Iltutmish's Tomb close to Qutub Minar, Delhi
In A.D. 1236 Iltumish died, and buried with the Qutb complex in Mehrauli.Iltutmish's eldest son, Nasir-ud-din Mahmud, had died in 1229 while governing Bengal as his father's deputy. The surviving sons of the Sultan were incapable of the task of administration. In A.D. 1236 Iltutmish, on his death-bed, nominated his daughter Raziya as his heiress. But the nobles of the court were too proud to bow their heads before a woman, and disregarding the deceased Sultan's wishes, raised to the throne his eldest surviving son, Rukn-ud-din Firuz.The death of Iltutmish was followed by years of political instability at Delhi. During this period, four descendants of Iltutmish were put on the throne and murdered. Order was re-established only after Balban became the Naib or Deputy Sultan and later on Sultan in A.D. 1265.
