BIOGRAPHICAL DOSSIER
Life and historical role
Life and political setting
Unur was a Turkish commander trained among Toghtekin's mamluks. After 1138 he effectively governed Damascus on behalf of the Burid rulers. Against Imad al-Din Zengi's attempts to take Damascus, he allied with King Fulk of Jerusalem in 1140.
Role in the Crusades
In July 1148 the armies of Louis VII, Conrad III and Baldwin III besieged Damascus. Unur organised the city's defence, asked Nur al-Din and Sayf al-Din Ghazi for help, and at the same time conducted secret negotiations with the barons of Jerusalem. After the crusaders moved their camp, the siege ended within days.
Historical significance and source problems
Unur tried to preserve the independence of Damascus by balancing between Jerusalem and the Zengids, and died in 1149. The claim that Unur bribed the crusaders to withdraw appears in Latin sources but cannot be verified. Ibn al-Qalanisi describes the siege from inside the city.
