On January 16, 1926, Britain received some extremely disturbing news. A demonstration by unemployed workers had erupted into a violent uprising in London. Rioters were attacking government buildings. A government minister had been hanged in the street. The Savoy Hotel had been blown up, and the Houses of Parliament were being demolished by artillery fire. Then came the announcement that must have convinced listeners that civilization itself was drawing to a close: Big Ben had been destroyed by trench mortars.

All of this was reported over the BBC, delivered in the reassuringly authoritative tones of a news announcer who sounded as though he had personally witnessed the destruction of the British Empire and was prepared to provide a detailed architectural commentary on the ruins. There was just one small problem. None of it was true.

London was perfectly fine. Parliament was still standing. The Savoy Hotel remained open for business, and Big Ben continued to tell the time, apparently unaware that it had been blown to pieces. The entire catastrophe was the invention of a Roman Catholic priest named Ronald Knox, whose 17-minute satirical broadcast, “Broadcasting the Barricades,” had been intended as a humorous parody of radio news reporting.

Unfortunately, some listeners failed to appreciate the distinction between a fictional revolution and an actual one. Worried telephone calls reached the BBC, newspapers, and other authorities. The broadcaster found itself having to reassure people that the capital of the United Kingdom had not been reduced to rubble. And here is the remarkable part: this happened twelve years before Orson Welles famously convinced some American radio listeners that Martians were invading New Jersey.

Meet Father Ronald Knox: Priest, Scholar, Detective Novelist, and Accidental Destroyer of London

Ronald Arbuthnott Knox was born in 1888 into a distinguished English family. His father was an Anglican bishop, and Knox initially followed him into the Church of England’s ministry before converting to Roman Catholicism and being ordained a Catholic priest in 1919. He was also an accomplished classical scholar, theologian, literary critic, translator, and author of detective fiction. He would eventually produce a new English translation of the Bible and become one of Britain’s best-known Catholic intellectuals.

Knox clearly had no shortage of worthwhile ways to spend his time. Confusing radio listeners just happened to become one of his more memorable extracurricular achievements.

Knox was particularly interested in detective fiction. His first detective novel, The Viaduct Murder, appeared in 1925, and in 1929 he formulated his famous Ten Commandments of Detective Fiction, a collection of rules intended to ensure that mystery writers played fairly with their readers. Among other things, Knox believed that a detective story should provide enough clues for the reader to solve the mystery without resorting to ridiculous last-minute revelations. Considering what happened during his radio broadcast, one might argue that he should have added an eleventh commandment: When telling people that Parliament has been destroyed, make certain they understand that you are joking.

How a Fictional Revolution Became Breaking News

On Saturday evening, January 16, 1926, Knox delivered his broadcast from the BBC’s Edinburgh studios. The program began at approximately 7:40 p.m. and was relayed to listeners through several BBC stations, including London. Radio broadcasting was still relatively new, and the British Broadcasting Company, as the BBC was then officially known, was experimenting with the possibilities of the medium. One of its principal ambitions was to educate the public, preferably while maintaining the air of solemn dignity that came naturally to an organization run by people who believed broadcasting was a matter of national importance. Knox decided that this approach was ripe for satire.

His program began with a fictional academic delivering a thoroughly tedious lecture about eighteenth-century literature. The professor, William Donkinson, spoke with an exaggerated lisp, discussed literary developments, and eventually disappeared into a coughing fit. Then the announcer took over, and at first everything sounded perfectly ordinary. There were cricket scores, a report about a child rescued from the Thames, and other routine items of the sort that listeners would expect from a conventional BBC news bulletin.

Then came reports that unemployed demonstrators had gathered in Trafalgar Square and were becoming increasingly unruly. The situation deteriorated rapidly. The crowd began attacking the National Gallery. It advanced toward government buildings in Whitehall. Before long, the demonstrators were preparing to destroy the Houses of Parliament with trench mortars.

At every stage, Knox maintained the measured, unflappable delivery of a professional newsreader. He reported catastrophic events with the same enthusiasm that might ordinarily accompany an announcement about a slight change in the weather. It was a master class in understatement, delivered while Britain was supposedly coming apart at the seams.

The Revolution Was Led by a Man Who Hated Waiting in Line for the Theater

If listeners had been paying particularly close attention, they might have noticed that the leader of the uprising was not exactly the sort of revolutionary figure who inspires monuments and lengthy political biographies. His name was Mr. Popplebury. More specifically, he was the secretary of the National Movement for Abolishing Theatre Queues.

