Prince Karim, 88, was given the title of “His Highness” by Queen Elizabeth in July 1957, two weeks after his grandfather, the Aga Khan III, unexpectedly made him heir to the family’s 1,300-year dynasty as leader of the Ismaili Muslim sect.

As leader of a branch of Shiite Islam, the Aga Khan mixed business projects and humanitarian initiatives as he built a personal fortune.
