Answer 2

Something like one-third of the population of the European continent was wiped out by bubonic plague. It is now thought to have been trasmitted by fleas that bit rats and then somehow got transfered to Mongolian horsemen. As an interesting sidebar, the song "Ring Around the Rosie" originated during the time of the Black Death. Medicine had not progressed enough scientifically and they did not understand how disease spread (epidemiology).
