The Black Death appeared in Europe during October 1347 in Messina, Sicily. It arrived through trading ships that was very likely to come from the Black Sea, past Constantinople and the Mediterranean. This was silk, porcelain, which was from far away like China brought to the European customers. As soon as the people of Messina had realized the horrible sickness was coming from these ships, they quickly expelled themselves from the port, but it was too late already. The plague quickly spread through the city, and also spreading it to the nearby countryside.
While Sicily was suffering from these diseases. The trading ships brought the disease to other places around the Mediterranean, infecting the nearby islands like Corsica and Sardinia. Meanwhile, the plague has spread from Sarai to the Genoese trading station of Tana. At that time, the Christian traders were attacked by the Tartars and were raced to their fortress. The Tartars plagued the city in November, but because of the Black Death, it was cut short.
Before cutting off their attack, they brought dead plague victims into the city, hopping to infect the people. The defenders tried to avoid the plague coming to the people by throwing bodies into the sea, but they didn’t know that once the city has been hit by the plague, it cannot be removed. As the people of Kaffa started to fall for the disease, the traders entered the ships and sailed home. But they could not escape from the plague either. When they arrived to Genoa and Venice in January 1348, some passengers and sailors were left alive to tell the tale. Even a few plague victims could have the power to bring the plague to mainland of Europe.
