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.

The Aga Khan’s burial came five days after he passed away on February 4 in Lisbon, Portugal, at the age of 88.

Rahim Al-Hussaini was named Wednesday as the new Aga Khan, spiritual leader of the world’s millions of Ismaili Muslims, following the death of his father.

His Highness the Aga Khan, the 49th hereditary spiritual leader of the Shia Ismaili Muslims and the founder of Aga Khan Development Network, is dead. Prince Karim Al-Hussaini Aga Khan IV died in Lisbon, Portugal, on Tuesday, February 4, surrounded by his family.

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.

Hussaini, will oversee the plans to open the million-dollar Ismaili Muslim community hub after his father's recent passing.
