Nāṣir ad-Dīn Maḥmūd (Persian: ناصر الدين محمود) was the eldest son of the Delhi Sultan Shamsuddin Iltutmish and his chief consort Turkan Khatun,^[1] (as the court historian Minhaj-i Siraj Juzjani clearly mentioned in the Tabaqat-i Nasiri, the only contemporary source of history of that time), the daughter of Qutb ud-Din Aibak. He was, in all probabilities, the full brother of Razia Sultana.^[2] He was the governor of Awadh and later served as the governor of Bengal (Preceded by Iwaz Khalji) until his death in 1229. Then in 1230 the son of Ali Sher Khalji, Balka Khalji declared himself as independent king of Bengal. Thus in 1231 Iltutmish marched against him and defeated him and made Alauddin Jani as the next governor of Bengal.
