The black plague was the biggest epidemic in the world the black plague took place in 1347, the black plague killed over 200 million people in total in the world, In total it was thought that it killed 90% of the earth's population. 

There are three plagues in the black plague; the bubonic plague, the pneumonic plague and the septicemic plague. 

The most common way to get infected was flea bites and contact with others pared with the disease attacking the lymph nodes it spread quickly around the body and to others.

People treating the black plague wore special suits with bird-like beaks masked to protect them selfs, the masks were filled with herbs, spices and even things like honey, back then the theory bacteria and other viruses was not a thing so they thought that it was "poisoned air" causing the sickness hence the beak shape as they thought that that because of the shape it would make the "poisoned air" stay there longer and become clean and breathable.
