Nasiruddin Mahmud

Nāṣir ad-Dīn Maḥmūd was the eldest son of the Delhi Sultan Shamsuddin Iltutmish and his chief consort Turkan Khatun,, the daughter of Qutb ud-Din Aibak. He was, in all probabilities, the full brother of Razia Sultan. He was the governor of Awadh and later served as the governor of Bengal 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.
