In the summer of 1518, something truly bizarre happened in Strasbourg, a city then part of the Holy Roman Empire. It started with one woman, Frau Troffea, who stepped into the street and began to dance.

She danced for days, her movements wild and desperate, with no music to guide her. Passersby were shocked and confused. But the strangest part was yet to come. Soon, more people joined her, and the dancing didn't stop.

The

Start of a Frenzy

Frau Troffea’s unstoppable dancing began in July

1518. It was a hot summer, and the city was already dealing with hardship. People were starving, and diseases were common. This made the sight of Frau Troffea dancing in the streets even more disturbing.

She seemed unable to stop, her body moving against her will. She danced until she was exhausted, only to get up and dance again. Her face showed pain and terror, not joy. It was clear this was not a celebration.

More and More Join In

Within a week, dozens of people had joined Frau Troffea. Then, the number grew to over 30 people. By August, the number had exploded to around 400 people. Men, women, and children were all caught in the strange dancing fit.

They danced in the streets, day and night. They danced until their feet bled, until they collapsed from exhaustion. Some even died from heart attacks, strokes, or sheer physical strain. The city officials didn't know what to do.

What

Did the Leaders Think?

The city leaders were baffled. They had never seen anything like it. Some doctors at the time suggested that the dancing was caused by “hot blood.” They believed that the best cure was more dancing.

So, they cleared open spaces, built a stage, and hired musicians. The idea was that if people danced until they were tired enough, they would be cured. This, sadly, did not work. If anything, it made the situation worse, encouraging more people to join the uncontrollable dance.

Theories

About the Dancing Plague

Over the centuries, many theories have tried to explain the dancing plague. One common idea is that it was a form of mass hysteria or a psychological condition. Stress and famine might have pushed people to a breaking point.

Another theory points to ergot poisoning. This came from a fungus that grew on rye bread, a common food. Ergot poisoning can cause hallucinations, muscle spasms, and strange behaviors, including convulsions that might look like dancing.

"The afflicted could not be kept from dancing by any force, but would… dance until they fell down from sheer exhaustion."

Could It Be Supernatural?

Some people at the time believed the dancing was caused by supernatural forces. They thought people were cursed or possessed by demons. This fear added to the panic in Strasbourg.

Others suggested it was a divine punishment for sins. These beliefs show how people tried to make sense of something they couldn't understand using the knowledge and superstitions of their time.

The Dancing Plague's End

Eventually, the dancing plague seemed to fade away. How it stopped is not entirely clear. Some believe that authorities changed their approach, perhaps by sending the dancers to shrines to pray or to a cooler climate.

Others think it simply ran its course, like a strange illness that eventually disappears. The last recorded instance of the dancing plague was in the 17th century, but the 1518 event remains the most famous and disturbing.
