The disintegrated sections of the empire were now to witness the trial of a form of government hitherto unknown to the Moslem constitution. The very essence of the polity of Islam had always been the concentration of power in a single individual, who exercised conjointly the functions appertaining to the official head of both Church and State. The assumption of authority by an association of nobles, while the result of political necessity, was none the less an act of flagrant usurpation. It was repugnant to the principles, the traditions, the legal and religious maxims upon which the organization of Moslem society was based, and by which it had always been maintained. It had not received the sanction of popular approbation or consent. The dethronement of Hischem was an arbitrary deed of violence unconfirmed by any evidence of voluntary abdication. As there had been no formal renunciation of vested rights, those rights were only suspended, and the subjects of the Khalif were not, in law, absolved from their allegiance. The constitution of the Council of State, whose jurisdiction extended but a short distance beyond the walls of Cordova, was partly oligarchical and partly democratic. A formal assemblage of citizens conferred upon Ibn-Djahwar, the most prominent member of that body, an office whose powers and privileges appertained to the anomalous dignity of the autocratic supreme magistrate of a republic. The course of Ibn-Djahwar was characterized by the greatest moderation and justice. Unlike the Cæsars of Rome, whose despotic edicts were registered by an obsequious senate, the president of the Moorish Council of State refused, of his own volition, to decide or even to examine any question until it had been publicly presented to his associates, and he required that all official communications should be addressed to them. This habitual deference to the opinions of his colleagues, which, however, invariably coincided with his own, increased the consideration in which he was held by the nobility, the army, the clergy, and the people. The new magistrate, in addition to the eminent qualifications which both suggested and justified his promotion, was aided by many adventitious circumstances which rarely fail to elicit the admiration or the homage of mankind. He belonged to a family of ancient and distinguished lineage. His ancestors had served the khalifs in the departments of finance and war. He was the most opulent citizen of the capital, and had managed, by an exercise of thrift and economy unusual in his station, to make vast accumulations to his wealth without ever incurring the suspicion of corruption or tyranny. The measures he adopted for the public welfare were dictated by the most exemplary prudence and wisdom. Taxes were reduced. Mercantile enterprise was promoted by the assurance of public security, derived from the protection of the highways and the repression of crime. Intimate commercial relations were established
