Did a Volcano Trigger Europe's Deadliest Plague?

New research suggests a volcanic eruption occurring around the year 1345 may have been the catalyst for Europe's most devastating pandemic, the Black Death.

Evidence from tree rings indicates that the eruption triggered a significant climate shock, resulting in drastically reduced temperatures and subsequent agricultural failures across the continent.

This dire situation forced populous Italian city-states to seek grain supplies from regions bordering the Black Sea. It is hypothesized that these imports inadvertently carried plague-infested fleas, thereby introducing the deadly disease to medieval Europe.
