تتش بن ألب أرسلان
After the death of Tutush I in 1095, Syria was divided between his sons Abu Nasr Shams al-Muluk Duqaq and Fakhr al-Mulk Radwan. Duqaq took control of Damascus while Radwan established himself as ruler of Aleppo. During Duqaq's reign (1095–1104), additional work was carried out on the citadel. In 1096, Radwan besieged the citadel but failed to capture it.
