]

CHARLEMAGNE'S DEATH; HIS WORK.—Charlemagne enjoyed the Imperial dignity only fourteen years, dying in 814. Within the cathedral at Aachen, in a tomb which he himself had built, the dead monarch was placed upon a throne, with his royal robes around him, his good sword by his side, and the Bible open on his lap. It seemed as though men could not believe that his reign was over; and it was not.

By the almost universal verdict of students of the mediæval period, Charles the Great has been pronounced the most imposing personage that appears between the fall of Rome and the fifteenth century. His greatness has erected an enduring monument for itself in his name, the one by which he is best known—Charlemagne.
