The research deals with the biography of a king from the kings of the Levant Bilad Al-Sham during the Ayyubid Al-Aywbya era, specifically between the two years (575-617 AH) (1179-1220 AD). It is the Mansur king Muhammad ibn Taqi Al-Din Omar king of Hama, who during this era has written stances and championships that require to ponder over them, especially after crowning the king of Hama after the death of his father in the year (587 AH/ 1191 AD), and he had charts and tours in dealing with the campaigns of the Crusaders during his reign, as the Crusader armies went to his country more than once, during which he was able to confront those attacks and inflict heavy losses on the Crusaders until they realized the power of Hama and the difficulty of exposure to it, and the first of these attacks was in the year (599 AH/ 1203 AD), when a large force of the most powerful crusader teams known (Hospitalism) went to the city of Barin, the southern gate of the city of Hama, and they tried to get through it to the city of Hama, but the Mansur king managed to confront this attack and caused heavy losses in lives and equipment in addition to capturing those from the families of the attacking force, then the attack was repeated in the same year in a desperate attempt to take the revenge of the previous defeat, but this time the defeat was greater and more severe than the previous one. This is the biggest thing that forced the Crusaders to resort to diplomatic methods, demonstrating their desire for the reconciliation that took place. After the expiry of the reconciliation period in the year (601 AH/ 1205 AD), the Crusaders took advantage of the lack of readiness of the Hama army, and suddenly attacked the city of Hama, which led to losses among the people of Hama and the capturing of prisoners, but the intention of King Al-Mansour saved the situation once again by his steadfastness and his confrontation of the attacking force according to the description of historians, and after this defeat, the King Mansour managed to reduce the burden of the defeat by retrieving the captives from the two Crusaders through diplomatic means.
