9. Prince Shah Karim Al Hussaini- Aga Khan IV – (Net worth: $800 Million)
Prince Shah Karim Al Hussaini, Aga Khan IV, born 13 December 1936, is the 49th and current Imam of Nizari Ismailism, a denomination of Isma’ilism within Shia Islam consisting of an estimated 25 million adherents (about 20% of the world’s Shia Muslim population).The Aga Khan is a British, business magnate, racehorse owner and breeder. He has held this position of Imam, under the title of Aga Khan IV, since 11 July 1957, when, at the age of 20, he succeeded his grandfather, Sir Sultan Muhammad Shah Aga Khan III. It is believed that the Aga Khan is a direct lineal descendant of the Islamic prophet Muhammad through Muhammad’s cousin and son-in-law, Ali, considered the first Imam in Shia Islam, and Ali’s wife Fatima az-Zahra, Muhammad’s daughter from his first marriage. In 1986 the Aga Khan ordained the current version of the Ismailia Constitution – an ecclesiastical decree affirming to Nizari Ismailis his “sole right to interpret the Qur’an and provide authoritative guidance matters of faith” and formalising his sole discretion, power and authority for the governance of Nizari Ismaili jamats (places of worship) and institutions.
Forbes describes the Aga Khan as one of the world’s ten richest royals with an estimated net worth of US$800 million (2010). Additionally he is unique among the richest royals as he does not rule over a geographic territory. Among the goals the Aga Khan has said he works toward are the elimination of global poverty; the promotion and implementation of secular pluralism;the advancement of the status of women; and the honouring of Islamic art and architecture.
