The Aga Khan IV, the revered imam of the world’s Ismaili Muslims, has passed away at the age of 88, confirmed by his philanthropic organization, the Aga Khan Development Network. His death occurred on February 4, 2025, in Lisbon, Portugal, where he died peacefully surrounded by family.
Born on December 13, 1936, Prince Karim Al-Hussaini became the 49th hereditary imam of the Shia Ismaili Muslims at just 20 years old. His grandfather, the Aga Khan III, named him as his successor, bypassing his own son due to the belief expressed in his will which noted the necessity for “a young man who has been brought up and developed during recent years” to lead the increasingly complex world.
Throughout his extraordinary life, the Aga Khan skillfully combined moral leadership and philanthropy with business acumen, managing extensive enterprises reputedly valued between $1 billion and $13 billion. He founded the Aga Khan Development Network (AKDN) in 1967, which has since created countless hospitals, schools, and housing projects across developing countries, working primarily to bring healthcare, education, and economic opportunities to some of the world's poorest populations.
“We have no notion of the accumulation of wealth being evil,” the Aga Khan once said, adding how the Islamic ethic demands the privileged to contribute positively to society. His commitment to this ethic manifested as he personally oversaw projects dedicated to enhancing quality of life for his followers, who are believed to be direct descendants of the Prophet Muhammad through Ali and Fatima, their first imam.
Canadian Prime Minister Justin Trudeau, speaking at a Lunar New Year reception shortly after the announcement of the Aga Khan's death, described him as “an extraordinarily compassionate global leader.” He remarked on the contributions the Aga Khan made not only to the Ismaili community but also to Canadian society, noting the bond formed when Canada welcomed Ismaili refugees during the early 1970s, after dictatorial upheaval forced them to flee Uganda.
His work included significant contributions to Canada, where he established the Global Centre for Pluralism and the Aga Khan Museum, which showcases Islamic art and culture. Recognized for his efforts, the Aga Khan was granted honorary Canadian citizenship in 2009. Trudeau expressed his deep sadness, sharing, “He will be deeply missed by people around the world, particularly by the Ismaili community.”
Although his passing marked the loss of significant leadership for Ismailis, who are dispersed across 15 million adherents in over 35 countries, it also reignited conversations around his successful endeavors and the legacy he leaves behind. His contribution to improved health and educational opportunities is widely regarded and complemented by support for pluralism and interfaith dialogues.
The Aga Khan's leadership style combined respect for tradition with modern pragmatism. His influence extended globally, where he navigated development, culture, and diplomacy as he established institutions and initiatives aimed at fostering inclusivity and community empowerment.
His philanthropic work through AKDN saw billions of dollars funneled toward alleviating poverty, with highlights such as the construction of the University of Central Asia and efforts to develop infrastructure and healthcare systems. He fundamentally believed these were acts of faith grounded in the need to uplift those less fortunate.
Tragically, his death is significant not only for the Shia Ismaili community but also for the broader global community which benefited from his humanitarian initiatives. A statement from the Aga Khan Development Network expressed condolences to his family and the Ismaili population worldwide, promising details about his designated successor will be released soon.
The Aga Khan IV was also known for his ventures outside of philanthropy, particularly his interest in thoroughbred horse racing. He owned numerous racehorses and was regarded as one of the world's leading figures in the sport, winning prestigious races with champions such as Shergar, who became famously kidnapped and never recovered.
He lived most of his life abroad, including significant periods based in France and Portugal, but his connections to Canada remained deep. Trudeau referred to the Aga Khan as “a friend of my father's and my own,” highlighting the personal bonds formed over decades.
This multifaceted man of faith and industry leaves behind three sons, a daughter, and several grandchildren, marking the end of a historic era. He will be buried in Lisbon, with arrangements forthcoming as his family and community prepare to mourn.
For Ismailis worldwide, this loss is felt deeply, as they navigate together through grief, reflecting on the rich legacy left behind by a leader who impacted their lives immeasurably.
