This famous gift may be regarded as having laid the basis of the temporal power of the Popes; for though Pepin probably did not intend to convey to the Papal See the absolute sovereignty of the transferred lands, after a time the Popes claimed this, and finally came to exercise within the limits of the donated territory all the rights and powers of independent temporal rulers. So here we have the beginning of the celebrated _Papal States_, and of the story of the Popes as temporal princes. ACCESSION OF CHARLEMAGNE.--Pepin died in the year 768, and his kingdom passed into the hands of his two sons, Carloman and Charles; but within three years the death of Carloman and the free votes of the Franks conferred the entire kingdom upon Charles, better known as Charlemagne, or "Charles the Great." HIS CAMPAIGNS.--Charlemagne's long reign of nearly half a century--he ruled forty-six years--was filled with military expeditions and conquests, by which he so extended the boundaries of his dominions, that at his death they embraced the larger part of Western Europe. He made fifty-two military campaigns, the chief of which were against the Lombards, the Saracens, and the Saxons. Of these we will speak briefly. Among Charlemagne's first undertakings was a campaign against the Lombards, whose king, Desiderius, was troubling the Pope. Charlemagne wrested from Desiderius all his possessions, shut up the unfortunate king in a monastery, and placed on his own head the iron crown of the Lombards. While in Italy he visited Rome, and, in return for the favor of the Pope, confirmed the donation of his father, Pepin (774). [Illustration: CHARLEMAGNE.

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.
