I've always wondered if there was a link between "The Mongolian invasion wipes out ~25% of Asia" that happened shortly before "the Black Plague wipes out
~25% of Europe."
While I don't doubt the Mongol brutality, the death tolls just seem so much higher than similar events that an additional factor seemed plausible.
