مناقلة حلب من الموصل إلى سنجار

In Rajab 577 AH al-Malik al-Salih Isma'il ibn Nur al-Din died in Aleppo. He had willed its handover to his cousin Izz al-Din Mas'ud, lord of Mosul, and Izz al-Din entered it on the twentieth of Sha'ban. The matter then ended in an exchange: Imad al-Din took Aleppo and handed Sinjar to his brother. ¹

Taqi al-Din Umar fled from Manbij to Hama, and the people of Aleppo rose behind Izz al-Din's banner. The army of Aleppo advised Izz al-Din to march on Damascus, but he refused and said that he had an oath between himself and Salah al-Din. ¹

Imad al-Din then asked for Aleppo in exchange for Sinjar, and threatened to hand Sinjar over to Salah al-Din. The emirs advised handing it over, and Mujahid al-Din Qaymaz was the most insistent, out of fear of Izz al-Din's greatness in his own eyes, as Ibn al-Athir relates. So Izz al-Din returned to Mosul. ¹

Salah al-Din in Egypt had found Izz al-Din's rule over Aleppo a burden. When news reached him that Imad al-Din had taken it, he set out for Syria the same day. ¹
