The Siege of Caffa, which took place from 1343 to 1346, was a significant military conflict where the forces of the Genoese faced off against the invading troops of the Golden Horde in the Crimean peninsula. This siege is notable not only for its military implications but also for being one of the events that facilitated the spread of the Black Death from East to West. During the siege, infected corpses were reportedly used as biological warfare, introducing the plague into the besieged city and ultimately contributing to the epidemic that ravaged Europe.
