Al-Mansur Nasir al-Din Muhammad (Arabic: المنصور ناصر الدين محمد بن العزيز; 1189 – after 1216) was the third Ayyubid Sultan of Egypt, reigning in 1198–1200.
The grandson of the Ayyubid dynasty's founder, Saladin, al-Mansur succeeded his father al-Aziz Uthman on the latter's death in 1198, at the age of twelve.
[1] A struggle subsequently ensued between different military factions as to who should serve as his atabeg al-asakir or commander in chief, and effective regent.
[2] In the struggle which followed al-Afdal had the initial advantage of being based in Egypt, while al-Adil was in Syria.
War broke out between them and al-Afdal attacked Damascus, but he soon lost the advantage and in February 1200 (Rabi' II 596), al-Adil entered Cairo.
