Caffa and the Black Death: How a Siege Spread the Plague to Europe

Caffa (modern Feodosia, Ukraine) was a major Genoese trading port on the Crimean Peninsula. In 1347, it became a pivotal nexus in the spread of the Black Death to Europe.

Key Events

1. Trade Hub: Caffa connected Europe with the Silk Road, hosting merchants from Asia and the Middle East.
2. Initial Outbreak: Genoese ships from the Black Sea brought infected rats and fleas. The plague decimated the city.
3. Siege of Caffa: The Mongol army under Khan Janibeg besieged the city, trapping inhabitants and prolonging exposure.
4. Escape by Sea: Fleeing Genoese ships carried infected rodents and fleas to Mediterranean ports (Constantinople, Italy, France).
5. European Pandemic: This triggered the second wave of the Black Death, killing millions across Europe.

Historical Significance

Caffa's strategic location, the siege's containment effect, and the subsequent maritime dispersal made it a critical nexus in the pandemic's expansion into Europe. The event also gave rise to one of the earliest recorded instances of biological warfare—accounts suggest the Mongols catapulted plague victims' bodies into the city, though historians debate this claim.
