A forgotten plague: making sense of dancing mania

In a spin: the mysterious dancing epidemic of 1518A forgotten plague: making sense of dancing mania

Introduction: On Christmas Eve in 1021, 18 people gathered outside a church in the German town of Kölbigk and danced with wild abandon. The priest, unable to perform Mass because of the irreverent din from outside, ordered them to stop. Ignoring him, they held hands and danced a “ring dance of sin”, clapping, leaping, and chanting in unison. The enraged priest, recorded a local chronicler, cursed them to dance for an entire year as a punishment for their outrageous levity. It worked. Not until the following Christmas did the dancers regain control of their limbs. Exhausted and repentant, they fell into a deep sleep. Some of them never awoke.

It might seem improbable to us, but there was nothing in this story that mediaeval people found hard to believe. Compulsive dancing joined that litany of natural and human disasters to be explained in terms of celestial or supernatural forces. But even if much of the chronicler’s account is clearly the stuff of legend, we should not dismiss it as purely invention. Plenty of sources indicate that this obscure chronicler may have embellished a real event. The Kölbigk incident is a contender for the first of the dancing plagues.


Later chronicles speak of a bout of unstoppable, and sometimes fatal, dancing in the German town of Erfurt in 1247. Shortly after, 200 people are said to have danced impiously on a bridge over the Moselle River in Maastricht until it collapsed, drowning them all. Likewise, dozens of mediaeval authors recount the terrible compulsion to dance that, in 1374, swept across western Germany, the Low Countries, and northeastern France. Chronicles agree that thousands of people danced in agony for days or weeks, screaming of terrible visions and imploring priests and monks to save their souls. A few decades later, the abbot of a monastery near the city of Trier recalled “an amazing epidemic” in which a collection of hallucinating dancers hopped and leapt for as long as 6 months, some of them dying after breaking “ribs or loins”. On a far larger scale was the outbreak that struck the city of Strasbourg in 1518, consuming as many as 400 people. One chronicle states that it claimed, for a brief period at least, about 15 lives a day as men, women, and children danced in the punishing summer heat. There were also several isolated cases during the 1500s and 1600s, from Switzerland and the Holy Roman Empire, of the mania gripping an individual or entire family.
