The case record
What was reported?
Historical accounts describe an outbreak of prolonged dancing in Strasbourg in 1518. Its causes, scale and alleged mortality remain matters of historical interpretation.
City authorities reportedly attempted interventions that included providing space and music before turning towards religious remedies. These responses belong to a society in which illness, saints and communal distress were understood differently from modern clinical categories.
The range is a summer reporting window, not precise onset and cessation dates for every participant.

Evidence in the record
Chronicles, civic records and later compilations form the evidence. Historian John Waller’s analysis emphasises social suffering and shared religious expectations. Exact participant numbers and claims of numerous deaths should be treated cautiously because the documentary record is uneven.
Competing explanations
Official and research context
Waller proposes a culturally shaped psychological epidemic. This retrospective account is not a contemporary clinical diagnosis and does not establish precise death totals.
Conventional explanations
Collective stress and culturally shaped involuntary behaviour offer a conventional explanatory model. Ergot poisoning and organised ritual have also been proposed, but do not explain every feature straightforwardly. Retrospective diagnosis cannot be confirmed without contemporary medical observations of modern quality.
Arguments that remain contested
The experiences of individual participants and the reliability of later numerical claims remain uncertain.
