The Saracens had been expelled from France by the grandfather and father of Charlemagne; but they still possessed the greatest part of Spain, from the rock of Gibraltar to the Pyrenees. Amidst their civil divisions, an Arabian emir of Saragossa implored his protection in the diet of Paderborn. Charlemagne undertook the expedition, restored the emir, and, without distinction of faith, impartially crushed the resistance of the Christians, and rewarded the obedience and services of the Mahometans. In his absence he instituted the Spanish march, 108 which extended from the Pyrenees to the River Ebro: Barcelona was the residence of the French governor: he possessed the counties of Rousillon and Catalonia; and the infant kingdoms of Navarre and Arragon were subject to his jurisdiction. III. As king of the Lombards, and patrician of Rome, he reigned over the greatest part of Italy, 109 a tract of a thousand miles from the Alps to the borders of Calabria. The duchy of Beneventum, a Lombard fief, had spread, at the expense of the Greeks, over the modern kingdom of Naples. But Arrechis, the reigning duke, refused to be included in the slavery of his country; assumed the independent title of prince; and opposed his sword to the Carlovingian monarchy. His defence was firm, his submission was not inglorious, and the emperor was content with an easy tribute, the demolition of his fortresses, and the acknowledgement, on his coins, of a supreme lord. The artful flattery of his son Grimoald added the appellation of father, but he asserted his dignity with prudence, and Benventum insensibly escaped from the French yoke. 110 IV. Charlemagne was the first who united Germany under the same sceptre. The name of Oriental France is preserved in the circle of Franconia; and the people of Hesse and Thuringia were recently incorporated with the victors, by the conformity of religion and government. The Alemanni, so formidable to the Romans, were the faithful vassals and confederates of the Franks; and their country was inscribed within the modern limits of Alsace, Swabia, and Switzerland. The Bavarians, with a similar indulgence of their laws and manners, were less patient of a master: the repeated treasons of Tasillo justified the abolition of their hereditary dukes; and their power was shared among the counts, who judged and guarded that important frontier. But the north of Germany, from the Rhine and beyond the Elbe, was still hostile and Pagan; nor was it till after a war of thirty-three years that the Saxons bowed under the yoke of Christ and of Charlemagne. The idols and their votaries were extirpated: the foundation of eight bishoprics, of Munster,