Apparently, the movement had concluded that the most effective way to address the inconvenience of waiting to purchase theater tickets was to overthrow the British government. One can only imagine what Popplebury’s organization might have accomplished if someone had introduced him to reserved seating.

Knox repeatedly identified Popplebury by his full organizational title. The man could not so much as recommend the destruction of a national landmark without the BBC reminding everyone that his principal political concern involved excessive waiting times at places of entertainment. At one point, the demonstrators attacked the National Gallery. Rather than respond with appropriate horror, Knox’s fictional announcer paused to explain the building’s history, its architectural additions, and the paintings it contained.

The same thing happened when Parliament came under attack. Listeners received information about the building’s construction, dimensions, decorative features, and the limestone used to build it. This was a particularly pointed joke about the BBC’s determination to educate its listeners. Clearly, the collapse of the government was no excuse for neglecting a perfectly good opportunity to teach the public something about architecture.

For anyone interested in experiencing the absurdity firsthand, Knox’s surviving script can be read in its entirety. It was subsequently published under the title “A Forgotten Interlude” in his 1928 collection Essays in Satire.

Big Ben Falls, and the BBC Has a Minor Correction

As the imaginary uprising continued, Knox announced that the Houses of Parliament were being demolished with trench mortars. The clock tower collapsed, taking the famous clock and its great bell with it. There was, naturally, an immediate practical consequence: Big Ben would be unable to provide the customary time signal. Fortunately, the announcer explained, the time would instead be supplied from Edinburgh using Uncle Leslie’s repeating watch.

This was reassuring. The nation’s legislature might have been destroyed, but there was apparently no reason for the entire country to start showing up late for appointments. Meanwhile, the fictional Minister of Traffic, Mr. Wotherspoon, had been captured while attempting to escape in disguise. He was subsequently hanged from a lamppost in Vauxhall Bridge Road.

The BBC then interrupted its coverage with an important correction. More accurate information had become available: the minister had not been hanged from a lamppost after all. The instrument of execution was a tramway post. The distinction was evidently important enough to warrant an official correction, even though nobody seemed particularly concerned about the fact that the minister himself was now dead.

Then came the destruction of the Savoy Hotel, accompanied by a loud crash. The broadcast concluded with reports that the rioters were approaching the BBC’s own London station. The fictional revolutionaries had apparently decided that, having disposed of Parliament and several national landmarks, it was time to deal with the people reporting on their activities. And with that, the broadcast ended.

How Do You Blow Up a Luxury Hotel in a Radio Studio?

One of the more entertaining details of Knox’s broadcast is that the destruction of London was accomplished with rather limited technical resources. There were no elaborate recording facilities, digital sound libraries, or computer-generated explosions. The program was broadcast live, and its special effects were produced using the equipment available in an Edinburgh radio studio in 1926.

Fortunately, a resourceful BBC assistant named J. C. S. MacGregor was up to the challenge. As recounted in a 2026 centenary examination of the broadcast in The Observer, MacGregor used an orange box and a sack of broken glass to create the convincing impression that the Savoy Hotel was collapsing.

For listeners who had never encountered this kind of radio dramatization, the effects could be surprisingly persuasive. Combined with Knox’s authoritative delivery and the familiar sounds of a news bulletin, a wooden box and broken glass became powerful enough to demolish one of London’s most fashionable hotels. There is something wonderfully economical about that. Modern filmmakers require enormous budgets to destroy a city. Knox managed the job with household debris and a fruit box.

The BBC Had Already Told Listeners It Was a Joke

Perhaps the most remarkable part of the entire affair is that Knox had not actually attempted to deceive anyone. Before the broadcast began, George L. Marshall, manager of the BBC’s Edinburgh station, introduced the program as a humorous work of imagination. The fictional nature of the material was explained in advance, which makes the subsequent public confusion all the more remarkable.

Knox also filled his script with deliberately ridiculous names, repetitive announcements, ludicrous educational digressions, and an uprising led by a man whose primary grievance involved theater queues. Knox apparently believed these details were sufficient to prevent anyone from taking the performance seriously.

He was mistaken.

Some listeners had missed the introduction. Others apparently accepted the form of the news bulletin as evidence of its authenticity, even while the content became increasingly absurd. As the BBC’s own historical retrospective records, the broadcaster issued a clarification that evening and expressed regret that anyone had been distressed by the fictional program.

One can imagine the awkward conversation. A listener asks whether Big Ben has been destroyed, and the BBC explains that it was only a comedy broadcast. What about Parliament? Still standing. And the minister hanged from the tramway post? Also fictional, although the broadcaster can confirm that it was definitely a tramway post.

