the next quarter century. In contrast, Zengi’s seizure of power not only made
Aleppo the political centre of Syria for several decades, but opened a century
which would witness the restoration of the city’s economic fortunes and the
rebirth of its cultural and religious life.

To be sure, Damascus did not always lack for effective rulers in these years.
Tughtigin’s son Taj al-Muluk B

ori (regn. 1128–32) was a worthy but tragically
short-lived successor to his father. His own sons (three of whom succeeded
him as atabeg of Damascus) were not of the same metal, but his widow Safwat
al-Mulk and then the amir Mu
in al-Din Unur, an old mamluk of Tughtigin’s,
successfully defended the independence of Damascus against both the crusaders
and Zengi throughout the late 1130s and 1140s. Upon the death of Unur in 1149,
the government reverted to B

ori’s grandson Mujir al-Din Uvaq (regn. 1140–54),
but he was quickly forced to give way before the rising power of Zengi’s son and
successor in Aleppo, Nur al-Din Mahmud, who occupied Damascus peaceably
in April 1154.
Zengi’s control of Mosul and Aleppo made him the paramount ruler in
Mesopotamia and north Syria.

However, he was able to exploit this opportu-
nity in large part because of his uncommon longevity; he reigned for nineteen
years, until he was assassinated by a disgruntled page in 1146.Zengi was lauded
by Ibn al-Athir (d. 1233), the court historian of the dynasty he founded, as the
first real champion of the jihad against the crusaders, and this judgement was
accepted by western scholars until the 1950s. Since that time, Zengi has usually
been dismissed as just another power-seeking warlord, abler and more cunning
than his contemporaries, perhaps, but most of all luckier, because in 1144 he
seized the great prize of Edessa while its ruler Joscelin II was absent on cam-
paign with most of his army. This judgement understates Zengi’s achievement.
During his two decades of rule, he built a durable and effective political system
which provided at least the basic framework for the more brilliant reigns of his
son Nur al-Din Mahmud and the latter’s general Saladin.
In spite of the obvious military and strategic benefits that he derived from
his control of both Mosul and Aleppo, Zengi faced a difficult challenge in try-
ing to rule two major cities. First, Mosul and Aleppo were separated from each
other by twenty days’ march. Secondly, each belonged to a distinct if overlap-
ping geopolitical system. Mosul always had to deal with the Great Seljuqids in

Zengi was not atabeg in name only: Mosul was the appanage of Sultan Mahmud’s infant son Alp
Arslan, and Zengi held office as his guardian and tutor. Alp Arslan tried to take advantage of the
confusion following Zengi’s sudden demise in 1146 to reclaim his principality for himself. He failed,
however, and was quickly heard of no more. Alp Arslan was the last Seljuqid prince of Mosul;
henceforth, Zengi’s heirs would hold it in their own name. Eliss
