NARRATOR: In the mid-1300s a deadly disease killed about one-third of Europe's entire population. This pandemic, or outbreak, is known as the Black Death. At the time, many Europeans thought the Black Death was a punishment for their sins. Today, scientists think it was an outbreak of plague. Plague is caused by bacteria that infect rats. Fleas carry the infection from rats to humans.
