Similar to the more famous Dancing Plague of 1518 in Strasbourg, this earlier incident saw a group of children and adults taken by an uncontrollable urge to dance, seemingly possessed by an invisible force.

The event is a compelling example of mass hysteria and remains a topic of fascination for historians and psychologists alike.

The Outbreak in Erfurt

The Dancing Plague of Erfurt began in the summer of 1237 when a group of approximately 100 children, reportedly from nearby towns, began to dance wildly and uncontrollably through the streets of Erfurt. The children danced for several days, moving from town to town, and were joined by others who fell into the same frenzied state. Accounts describe the dancers as being in a trance-like condition, oblivious to pain and fatigue.

As the children danced, they sang strange songs and displayed odd behaviors, drawing the attention and concern of the townspeople. Attempts to intervene or stop the dancers were futile, as they appeared to be driven by an unseen compulsion.


Interpretations and Responses

The phenomenon of uncontrollable dancing, also known as choreomania, was not entirely unheard of in medieval Europe, but each outbreak was met with confusion and fear. The people of Erfurt, deeply religious and superstitious, sought explanations within their cultural and spiritual framework.

1. Religious and Supernatural Beliefs

Many believed that the dancers were possessed by demonic forces or that they had incurred the wrath of a saint, possibly St. John the Baptist or St. Vitus, both of whom were associated with dance and convulsions. Pilgrimages to holy sites and shrines were common, as people sought divine intervention to cure the afflicted.

2. Medical Theories

Medieval physicians had limited understanding of the condition. Some speculated that the dancers suffered from a form of “hot blood” or imbalance of the humors, common explanations for many ailments in that era. Herbal remedies and bleeding were often prescribed, though their effectiveness was dubious at best.

3. Social and Psychological Factors

Modern historians and psychologists view the Dancing Plague as a case of mass psychogenic illness, where psychological stress and social pressures manifest as physical symptoms. The 13th century was a time of significant hardship, with famine, disease, and social unrest potentially contributing to a collective breakdown.

Historical Context

The 13th century in Europe was marked by numerous social and environmental stressors. The region experienced frequent famines, outbreaks of disease, and the constant threat of conflict. In such a context, it is plausible that the psychological strain on communities could manifest in dramatic and unusual ways, such as the Dancing Plague.

Aftermath and Legacy

The Dancing Plague of Erfurt eventually subsided, much like it had begun—suddenly and without clear explanation. Some of the dancers reportedly collapsed from exhaustion and were cared for by local families and religious institutions. Others were taken to churches and shrines, where they were prayed over and treated by clerics.

The incident left a lasting impression on the collective memory of Erfurt and surrounding regions. It served as a cautionary tale about the mysterious and often inexplicable nature of human behavior. The Dancing Plague of Erfurt has been documented in various medieval chronicles, ensuring its place in the annals of history.

The Dancing Plague of Erfurt in 1237 is a fascinating example of mass hysteria and the complex interplay between mind, body, and society. While modern science provides some insight into the potential causes of such outbreaks, the full explanation remains elusive.
