How a Month-Long Dancing Plague Drove Hundreds in 1518 to Dance to Collapse

Executive Summary

• In July 1518, the city of Strasbourg experienced the most infamous outbreak of the so-called Dancing Plague, when hundreds of residents began dancing uncontrollably for days or weeks, sometimes collapsing from exhaustion or dying.
• Contemporary accounts trace the episode to a woman known as Frau Troffea, whose unexplained dancing sparked a wave of imitation that spread through crowds and soon involved dozens—and eventually hundreds—of participants.
• City authorities initially followed medical advice rooted in humoral theory, building stages and hiring musicians so sufferers could “dance out” the illness, but the strategy intensified the outbreak rather than curing it.
• Religious interpretations also shaped the response: many believed the phenomenon was punishment from Saint Vitus, leading officials to send afflicted dancers to his shrine for ritual healing.
• Modern historians, especially John Waller, argue the event was likely a form of mass psychogenic illness or collective hysteria, fueled by social stress, famine, disease, and powerful cultural beliefs in supernatural punishment.
