In the sweltering summer of 1518, the city of Strasbourg witnessed something that defied belief. It began with one woman stepping into the streets and dancing, not for joy or celebration, but seemingly against her will. Within days, dozens joined her, and by the end of the month, hundreds of citizens were writhing and spinning uncontrollably. They danced until their feet bled, until they collapsed from exhaustion, and, in some cases, until they died. This strange and terrifying event, known as the Dancing Plague of 1518 , remains one of history’s most haunting medical mysteries.
A study published in Frontiers of Neurology and Neuroscience examined this medieval epidemic as an early example of mass psychogenic illness , a condition where psychological distress manifests physically within a community. The researchers suggest that the people of Strasbourg, reeling from famine, disease, and deep religious anxiety, may have collectively experienced extreme stress that erupted as uncontrollable dancing. This intersection of social trauma and superstition turned one woman’s strange movements into a full-blown public crisis.
Strasbourg dancing plague 1518: A city on the edge
Strasbourg in the early 16th century was no stranger to hardship. Poor harvests, high grain prices, and outbreaks of disease had left the population malnourished and desperate. Many believed they lived under the shadow of divine punishment. When Frau Troffea, the first dancer, began her frantic movements, people didn’t think of medicine or madness. They thought of sin. Local chronicles record that the afflicted were encouraged to keep dancing, as authorities believed it was a form of penitence that might purge evil spirits.
As the days passed, the dancing grew impossible to ignore. Markets and squares filled with swaying, trembling figures, some laughing, others weeping or shouting prayers as if in a trance. Physicians were called, but their remedies, from bloodletting to music, only made things worse. Bands were even hired to “aid the cure,” their rhythms fuelling the frenzy rather than calming it.
What caused the dancing plague of 1518?
For centuries, historians and scientists have debated what caused this bizarre outbreak. One early theory blamed ergot poisoning , a toxic mould found on damp rye bread that can cause hallucinations and convulsions. While this might explain some of the delirium, ergotism also causes extreme pain and muscle contractions, symptoms that would make prolonged dancing nearly impossible.
Modern scholars lean toward psychological explanations. The most supported theory today views the 1518 outbreak as mass hysteria, triggered by collective trauma and religious fear. A society steeped in apocalyptic beliefs, facing starvation and disease, may have channelled its suffering into a contagious form of physical expression. In essence, they danced because their minds and bodies could not cope with reality.
The role of religion in the Strasbourg dance epidemic
Religious fervour played a central role in spreading the panic. Many believed that St. Vitus, the patron saint of dancers and entertainers, could curse people with uncontrollable movements if angered. When panic spread, the church organised processions and rituals to honour the saint, hoping to appease divine wrath. Ironically, these gatherings may have intensified the spread, not of disease, but of fear.
This episode reveals just how powerful belief and social suggestion can be. Similar outbreaks of collective behaviour have occurred throughout history, from fainting fits in convents to laughter epidemics in schools. Human beings are profoundly social creatures. Under stress, we mirror one another’s emotions, sometimes to the point of shared physical collapse.
The dancing plague and mass hysteria in modern times
While a city-wide dance plague feels unthinkable today, the psychology behind it remains deeply relevant. Mass anxiety, moral panic, and contagious fear still shape public behaviour, only now they spread through social media instead of city squares. The 1518 dancing plague reminds us that the human mind, when pushed to its limits, can blur the line between body and belief.
Five centuries later, the streets of Strasbourg are quiet, but the story lingers, a chilling reminder that under the right conditions, even reason can lose its rhythm. The dancing plague was not just a mystery of medicine. It was a reflection of human vulnerability, faith, and the strange ways we seek release from suffering.
