His Highness Prince Karim Al-Hussaini, known as Aga Khan IV, the 49th hereditary Imam of the Shia Ismaili Muslims, passed away on February 4, 2025, in Lisbon, Portugal, at the age of 88. He was surrounded by his family at the time of his death. The Aga Khan was a prominent spiritual leader and philanthropist, dedicating his life to the betterment of Ismaili Muslims and communities worldwide.
Early Life and Education
Born on December 13, 1936, in Geneva, Switzerland, Prince Karim was the son of Prince Aly Khan and Princess Taj-ud-dawlah. He spent part of his childhood in Nairobi, Kenya, before pursuing higher education at Harvard University, where he studied Islamic history. In 1957, at the age of 20, while still an undergraduate, he succeeded his grandfather, Aga Khan III, as the Imam of the Ismaili community. His grandfather chose him over his father, emphasizing the need for a leader who had been “brought up in the midst of the new age.”
Leadership and Philanthropy
As the spiritual leader of approximately 12 to 15 million Ismaili Muslims across more than 25 countries, Aga Khan IV emphasized the importance of improving quality of life through education, healthcare, and economic development. He founded the Aga Khan Development Network (AKDN), which operates in over 30 countries with an annual budget of about $1 billion dedicated to non-profit development activities. The AKDN focuses on various sectors, including health, education, culture, and rural development, aiming to enhance living conditions and opportunities in developing regions.
Personal Life and Interests
Beyond his religious and philanthropic endeavors, the Aga Khan was known for his passion for horse racing and breeding. He owned several successful racehorses, including the legendary Shergar, who won the Epsom Derby in 1981. His interest in architecture led him to establish the Aga Khan Award for Architecture, promoting excellence in design and the preservation of Islamic architectural heritage.
In his personal life, the Aga Khan married twice. His first marriage was to British model Sarah Frances Croker Poole in 1969, with whom he had three children: Princess Zahra, Prince Rahim, and Prince Hussain. The couple divorced in 1995. In 1998, he married Gabriele Renate Thyssen, who became known as Begum Inaara Aga Khan. They had one son, Prince Aly Muhammad, before divorcing in 2014.
Global Recognition and Tributes
The Aga Khan’s efforts in bridging cultural divides and promoting development earned him international acclaim. He was granted the title of “His Highness” by Queen Elizabeth II in 1957 and received numerous honors throughout his life. Following his passing, tributes poured in from around the world. Canadian Prime Minister Justin Trudeau described him as “an extraordinarily compassionate global leader” and a “very good friend.” The United Nations and various global leaders also expressed their condolences, highlighting his significant contributions to humanitarian causes.
Succession
According to Ismaili tradition, the Aga Khan’s successor is designated through a written will. The name of his successor will be announced after the will is read in the presence of his family and senior community leaders in Lisbon. It is anticipated that his eldest son, Prince Rahim Aga Khan, will assume the role of the 50th Imam of the Shia Ismaili Muslims, continuing his father’s legacy of leadership and service.
Legacy
Aga Khan IV leaves behind a profound legacy of spiritual guidance and humanitarian work. His dedication to improving the lives of millions through the Aga Khan Development Network has had a lasting impact on communities worldwide. His vision of a harmonious world, where faith and development coexist, continues to inspire and guide future generations.
