The black death, aka the great plague, was a dangerous disease which caused the death of nearly a third of Europe. It started in 1347.
The black death comes from rats or other smaller mammals and rodents. The disease comes from their fleas, which carry the bacteria Yersinia pestis. But fleas can jump from place to place (like to humans), and when an infected flea bites somebody, it causes the disease. Rats were especially attracted to rubbish and waste, so the disease was common in cities.
EEEEEEK!!! DEATH! DISEASE!
Doctors were powerless against the disease because they knew so little about it. Many homemade cures included: writing "abracadabra" in a triangle, lucky hare's feet, dried toads, leeches, or pressing a plucked chicken on the sore until it died.

There are three types of disease: the Bubonic plague,the septicemic plague, and finally,the pneumonic plague. The bubonic plague is the most common type of plague. It is named after the one of its symptoms, buboes. The pneumonic plague is the most serious one. It occurs when the bacteria infect the lungs and cause pneumonia. The septicemic plague happens when the bacteria enter the bloodstream and multiply.
Many people were terrified of catching the disease, so they fled. Since the disease can be airborne, and there were so many outbreaks, anyone could catch it. In mid-July 1665, about a thousand people died weekly. By September, the number increased to 7000 per week. But little did they know that by running away and migrating, they were spreading the disease even more!
One of the only positives to this event was that the demand for workers was higher than ever. Lots of people had died, and most of the rest had fled. So for the ones that stayed, the pays were higher and working conditions better.
