Aga Khan (Persian: آقاخان; also transliterated as Aqa Khan and Agha Khan) is a name used by the Imam of the Nizari Ismailis. The current user of the name is the 49th Imam (1957–present), Prince Shah Karim Al Husseini Aga Khan IV (b. 1936).
The title is made up of the titles agha and khan. The Turkish "agha" is "aqa" (Āqā) in Persian. The word "agha" comes from the Old Turkic and Mongolian "aqa", meaning "elder brother", and "khan" means king, ruler in Turkic and Mongolian languages.
According to Farhad Daftary, 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. However, Daftary 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.
During the latter stages of the First Anglo-Afghan War (1841-1842), Hasan Ali Shah and his cavalry officers provided assistance to General Nott in Kandahar Province and to General England in his advance from Sindh to join Nott. 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 salute; When Hasan Ali Shah, the first Aga Khan, came to Sindh, which is now in Pakistan, from Afghanistan, he and his army were welcomed by Mir Nasir Khan of Baluchistan. In 1866, the Aga Khan won a court victory in the High Court of Bombay in what popularly became known as the Aga Khan Case, securing his recognition by the British government as the head of the Khoja community.
