Recorded sources

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that the Black Death of the 1340s was caused by a volcanic eruption?

No. Multiple reference and peer-reviewed sources state the Black Death of the 1340s was bubonic plague caused by the bacterium Yersinia pestis, spread by fleas; none attribute it to a volcanic eruption.
