WORLD HISTORY

Detailed explanation-1: -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).

Detailed explanation-2: -It was transmitted to Europe in 1347 when a Eurasian army attacked the Genoese trading port of Kaffa in Crimea. Losing soldiers to the disease, the army catapulted plague-infected corpses into the town in an attempt to infect their enemies.

Detailed explanation-3: -Plague bacteria are most often transmitted by the bite of an infected flea. During plague epizootics, many rodents die, causing hungry fleas to seek other sources of blood. People and animals that visit places where rodents have recently died from plague are at risk of being infected from flea bites.

Detailed explanation-4: -The plague caused an epidemic in China in the 1330s, and again in the 1350s, causing tens of millions of deaths. The 1330s outbreak also spread west across Central Asia via traders using the Silk Road.

Detailed explanation-5: -In 1347 a Genoese ship from Caffa, on the Black Sea, came ashore at Messina, Sicily. The crew of the ship, what few were left alive, carried with them a deadly cargo, a disease so virulent that it could kill in a matter of hours.
