8、 mid-1300s,the mystery and horror of the Black Death terrorized many Europeans into believing the end of the world was upon them.In terms of death rates,it remains the most destructive event in European history.At the same time,some historians link the ruin it caused with the Renaissance period,whic

9、h soon followed.Lasting from the late 1300s until the 1600s,the Renaissance was a huge cultural shift in Europe.It inspired great advancements in medicine,science,art,and philosophy.Renaissance means“rebirth”in French,and after the horror of the Black Death,a period of rebirth was precisely what Eur

14、 human history.Before the mid-1800s,some healers recognized that certain plant molds and other fungi attacked bacteria.In the 1800s,more research led to a better understanding of the link between microbes and disease.Then in the 1920s,Scottish biologist Alexander Fleming accidentally discovered a pl

15、ant mold that destroyed a dangerous form of bacteria.Out of his research came the wonder drug penicillin,which is capable of killing many forms of bacterial infection.Fleming was awarded the Nobel Prize in Medicine in 1945 for his breakthrough work.Alexander Fleming4The Plague ShipsThe scene and sme

16、ll must have been staggering.In October 1347,a dozen trading ships sailed into the port of Messina,Sicilypart of modern-day Italy.The vessels had made the long voyage across the Black Sea.The arrival of the ships likely caused excitement around the docks,as ships such as these often carried news and

17、 exotic goods from the East.Those who greeted them,though,got the shock of their livesand perhaps the cause of their deaths.Most of the crew aboard the ships were already dead.The sailors working the ropes and sails were in agony,oozing pus and blood from black boils on their skin.The citizens of Me

18、ssina had heard rumors of a terrible disease spreading in Asia.These ships and sailors brought a deadly,invisible cargo to Europethe plague.This outbreak of plague,later called the Black Death,rapidly spread across Europe and North Africa.Strangers unknowingly passed it to strangers,friends brought

19、it to friends,and ships carried it to unsuspecting ports where it found fresh victims.It left tens of millions of people dead.Rich or poor,royalty or peasantrynone were safe.It was one of the worst outbreaks of disease in history.13The aftermath of the Black Death had a big impact on survivors views

20、 about society and the meaning of life as well.Many questioned their belief in religion and the church.Some challenged their leaders,lords,and kings.The authority of powerful individuals had proven useless in protecting the people they controlled and ruled.There were many examples of important progr

21、ess in post-plague Europe.Agriculture improved as farmers experimented with better practices and equipment to grow more food with fewer hands.Public health and medicine also saw positive changes as more communities recognized the importance of sanitation and put in place better ways to limit and tre

22、at disease outbreaks.The invention of the heavy plow helped end food shortages following the plague years.It allowed farmers to till fields much faster by using horses rather than oxen to pull the plow.The Plague!Level Z15The Fleas of DiseaseIn the 1300s,no one had yet made the connection between ge

23、rms and illness.The idea that bacteria or viruses could cause a cold,the flu,or other sickness was unknown.No one had made the connection between the plague and fleas,either.It was not until 1894almost 550 years laterthat scientists identified the likely culprit:a bacterium called Yersinia pestis.Th

24、ese bacteria get into the digestive tract of a species of flea that feeds primarily on the blood of black rats and other rodents.Many historians believe the bacteria began killing off rodent colonies that they normally lived in.The fleas were then forced to go looking for other warm-blooded creature

26、rtage of workers.The absence of skilled artisans and laborers caused a crisis in manufacturing.Workers were able to demand better pay and treatment.Without enough peasants to work the fields,crops were left unplanted or unharvested.Livestock died from the plague or from a lack of tending.As a conseq

27、uence,Europeans suffered widespread food shortages and starvation.Peasants now had more bargaining power,however.Some moved from their home villages to where they were offered better opportunities.6The poor public sanitation and human hygiene of the 1300s did not help.Especially in overcrowded citie

28、s,human waste and garbage were often dumped in the streets.Bugs were regular houseguests,and getting bitten by fleas and other pests was an unpleasant fact of life.Not all researchers are convinced that fleas were the only source of the Black Death or even the main one.Many other diseases were capab

29、le of causing deadly outbreaks,including cholera and typhus.Some researchers argue that the outbreak in 1347 spread too fast and killed too quickly to be Yersinia pestis.They wonder if the Black Death might actually have been a deadlier microbe they have yet to identify.However,Yersinia pestis remai

30、ns the leading suspect,based on descriptions of the symptoms by people of the time.Archaeologists have also found the DNA of these bacteria in mass burial sites from the mid-1300s.What seems clear is that humans began passing this deadly disease to each other directly.A persons pus,blood,or saliva c

31、ould infect others it touched.A simple cough or handshake could transmit the sickness to the next victim.Once human-to-human contact began spreading the disease,it became all but unstoppable.11The AftermathImagine half the people of your town or city gone,shops closed,stores empty of food.That was t

