The Facts

  • A U.S.-led research team verified the first Mediterranean mass grave linked to the plague of Justinian, which killed millions in the Byzantine Empire between the sixth and eighth centuries A.D. DNA from bodies at a burial site in Jerash, Jordan confirmed the grave represented a single mortuary event.
  • The research was published in the Journal of Archaeological Science in the February issue. DNA extracted from the teeth of victims confirmed the presence of Yersinia pestis, the bacterium that caused the plague, providing hard evidence that the pandemic occurred.
  • Jerash was a regional trade hub and the epicenter of the pandemic that raged from A.D. 541 to A.D. 750. The mass grave contained over 200 individuals who were buried simultaneously, signaling a sudden and catastrophic pandemic event.

The Spin


Narrative A

The Jerash mass grave proves the Plague of Justinian killed millions and devastated Byzantine society through rapid urban mortality. This archaeological evidence transforms genetic data into a human story, revealing how densely populated cities became death traps when mobile populations were suddenly trapped together. The discovery shows how ancient pandemics were catastrophic social events that fundamentally reshaped civilizations.

Narrative B

The Jerash findings refute plague denialism by providing hard evidence the outbreak occurred, but mass mortality doesn't prove societal collapse. A disease can rampage through populations, but ultimately, society can endure. When the world warmed slightly centuries later, the population of Europe rebounded and thrived.
