THE BREAKUP OF THE CALIPHATE
descendant of the martyred Husain, as his heir but the opposition
to this plan was so violent that he was obliged to abandon it.
Mutawakkil, a dour bigot, was bitterly hostile to Alid pretensions,
and in 851 the shrine of Husain at Karbala was destroyed at his
orders, the site ploughed up, and pilgrimages to the place
forbidden. For a time the Alid movement died down, only to burst
afresh in a more furious form in the Isma‘ilian uprising at the close
of the century. The Alids failed to displace the Abbasids, but they
kept the Empire in a state of constant disturbance and contributed
not a little to its ultimate disintegration.
A third religious danger was represented by the Manichaean and
millenarian sects of Persia and Iraq. A Manichaean preacher was
put to death as early as 742, in Omayyad times: a generation later
the Caliph Mahdi (775–785) instituted a rigorous inquisition
designed to extirpate the zindiks, infidels or heretics, as the dualists
had come to be known, as a result of which they were driven
eastwards into the Turkish lands of Central Asia. The revival of
Persian national sentiment in the eighth century was accompanied
by a series of fanatical outbreaks, some harking back to the
Mazdak affair of Sassanid days, some inspired by the career and
memory of Abu Muslim, who after putting the Abbasids on the
throne, had been treacherously slain by Mansur in 754 for fear of
his growing power. Abu Muslim had himself put to death in 749
an agitator named Bih-afaridh who claimed to have received divine
revelations and commanded his followers to worship the sun, but
after his own murder it was widely believed that he had merely
disappeared and would return to punish his foes. Among those who
looked for his second coming were the Rawandis (so-called from
Rawand, a village near Isfahan), who taught the transmigration of
souls. In the reign of Mahdi, Khurasan was thrown into disorder
by the appearance of Mukanna, the ‘Veiled Prophet’ celebrated in
Moore’s Lalla Rookh. Masked in green silk, to hide the brightness
of his face according to his followers, to conceal his deformities
according to his enemies, he claimed to be the manifestation of
God, revived the doctrines of Mazdak, and beat back the armies
sent against him until 780, when he was besieged in a castle where
he had taken refuge, and burnt himself to avoid falling into the
hands of the Caliph’s troops. In 817, under Ma’mun, another
prophet named Babak or Papak rose up in Azerbaijan, leading a
