Plague (Yersinia pestis)

The Black Death has also been called the Great Mortality, a term derived from medieval chronicles’ use of magna mortalitas. This term, along with Magna pestilencia (“great pestilence”), was used in the Middle Ages to refer to what we know today as the Black Death as well as to other outbreaks of disease.

Having originated in China and Inner Asia, the Black Death decimated the army of the Kipchak khan Janibeg while he was besieging the Genoese trading port of Kaffa (now Feodosiya) in Crimea (1347). With his forces disintegrating, Janibeg used trebuchets to catapult plague-infested corpses into the town to infect his enemies.
