Jakmak's rule was mild compared with that of Bursbai, and we hear less of extraordinary taxes, extortions, executions, and violence of the Mamluks. Although he was beloved by the people and priests on account of his piety, he could not secure the succession of his son Osman, in favour of whom he abdicated fourteen days before his death (February, 1453). Osman remained only a month and a half on the throne; he made himself odious to the emirs who did not belong to his Mamluks. The Mamluks of his predecessors conspired against him, and at their head stood his own Atabeg, the Emir Inal, a former Mamluk of Berkuk. Osman was warned, but he only mocked those who recommended him to watchfulness, since he believed his position to be unassailable. He had forgotten that his father was a usurper, who, although himself a perjurer, hoped to bind others by means of oaths. His eyes were not opened until he had lost all means of defence. He managed to hold out for seven days, after which the citadel was captured by the rebels, and he was forced to abdicate on the 19th of March. Inal became, even more than his predecessors had been, a slave to those Mamluks to whom he owed his kingdom. They committed the greatest atrocities and threatened the sultan himself when he tried to hold them in check. They plundered corpses on their way to the grave, and attacked the mosques during the hours of service in order to rob the pilgrims. They were so hated and feared that, when many of them were carried off by the plague, their deaths were recorded by a contemporary historian as a benefit to all classes of society.
