In 1210, Qutb al-Din Aibak died unexpectedly in Lahore during a sport game, without having named a successor. To prevent instability in the kingdom, the Turkic nobles (maliks and umara) in Lahore appointed Aram Shah as his successor at Lahore.[3] However, the Turkic nobles in different parts of the Sultanate opposed his ascension, and some of them - such as the Khalji nobles of Bengal - rebelled against him. According to the 16th century historian Firishta, the kingdom also suffered an invasion from the neighbouring ruler Nasir ad-Din Qabacha of Multan.
A group of nobles, led by the military justiciar (Amir-i Dad) Ali-yi Ismail, invited Iltutmish to occupy the throne. Iltutmish, a former slave of Aibak and the governor of Badaun, had a distinguished record of service and was called a son by Aibak, because of which the nobles considered him as a good candidate for the throne. Iltutmish marched to Delhi, where he seized the power, and later defeated Aram Shah's forces at Bagh-i Jud. According to the Tabaqat-i Nasiri, Aram Shah was "martyred": it is not clear if he was killed on the battlefield, or put to death as a prisoner of war. Two of his important officers - Aqsanqar and Farrukh Shah - were killed on the battlefield. Iltutmish subsequently consolidated his power and began ruling from Delhi.
