In the annals of history, certain events defy easy explanation, capturing our imaginations with their sheer strangeness. Among these enigmatic episodes, the dancing plague of 1518 in Strasbourg stands out as a truly bizarre and unsettling phenomenon. Imagine a city gripped by an uncontrollable urge to dance, a mania that blurred the lines between joyous celebration and deadly affliction.
It began in July 1518, in the heart of Strasbourg, then part of the Holy Roman Empire. A woman named Frau Troffea initiated this peculiar chapter when she stepped into the street and began to dance. Not a celebratory dance, but a silent, convulsive movement of twisting, twirling, and shaking. For nearly a week, she persisted in her solitary dance, an inexplicable spectacle unfolding in the city’s thoroughfares.

Soon, Frau Troffea’s solo performance attracted an audience, and more alarmingly, imitators. Within days, dozens of Strasbourg residents joined her dance. By August, the dancing epidemic had engulfed an estimated 400 people. The city’s physicians, baffled by this mass hysteria, attributed it to “hot blood,” a medieval medical theory, and prescribed more dancing as the cure. This response, born from a lack of understanding, tragically amplified the crisis.
The city authorities, in a misguided attempt to manage the situation, constructed a stage and even hired musicians and professional dancers. The intention was to channel the uncontrollable dancing and perhaps encourage it to burn itself out. However, this only exacerbated the problem. The relentless dancing, fueled by music and social pressure, pushed the afflicted to their physical limits. Exhaustion became rampant, and people began to collapse. The relentless mania took a dark turn as dancers succumbed to strokes and heart attacks. Death became an undeniable consequence of this bizarre compulsion.
The Strasbourg dancing plague, while seemingly unbelievable, is well-documented in 16th-century historical records. It wasn’t an isolated incident either. Similar, though less severe, outbreaks of dancing mania occurred in Switzerland, Germany, and Holland. The Strasbourg event of 1518, however, remains the most significant and deadly example of this historical curiosity.
What could possibly drive people to dance to the point of collapse and death? Historians have proposed several theories to explain this perplexing event. One prominent theory, championed by historian John Waller, links the dancing plague to St. Vitus, a Catholic saint associated with protection against chorea, a neurological disorder causing involuntary movements. In the fear-ridden environment of 1518 Strasbourg, plagued by disease and famine, the St. Vitus superstition might have triggered a mass psychogenic illness, a stress-induced hysteria manifesting as uncontrollable dancing.
Another theory points towards ergot poisoning. Ergot is a toxic mold that grows on rye and other grains, especially in damp conditions. Ingesting ergot can cause a range of symptoms, including spasms, hallucinations, and convulsions. It is conceivable that the Strasbourg population, consuming contaminated rye bread, suffered from ergot poisoning, leading to the dancing mania. While this theory is compelling, some historians argue that the symptoms of ergot poisoning don’t perfectly align with the observed behaviors of the dancing plague.
The dancing plague of 1518 remains a historical puzzle. Whether it was a manifestation of mass hysteria fueled by religious superstition and societal stress, a case of ergot poisoning, or a combination of factors, the image of hundreds of people dancing uncontrollably in the streets of Strasbourg serves as a chilling reminder of the power of collective behavior and the mysteries that history still holds. The episode finally subsided in September when the surviving dancers were taken to a mountaintop shrine to seek divine intervention, marking the end of this extraordinary and tragic event.
