An-Nasir Hasan

An-Nasir Badr ad-Din Hasan ibn Muhammad ibn Qalawun (1334/35–17 March 1361), better known as an-Nasir Hasan, was the Mamluk sultan of Egypt, and the seventh son of an-Nasir Muhammad to hold office, reigning twice in 1347–1351 and 1354–1361. During his first reign, which he began at age 12, senior Mamluk emirs formerly belonging to an-Nasir Muhammad, dominated his administration, while an-Nasir Hasan played a ceremonial role. He was toppled in 1351 when he attempted to assert executive authority to the chagrin of the senior emirs. He was reinstated three years later during a coup against his brother Sultan as-Salih Salih by emirs Shaykhu and Sirghitmish.

During his second reign, an-Nasir Hasan maneuvered against the leading emirs, gradually purging them and their supporters from the administration through imprisonment, forced exile and execution. He replaced many mamluks with awlad al-nas (descendants of mamluks), who he found to be more reliable, competent and amiable with the public. An-Nasir Hasan was killed by one of his own mamluks, Yalbugha al-Umari, who headed a faction opposed to an-Nasir Hasan's elevation of the awlad al-nas. Throughout his second reign, an-Nasir Hasan commenced the Sultan Hasan Mosque-Madrasa complex in Cairo, as well as other architectural works, namely religious structures, in Cairo, Jerusalem, Gaza and Damascus.
