At the death of Clovis in 511, his four sons divided the kingdom, which was afterwards reunited, divided again, and again united, amidst scenes of tumult and bloodshed. The line of kings proceeding from Clovis (called Merovignian from his grandsire Meroveus) dwindled in time into utter insignificance, while the chief power was wielded by an important officer, called the Mayor of the Palace. Among the most remarkable of these was Pepin Heristal, Duke of Austrasia, who ruled France for thirty years with great wisdom and good policy. His son, Charles Martel, who succeeded to his power, distinguish himself by that great victory over the Saracens (A. D. 732), which checked their career in Europe. An appeal by Pepin le Bref, the son of Charles Martel, to the pope of Rome, whose authority had by this time become great, ruled that he who had the power should also have the title of king, and this put an end to the reign of the descendants of Clovis (752). Pepin remunerated the pope for this service by turning his arms against the Lombards in Italy, some of whose dominions he conferred upon the Holy See; and these, it is said, were the first of the temporal possessions of the church. Pepin died (768), leaving two sons, Carloman and Charles, who succeeded him in the empire. Carloman died at an early period of life, but Charles (subsequently Charlemagne) survived to achieve for himself a fame far greater than that of any other individual during the middle ages, with perhaps the single exception of Mohammed. We shall proceed to speak of him and of his times, after making one or two observations on some other European countries. Spain was among the earliest countries lost to the Roman Empire. From about the year 406, this country, in whole or in part, had been successively invaded and subdued by Suevi, Alans, Vandals, and Visigoths. The last-named people were in possession of the greater part of the country before the year 585, and erected a monarchy which existed till 712, when they were subdued by the Saracens or Moors. The Saracens made their descent on Spain from Africa, where Nuza, a viceroy of the caliph of Bagdad, had already made extensive conquests. They easily overran Spain and vanquished Don Rodrigo, or Roderic, the last of the Gothic kings. Abdallah, son of Muza, married the widow of Roderic, and the two nations entered into union. Before the conclusion of the eighth century, Abdalrahman, one of the Moorish generals, had laid aside all temporal subjection to the caliph of Bagdad, and formed Spain into an independent kingdom. His residence was at Cordova, and this city became renowned as one of the most enlightened in Europe under several succeeding reigns. Those parts of Spain which were under the Moorish kings embraced also their religion. The northern provinces never owned their dominion.
