‘The Crown’ conspiracy theory explained: Who really was responsible for Princess Diana’s tragic death?

Ever since ‘The Crown’ landed in 2016, people haven’t stopped talking about it — apart from binge-watching the Peter Morgan series. The show digs into the British royal family’s private and public dramas, weaving together real history and dramatic imagination. And with the final season, especially those episodes about Princess Diana’s life and her heartbreaking death, old debates and wild theories are back in the spotlight.

What’s the truth? Who was really responsible for Princess Diana’s death? And why do so many people still believe there’s more to her story than what we’ve been told?

‘The Crown’: What’s it all about

At its core, ‘The Crown’ is Peter Morgan’s lush reimagining of royal life. In fact, as reported by Vanity Fair, after Queen Elizabeth II’s death in September 2022, Morgan paused production out of respect, calling the series "a love letter to her". He, in fact, wanted to stop making the show altogether, noting that the monarch's passing changed his perspective on continuing the hit royal drama.

For the unversed, ‘The Crown’ covers everything from Queen Elizabeth II’s coronation to the scandals and crises that rocked the monarchy. Sure, it pulls from actual events, but it’s not a documentary. The writers do their homework and use real sources, but when the facts run out, they fill in the blanks — sometimes with a heavy dose of creative license.

Running with that creative liberty has earned the show both applause and backlash. Historians and some people close to the royals have spoken out about how the line between fact and fiction can get pretty blurry.

How does ‘The Crown’ handle Princess Diana?

Princess Diana’s story takes center stage in the later seasons, especially season six. Emma Corrin (younger version in previous season) and Elizabeth Debicki (mature version) both step into her shoes, showing Princess Diana as she tries to rebuild her life after her divorce, her intense relationship with Dodi Fayed, and the suffocating press attention that followed her everywhere. Instead of sensationalizing her death, the show zooms in on her emotional struggles, family tensions, and what it felt like to live under that constant glare.

In the series, the creators tried to show what motivated her and the people around her. However, they didn’t set out to solve the mystery of her death. That’s for the official investigations and the history books.

Still, the show does spotlight the relentless paparazzi chase, something commentators and Princess Diana’s own family have blamed for the crash in Paris on August 31, 1997.

In reality, French and British authorities both found that the aggressive press and the driver’s actions played a huge role.

The official story vs. the conspiracy theories: What’s the bottom line

People have spent years digging into Princess Diana’s death: from the French police to the British Operation Paget inquiry, you name it. And still, conspiracy theories just keep popping up. The official version couldn’t be clearer: reckless driving caused the crash, not some secret plot.

However, people keep digging for other answers:

They say the royal family, or maybe MI6, planned it all. In their view, Princess Diana had to be silenced, either to protect royal secrets or to keep her from saying something explosive. Yet every official investigation has come up empty — no real evidence, just rumors and what-ifs.

Another popular theory is that Princess Diana was pregnant with Dodi Fayed’s child, and the couple was about to announce their engagement. And this was something the establishment supposedly couldn’t stomach. ‘The Crown’, in fact, touches on this rumor, but medical records and expert testimony say flat-out — she wasn’t pregnant.

There’s also talk that Henri Paul, the driver, was working for British intelligence. A former MI6 officer claimed this, but investigators looked into it and found nothing to back it up.

Then there’s the story about the mysterious white Fiat Uno, or a blinding flash right before the crash. A few eyewitnesses claimed they saw something like that, but when investigators looked into it, their stories just didn’t hold water.

Why these conspiracy theories persist

Here’s the thing: conspiracy theories love a vacuum. When the facts feel incomplete, and emotions run high, people start looking for hidden stories. Princess Diana’s death shook the world, and it’s no surprise that rumors and alternative theories have held on for so long.

Despite all this talk, both French and British investigators found nothing to suggest anyone set out to harm Princess Diana. No evidence of foul play. No secret plot.

‘The Crown’ doesn’t dodge all that suspicion and heartache; it really digs into the mess of emotions and the rumors swirling around. But it never pretends those theories are gospel. Instead, it focuses on what Diana actually went through: fighting with the press, dealing with relentless pressure, and just trying to live her life near the end.

That’s what pulls you in. The show mixes true events with drama, sometimes filling in the gaps when nobody really knows what happened behind closed doors. Still, it handles Diana’s story carefully, never losing respect for her. And when it gets to her death, it doesn’t dance around it: it’s clear — this was a heartbreaking accident, not some elaborate plot.
