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.

Prince Karim Aga Khan IV, the 49th hereditary Imam of the Ismaili Muslims, was laid to rest in Aswan, Egypt, on Sunday during a private ceremony. His death, which was announced on February 4, 2025, at the age of 88, has left the global Ismaili Muslim community in mourning. He was laid to rest in Aswan in accordance with his last wish.

Canadian Prime Minister Justin Trudeau and Spain’s King Emeritus Juan Carlos were among the dignitaries who attended Saturday’s private ceremony for His Highness Prince Karim Al-Hussaini at the Ismaili community center. Portugal’s President Marcelo Rebelo de Sousa and the mayor of Lisbon were also among the mourners.

The interment was attended by Prince Rahim Aga Khan V, the 50th Ismaili Imam, family members, and leaders of the global Ismaili community.

Aga Khan IV, leader of Ismaili Muslims, was buried in Aswan, Egypt, following a private ceremony in Lisbon. His successor, Aga Khan V, was named by will.

Prince Karim al-Hussaini Aga Khan IV, the 49th Imam of the Shia Ismaili Muslims, will be laid to rest today in Aswan, Egypt in a private burial ceremony.

Charles is continuing a long-standing tradition and following in the footsteps of his mother Queen Elizabeth II.
