Nur ed din was in Aleppo and Shirkuh at Emesa. Nur ed din, however, at no time indifferent to the importance of gaining influence and power, gave two hundred thousand gold ducats to Shirkuh and sent him to Egypt immediately (December, 1168). Six thousand chosen Syrians marched with him and two thousand picked Turkman warriors from Damascus. Saladin, urged by his uncle, accompanied the expedition. Meanwhile Shawer and Amalric were negotiating—the former to liberate, the latter to win Cairo. Shawer promised a million of ducats in the name of the Kalif, and the King of Jerusalem was glad to receive fifty thousand in ready money. The Crusaders withdrew when the Syrians under Shirkuh appeared before Cairo in January, 1169. The Kalif went to the camp on a visit immediately, and complained very bitterly of Shawer who had brought the Crusaders into Egypt, burned Fustat, and ruined the country. He begged Shirkuh to obtain for him the head of the vizir, he himself being unable to get it. Shawer felt now his own danger, and, while feigning friendship for the Syrians, resolved to destroy, under cover of a banquet, both Shirkuh, and Saladin, his nephew, with the princes of their suite. The plot became known in good season, however, and when Shawer was approaching on a visit to Shirkuh, he was seized and killed, and his head was sent to the Kalif. Shirkuh took Shawer’s place as vizir and the Kalif gave him the title of Al Melik Al Mansur (The Victorious King). Shirkuh died two months later, March 26, and his nephew Yussuf Salah ed din, now thirty-one years of age, was invested with the same dignities of office and received the same title. Saladin was now the vizir of the Kalif, and Nur ed din’s commander, thus his position was peculiar; he was the vizir of a Shiite Kalif and the commander of a Sunnite king. He therefore caused the name of Nur ed din to be mentioned in public prayers every Friday after that of the Kalif, Nur ed din thought that the time had come to abolish the Fatimid Kalif at, but Saladin delayed since the people clung to Adhad, the last representative of the dynasty. Adhad fell ill, however, and died opportunely. Saladin transferred the prerogative of prayer then from the Fatimid line to that of the Abbasid September 10, 1171. In this way Saladin delivered the blow which destroyed the main branch of the Western Ismailites. The Abbasid Kalif at now prevailed over that of the family of Ali for which the Ismailites had taught and conspired and in whose name they had deceived the people for nearly three centuries. This was an event of vast importance in the history of the East, as well as in that of the Assassin Order before whom Saladin, now a famous warrior and an ardent champion of the Abbasids, stood forth as a powerful and dangerous enemy.
