1149 CE
The possessions of the late Zengi had been divided between his sons: Nur ad-Din had received Aleppo and Saif ad-Din Ghazi Mosul, while Qutb ad-Din Mawdud had received the emirate of Homs.
After the death of Saif ad-Din Ghazi in 1149, Qutb ad-Din Mawdud is the first to arrive in Mosul and have himself recognized as emir; Nur ad-Din, who desires to add the city to his lands, occupies Homs and Sinjar, preparing to attack his brother.
Only the intervention of veterans of the Aleppo army, who refuse to take part in the fratricidal war, which would only weaken the effort against the Crusaders and the emirate of Damascus, forces Nur ad-Din to renounce the expedition and to reconcile with his brother.
