authority had wholly or partially superseded that of the previous sovereigns of
Islam.
Despite this Shi
ite supremacy, the Shiite victory was precarious. Shiism
itself had barely emerged as a religious doctrine out of widespread political
loyalty to the
Alids or Alawis, the descendants of Ali who laid claim to rule
as the Prophet’s closest kin. In so far as it had done so, it was riven by the
disagreement of the Seveners and the Twelvers over the identity of the imam
whose religious authority was central to their faith. The Fatimids’ impressive
rise from revolution to empire had convinced a variety of Shi
ites right across the
Islamic world of the truth of their claim to the imamate in line of descent from
Ali’s younger son Husayn, through the figure of Muhammad ibn Ismail, the
Seventh Imam with whom the line had passed into satr or concealment at the
end of the eighth century, before its reappearance in the person of the Fatimid
mahdi in North Africa in 910.

But this claim was disputed by the Twelvers, who
did not recognize the imamate of Muhammad ibn Isma
il, and by many Alids
who challenged the whole of the Fatimid genealogy. While Shi
ites thus divided
their loyalties between alternative, even multiple claimants to the authority
of God on earth,
3
their opponents not only included established monarchs
threatened by the principle of
Alid rule, beginning with the Abbasids but
extended to dynasties on the periphery of the Islamic world, most notably the
Umayyads in Spain and the Ghnaznavids in eastern Iran. The majority of the
men of religion objected less to Shi
ite claims to power than to Shiite claims
to authority over the Shari
aorIslamic Law. Whereas most jurists claimed
to follow the Sunna or exemplary custom of the Prophet as preserved by the
collective scholarship of successive generations of students and teachers, Shi
ites
had come to regard their chosen imam as the sole guarantor of the authenticity
of this Prophetic tradition from generation to generation. When, as in the
case of the Fatimids, the chosen imam who laid down the Law was also the
monarch who enforced it, the conflict between Shi
ites and the Sunni majority,
who relegated the ruler to the executive arm of the Law, was not only doctrinal
but political.

It was made all the more acute by the Mahdism of the Fatimids,
by their belief in their messianic mission to revive the faith after its lapse into
ignorance on the part of the faithful, which had brought their dynasty to power
in North Africa and Egypt. The Buyids, who laid no claim to religious authority
themselves, were more modest, seeking only a niche for themselves as barbarian
intruders upon the imperial Arab scene. The lines of battle were nevertheless
sharply drawn; and despite the political success of Shi
ism, the obstacles to its
