When Princess Diana’s car crashed on August 31, 1997, the world was in shock for a while. She was much more than just a famous royal. To many people, Diana felt different from the rest of her family: warmer, more human, and more approachable. That’s why everyone loved her.
Her funeral was watched by millions, but it didn’t take long for heartbreak to turn into suspicion. People started asking questions. Some details of her death did not add up, leading many to speculate about the circumstances surrounding it and whether foul play was involved. Was there more to the story?
Diana’s case was quite unique in terms of conspiracies, as it had multiple theories that continue to spark discussion.
British special forces did it
At a certain point, a conspiracy theory surfaced involving the SAS, Britain’s elite special forces unit. It blew up after a woman identified only as “Sarah” claimed her ex-husband, a sniper nicknamed “Soldier N,” had been somehow involved in Diana’s death. According to her, an SAS soldier used a bright flash of light to blind the driver as the car entered the Pont d’Alma tunnel, causing the fatal crash.
It sounds like something straight out of a thriller novel, which is probably why people wanted it to be true. But at the time, the official investigation had already concluded that Diana’s driver had lost control before the car even entered the tunnel. In the end, the SAS theory sounded like a cool story but didn’t have any substance.

The royals did it
This hypothesis is probably one of the most famous theories out there, mostly because it’s allegedly tied to Diana’s own words. Her former butler, Paul Burrell, revealed a note written by Diana in which she claimed her husband was planning an “accident” involving her car, supposedly to clear the way for Charles to marry Tiggy Legge-Bourke, who had worked closely with William and Harry.
This theory starts to break apart when you look closely. The official investigation found no evidence that Charles knew about the note or that he had any plans to cause that accident. Burrell also later admitted he had included some misleading elements in his testimony, which didn’t exactly help the credibility of the story. So this theory has been busted on paper, but people still think it’s viable.

The CIA did it
If the death of a famous person doesn’t have a “CIA did it” theory, is it really a conspiracy? In Diana’s case, some people believe it was an international operation and not just a family thing. Supporters of the theory claimed British authorities had somehow worked with the CIA to make the crash happen in Paris.
Harrods’ security chief, John Macnamara, reportedly looked into it on Mohamed Al Fayed’s behalf, but nothing solid came out of it. Naturally, the CIA dismissed the accusations, and the official investigation concluded there was no sign of cooperation between U.S. and British intelligence agencies.

Dodi Fayed’s father says Prince Philip did it
One of the loudest voices behind the conspiracy theories was Mohamed Al Fayed, the father of Dodi Fayed, who died alongside Diana in the crash. Mohamed was straightforward in his public assertion that Diana was pregnant and intended to marry his son. And then he pointed fingers at Prince Philip, who allegedly was against the idea of an Egyptian Muslim becoming a stepfather figure to Prince William and Prince Harry.
Accusations that are massive require evidence, of which Mohamed had none. The official 2008 inquest could not find any proof to support this conspiracy theory, concluding that neither Prince Philip nor any named individual had orchestrated Diana’s death.

The paparazzi did it
Out of all the theories, this one probably feels closest to reality. Or does it? There’s no denying that paparazzi played a role in the chaos surrounding Diana’s final moments. It’s well-known that they followed her everywhere for years, hoping to get that juicy scoop. Because of that, some people claimed the paparazzi weren’t just creepy stalkers but that they deliberately caused the crash.
Given the tabloid industry’s well-known aggressiveness and intrusiveness, the theory may not seem entirely implausible at first glance. However, it still lacked one essential element: credible evidence of a coordinated effort. While such a scenario might appear possible in theory if paparazzi were willing to cooperate rather than compete for exclusives, the reality of the industry has historically been defined by intense rivalry and individual ambition, making that kind of organized collaboration far less likely.

While the paparazzi were not responsible for the car crash itself, their persistent intrusion undoubtedly added to the pressures Princess Diana faced during her lifetime.
