In the early 2000s, The Da Vinci Code was everywhere. Dan Brown’s novel – and its subsequent film adaptation – popularised the idea that Jesus Christ fathered children whose descendants have lived among us for millennia. The Da Vinci Code is a work of fiction, but could the theory underpinning it be true?

In this episode of History’s Greatest Conspiracy Theories, Professor Helen Bond, an expert on early Christianity, joins Rob Attar to investigate the concept of the secret bloodline of Jesus.

As recent years attest, royal scandals have a habit of coming to light. But what if the mother of all royal scandals is still waiting to be revealed? Could it be that an heir to the British throne, Prince Albert Victor, lived a double life as a serial killer?

On 20 July 1969, American astronaut Neil Armstrong famously took one giant leap for mankind. The moon landing may well be the most iconic moment of the 20th century, but did it even happen at all? Might NASA and the US government have been so desperate to overtake the Soviets in the space race that they faked the entire thing?

In the final episode of season 2 of History’s Greatest Conspiracy Theories, Rob Attar is joined by spaceflight expert Francis French to consider why millions of people think the moon landing took place in a studio, rather than in space.

In the early 14th century, the Knights Templar were suppressed, and the 200-year history of this military religious order came to an abrupt end. Or did it? What if some of the Templars escaped persecution, and continued to operate secretly until the present, holding on to precious religious relics and maybe even discovering America?

In this episode of History’s Greatest Conspiracy Theories, Rob Attar is joined by medieval historian Steve Tibble to explore why myths have surrounded the Templars since the Middle Ages – and explain how Rosslyn Chapel and the Holy Grail fit into the story.

First published in Russia in 1903, The Protocols of the Elders of Zion purported to demonstrate evidence of a global Jewish conspiracy. Though it has repeatedly been proven to be a forgery, the text has helped fuel antisemitism across the world, from Henry Ford in America, to Nazi Germany and anti-Jewish hatred today.

In this episode of History’s Greatest Conspiracy Theories, Rob Attar speaks to Professor Pamela S Nadell about why the infamous tract has proven so popular and how it connects to other antisemitic ideas.

In her most famous speech, delivered on 9 August 1588, Queen Elizabeth I declared that she had the "heart and stomach of a king". Was that just rhetoric? Or could England’s iconic Tudor queen actually have been a man masquerading as a woman?

In this episode of History’s Greatest Conspiracy Theories, Tudor historian Tracy Borman speaks to Rob Attar about the bizarre 'Bisley Boy' conspiracy theory that was popularised by none other than Dracula author Bram Stoker.

On 7 December 1941, Japan attacked the US naval base at Pearl Harbor. It’s one of the most notorious surprise attacks in history, but how much of a surprise actually was it? Did President Franklin Roosevelt know that the attack was coming and even encourage it as a means of propelling the US into World War Two? 

In the first episode of season 2 of History’s Greatest Conspiracy Theories, the Pulitzer Prize-winning journalist Steve Twomey joins Rob Attar to tackle the "back door to war" conspiracy theory, explaining why many
