From 1347 to 1351, The Black Death (The “Plague”) originated in Central Asia. The Plague swept through Asia, Europe and Africa by way

of Mediterranean Trade Routes.

The Plague was at its worst between 1347 and 1351.

Page 3: The Plague

The Plague followed the Mediterranean trade routes from China to Europe and Africa.

The Plague was likely caused by a bacteria, Yersinia Pestis. Infected rats would carry fleas that would become infected. The disease was then passed on to humans through flea bites.

A flea like this would carry the bacteria and then the disease was passed on to humans through

flea bites.

Historians estimate that the world’s population may have been

reduced by 100 million people. Prior to the Plague, the world

population was about 450 million.

China lost about half of its population.

Europe lost about one-third of its population.

Africa lost about one-eighth of its population.

The Black Death was more devastating in areas with high population density which explains why it

was less prolific in Africa. Russia was also less affected perhaps due to its cold climate and size.

As people saw the disease spread faster in cities, many moved to the countryside where they believed

that they would be safer.

Because the cause of the Black Death was not known, and healers could do little to help the afflicted, several attempts were

made to stop the spread.

Monks and priests cared for the afflicted in

monasteries, but were therefore

more likely to get sick themselves.

Some Europeans blamed earthquakes for the

spread of the disease.

In many European communities, Christians believed that Jews were the cause and they blamed them for poisoning

wells. In France, some Jewish communities were exterminated, and some were burned alive.

As terrible as the Black Death was, there were some

changes that were beneficial.

Page 18: The Plague

In Europe, so many workers died, that the Nobles who owned the land were forced to pay higher wages to

attract workers. In other words, as the supply of workers went down, the wages they demanded went up.

Also, farms were forced to increase efficiency. Fewer workers meant that more advanced

farming tools had to be used to work the land. Plots also grew larger due to population loss.

Although the Plague was most severe in the 14th century, it came back in parts of Europe until the 17th century. Each time it killed fewer people. Historians

believe that there may have been two reasons for this.

Page 21: The Plague

First, natural selection may have helped. This means that people who were

naturally able to fend off the disease passed their genes to their offspring

resulting in a population that was less likely to contract the disease.

Second, hygiene habits and efforts to improve public health and sanitation had a significant

impact on the falling rates of infection.
