THE ISMA‘ILIAN SCHISM
name al-Ka’im, ‘he who arises’, a title employed in the literature
of the sect for the real Mahdi, who will arise at the Last Day. The
Sunnite chroniclers denounce him as a cruel atheist, a persecutor
of true Muslims, a more bitter enemy of Islam than the Rumi, or
Byzantines, and relate that devout believers were unable to attend
the mosques on Friday lest they be obliged to listen to prayers for
impious tyrants. A man of vigour, he made Fatimid power feared
all over the Mediterranean: his fleets raided the coasts of France
and Italy and plundered Genoa, and a third attack was made on
Egypt. The cost of this aggressive policy fell heavily on the people:
merchants, peasants and even nomads were taxed severely, and
economic grievances were added to orthodox resentment at heretic
rule. Discontent flared up in the rebellion of Abu Yazid, nicknamed
‘the man on the donkey’, which broke out in 943 in the old
Kharijite lands of the former Rustamid kingdom, and spread all
over North Africa. After some hesitation, the Sunnite jurists of
Kairawan decided that the Kharijites were less odious than the
Isma‘ilis and gave their blessing to the rebels. Ka’im was shut up
in Mahdiya, where he died in 946. His son Mansur, who followed
him, appealed successfully to the loyalty of the Sanhajas, who
relieved Mahdiya, routed the insurgents, and hunted down Abu
Yazid in the mountains of Morocco. The failure of this rising
greatly strengthened the Fatimid regime, and Mansur, after a brief
reign of seven years (946– 953), left a tranquil and prosperous
realm to his son Mu‘izz, the ablest of the Shi‘ite Caliphs.
Under Mu‘izz (953–975) the Fatimids reached the height of their
glory, and the universal triumph of Isma‘ilism appeared not far
distant. The fourth Fatimid Caliph is an attractive character:
humane and generous, simple and just, he was a good
administrator, tolerant and conciliatory. Served by one of the
greatest generals of the age, Jawhar al-Rumi, a former Greek slave,
he took fullest advantage of the growing confusion in the Sunnite
world. A Persian dynasty of Shi‘ite connection, the Buyids, had
seized Baghdad in 945 and reduced the Abbasid Caliphate to
nullity; Egypt had fallen into the hands of a Turkish family, the
Ikhshidids, whose Sudanese troops were terrorizing the population;
an Arab dynasty, the Hamdanids, centred in Mosul, challenged the
Ikhshidids for the possession of Syria, while the Byzantines, under
two vigorous Emperors, Nicephorus Phocas and John Tzimisces,
