Alphonso the Great, king of Asturia, profited by these dissensions the more effectually to confirm his own power. The Normans, from another side, ravaged Andalusia anew. Toledo, frequently punished, but ever rebellious, often possessed local sovereigns. Saragossa imitated the example of Toledo. The authority of the caliphs was weakened, and their empire, convulsed in every part, seemed on the point of dissolution, when Abderamus III., the nephew of Abdalla, ascended the throne of Cordova, and restored for some time its pristine splendour and power, A.D. 912, Heg. 300. {63} This monarch, whose name, so dear to the Moslems, seemed to be an auspicious omen, took the title of _Emir-al-Mumenin_, which signifies _Prince of true Believers_. Victory attended the commencement of his reign; the rebels, whom his predecessors had been unable to reduce to submission, were defeated; factions were dissipated, and peace and order re-established. Being attacked by the Christians soon after he had assumed the crown, Abderamus applied for assistance to the Moors of Africa. He maintained long wars against the kings of Leon and the counts of Castile, who wrested Madrid, then a place of comparative insignificance, from him, A.D. 931, Heg. 319. Often attacked and sometimes overcome, but always great and redoubtable notwithstanding occasional reverses, Abderamus knew how to repair his losses, and avail himself to the utmost of his good fortune. A profound statesman, and a brave and skilful commander, he fomented divisions among the Spanish princes, carried his arms frequently into the very centre of their states, and, having established a navy, seized, in addition, upon Ceuta and Seldjemessa on the African coast. {64} Notwithstanding the incessant wars which occupied him during the whole of his reign, the enormous expense to which he was subjected by the maintenance of his armies and his naval force, and the purchase of military assistance from Africa, Emir-al-Mumenim supported a luxury and splendour at his court, the details of which would seem to be the mere creations of the imagination, were they not attested by every historian of the time. The contemporary Greek emperor, Constantine XI., wishing to oppose an enemy capable of resisting their power, to the Abbassides of Bagdad, sent ambassadors to Cordova to form an alliance with Abderamus.
