The "Dancing Plague" refers to a mysterious phenomenon that occurred in Strasbourg, France, in 1518, where numerous people began to dance uncontrollably for days. This unusual event involved dozens of individuals who reportedly danced without rest, leading to exhaustion and, in some cases, death. Historians suggest various explanations for this occurrence, including mass hysteria, ergot poisoning from contaminated grain, or psychological stress. Despite numerous theories, the exact cause of the Dancing Plague remains unclear, making it a fascinating topic in the study of historical medical anomalies and social behavior.
