Does Friday the 13th Come from the Knights Templar?
The popular story, checked against the evidence.
The Real Story
- Popular claim
- Friday the 13th originates with the arrest of the Knights Templar in 1307.
- Verdict
- Modern myth
- The record
- The Templar link is a late-20th-century idea; the fear combines older superstitions about 13 and about Fridays.
A widely repeated origin story holds that Friday the 13th became unlucky because of a single historical horror: on Friday, the 13th of October 1307, King Philip IV of France ordered the mass arrest of the Knights Templar, who were tortured and later burned. It is dramatic, precise, and — as an explanation for the superstition — almost certainly a modern invention.
The arrest was real; the connection is not
The Templars really were arrested on that date, and it really was a Friday. But there is no trail of evidence showing that the superstition grew out of that event. For centuries afterward, no one seems to have linked the Templars to an unlucky Friday the 13th. The association is conspicuously recent, gaining wide currency only in the late twentieth and early twenty-first centuries — helped enormously by its appearance in a certain best-selling novel and its film. A coincidence of calendar plus a good story does not make an origin.
The real roots run separately
The genuine history is a merger of two older, independent superstitions. The number thirteen has long carried unlucky associations in Western culture — often connected to there being thirteen present at the Last Supper. Friday, quite separately, was regarded as an unlucky or ill-omened day in various folk and Christian traditions. Each fear is old and well attested on its own.
What is surprisingly young is the combination — the specific dread of “Friday the 13th” as a named unlucky day. That fusion appears to date only from the nineteenth century, and it was popularised in the early twentieth, notably by Thomas W. Lawson’s 1907 novel Friday, the Thirteenth. The superstition, in other words, was assembled from ancient parts fairly recently — and then, later still, given a false medieval pedigree.
The verdict
Modern myth, on the Templars — but with genuinely old roots underneath. The thirteen-and-Friday fears are ancient; their marriage into “Friday the 13th” is recent; and the Templar origin is a late gloss with no evidence behind it. It is the kind of layered claim we take apart across the real origins of everyday sayings.
