The first biological weapon used in war is widely considered to be during the Siege of Caffa in 1346, when Mongol forces reportedly catapulted the bodies of plague victims into the besieged city. This act is believed to have contributed to the spread of the Black Death in Europe. Additionally, throughout history, various cultures have used biological agents, such as poisoned food or water, to harm enemies, but Caffa is often highlighted as a significant early example of biological warfare.
Attacking armies, specifically the Mongols, used their plague-infected soldiers as biological weapons against the Italian merchants in Caffa by catapulting the bodies of the deceased into the city. This tactic aimed to spread the bubonic plague among the inhabitants, creating chaos and weakening their defenses.

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. It is thought that the disease originated in the Far East, and was spread along major trade routes to Caffa, where Genoa had an established trading post. When it became clear that ships from the East carried the plague, Messina closed its port.
