Nasir-ud-Din Mahmud (AH 644–664; 1246–1266 AD)

 In 1246, Nasir-ud-Din Mahmud became the eighth sultan of the Mamluk Dynasty. He was the son of Nasiruddin Mahmud (died 1229), who was the eldest son of Shams ud din Iltutmish.

The young king possessed the virtues of continence, frugality and practical piety, rare during that time. He was a pious, God-fearing, compassionate ruler, who patronized the learned and sympathized with the poor and the distressed. Unlike many of his predecessors and successors, Mahmud strictly followed monogamy. He spent most of his time writing down verses of the Quran. He sold the handwritten copies and used the money for his personal expenses. Surprising enough, he had no servants to carry out his personal tasks. His wife had to cook the food for the family.

It is said that Nasir-ud-Din was the nominal king, but the reigns of the power were in the strong hands of his father-in-law and Deputy Sultan or Naib, Ghiyas ud din Balban, .

After Mahmud's death in 1266, Balban (1266–87) rose to power as Mahmud had no children to be his heir. It was alleged that Balban poisoned Mahmud.
