The nomad tribe of Turkomans had made themselves masters of Khorassan, and determined upon the election of a king. Toghrul Beg, a grandson of a noble chief named Seljuk, was chosen by lot for the office, and in a short time extended his conquests over the whole of Persia; and, being a rigid Mohammedan of the orthodox sect, compelled the revolted lieutenants of the Abbasside caliphs to return to their allegiance. For this service he was named Emir el Omará (“Chief of chiefs”), and appointed the vicegerent and protector of the caliph. His nephew, Alp Arslán, succeeded him, and, after a brilliant career of conquest, left the sceptre to his son Melik Shah (A.D. 1072). This prince, a worthy scion of the Seljukian line, resolved upon the extension of the Fatemite dynasty, and the establishment of his own authority in Syria and Egypt. His lieutenant, Atsiz, a native of Kh’árezm, invaded the former country, and took possession of Ramleh and Jerusalem—the latter after a protracted siege. The names of the Abbasside caliph, and of the Sultán Melik Shah, were now formally substituted for that of the Egyptian caliph, El Mostanser Billah, in the Friday Khotba, at the Masjid el Aksa. Five years later he besieged Damascus, and the capital of Syria also fell before his troops: the inhabitants, already reduced to the last extremities by famine, were punished for their resistance by the resentful Emír, and the city being given up to pillage, the most frightful scenes of carnage ensued. Emboldened by this victory, he marched upon Egypt at the head of a large army of Turkomans, Kurds, and Arabs, and laid siege to Cairo. Here, however, he was repulsed with considerable loss, and compelled to return to Syria, which he found already in a state of insurrection against his authority. Those of his troops who had escaped slaughter in Egypt were butchered by the insurgents as they passed Palestine; and Atsiz, accompanied only by a small band of adherents, escaped with difficulty to Damascus, where his brother had been left at the head of affairs during his absence. Jerusalem had, in the meantime, risen against the Turkish chief; but the insurrection was soon quelled, and the Cadhí and other municipal officers, together with three thousand of the inhabitants, were put to death. Atsiz was shortly afterwards besieged in Damascus by the Egyptian forces, and called in to his aid the Emír Tutush, a son of Alp Arslan. The Egyptians fled without attempting to oppose the advancing army, and Emír Tutush was welcomed by Atsiz at the city-gate. Jealous, doubtless, of his subordinate’s previous victories and growing influence, the prince commanded him to be seized and executed upon the spot,—alleging, as an excuse for the barbarous act, that the general had been wanting in respect, and had not awarded him the reception to which his rank entitled him. The Emir Tutush now assumed the post of governor-general of Syria, and assigned that of
