War of the Worlds Broadcast

Orson Welles' 1938 radio drama, staged as breaking-news bulletins about a Martian invasion, allegedly sent thousands into the streets in panic. Whether the mass hysteria was as widespread as legend claims is itself disputed, making this a hoax about a hoax. It remains the gold st

Cottingley Fairies

Two young English girls photographed themselves with paper cutout fairies in 1917, and even Sherlock Holmes creator Arthur Conan Doyle championed the images as proof of the supernatural. Elsie Wright didn't confess the truth until 1983, sixty-six years later. The story endures as

The Great Moon Hoax

The New York Sun's 1835 series claimed astronomer John Herschel had spotted bat-winged humanoids and unicorns on the moon through a supertelescope, and readers devoured it. The paper never formally retracted the story, letting the hoax fade rather than confessing. It's an early m

Protocols of the Elders of Zion

This fabricated Russian document, purporting to reveal a Jewish plot for world domination, was exposed as plagiarized fiction by the Times of London in 1921. Despite total debunking, it went on to fuel Nazi propaganda and still circulates among conspiracy theorists today. It's th

Patterson-Gimlin Bigfoot Film

Sixty seconds of grainy 1967 footage showing a supposed ape-woman striding through Bluff Creek, California, launched a cryptozoology industry that never died. Roger Patterson took the story of how it was faked, if it was, to his grave, and the 'man in the suit' debate rages on. U

Loch Ness Monster 'Surgeon's Photo'

Donation of Constantine

This forged imperial decree, claiming Emperor Constantine ceded vast temporal power to the Pope, propped up papal authority for roughly seven centuries before Renaissance scholars exposed its anachronistic Latin. Few hoaxes have shaped actual European governance. It's less a pran

The Turk Chess Automaton
