The Black Plague was the deadliest Plague of all that lasted 1347 to 1350. It was a combination of three Plagues known as the bubonic, septicemic and pneumonic plagues. When you got the bubonic plague you started getting bubbles under your armpits. If the bubbles popped in time, you would survive the illness and if the bubbles didn't pop you would die. You got the septicemic plague when bacteria got into your bloodstream. People who felt normal died within hours. You got the pneumonic plague by breathing the air that a person who already had the pneumonic plague exhaled. The pneumonic plague was the deadliest plague because it was so contagious.
Most people in the middle ages thought that it was a disease caused by dirty air. Others thought that it was a punishment from god. Doctors didn't understand germs and bacteria but they did know that the plague was contagious so, they recommended that people who were not sick yet should not be with other people that much.
