The disorders of the unhappy Peninsula had, however, become incurable under the present conditions of government. All the skill and experience of Yusuf were exhausted in fruitless attempts at the adjustment of territorial disputes and the pacification of feuds which a generation of internecine conflict had engendered. An insurrection broke out in Septimania, a province hitherto exempt from similar disturbances. Ahmed-Ibn-Amru, wali of Seville, whom Yusuf had removed from the command of the fleet, a chief of the Koreish, whose vast estates enabled him to surpass the magnificence of the Emir himself, and an aspirant for supreme power, organized and headed a formidable conspiracy. His name was associated with the early triumphs of Islam, for he was the great-grandson of the ensign who had borne the standard of Mohammed at the battle of Bedr. Prompted by unusual audacity, which was confirmed by the possession of wealth, ability, and power, he asserted that he had received the commission of the Abbasides as Viceroy of Spain. The Asturians, emboldened by the quarrels of their foes, leaving their mountain fastnesses, began to push their incursions far to the southward. The entire country was engaged in hostilities. Every occupation but that of warfare was suspended. The herdsman was robbed of his flocks. The fertile fields were transformed into a barren waste. On all sides were the mournful tokens of misery and want; from palace and hut rose the moan of the famishing or the wail for the dead. Intercourse between the neighboring cities, alienated by hostility or fearful of marauders, ceased. The doubtful tenure of authority, dependent upon the incessant changes of administration, made it impossible for the Christians to ascertain to whom tribute was rightfully due. and this confusion of interests often subjected them to the injustice of double, and even treble, taxation. At no time in the history of Spain, since the irruption of the Goths, had such a condition of anarchy and social wretchedness prevailed; when the inspiration of a few Syrian chieftains brought the existing chaos to an end, by the introduction of a new ruler and the re-establishment of a dynasty whose princes, the tyrants of Damascus, had hitherto reflected little more than odium and derision on the Moslem name.
