[2] He did however confirm all-Mansur in possession of Hama and the surrounding districts, together with scattered towns across Syria - Salamiyah, Maarrat al-Nu'man, Qal'at Najm and Manbij.
[3] As newly installed ruler of Hama, Al-Mansur was expected to maintain a supporting role to the larger Ayyubid domain of Aleppo, ruled by another son of Saladin, az-Zahir Ghazi.
The siege began in May 1201, and after a month Al-Mansur was able to negotiate a peace only by promising to pay Az-Zahir 30,000 dinars and swear obedience to him when and if he succeeded in conquering Damascus.
[9] In May 1203 (Ramadan 599) Al-Mansur secured the assistance of Al-Mujahid of Homs and Bahramshah of Baalbek in an attack on the Crusader County of Tripoli and on the Hospitaller fortress of Krak des Chevaliers from which raids were frequently mounted on Hama territories.
[13] Al Mansur sought help from Al-Mu’azzam in Damascus, but when these reinforcements arrived no further operations occurred, and Al-Mansur was able to negotiate a truce with the Hospitallers.
[14] In 1209-10 Al-Mansur joined Al-Adil in a large campaign to drive back the forces of Queen Tamar of Georgia which were threatening Muslim emirates in eastern Anatolia.
However, as he lay dying some of the leading emirs decided to invite An-Nasr back to Hama to usurp the throne in place of his brother, in the hope that they would be able to exercise real control under his nominal rule.
