Al-ÿAzëz ÿUthmÃÂn ibn al-ÿÃÂdil (died 20 June 1233) was the Ayyubid ruler of Banyas from 1218 until his death.
Al-ÿAzëz ÿUthmÃÂn was a younger son of Sultan al-ÿÃÂdil I. He was granted Banyas as an iqá¹ÂÃÂÿ (fief) by his elder brother, al-MuÿaáºÂáºÂam, perhaps in 1218. In 1219, with ÿIzz al-Dën Aybak, he was left in charge of al-MuÿaáºÂáºÂam's Syrian principality when the latter went to join the Sultan al-KÃÂmil in Egypt against the Fifth Crusade. When al-MuÿaáºÂáºÂam decided to raze the walls of Jerusalem, he protested unsuccessfully that he was able to defend the city. After al-MuÿaáºÂáºÂam dismantled all of his fortresses west of the Jordan River, he gave the territory to al-ÿAzëz ÿUthmÃÂn. This included the former crusader castles of Beaufort, Chastel Neuf and Toron.
During the Sixth Crusade, in February or March 1228, al-ÿAzëz ÿUthmÃÂn ambushed a group of crusaders near Tyre. He killed or captured some seventy horsemen in one of the few military actions of the crusade. Later that year, he entered a conspiracy to seize Baalbek from BahrÃÂm ShÃÂh. Failing that, he attempted to take the town by siege until ordered to desist by his nephew, al-NÃÂá¹£ir DÃÂÃ¾à «d. This caused a rift between the two and al-ÿAzëz joined al-KÃÂmil with the army of Banyas at Nablus in August 1228, when the sultan was preparing to dispossess al-NÃÂá¹£ir. At this time, al-KÃÂmil may have recognized al-ÿAzëz as autonomous in Banyas. Thereafter, he would cease to owe his position to the ruler of Damascus. Already by 1226, al-ÿAzëz had begun to call himself al-sultan in his inscriptions.
In the negotiations that followed, al-ÿAzëz ÿUthmÃÂn acquired Baalbek. Following the siege of Damascus in June 1229, however, his brother al-Ashraf refused to hand it over. This betrayal did not cause a permanent rift. In 1230, al-ÿAzëz joined al-Ashraf's army that defeated the Khwarazmshah JalÃÂl al-Dën at the battle of Yasi-chimen on 9 August. He was also present at the brief siege of Amida in 1232.
Al-ÿAzëz ÿUthmÃÂn died not long after this last campaign, on 10 Ramaá¸ÂÃÂn 630 AH (20 June 1233). He was succeeded in Banyas by his eldest son, al-áºÂÃÂhir GhÃÂzë, who soon died and was succeeded by a younger son, al-á¹¢aÿëd Ḥasan.
