Nasiruddin Mahmud was the grandson of Iltutmish and occupied the throne of the Delhi Sultanate for twenty years. His reign represents a distinct phase in the Mamluk (Slave) Dynasty characterized by the absolute consolidation of power in the hands of the nobility, specifically Ghiyas-ud-din Balban. Unlike the assertive monarchs before him, Nasiruddin Mahmud is historically depicted as a figurehead whose primary interest lay in religious piety and simple living, which allowed the factional politics of the Turkish slave-officers to reach their zenith.
The Dominance of Ghiyas-ud-din Balban
The most critical political development during this period was the rise of Balban, who served as the Naib-i-Mamlakat (Deputy of the Kingdom). Nasiruddin Mahmud effectively delegated all administrative and military authority to Balban, who used this tenure to eliminate his rivals within the Chahalgani (The Corps of Forty).
- Balban successfully sidelined the older Turkish nobility who had held significant influence since the time of Iltutmish.
- By acting as the de facto ruler, Balban stabilized the Sultanate against the recurring threats of the Mongol invasions in the northwest and internal rebellions from Rajput chieftains.
- The Sultan maintained a reputation for austerity, reportedly earning his living by copying the Quran and sewing caps, which contrasted sharply with the extravagant military campaigns led by Balban on his behalf.
Administrative and Military Developments
Despite the Sultan’s personal disinterest in statecraft, the administration during this era focused on suppressing centrifugal forces that had emerged following the death of Iltutmish.
- The Iqtadari system was strictly monitored to ensure that provincial governors remained subservient to the central authority in Delhi.
- Military campaigns were conducted against the Mewatis, the rebellious elements in the Doab region, and the independent Rajput rulers of Ranthambore and Gwalior to ensure the security of the core territories.
- The Sultanate’s frontier policy was defensive, focusing on fortifying the western borders against the Mongol threat, which became a recurring challenge during the middle of the 13th century.

Challenges and Political Factionalism
The reign was marked by intense competition between two primary factions within the royal court. The initial phase saw the influence of the Turkish nobility represented by Balban, which was temporarily challenged by a group of Indian Muslim converts and other non-Turkish elements led by Imad-ud-din Raihan.
- Imad-ud-din Raihan briefly succeeded in getting Balban exiled from the court by convincing the Sultan that Balban was becoming too powerful.
- Balban’s subsequent return and the eventual purge of his rivals cemented the idea that only a strong, centralized monarchy, rather than a collaborative nobility, could ensure the survival of the Delhi Sultanate.
- This period served as a training ground for Balban, who eventually succeeded Nasiruddin Mahmud upon the latter’s death, transitioning the dynasty from the era of the ‘Forty’ to the era of absolute kingship.