Snow, Missing Newspapers, and a Country Already on Edge

Why did an obviously satirical program cause so much confusion? Part of the explanation lies in the political atmosphere of Britain in early 1926. The country was experiencing serious industrial unrest, unemployment, and anxiety over political radicalism. The Russian Revolution of 1917 remained a vivid example of how quickly an established political order could collapse.

Britain would experience a major national crisis less than four months after Knox’s broadcast. On the night of May 3–4, 1926, the General Strike began, involving millions of workers and bringing much of the country’s industrial activity to a halt. Knox’s imaginary revolution therefore appeared in a country where political upheaval was not entirely beyond the realm of possibility.

There was also an unfortunate coincidence involving the weather. Snow and severe winter conditions interfered with newspaper deliveries in some parts of Britain during the weekend. For listeners eager to verify whether London still existed, the absence of their usual newspapers made the situation considerably more frustrating.

Imagine receiving news that the national legislature had been destroyed, deciding that you would feel better after checking the morning paper, and then discovering that your newspaper had failed to arrive. At that point, even a sensible person might begin wondering whether the newspaper delivery system was another casualty of Mr. Popplebury’s revolution.

Still, it is important not to exaggerate the public response. There were genuinely worried listeners, documented inquiries, and newspaper reports of confusion. That does not necessarily establish that the entire country descended into mass hysteria. The distinction matters because the newspapers themselves had a considerable interest in demonstrating that radio could be irresponsible, misleading, and potentially dangerous. Radio was becoming a serious competitor for the public’s attention, and the press was not necessarily inclined to interpret the incident generously. Apparently, alarmist reporting about the dangers of alarmist reporting was already a thriving business in 1926.

Did Britain Really Panic? The BBC’s Numbers Tell an Interesting Story

The newspapers described frightened listeners, anxious telephone inquiries, and rumors circulating long after the original broadcast. Some accounts suggested widespread panic, while others treated the entire episode as evidence that the BBC was becoming dangerously influential. But there is another side to the story. Journalist Paul Slade examined the surviving records in his detailed history, “Holy Terror: The First Great Radio Hoax.” According to figures reported by BBC managing director John Reith, the broadcaster received 2,307 favorable responses to Knox’s program, compared with 249 criticisms.

That works out to more than nine favorable responses for every negative one. Of course, those figures represent people who chose to respond, not a scientific survey of everyone who listened. Nevertheless, they suggest that the popular image of an outraged and terrified nation is considerably more dramatic than the surviving evidence warrants.

Plenty of listeners understood the joke and enjoyed it. In fact, the BBC was sufficiently pleased with the program’s reception that its programming officials subsequently discussed authorizing an April Fool’s Day broadcast along similar lines. This is not exactly the behavior one would expect from an organization traumatized by a disastrous national scandal.

Knox himself remained baffled by the controversy. He explained that he had conceived the idea while listening to election results and imagining what news bulletins might sound like if an actual revolution occurred. He believed that the increasingly ridiculous details would make the satirical nature of the performance perfectly obvious. Unfortunately, Knox had failed to account for one of the oldest principles of human communication: there is almost no statement so absurd that someone, somewhere, will not take it completely seriously.

Twelve Years Later, Orson Welles Borrowed the Idea

On October 30, 1938, a 23-year-old American actor and director named Orson Welles presented a radio dramatization of H. G. Wells’s science-fiction novel The War of the Worlds. Instead of portraying an imaginary communist revolution in London, Welles and his Mercury Theatre company presented an imaginary Martian invasion of New Jersey. The technique was strikingly similar.

The production began by simulating an ordinary radio program featuring dance-band music, which was repeatedly interrupted by seemingly urgent news bulletins. Reporters described an unfolding catastrophe. Real locations were mentioned, voices became increasingly alarmed, and convincing sound effects helped transform fiction into something resembling live news coverage. Once again, some listeners failed to recognize that they were hearing a dramatic performance. And once again, newspapers produced sensational accounts suggesting a much broader panic than the available evidence can conclusively establish.

Welles later acknowledged the connection between his production and Knox’s earlier broadcast. In conversations with filmmaker Peter Bogdanovich, subsequently published in This Is Orson Welles, Welles recalled hearing about the BBC program in which a priest described communists seizing London. He said the story helped give him the idea of attempting something similar on a larger scale, this time involving an invasion from outer space. Welles was only ten years old when Knox’s broadcast originally aired, and his later recollections were not entirely accurate about the timing. Nevertheless, the influence of the British broadcast on his thinking is supported by his own retrospective account.

Historian A. Brad Schwartz explores the relationship between the two productions in his research on the forgotten 1926 broadcast and the history of radio misinformation.

