It was with Zulfiqar Khan's aid and intrigues that Jahandar Shah after the death of his father Bahadur Shah I, overcame all his brothers and ascended the throne of Delhi when he was appointed as Vizir-e-Azam or Prime Minister. Zulfiqar Khan was the first prime minister of the Mughal Empire to have more power in the government of the empire than any Emperor since the early years of the reign of Akbar.John F. Richards, The New Cambridge History of India: The Mughal Empire (New York: Cambridge University Press, 1993), p. 262
