Nasir-ud-din Mahmud of Slave Dynasty

Nasir-ud-din Mahmud, a grandson of Iltutmish, was one of the sultans of the Slave Dynasty. He was placed on the throne of Delhi Sultanate by the nobles in 1246 after the incompetent reigns of his predecessors Muiz-ud-din Bahram (1240-42) and Ala-ud-din Masud Shah (1242-46).

Nasir-ud-din Mahmud was only sixteen when he ascended the throne. During his twenty year rule, he remained content in surrendering the power of the state to Balban, one of his Turkish minister.

In 1249, Nasir-ud-din Mahmud married the daughter of Balban. This increased the power of Balban who was made his deputy (naib-i-mamalakat) and given the title of Ulugh Khan (premier ‘Khan’).

Balban, de facto ruler of Delhi, managed the affairs of the sate competently. Internal rebellions were suppressed. Mongol invasions were successfully repulsed. This aroused the jealousy of the other nobles. This led to his exile from 1253 to 1255. But as they created a mess of the administration, he was once again recalled by the Sultan. 
 

Nothing can be said with certainty about the last years of Nasir-ud-din Mahmud who died on in 1266. If the accounts of the fourteenth century historian Isami and African traveler Ibn Batutah are to be believed, the Salve Sultan was murdered by Balban. Since Nasir-ud-din Mahmud had no male heir behind him, Balban ascended the throne of Delhi Sultanate. According to some authorities, the Sultan had nominated him as his successor before his death.

 

An intensely religious-minded person, Nasir-ud-din spent his leisure times in copying the Quran. Himself an expert calligraphist, he patronized Minhaj-us-Siraj who wrote Tabaqat-i-Nasiri and dedicated it to the Sultan.
