Aga Khan IV Passes Away at 88

At just 20 years old, he assumed leadership of a Shia Muslim line and, through his entrepreneurial ventures, rose to become one of the globe’s wealthiest hereditary leaders.

Aga Khan IV, the spiritual head of the Ismaili Muslims, combined business acumen with philanthropic efforts to amass substantial wealth. He died on Tuesday in Lisbon, aged 88.

His passing was confirmed by the Aga Khan Development Network via a post on X, without disclosing the cause.

Known for his sophisticated and worldly demeanor yet often shunning the media, Prince Karim Al-Hussaini—Aga Khan IV—argued that growing his wealth did not conflict with his charitable missions. He stated it was his responsibility to uplift the quality of life for the 15 million-strong Ismaili Muslim community spread across 35 nations.

As a faith leader, he believed engagement in daily affairs was crucial. He once articulated that withdrawing from worldly matters was against the essence of Islam's teachings, as an imam's role included safeguarding and enhancing the community’s welfare.

Among his initiatives was the upscale development of Sardinia’s Costa Smeralda, breeding racehorses, and launching health projects in developing nations.

Despite owning private jets, a luxury yacht, a Caribbean island, and multiple residences, including a vast estate near Paris, he disputed portrayals of his lifestyle as extravagant. This estate served as both a development hub and equestrian center.

In 2006, he emphasized an imam’s dual duty of faith interpretation and actively striving to enhance community security and life quality.

Although he did not inherit a traditional realm, his wealth was estimated between $1 to $13 billion, bolstered by investments and a religious contribution known as zakat from his followers.

The title of Aga Khan, a fusion term suggesting a commanding chief, was passed to him from his grandfather, bypassing other relatives. As the 49th imam, his leadership of a Shia lineage traced to the Prophet Muhammad carried significant duties.
