| Person | Age on 31 August 1997 | Birth date | Key context |
|---|---|---|---|
| Prince William | 15 | 21 June 1982 | Boarding at Ludgrove School; shortly before entering Eton |
| Prince Harry | 12 | 21 September 1984 | Boarding at Wetheral Preparatory School; transition to Ludgrove |
Immediate context and location when Diana died
At the time of Diana’s death, both princes were schoolchildren in the United Kingdom and not in Paris. Their father was on holiday with them at Balmoral Castle, a private Scottish estate owned by the Royal Family. The news was delivered by their father in person; household staff and royal officials have since described the careful, though inevitably traumatic, manner in which the princes were informed. In the immediate aftermath, the family remained at Balmoral before returning to London, and both boys continued their education with increased public attention.
Biographical snapshots: William and Harry in 1997
Prince William, born 21 June 1982
By 1997, William had been at Ludgrove School for several years and was preparing to transition to Eton College. He was the elder son and, from that autumn, the second in line to the throne after his father. His childhood had included the typical routines of a royal pupil, but also intensified media attention from an early age. At 15, he was in the early stages of adolescence, navigating school exams and personal identity within the framework of his future royal duties.
Prince Harry, born 21 September 1984
Harry, at 12, was in the final years of primary school and was about to move to Ludgrove. His school years had been marked by close family life at home at Kensington Palace and then by shared attendance at private schools with William. Losing his mother at such a young age meant that he had only fragmented, early memories of her, shaping a grief that was both personal and highly public.
Media environment and public reaction in 1997
The death of Diana unfolded in the pre-digital, 24-hour television news era. Global audiences watched live coverage from Paris, while the princes remained in Scotland with limited access to real-time media. Official communications from Buckingham Palace emphasized the princes’ privacy and their need to grieve away from the spotlight. Public reaction was intense, with spontaneous memorials at palaces across the UK, creating a contrast between the monarchy’s traditional protocols and an outpouring of popular empathy. The event marked a turning point in how the royal family managed public grief and media relations.
Long-term impacts on William and Harry
In the years after 1997, biographies and interviews have described enduring effects of losing Diana on both sons. William’s university years and early adulthood reflected a process of reconciling his public role with private loss, while Harry has spoken openly about the emotional repercussions and the way Diana’s death shaped his approach to mental health and family. Their respective marriages, fatherhood, and public work have all been framed, in part, by the absence of their mother and the subsequent reorganization of their family unit.
Key distinctions in memory and record
- William was three years older than Harry at the time, making him more cognitively aware of the circumstances, while Harry was younger and relied more on secondhand accounts and family explanations.
- Both were primarily schoolchildren at the time; their day-to-day lives continued with schooling and routines even as royal protocols adapted.
- Their ages are documented in official timelines from Buckingham Palace, Clarence House, and reputable biographies by royal correspondents.

Summary
At the moment Diana died, Prince William was 15 and Prince Harry was 12. They were with their father at Balmoral Castle and were informed in person. Their ages are well established from multiple official and biographical sources. This event became a defining moment in their lives, influencing their public paths, perceptions of royal duty, and personal approaches to grief and mental health.
