Born Aziz-ud-Din, the second son of Jahandar Shah, was raised to the throne by Imad-ul-Mulk after he deposed Ahmad Shah Bahadur in 1754. On ascending the throne, he took the title of Alamgir and tried to follow the approach of Aurangzeb (Alamgir I). At the time of his accession to throne he was an old man of 55 years. He had no experience of administration and warfare as he had spent most of his life in jail. He was a weak ruler, with all powers vested in the hand of his vizier, Ghazi-ud-Din Imad-ul-Mulk.
