“But if not for Ghengis and his progeny, the black death would never have decimated Europe.”
I’d like to hear more about that.
There is a good book on the subject, “Ghengis Khan and the Making of the Modern World” by Jack Weatherford. The monguls swept all the way to Europe which made the way safe for trade, resulting in postal delivery and modern banking. Unfortunately it also resulted in the transport of fleas from China that carried the black plague. I guess you’ve gotta take the bad with the good.