Knox was not, however, the only influence on Welles. As we previously explored in our article about Archibald MacLeish’s 1938 radio play Air Raid, the technique of presenting a fictional catastrophe through realistic news reports had also been developed by other dramatists. Welles and his collaborators brought these techniques together, replacing Britain’s unemployed revolutionaries with extraterrestrial invaders and creating one of the most famous events in broadcasting history. One might say that Knox helped establish the possibilities of fictional catastrophe reporting, while Welles recognized the considerable advantages of making the catastrophe considerably less likely to be interrupted by a speech about unemployment.

From London to New Jersey to a Deadly Broadcast in Ecuador

The influence of realistic fictional news reports did not end with Welles. In 1947, an American military radio station in Japan aired a fictional report about a giant sea monster attacking Tokyo. The broadcast used a similar combination of familiar news conventions and an increasingly alarming imaginary emergency.

Two years later, the idea produced far more serious consequences. On February 12, 1949, Radio Quito in Ecuador broadcast its own adaptation of The War of the Worlds, presenting the Martian invasion as though it were taking place locally.

This time, the consequences were not confined to anxious telephone calls and complaints about broadcasting standards. As detailed in our examination of the deadly Radio Quito broadcast of 1949, an angry crowd attacked the station’s building after discovering that the supposed invasion had been fictional. The building was set on fire, and people died.

What had begun as clever radio satire in 1926 had helped establish a dramatic technique that could entertain, confuse, and, under sufficiently unfortunate circumstances, produce genuine tragedy. The lesson was not that fictional news presentations were inherently dangerous. It was that audiences, broadcasters, and the surrounding circumstances could interact in unpredictable ways, particularly when a convincing presentation encouraged people to accept extraordinary claims without independent verification.

Can You Hear the Original 1926 Broadcast?

Unfortunately, no known recording of Knox’s original January 16, 1926, broadcast survives. Radio programs of the period were generally transmitted live, and the routine recording of broadcasts for posterity had not yet become standard practice. The good news is that the original script survives, allowing us to see precisely how Knox constructed his imaginary revolution, including the increasingly improbable news bulletins, architectural digressions, and spectacularly unsuccessful government response.

For those who would prefer to hear the story rather than simply read it, an excellent modern alternative appeared on the broadcast’s hundredth anniversary. On January 16, 2026, The British Broadcasting Century podcast released a centenary re-enactment and discussion of “Broadcasting the Barricades.” The episode includes an examination of the original broadcast and its historical significance with broadcasting historian A. Brad Schwartz.

It is a reconstruction, not a newly discovered recording of the original performance. That distinction is worth remembering, particularly in an article about people mistakenly believing that a realistic reproduction is the genuine article. History has a way of appreciating that sort of irony.

The Priest Who Accidentally Demonstrated the Future of Fake News

Ronald Knox lived until 1957, producing theological works, sermons, detective novels, and a celebrated English translation of the Bible. His reputation as a scholar and religious writer endured, and his contributions to detective fiction remain influential. Yet one of his most enduring contributions to popular culture came from a single Saturday evening when he decided to make fun of the BBC’s reporting conventions and the public’s tendency to believe whatever came through the wireless.

The resulting broadcast demonstrated something that remains disturbingly familiar a century later: the apparent credibility of information often depends as much on how it is presented as on whether it is actually true. Knox recognized the comic possibilities of a confident announcer, a familiar format, realistic sound effects, and a handful of recognizable locations. What he apparently failed to anticipate was that these same ingredients could transform even his most absurd inventions into something that sounded authoritative enough to be believed.

Of course, he was hardly the first person to discover that an audience could be persuaded by an elaborate hoax. As we explored in the Great Moon Hoax of 1835, newspapers had already demonstrated that supposedly respectable news reporting could convince readers that astronomers had discovered extraordinary creatures living on the Moon. What Knox did was adapt the old art of the believable hoax to a new technology, one that could deliver dramatic events directly into people’s living rooms while those events supposedly unfolded.

Today, we have social media, artificial intelligence, manipulated videos, deepfakes, and a virtually unlimited collection of people who are absolutely certain that whatever they just read on the internet must be true because someone posted it with a very serious expression. Knox required none of those resources. He destroyed Parliament, toppled Big Ben, blew up the Savoy Hotel, and persuaded some listeners that Britain was experiencing a revolution. He did it in seventeen minutes, using a microphone, a script, a wooden box, and some broken glass. And unlike many modern distributors of false information, he actually told everyone beforehand that he was making the whole thing up.

Apparently, even in 1926, paying attention to the disclaimer was considered entirely optional.
