400 People Danced Until They Died

In July 1518, a woman named Frau Troffea stepped into a narrow street in Strasbourg, Alsace (then part of the Holy Roman Empire), and began to dance. There was no music. No celebration. She just danced.
She didn't stop. Not that evening, not that night, not the next day. For nearly a week, Frau Troffea danced without rest, her feet bloodied, her body trembling with exhaustion.
Then others joined.
Within a month, approximately 400 people were dancing involuntarily in the streets of Strasbourg. The city council, desperate for a solution, initially encouraged the dancing — they hired musicians and built a wooden stage, believing the afflicted needed to "dance it out."
Historical records suggest that at the peak of the plague, roughly 15 people per day were dying from heart attacks, strokes, and sheer exhaustion.
The dancing continued for roughly two months before gradually subsiding. Modern historians have proposed explanations ranging from mass psychogenic illness to ergot poisoning (a fungus on grain that produces chemicals related to LSD), but no single theory fully accounts for what happened. Five hundred years later, the Dancing Plague of 1518 remains one of the most bizarre events in recorded history.
