Whilst in exile and in Hamdanid’s hands, the Khalif appealed to the Ikhshid whom he had set over Egypt, and Muhammad visited him at Riqqa and invited him to take refuge in Egypt; but al-Muttaqi, though anxious for help to recover the external symbols of authority at Baghdad, was not willing to put himself so entirely in the Ikhshid’s hands; he knew that Ikhshid and Hamdanid alike only desired to possess his person as a kind of imperial regalia, and so he preferred to entrust himself to the Turk Tuzun, who at least could establish him in the capital. He reigned in Baghdad in name only until 333, when Tuzun deposed him, put out his eyes, and enthroned al-Mustakfi in his place. But this was followed by a period of anarchy in Baghdad, until in 334 the Buwayhid prince took the city. A few months later al-Mustakfi was deposed and replaced by al-Muʿti, whose position under the Buwayhid princes was parallel to that of the Frankish kings under the “Mayors of the Palace,” with the aggravated condition that the Khalifs were spiritual pontiffs and the Buwayhids were, like the Hamdanids, Shiʿite heretics of the “Twelvers” sect. Buwayhid’s rule over Baghdad lasted from 384 to 447, when the Emir was displaced by the Saljuk Turks under Tughril Beg. Throughout this period the Buwayhids were content with the title of _Emir al-Umara_; they never assumed that of Sultan. It has been necessary for us to turn aside to note the position of the Khalifate at the time, for otherwise we should have some difficulty in understanding the course of events in Egypt, which now takes the foremost place in the policy of the African Shiʿites. It is often possible to ignore the contemporary history of Spain and of North Africa when following the course of events in Egypt, but Egypt forms so integral a part of the world of Islam that it is never possible to treat its history, even during the comparative isolation of the Fatimid period, without some passing note of the contemporary history of the Baghdad Khalifate. Whilst these changes were taking place in Asia and the Ikhshid was consolidating his power in Egypt, the Mahdi continued ruling at Kairawan, and, though North Africa was one of the most turbulent and the least civilized parts of the Islamic world, his rule was stable and orderly. In 312 he added a suburb to the city which he called al-Muhammadiya, and which served as a kind of royal cantonments closed against the ordinary citizens, and used only as an official settlement of those engaged in the public administration and as the site of the various public offices. Such official suburbs were very frequent in oriental capitals, and become a regular feature of the great Muslim royal cities. The Mahdi’s later years were somewhat clouded by his relations with the Qarmatians, who were still active in Asia, and who caused the whole Ismaʿilian movement to be regarded with grave suspicion by the Muslim world at large.
