THE
SALJUQ COUNTEROFFENSIVE
was
held responsible for Isma'ili attacks on amirs who opposed him,
he was himself attempted by assassins when he appointed a vizier
who
was strongly anti-Isma'ili. In
494/1101,
Berk-Yaruq in western
Iran
and Sanjar in Khurasan came to an agreement to regard the
Isma'ilis no longer as local bands but as a general
threat
to Saljuq
power,
and to act against them. The
chief
fruit of Berk-Yaruq's
resolve
was a grand massacre of suspected Isma'ilis at Isfahan, Baghdad,
and elsewhere. Army officers were especially affected and several of
them fled. Sanjar, with fewer friends of the Isma'ilis to purge within
his own ranks, sent instead an expedition against Tabas in Kuhistan,
which
was said to have been bought
off
after causing much devastation;
and
three
years later he sent another which wrecked Tabas and de-
stroyed as much else as possible. The second expedition, as a jihad
(holy
war), was joined by many Sunni volunteers in addition to the
regular troops, and the Isma'ili captives, as apostates, were enslaved.
Yet
the next year Isma'ilis from Turshiz in Kuhistan were in a position
to raid a Sunni caravan as far west as Ray; and in Berk-Yaruq's lands
no Isma'ili fortresses seem to have been overthrown at all.
Meanwhile,
the Isma'ili position was being consolidated in Rudbar,
where several other fortresses were aligned with Alamut, apparently
in many cases by agreement with the local leaders, who received aid
from
the Isma'ilis against domination from Ray and Qazvin. The most
important addition was Lanbasar, considerably west of Alamut in
the
Shahrud
valley.
After its garrison went back on their first agree-
ment with the Isma'ilis, it was re-subjugated by Hasan's lieutenant
Buzurg-Ummid
and built into a major stronghold. In Syria in this
period the Isma'ilis controlled as yet no fortresses, but they were strong
in Aleppo and in the nearby towns of the
Jazr
region, and they enjoyed
the patronage of Ridwan, Saljuq amir of
Aleppo.
With
the advent to power of Muhammad Tapar, however, the more
important dynastic disputes ended and the Saljuq forces made greater
headway
against the Isma'ili revolt. Even in Syria, Ridwan
turned
gradually
against the Isma'ilis, who had become embarrassing, and he
allowed
more
than
one massacre of them; on his death in
507/1113,
they were scattered from their headquarters in Aleppo and for some
time sought vainly a citadel which they could hold for their own. Most
of
the Isma'ili strongholds in the Zagros mountains seem to have
fallen
during Muhammad's reign. In 500/1107 Muhammad sent an
expedition
against Takrit; to avoid letting it fail into his hands, its
