A new study challenges the long-held view that the 1820 epidemic in Mallorca was a classic outbreak of bubonic plague, according to Servimedia.
The research, reported by the Spanish news agency, suggests the event—often described as the last major plague epidemic in Europe—may not fit the traditional profile of the disease. The study's findings were also covered by outlets including Sinc, EL PAÍS, ABC, and Diario de Mallorca.
Historians and scientists have typically classified the 1820 Mallorca outbreak as bubonic plague, a bacterial infection transmitted by fleas carried on rats. The epidemic is known to have killed more than 2,400 people, according to Diario de Mallorca's reconstruction of the event two centuries later.
The new analysis questions whether the disease's transmission patterns and symptoms align with what is known about classical bubonic plague. Reports indicate the study may point to a different or mixed form of the illness, though the specific evidence and methodology behind the conclusion were not detailed in the available summary.
The research also sheds light on how Mallorca responded to the crisis at the time. ABC reports that authorities imposed lockdowns and used oil-based rubs as part of their containment measures, offering a glimpse into early 19th-century public health practices during a major epidemic.
The study adds to a growing body of historical epidemiology that re-examines past disease outbreaks using modern scientific methods. By revisiting centuries-old records with fresh analytical tools, researchers can sometimes overturn assumptions about how diseases spread and how past societies coped.
What to watch next: Further details from the study may clarify whether the 1820 Mallorca outbreak was caused by a different pathogen entirely, or whether it combined multiple forms of plague.
