Rumours about the plans of Tancred's successor, Roger of Salerno, to conquer Aleppo brought about an alliance between the Artuqid emir of Mardin, Ilghazi, and the atabeg (or governor) of Damascus, Toghtekin, in the early summer of 1119.
[20][21] Therefore, he made an alliance with Joscelin I of Edessa, a Bedouin leader, Dubais ibn Sadaqa from Banu Mazyad and two Seljuq princes, Sultan Shah and Toghrul Arslan.
[20] In the meantime, the qadi of Aleppo, Ibn al-Khashshab, approached Aqsunqur al-Bursuqi, atabeg of Mosul, seeking his assistance.
[22] Upon hearing of al-Bursuqi's arrival, Dubais ibn Sadaqa withdrew from Aleppo, which forced Baldwin to lift the siege on 25 January 1125.
[23][24] Baldwin II and al-Bursuqi forces met at the Battle of Azaz in June 1125, which resulted in a crusader victory.