32、he experience of many of the people who survived the worst period of the Black Death,from 1347 to 1353.Record-keeping in medieval Europe was spotty,so historians can only estimate the death count.There were about eighty million Europeans before the Black Death struck.Experts calculate that an astoni

33、shing 40 to 60 percent of those people died,though the death rate varied greatly by location.In Spain and southern France,the plague may have killed 75 to 80 percent of the population.In Germany and England,the rate may have been closer to 20 percent.Cities were usually the hardest hit,as the diseas

34、e spread easily in crowded,dirty neighborhoods.Nearly 60 percent of Londoners died,as well as half the residents of Paris.After 1351,the outbreak eased for reasons scholars are still investigating.Survivors may have built up immunity to the disease,or the bacteria may have changed into a less deadly

35、 form.Plague outbreaks happened again and again for the next five hundred years.None,though,ever matched the devastation of the Black Death.The Plague!Level Z17Death Stalks EuropeAt the time,there was no effective treatment for a disease as serious as the plague.Once a person was infected,the bacter

36、ia took three to five days to reveal themselves.As the illness ran its course,victims experienced headaches,fever,chills,diarrhea,vomiting,swelling,and intense pain.They might die quickly or live another three to five days,but historians estimate that only one in five people who got the symptoms sur

37、vived.Part of what made the plague so deadly was that it could come in different forms.In bubonic plague,Yersinia pestis bacteria first attack the lymph nodes in the neck,groin,and underarms.Lymph nodes are vital organs of the immune system that allow the body to battle disease.In response to the at

38、tack,the lymph nodes swell and blacken with poisoned blood and pus,becoming boils called buboes.The infected blood and other fluids eventually poison and kill the victim.The Black Death also seems to have taken the form of pneumonic plague.Victims of pneumonic plague do not develop buboes;instead,ba

39、cteria attack their lungs,causing them to bleed heavily,or hemorrhage.The Plague!Level Z110In many areas,Christian groups wrongly blamed Jews for causing the plague.Many Jewish communities were attacked and their people driven off or killed.The head of the Catholic Church,Pope Clement VI,issued a de

40、claration making it clear that Jews were not at fault and should not be victimized.During the mid-1300s,though,more than two hundred Jewish communities were wiped from the map of Europe.A few cities instead used common sense to try to control the disease.Port cities soon realized that visiting ships

41、 were a source of contagion and began to block those that came from plague-infected areas.Some port authorities imposed regulations requiring ships to wait forty days before being allowed to dock.The waiting period,or quarantine,was meant to confirm that the ships crew were plague-free before allowi

42、ng them to come in contact with local residents.Leaders in some areas also figured out that stopping the movement of people was the best hope of slowing the spread of the disease.Infected families were blocked from leaving their houses.Officials set limits on travel and trade to and from their citie

43、s.Work crews hurried to get victims buried as soon as possible,often in mass graves,for fear that their corpses could infect others.8Pneumonic plague can also spread through tiny drops of blood or saliva that become airborne when infected people cough.Some experts wonder if this is the form that all

44、owed the Black Death to spread as rapidly as it did.People infected with bubonic or pneumonic plague could also develop septicemic(sep-teh-SEE-mik)plague when bacteria multiplied in their blood.This form of plague would poison the victims bloodstream and was almost always fatal.By 1348,the Black Dea

45、th was spreading across Europe.Travelers,traders,and trading ships carried it to new areas.It often took weeks before an infected village,town,or city knew something was horribly wrong.By then,it was too late to do anything about it.By 1351,there was hardly a corner of Europe that the Black Death ha

46、d not reached.Filthy and crowded medieval towns allowed the plague to spread very quickly.9Panic and a PrayerOnce people realized that plague had reached their community,many panicked.Terrified families abandoned sick loved ones.Shopkeepers shut their doors.Doctors,clergy,and officials fled the plac

47、es and people they served.City folk escaped to the countryside,thinking it would be safer there.By fleeing,though,they often helped spread the disease.Because no one understood the causes of the Black Death,few people had effective ideas about how to fight or control it.Desperate people tried useles

48、s cures like strapping a skinned chicken to the buboes or drinking potions made from“unicorn horn”that swindlers sold.Others burned incense or wore flowers to purify the air.Many people turned to their faith in hope of rescue.Bands of Christians called“flagellants”walked from town to town,bloodying

49、their backs with spiked whips.They prayed this would prove to God that they were sorry for their sins and that they would be forgiven and spared.Other Europeans took a very different attitude toward their fate.With so much disease and death around them,some gave up hope of survival.They ate,drank,and partied as if the world were ending,and some were sure it was.The Plague!Level Z1
