THE MONGOL DISASTER
The Mongol army, in composition more Turkish than Mongol,
and including contingents from the Christian kingdoms of Armenia
and Georgia, was probably the largest, best equipped and best
disciplined that had ever issued from the steppes of Central Asia.
Hulagu first moved against the Assassins, who though they had
never succeeded in creating a territorial State, had resisted all
efforts to dislodge them from their castles in northern Persia. He
demanded their submission and the dismantling of their
strongholds. The reigning Imam, Muhammad III, a moody
melancholic, favoured defiance, but his chiefs were terrified of
Mongol strength and ferocity, and had him killed in a drunken
sleep. His son Rukn al-Din, the last ‘grand master’ of Alamut,
young, inexperienced and frightened, gave in; the Mongols
swarmed into the Assassin fortresses, and such local or sporadic
defence as was put up was savagely crushed. Rukn al-Din asked
to be sent to the Great Khan; but Mongke refused to see him, and
on the road back from Mongolia he was slain by his guards.
Sunnite Islam might rejoice in the extermination of the Isma‘ili
terrorists, but Hulagu cared nothing for the distinctions between
Muslims and turned next against Baghdad. Since the death of Nasir
in 1225, the Abbasids had sunk again into lethargy under his
incompetent successors, and the Caliph Musta‘sim (1242–1258), the
last Commander of the Faithful, was the man least likely to lead a
holy and heroic fight against the hordes of paganism. Confronted by
the usual Mongol demand for surrender, he temporized, desperately
hoping that the Muslim princes would rally to the defence of their
spiritual chief. Hulagu, growing impatient, commenced military
operations; his army crossed the Tigris and besieged the city; his
engineers broke the dykes and flooded the Muslim camp; the
inhabitants, panic-stricken, tried to flee, many being caught and
drowned in the rising floodwaters, and the unhappy Musta‘sim in
despair sent the Nestorian Patriarch to the enemy to offer capitulation.
Hulagu ordered the Caliph to come in person to his camp, with his
family and retinue, to tell his people to stop fighting, and to give up
his wealth and treasure. His commands were obeyed, and the
metropolis of Islam was abandoned to the merciless bloodlust of the
conquerors. The palaces, colleges and mosques were plundered and
burnt; the cultural accumulation of five centuries perished in the
flames, and the appalling figure of 800,000 is the lowest estimate given
