King Charles has officially granted the stlye of ‘His Highness’ to Prince Rahim Al-Hussaini Aga Khan V, marking his accession as the 50th hereditary Imam of the Shi’a Ismaili Muslim community. This royal recognition follows a long-standing tradition of British Monarchs bestowing the title upon Ismaili Imams, hereditary spiritual leaders.
The designation of ‘His Highness’ was first accorded to Aga Khan I in the 19th century, in recognition of his spiritual leadership and his contributions as a religious figure of global importance. Over the years, this honour has been reconfirmed after each succession, highlighting the enduring relationship between the Crown and the Ismaili Imamat.
Historical records show that Queen Victoria granted the title to Aga Khan III in 1886 when he was just nine years old, the year after his accession as Imam. Elizabeth II continued the tradition in 1957, conferring the title on Aga Khan IV shortly after he succeeded his grandfather. Now, King Charles III upholds this royal custom by granting the same honour to Aga Khan V.
The Ismaili Imams have historically served the Crown, particularly in India and Afghanistan.
The title also acknowledges the Imam’s role in interfaith dialogue, education, healthcare, and socio-economic development, areas where the Ismaili community has made contributions worldwide.
The late Aga Khan IV was particularly known for his diplomatic engagements and international statesmanship, enjoying a close personal relationship with both Elizabeth II and Charles III. His work was celebrated by the UK Government, including state-hosted events for his Golden and Diamond Jubilees and his recognition with a Knighthood.
Additionally, Aga Khan IV served as the Founding Patron of The King’s Trust, further cementing the ties between the Ismaili Imamat and British institutions.
Aga Khan IV and his entire family, including Aga Khan V and his children, are British citizens. Prince Rahim Aga Khan’s mother, as well as his late paternal grandmother, were British.
