An-Nasir Ahmad, Sultan of Egypt (b. 1316)
An-Nasir Shihab ad-Din Ahmad ibn Muhammad ibn Qalawun, better known as an-Nasir Ahmad, (1316 – 16 July 1344) was the Bahri Mamluk sultan of Egypt, ruling from January to June 1342. A son of Sultan an-Nasir Muhammad, he became embroiled in the volatile succession process following his father's death in 1341. An-Nasir Ahmad lived much of his life in the desert fortress of al-Karak in Transjordan and was reluctant to assume the sultanate in Cairo, preferring al-Karak, where he was closely allied with the inhabitants of the city and the Bedouin tribes in its vicinity. His Syrian partisans, emirs Tashtamur and Qutlubugha al-Fakhri, successfully maneuvered to bring Syria under an-Nasir Ahmad's official control, while sympathetic emirs in Egypt were able to oust the Mamluk strongman Emir Qawsun and his puppet sultan, the five-year-old half-brother of an-Nasir Ahmad, al-Ashraf Kujuk. An-Nasir Ahmad eventually assumed the sultanate after frequently delaying his departure to Egypt.

An-Nasir Ahmad was known to be a seclusive sultan, surrounding himself with his coterie of supporters from al-Karak, rarely making direct contact with the Mamluk emirs of Egypt and avoiding the public view. Two months into his reign, he relocated to al-Karak with substantial sums from the treasury and several horses and senior administrative officials. He ruled from the desert fortress, leaving a deputy, Emir Aqsunqur al-Salari, to oversee affairs in Egypt on his behalf. His unorthodox rule, alleged frivolity, and his execution of loyal partisans, namely Tashtamur and Qutlubugha, led to an-Nasir Ahmad being deposed from the sultanate by his half-brother, as-Salih Isma'il. He remained in the fortress of al-Karak, which the Mamluks besieged at least seven times, until being captured in July 1344. He was killed later that month on the orders of as-Salih Isma'il.
