Al-Malik an-Nasir Nasir ad-Din Muhammad ibn Qalawun, commonly known as an-Nasir Muhammad, or by his kunya: Abu al-Ma'ali or as Ibn Qalawun (1285–1341) was the ninth Mamluk sultan of the Bahri dynasty who ruled Egypt between 1293–1294, 1299–1309, and 1310 until his death in 1341. During his first reign he was dominated by Kitbugha and al-Shuja‘i, while during his second reign he was dominated by Baibars and Salar. Not wanting to be dominated or deprived of his full rights as a sultan by his third reign, an-Nasir executed Baibars and accepted the resignation of Salar as vice Sultan.
