Aga Khan (Persian: آقاخان; also transliterated as Aqa Khan and Agha Khan1) is a name used by the Imam of the Nizari Ismailis since 1818. The current user of the name is Shah Karim who claim to be the 49th Imam (1957–present), Prince Shah Karim Al Husseini Aga Khan IV (b. 1936).
According to Farhad Daftary,2 Aga Khan is an honorific title bestowed on Hasan Ali Shah (1800–1881), the 46th Imam of Nizari Ismailis (1817–1881), by Persian king Fath-Ali Shah Qajar.3 However, what Daftary says contradicts what the Aga Khan III noted in a famous legal proceeding in India - that Aga Khan is not a title, but instead a sort of alias or "pet name" that was given to the Aga Khan I when he was a young man.4
During the latter stages of the First Anglo-Afghan War (in 1841 and 1842), Hasan Ali Shah and his cavalry officers provided assistance to General Nott in Kandahar Province and also to General England in his advance from Sindh to join Nott.citation needed He was awarded the status of "Prince" by the British government's representatives in India and became the only religious or community leader in British India granted a personal gun salutecitation needed; When Hassan Ali Shah, the first Aga Khan, came to Sindh from Afghanistan, he and his army were welcomed by Mir Nasir Khan of Baluchistan.citation needed In 1887, the Secretary of State for India acting through the Viceroy of India, formally recognized the title Aga Khan.citation needed
