Aga Khan IV (1936–2025), spiritual leader, magnate, and philanthropist

by Eric San Juan

The Aga Khan IV was the spiritual leader of the Isma’ili branch of Shia Islam, a billionaire philanthropist who helped build homes, hospitals and schools throughout the world. 

The Aga Khan IV’s legacy 

He was born Prince Karim Al-Husseini, but to millions of his Isma’ili followers, he was the Aga Khan IV, a direct descendant of the Prophet Muhammad and a spiritual leader who was both a fabulously wealthy billionaire and a noted philanthropist. 

Al-Husseini became the Aga Khan IV in 1957 at age 20 after the passing of his grandfather, the Aga Khan III, superseding both his father and uncle. Born in Switzerland, he inherited massive wealth and spent his youth studying at elite boarding schools and universities, including Harvard. He was even a competitive downhill skier in his youth, racing for Great Britain in the 1962 FIS Alpine World Ski Championships and Iran in the 1964 Winter Olympics. 

As the Aga Khan IV, he devoted billions towards helping Nizari Ismailis, especially those in developing nations. Through his Aga Khan Development Network, an umbrella organization for an array of different agencies – some for profit, some not – he directed funds towards health education and services, the construction of hospitals, economic development, especially in Africa and Asia; building homes and schools, and more. 

He also enjoyed a lavish lifestyle, with a particular interest in horse racing. He had a private island in the Bahamas, a private jet, a 164-foot superyacht, the Alamshar, and owned hundreds of valuable racehorses and horse breeding/stud farms in France and Ireland. 

The Aga Khan IV received dozens of honors over the course of his life, including the Andrew Carnegie Medal of Philanthropy, Philanthropic Entrepreneur of the Year by Le Nouvel Économiste in France, and countless others from an array of nations. 

Notable quote 

“(The goal) is to improve the quality of life and that indeed involves reducing poverty, but it also provides people with the means to improve their quality of life. That is the goal.” — 2019 interview with the Aga Khan Development Network 

Tributes to the Aga Khan IV 

As an Ismaili Muslim, I am devastated by the news of the passing of His Highness the Aga Khan. As a Canadian and a citizen of the world, I also mourn the loss of one of the greatest servants of humanity but I am also deeply grateful for his extraordinary life of service. /1

For those who don’t know, the Aga Khan Foundation is one of the world’s biggest and most respected philanthropic institutions in the world. It builds hospitals and schools, and supports free press initiatives, to name just a fraction of what it does.It affects millions of people in Asia and Africa.

Aga Khan was first of all a very successful businessman. I had the pleasure to talk to him in person during a night flight from India to Europe for at least an hour. I very seldom met such a friendly, warm hearted personality. What a loss for mankind!

On this “brisk” winter day in #Edmonton, thinking about the late Aga Khan’s generous gift to the University of Alberta Botanic Garden. The world’s Ismaili community is mourning. But know that the Aga Khan’s memory will be a blessing here for decades. #yeg #UniversityofAlberta #ualberta #AgaKhan
