When was the Black Death first introduced to Medieval Europe?

       The Bubonic plague, or Black Death was first introduced to medieval Europe in 1348 A.D. Historians think that the plague was brought from trade ships coming from Asia. But it wasn't the trade ships that caused the disease, it was the deadly rats aboard. These rats weren't born with disease in them, they were infected by fleas. The fleas were infected by the disease, and when they bit the rat, the rat would get the disease. Then the rat would go on the trade ships, usually attracted to some kind of food on the ship. When the ships would arrive to Europe, the rats would be released from the ships. Then the rats would go and bite people once off the ships.

       As soon as the person was bit, the germs from the flea that went through the rat, were  inside you. Then the germs would travel through all of your body. This immediately made you sick, and gave you a lot of painful symptoms. Once you got this disease, you were promised death. Almost nobody survived the epidemic. Most people who caught the disease, were dead within a week or less, depending on which plague you were infected by.
