If you’ve ever found yourself scrolling through news about the world's most influential families, you’ve likely hit on the name "Aga Khan." It sounds grand, doesn't it? It is. But behind the glossy photos of horse races in Chantilly or the high-level diplomatic meetings in Lisbon, there is a family tree that stretches back so far it makes most European royalty look like newcomers. We’re talking about a lineage that claims direct descent from the Prophet Muhammad.
Honestly, the aga khan family tree isn’t just a list of names. It’s a map of Islamic history, a story of empires lost, and a masterclass in how a spiritual dynasty survives the modern world.
The Roots: From Seventh-Century Arabia to the Fatimids
To understand where the current Aga Khan comes from, you have to go back—way back. The family identifies as the hereditary Imams of the Shia Ismaili Muslims. This means they trace their bloodline through the Prophet’s daughter, Fatima, and his son-in-law, Ali.
For the Ismailis, this isn't just a historical footnote. It's the whole point.
The lineage isn't just about survival; it’s about power. Around the 10th century, this family tree sprouted a massive branch: the Fatimid Caliphate. These guys weren't just spiritual leaders; they were emperors. They founded Cairo. They built Al-Azhar, one of the oldest universities in the world. Imagine being able to look at your family tree and see the people who literally built the heart of Egypt.
Eventually, the empire fell. The family went into a "period of concealment" for a while, moving through Persia (modern-day Iran). This is where the story gets kinda wild. They weren't always called "Aga Khan." That's actually a relatively new title.
Where the "Aga Khan" Title Actually Started
Most people assume the title is ancient. It’s not. It was actually given to the 46th Imam, Hasan Ali Shah, in the early 1800s by the Shah of Persia. "Aga" and "Khan" both basically mean "Lord" or "Commander" in Turkic and Persian dialects.

Hasan Ali Shah became Aga Khan I. He didn't have the easiest time in Persia, though. After some political drama and a failed revolt, he eventually moved to India in the 1840s. This move changed everything. It brought the family under the orbit of the British Empire, which is why the later Aga Khans ended up with such deep ties to the West.
The Man Who Modernized the Brand: Aga Khan III
If there’s one person in the aga khan family tree who defined the modern era, it’s Sir Sultan Mahomed Shah, or Aga Khan III. He was the grandfather of the late Karim Aga Khan (Aga Khan IV).
He was a powerhouse.
A founding father of the All-India Muslim League.
President of the League of Nations.
He was also the guy who famously got weighed in diamonds, gold, and platinum by his followers during his various jubilees.
But he was also deeply pragmatic. He saw the world changing and pushed his community to modernize, especially focusing on education for women. He lived through two World Wars and realized the next Imam needed to be someone who understood the future, not just the past.
The Shocking Succession of 1957
Usually, the title goes from father to son. That's the standard play. But in 1957, when Aga Khan III passed away, his will contained a massive curveball. He skipped over his son, the famous Prince Aly Khan (who was known as a bit of a socialite and was famously married to Hollywood star Rita Hayworth), and named his 20-year-old grandson, Karim, as the next Imam.
Imagine being a student at Harvard and suddenly finding out you’re the spiritual leader of 15 million people.

That was Aga Khan IV. He spent the next 67 years building what we now know as the Aga Khan Development Network (AKDN). He turned the role into a sort of "statesman without a state." He didn't rule a country, but he was treated like a head of state by almost every government on earth.
The New Era: Aga Khan V
History doesn't stand still. On February 4, 2025, Prince Karim Aga Khan IV passed away in Lisbon at the age of 88. His death marked the end of an era that lasted over six decades.
His successor? Prince Rahim Aga Khan, now known as Aga Khan V.
Prince Rahim is the 50th hereditary Imam. He’s half-British (his mother is the former model Sarah Croker-Poole, known as Princess Salimah) and has spent decades preparing for this. He’s already been leading the charge on the family’s environmental and climate initiatives.
A Quick Look at the Modern Family Structure
While the lineage is a straight line of succession, the family itself is quite large and spread across the globe.
- Prince Rahim (Aga Khan V): The current Imam, based largely in Switzerland and Portugal. He has two sons, Prince Irfan and Prince Sinan.
- Princess Zahra: The eldest child of the late Aga Khan IV. She’s heavily involved in the health and education side of the family’s foundations.
- Prince Hussain: Known for his incredible photography and his work with oceanic conservation.
- Prince Aly Muhammad: The youngest son, who has been focusing on documentary filmmaking and highlighting the work of the AKDN in remote areas.
- Prince Amyn: The late Aga Khan IV’s brother, who has been a constant figure in the family's cultural and architectural projects.
Why This Family Tree Actually Matters Today
It’s easy to look at a billionaire family with private jets and islands and think it’s just about wealth. But the aga khan family tree represents a unique model of leadership. They are the only Shia group led by a "living, present" Imam.

The wealth isn't just for show. The AKDN is one of the largest private development networks in the world. They run hospitals in Karachi, schools in Nairobi, and restored the parks of Cairo. They operate in a way that blends business with philanthropy—what they call a "social conscience."
Is it complex? Yes.
Is it controversial at times? Sure.
But it’s also undeniably successful at keeping a 1,300-year-old tradition relevant in a world of AI and space travel.
Understanding the Lineage Yourself
If you want to dig deeper into how these connections work, you don't need a degree in Islamic history. You just need to look at the transition points.
- Look at the 19th-century move to India. This is where the "Aga Khan" title becomes a global name.
- Study the 1957 Will. It shows how the family prioritizes competence and the needs of the time over strict birth order.
- Follow the AKDN projects. The family tree is best understood through the institutions they build.
The next time you see a headline about the Aga Khan, remember you're not just looking at a "celeb" or a "businessman." You're looking at the 50th link in a chain that has survived the rise and fall of empires, the transition from horses to private jets, and the move from ancient manuscripts to digital archives. It's a living history.
