Ancient DNA shows plague resurged across Europe for 400 years after Black Death

University of Tartu researchers reconstruct 26 Yersinia pestis genomes revealing repeated, independent plague resurgences and a new dating method for ancient pandemics.

What to know

  • Researchers reconstructed 26 Yersinia pestis genomes from human remains at 11 sites in Estonia, Russia, England, the Netherlands, and Switzerland, spanning the 14th-18th centuries.
  • Genetic evidence indicates plague resurfaced independently in multiple parts of Europe rather than spreading repeatedly from a single surviving source.
  • A major lineage expansion around 1450-1500 split into three branches, possibly establishing new wild-rodent reservoirs, with the Great Renaissance Drought cited as a possible driver.
  • The team developed a new phylogenetic dating method to narrow the broad time windows typical of radiocarbon dating, helping link ancient genomes to specific historical outbreaks.

    Researchers unveil new method to date ancient plague genomes

    To overcome the broad radiocarbon dating windows typical of ancient samples, the team built a phylogenetic method to narrow dating estimates and link genomes to specific historical outbreaks, as detailed in the full Science Daily writeup.

    “With COVID-19, scientists could reconstruct the spread of individual strains extremely well because the genomes came with precise timestamps. For historical pandemics, those timestamps are often missing or may cover more than 100 years, which limits our ability to interpret the genetic data…”
    — Dr. Marcel Keller

    Study finds plague returned to Europe in waves for centuries

    Coverage begins circulating on a University of Tartu-led study showing plague repeatedly returned to Europe for more than 400 years after the Black Death, based on ancient DNA analysis.

  3. background

    Genomes reveal multiple independent plague reservoirs, not one source — The genetic evidence suggests plague resurfaced separately in different parts of Europe over hundreds of years rather than repeatedly spreading outward from a single surviving focus, with Estonia showing repeated reintroductions and a major lineage split around 1450-1500 potentially tied to the Great Renaissance Drought.

  4. background

    Team reconstructs 26 ancient Yersinia pestis genomes — Researchers analyzed DNA from human remains at 11 archaeological sites in Estonia, Russia, England, the Netherlands, and Switzerland, dating from the 14th to 18th centuries, to trace the Second Plague Pandemic.
