In the high summer of 1789, between roughly 17 July and 6 August, a wave of panic swept across the French countryside on a rumor that had no body behind it: that bands of armed “brigands” — hired, it was whispered, by vengeful aristocrats — were marching on the villages to burn the ripening grain and slaughter the peasants who had begun to defy their lords. No such army existed. The brigands were never found because they were never there. Yet within three weeks the fear had run through most of the provinces of France, arming villages, emptying others, and turning peasant fury on the manor houses and the parchments that recorded feudal dues.
This episode, which French historians call the Grande Peur, the Great Fear, is one of the best-documented mass panics in the historical record, reconstructed in extraordinary detail by the historian Georges Lefebvre in his 1932 study. Its course is known almost village by village. It did not radiate from a single source but ignited in several distinct regions and spread outward along roads and rivers, each frightened community passing the alarm to the next — and, in a cruel feedback, armed peasants mustered against the phantom brigands were themselves mistaken for brigands by the next village down the road, which then took up arms and sent the panic onward.
The Great Fear caused real damage and a small number of real deaths, but its lasting consequence was political. The countryside in revolt — attacking châteaux, burning the feudal registers, refusing dues — confronted the new National Constituent Assembly in Versailles with a crisis it could not ignore. On the night of 4 August 1789, partly to quiet the rural storm, the Assembly voted to dismantle the feudal regime. A delusion about an invisible enemy thus became one of the proximate causes of the legal abolition of French feudalism.
This dossier treats the Great Fear as a closed episode with a known ending. The terror was groundless; the brigands were a rumor; and within weeks the fear had exhausted itself. What it reveals is not foolishness but a mechanism — how, in a season of hunger, political upheaval, and broken authority, a frightened population can manufacture and transmit a threat at the speed of a galloping rider, and act on it with real and irreversible force.
Between 1788 and 1790, London was gripped by fear of a phantom assailant the newspapers christened the “Monster”: a man said to approach well-dressed women in the street, insult them, and slash their clothing and their bodies — most often the thighs and buttocks — with a blade before vanishing. Over fifty women reported such attacks. In the spring of 1790 the panic reached its height, and on 13 June a 23-year-old Welsh artificial-flower maker named Rhynwick Williams was arrested after one victim, Anne Porter, identified him in a London park. He was tried at the Old Bailey, convicted, and imprisoned for six years. The reported attacks then largely ceased.
The verdict of history is more troubled than the verdict of the court. Williams was convicted on evidence that contemporaries and later historians have found seriously deficient. He had alibi witnesses for the attack on which the case against him was strongest — fellow workers who swore he had been making artificial flowers at the time. Descriptions of the Monster given by victims did not match him. Some women who had reported attacks and later saw him in court said he was not their assailant. A pamphlet by the writer Theophilus Swift argued his innocence at the time. Reports of further attacks persisted after his imprisonment, when he could not have committed them. The historians who have examined the case most closely regard Williams as a probable scapegoat — a real man punished to satisfy a frightened city — and that doubt must sit at the center of any honest account.
The episode is now read as a phantom-attacker panic: a genuine fear, fed by lurid press coverage and by a large cash reward, that almost certainly outran whatever real assaults may have occurred. The reward, posted by the merchant John Julius Angerstein, proved especially corrosive. The prospect of money produced a wave of accusations; men were dragged before magistrates, mobs harassed strangers, and some “victims” were later shown to have invented or exaggerated their injuries. Whether a single attacker ever existed remains uncertain. What is certain is that a city’s terror produced a conviction that the evidence did not support.
This dossier treats the London Monster as a closed episode with a sober and uncomfortable ending. The panic broke when a man was found to blame, not when the truth was established. The harm it left includes the women who were genuinely frightened, the strangers menaced by mobs, and — soberly — Rhynwick Williams, who served six years on proof that may not have been sound.
