Indignant that his efforts for the restoration and maintenance of public order should meet with such a recompense, Ali renounced the statesmanlike policy he had hitherto pursued. The Berbers again reigned supreme in the capital. Once more the streets rang with the tumultuous din of outrage and riot, with the groans of murdered men, with the shrieks of violated women. The tribunals, which for many months had dispensed justice with rigid impartiality, now refused to entertain a complaint against the military tyrants whose passions, exasperated by restraint, raged with redoubled violence. An army of informers was maintained by the government, and eminent citizens were daily consigned to dungeons on the false testimony of the vilest of mankind. This spirit of espionage was so general that it is remarked by a writer, who himself witnessed these scenes, that “one-half of the inhabitants was constantly employed in watching the other half.” The possession of wealth was of itself a powerful incentive to an accusation of treason. A convenient and effective method of replenishing the treasury was devised by causing the arrest of the rich upon fabricated evidence and then restoring them to liberty after payment of an exorbitant ransom. When the friends of the victims came to escort them to their homes, their horses were seized and they were forced to return on foot. It was not unusual for the houses of the nobles to be robbed in open day by the African guards of the Khalif. The few remaining palaces erected by the Ommeyades were destroyed; the known adherents of that faction were persecuted with unrelenting severity, and every conceivable insult was visited upon those whose prejudices against the party in power were assumed to exist by reason of their literary tastes or their superior erudition.

Their ornaments were carried away. Their revenues were confiscated. The ministers of religion were taxed. Many of the finest temples of the capital were deserted or became the haunts of nocturnal marauders. Even the devout dared not assemble for the worship of God. The consciousness of the perfidious ingratitude displayed by his subjects so embittered the temper of the Khalif that he resolved upon the most extreme measures, and publicly announced his intention of razing to its foundation the city of Cordova. The accomplishment of this malignant design, which, in destroying the most splendid architectural monument of Moslem genius, would at the same time have inflicted an irreparable injury upon art and archæology, was fortunately frustrated by the assassination of the tyrant. Three of his most trusted slaves, animated by a desire to liberate their country from the evils from which it suffered, and, so far as can be determined, without the co-operation of others, killed Ali in the bath
