The Fatimid state was essentially an hereditary one, for the Shiʿite theory implied the legitimate descent of the Imam. The recognition of Ismaʿil, the son of Jaʿfar, clearly showed that the father’s claimed right of disposing of the succession was invalid in the eyes of the sect of Seveners. From that time the succession had been strictly hereditary. But the Fatimids, seated in power, borrowed the constitutional usage of the Khalifs of Baghdad, and secured the succession by obtaining formal recognition of the heir during their lifetime. Thus Maʿad was formally recognised as next in succession on Monday, the 7th of Dhu l-Hijja 341, and came to the throne in the following year. In the ʿAbbasid Khalifate this recognition was a relic of the earlier election, and meant that the next Khalif was formally elected by the princes during his predecessor’s lifetime, the orthodox Khalifate not being professedly hereditary. The case was otherwise with the Fatimids who were legitimist, and could only have as Imam the one chosen by God, and to whom alone the Divine Spirit could pass at the preceding Imam’s death. No doubt the formal recognition during the father’s life was adopted as a measure of precaution; theoretically it might be defended by the supposition that its point was the father’s public recognition of his son and heir, but the real case seems to be that it was simply borrowed from the usages of the court of Baghdad, and marks a relaxation of the theocratic and sectarian character of the Fatimid state which is gradually inclining towards becoming a purely secular one, differing from the Baghdad Khalifate in little more than in that it professed Shiʿism as the established religion. VIII THE FOURTH FATIMID KHALIF, AL-MOʿIZZ (A.H. 342-365 = A.D. 953-975) The new Fatimid Khalif was of a type somewhat different from his predecessors. Like them, indeed, he proved an able and efficient ruler, but unlike them he was a man of cultured tastes and of considerable literary ability. His heart was set on the conquest of Egypt, the great dream ever present before his father and grandfather, which seemed now coming within the bounds of possibility.
