2.  The Black Death was an outbreak of disease in the 14 th century that killed millions of people and had a lasting impact on Medieval Europe. Mass Burial, Plague, Belgium 1349. Unknown artist. What was the Black Death?

3. The Likely Culprit  Most historians agree that the Black Death was an outbreak of bubonic plague.  Bubonic plague is caused by a bacterium called Yersinia pestis.  It is transmitted to humans when they are bitten by an infected flea.

5.  Plague presents in different ways.  The disease can develop into other forms of plague, such as pneumonic plague, which can be transferred from person to person. "Dance of Death" (1493) by Michael Wolgemut Plague Varieties

8. TTracking the time frame for the spread of the plague across Europe helps to strengthen scientists’ and historians’ arguments for the origins of the Black Death. QQuestion: How might the map to the left help strengthen the accepted theory the plague infested rats helped cause the Black Death? AAnswer: The path plague follows is the general path of trade, moving north from the Mediterranean Sea. The Path of the Black Death

9.  Living conditions in medieval cities and towns were usually unhealthy.  Medieval Europeans did not have a high premium on personal hygiene.  Knowledge of effective medical techniques was minimal. Reasons for the Black Death’s Success

10.  Cities were very unhealthy places to live.  Waste was often dumped into the streets or at best open sewers.  Animals often roamed the streets freely.  Blood from butcher shops, dye from cloth makers, and other contaminates ran into the streets and eventually to the rivers.  Garbage was thrown into the streets with no plan for pick up.  Cities were often overpopulated. Crosses signified that urination was banned, but that didn’t always stop people. (Photo courtesy of the BBC) “I think I stepped in something…”

11.  Personal hygiene and general practices of good health were not up to the our standards today, but people in the Middle Ages did understand that being clean was a good thing.  Baths were taken 5 – 10 times per year.  Clothes were washed every month or so.  Diets were often poor. “What do you mean ‘I stink’? I’ll have you know, I bathed last month!”

12.  Medical expertise was lacking during the Middle Ages.  People in the Middle Ages often had superstitious remedies.  There was no knowledge of germs.  Commonly accepted practices, such as bloodletting, were usually more harmful than helpful.

13. Response to the Plague  Once the Black Death broke out, it was unstoppable, killing around 38,000,000 people.  Priests and doctors were dumbfounded as to how to stop it. The medieval equivalent of a biohazard suit – a doctor’s robes.

14. Response to the Plague  Doctors often gave poor advice such as warning against naps in the daytime, or even bathing.  Priests taught that the Black Death was a punishment from God.

15. Response to the Plague  Some people went so far as to whip themselves repeatedly in order to try and appease God and end the plague.

16.  Death became a constant companion to people in the Middle Ages. Their attitude and feeling of helplessness became evident in art and culture. Response to the Plague

17.  Conditions were horrible. Entire city districts were shut off due to outbreaks. Some towns were completely abandoned as people died or left to find refuge in the country. Response to the Plague A picture of monks carting off the dead. The clergy was hit especially hard during the plague.

18. Impact of the Plague  The Black Death did have at least one positive impact on Europe. Because there were fewer people to do work, peasants gained more leverage against nobles, and could demand more money or privileges.
