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. He was the grandson of the Ayyubid dynasty's founder, the famous Saladin.
Al-Mansur succeeded his father al-Aziz Uthman on the latter's death in 1198, at the age of twelve. 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.
He only lasted a couple years then was deposed in February of the year 1200 AD. After his deposition al-Mansur was exiled to Aleppo in Syria. There, he lived in the court of his uncle, Emir az-Zahir Ghazi, who, in 1216, placed him in the line of succession for the emirate should his own sons predecease him. Nothing further is known of al-Mansur.
A short reign makes a tough coin. There are only 13 to 20 of these I can find on ACSearch going back to 2001. This is the only one graded by NGC as of December, 2022.
