Prince Shah Karim Al Hussaini Aga Khan (IV) is a Swiss-born British business tycoon, as well as the 49th and current Imam of ‘Nizari Ismailism’. Educated in Switzerland and at Harvard University, he was chosen as the successor to the imamate of the Nizārī Ismāʿīlī sect by his grandfather, the Aga Khan III, whom he succeeded in 1957.

Through organizations such as the ‘Aga Khan Foundation’, the imamate funded aid agencies offering educational, health, and housing services in South Asia and East Africa.

One of the world's ten richest royals, ‘His Royal Highness’ has been on the throne for more than 50 years.
