The Dancing Plague of Strasbourg, 1518
In the summer of 1518, a woman in Strasbourg began dancing in the street and could not stop. Within weeks dozens — and by some accounts up to 400 people — were dancing compulsively for days on end, some reportedly until they collapsed or died. The episode is firmly attested in city-council minutes, physician notes, cathedral sermons, and regional chronicles. It is not a hoax or a pure legend: something genuinely strange happened. The best modern explanation is mass psychogenic illness ("psychic contagion") fueled by famine, disease, and a widespread belief in St. Vitus's curse, rather than a supernatural cause or ergot poisoning.
