The Dancing Plague of 1518: Strasbourg’s Mass Hysteria Event
Introduction and Background
In the summer of 1518, a strange and inexplicable phenomenon swept through the city of Strasbourg in Alsace, France. Known as the “Dancing Plague,” this mass hysteria event saw dozens of people dance uncontrollively for days on end, with many succumbing to exhaustion or dehydration. The exact cause remains a mystery, but it has captivated historians and researchers for centuries.
Key Events and Dates
The Dancing Plague began in late June 1518 when a miller’s daughter named Frau Troffea stepped into the streets of Strasbourg and started dancing uncontrollably. Within hours, she was joined by others, and within days, an estimated 400 people were participating in what became known as the Great Dance or Seizure.
On July 13, 1518, a group of noblemen attempted to stop the dancers but were met with hostility from the crowd. The event gained significant attention, drawing crowds and media coverage even for the time. By August, many participants had died due to exhaustion and complications such as heart attacks or strokes.
Witness Accounts and Evidence
Local records provide vivid accounts of the dancing. A contemporary account described how “the women were more affected than men.” The dancers would spin in a circle for days on end without stopping, often collapsing from exhaustion but then rising again to continue their frenzied movements.
One witness, Martin Schreibers, wrote: “They danced and danced, some for three days straight, others up to seven or eight nights continuously. Many of them were so worn out that they could barely move.”
Investigations and Research
Historians have attempted to unravel the mystery behind this phenomenon. One leading theory suggests that ergot poisoning might have played a role. Ergot is a fungus that grows on rye and can cause symptoms such as convulsions, hallucinations, and involuntary movements.
In 1982, neurologist Richard A. Samek proposed that ergot was the likely culprit based on evidence of ergot alkaloids in the urine samples of dancers. However, this theory has not been universally accepted, with some researchers arguing for alternative explanations such as mass hysteria, social contagion, or even a religious phenomenon.
The Current Status and Ongoing Mystery
Despite extensive research, the exact cause of the Dancing Plague remains unknown. Modern historians continue to debate whether it was a genuine medical condition or a form of group hysteria exacerbated by societal pressures.
The incident has gained renewed interest in recent years, with scholars using it as a case study for understanding collective behavior and mass hysteria. While the evidence points towards ergot poisoning, other factors such as social stress, religious fervor, and psychological triggers are also considered plausible explanations.
Frequently Asked Questions
Q: Why did the Dancing Plague start?
A: The exact trigger remains unknown, but theories range from ergot poisoning in rye bread to social or psychological factors. A miller’s daughter named Troffea reportedly started dancing first, which then sparked a larger event.
Q: How long did the Dancing Plague last?
A: The Dancing Plague lasted approximately four months, from late June to early November 1518. It is estimated that several hundred people participated in the dance at various times over this period.
Q: Are there any known survivors of the Dancing Plague?
A: There are no reliable records of specific survivors, but given the large number of participants and the duration of the event, it is likely that many individuals recovered. However, some dancers did not survive due to exhaustion or complications from their prolonged dancing.
Q: What evidence supports ergot poisoning as a cause?
A: Neurologist Richard A. Samek proposed that ergot alkaloids were present in the urine samples of dancers. Ergot can cause symptoms like those observed during the Dancing Plague, including convulsions and involuntary movements.
Q: How has the Dancing Plague influenced modern understanding of mass hysteria?
A: The event is often cited as a classic case study for understanding how social and psychological factors can create widespread physical and mental phenomena. It continues to be used in academic discussions on group behavior and collective mental health issues.
