Imad ad-Din Zengi
A large portion of the history deals with the era of the Crusades; this portion has been translated by D. S. Richards in three volumes, dealing with the arrival of the crusaders up to the time of Imad ad-Din Zengi, Nur ad-Din, and Saladin. In fact, ibn al-Athir's portrayal of the advent of the crusades is especially informative of the Muslim perspective of the beginning of the Crusades.
