The real 1629 mutiny behind The Traitors, and how a Dutch pitch became a global hit

Every time Alan Cumming sweeps into the Round Table in a cape that costs more than your car, you are watching the descendant of something genuinely horrifying. Not a party game. Not a psychology experiment. A real shipwreck, a real island and a real man who decided the best way to survive was to quietly arrange for everyone else not to.

The creator of the format has said so himself. So pull up a chair by the fire, pour something dark, and let us talk about the Batavia.

A maiden voyage that never arrived

The Batavia was a Dutch East India Company (VOC) ship heading for the Company's base on Java. On 4 June 1629, on her very first voyage, she ran onto Morning Reef in the Houtman Abrolhos, a scatter of low islands off the coast of what is now Western Australia. Accounts put the number aboard at somewhere around 320 to 340 people: sailors, soldiers, merchants and families.

Survivors struggled onto barren islands with almost no fresh water. The commander, Francisco Pelsaert, set off in an open boat to fetch help from Batavia itself, the port that is now Jakarta. It took him 33 days to get there. In his absence, the man left in charge on the islands was the undermerchant, Jeronimus Cornelisz.

If you are already muttering "oh no" at your screen, trust your gut. That is exactly the instinct the show wants you to have.

The quiet takeover

Cornelisz had already been plotting with the skipper to seize the ship, and its treasure, before it ever hit the reef. Stranded, with rescue possibly weeks away, he turned that plan on the survivors. He gathered a band of loyal followers, took control of the weapons and food, moved people he saw as threats onto other islands, and then began having people killed. The Australian National Maritime Museum puts the number murdered at 125; other accounts say at least 110. Men, women and children.

Here is the detail that makes a format designer sit up. The killings were not an open war between two sides that everyone could see. They were orchestrated by a small inner circle while the wider group was still, at least at first, working out who could be trusted. Sound familiar? Swap the islands for a Highland castle and the cutlasses for a murder note under a door and you are most of the way to a season premiere.

The first Faithful

Every good Traitors season needs a Faithful who figures it out, and the Batavia had one. A soldier named Wiebbe Hayes had been sent with a group of about twenty men to another island, supposedly to look for water and, the mutineers expected, to die there. Instead they found water, got wind of the massacre, and dug in. They held off the mutineers' attacks with improvised weapons and eventually captured Cornelisz himself.

When Pelsaert finally returned with a rescue ship, Hayes and his men reached him first and warned him. Justice was brutal and fast. Cornelisz and his closest accomplices had their hands cut off and were hanged on Seal Island; more mutineers were executed later in Batavia, and two were marooned on the Australian mainland. Hayes was promoted to sergeant. Only about 122 of the original company ever made it to Java.

Call it the original banishment, with considerably worse catering.

From history book to pitch meeting

Fast forward almost four centuries to the Netherlands. Marc Pos, a Dutch television creative, read about the Batavia in a history book, according to the Royal Television Society. What stuck with him was not the gore but the question underneath it: when the people on your own side start killing each other, who can you still trust?

Speaking to The Telegraph, as reported by HuffPost UK, Pos said his first version of the idea was called The Mutineers and was set on a ship, with eliminated players going overboard. RTÉ describes the same early concept with players walking the plank. Broadcasters were not convinced; HuffPost's account has the idea turned down around 30 to 40 times before anyone bit.

The format that eventually sold kept the paranoia and changed the setting. It also leaned into a game plenty of us played at summer camp or a slightly chaotic dinner party. The RTS traces the mechanics to Mafia, the parlour game where a hidden minority picks off the majority at night while everyone argues about it by day. Put Mafia and the Batavia in a blender and you get the whole shape of the show: a secret group, nightly killings, and a daytime vote where the majority is as likely to destroy itself as the enemy.

De Verraders

The show launched in the Netherlands as De Verraders on RTL 4 in March 2021, hosted by Tijl Beckand. It was created by Pos and Jasper Hoogendoorn at the Dutch production company IDTV, working with RTL's creative unit. IDTV is part of the All3Media group, which is the route by which a Dutch castle game ended up on screens around the world.

The core loop has barely changed since. Missions build a shared prize fund. The Traitors meet in secret and choose someone to murder. The survivors gather at the Round Table and vote someone out, and the banished player reveals whether they were Faithful or Traitor on the way out. The end game decides whether the Faithful split the money or a Traitor who made it to the final table takes the lot.

How it conquered the world

The British version arrived on BBC One on 29 November 2022, with Claudia Winkleman, a fringe, and a wardrobe of knitwear that deserves its own documentary. It was filmed at Ardross Castle in the Scottish Highlands, which became as much of a character as any player.

The American version followed on Peacock in January 2023, hosted by Alan Cumming and made by Studio Lambert. It shared the Highland setting and took a louder, glossier approach, with reality TV veterans alongside members of the public in season one. You can dig into every one of those seasons in the archive.

The Emmys noticed. According to the Television Academy, the US show has won Outstanding Reality Competition Program three years running, in 2024, 2025 and 2026, and Cumming has picked up the hosting Emmy each of those years too. The RTÉ press office, announcing Ireland's own version in 2025, put the franchise at more than 30 versions worldwide.

Why the Batavia still fits

It is worth being careful here. The show is a game, with welfare teams, a hotel and a host in a fabulous hat. The Batavia was a massacre of real people, and nothing in a Highland castle compares to it. What the format borrowed was the question, not the cruelty.

And the question holds up beautifully. On the Batavia, the people who survived were the ones who noticed the pattern, stuck together and refused to be split up. The people who did not were the ones who trusted the confident man in charge because he was in charge. Watch any Round Table and you will see exactly that split play out: the players who read behaviour, and the players who follow whoever talks loudest.

Next time a Faithful gets banished on vibes alone, spare a thought for Wiebbe Hayes, who did it the hard way. Then go and check how the fantasy scoring works, because on this site, being right about the Traitors is worth points.
