With Motassem, the eighth of the Abbassides, the glory of his family and nation expired. When the Arabian conquerors had spread themselves over the East, and were mingled with the servile crowds of Persia, Syria, and Egypt, they insensibly lost the freeborn and martial virtues of the desert. The courage of the South is the artificial fruit of discipline and prejudice; the active power of enthusiasm had decayed, and the mercenary forces of the caliphs were recruited in those climates of the North, of which valor is the hardy and spontaneous production. Of the Turks who dwelt beyond the Oxus and Jaxartes, the robust youths, either taken in war or purchased in trade, were educated in the exercises of the field, and the profession of the Mahometan faith. The Turkish guards stood in arms round the throne of their benefactor, and their chiefs usurped the dominion of the palace and the provinces. Motassem, the first author of this dangerous example, introduced into the capital above fifty thousand Turks: their licentious conduct provoked the public indignation, and the quarrels of the soldiers and people induced the caliph to retire from Bagdad, and establish his own residence and the camp of his Barbarian favorites at Samara on the Tigris, about twelve leagues above the city of Peace. His son Motawakkel was a jealous and cruel tyrant: odious to his subjects, he cast himself on the fidelity of the strangers, and these strangers, ambitious and apprehensive, were tempted by the rich promise of a revolution. At the instigation, or at least in the cause of his son, they burst into his apartment at the hour of supper, and the caliph was cut into seven pieces by the same swords which he had recently distributed among the guards of his life and throne. To this throne, yet streaming with a father's blood, Montasser was triumphantly led; but in a reign of six months, he found only the pangs of a guilty conscience. If he wept at the sight of an old tapestry which represented the crime and punishment of the son of Chosroes, if his days were abridged by grief and remorse, we may allow some pity to a parricide, who exclaimed, in the bitterness of death, that he had lost both this world and the world to come. After this act of treason, the ensigns of royalty, the garment and walking-staff of Mahomet, were given and torn away by the foreign mercenaries, who in four years created, deposed, and murdered, three commanders of the faithful. As often as the Turks were inflamed by fear, or rage, or avarice, these caliphs were dragged by the feet, exposed naked to the scorching sun, beaten with iron clubs, and compelled to purchase, by the abdication of their dignity, a short reprieve of inevitable fate. At length, however, the fury of the tempest was spent or diverted: the Abbassides returned to the less turbulent residence of Bagdad; the insolence of the Turks was curbed with a firmer and more skilful hand, and their numbers were divided and destroyed in foreign warfare.
