Zengid dynasty
During his caliphate, the Crusades were raging and Zengi, the atabeg of Mosul and founder of Zengid dynasty, obtained high distinction as a brave and generous warrior. At one time hard pressed, Zengi made urgent appeal for help to Baghdad. The sultan and the caliph dispatched 20,000 men in response. But in reality neither the Seljuks, nor the caliph, nor their emirs, had any enthusiasm for war against the Crusaders.
