What aspects of information should you include Disscussion Background Process Impact The Black Death The Black Death The Black Death (also known as the Pestilence, the Great Mortality or the Plague) was a bubonic(腹股沟腺炎的) plague pandemic occurring in Afro-Eurasia from 1346 to 1353. It is the most fatal pandemic recorded in human history, causing the death of 75–200 million people in Eurasia and North Africa, peaking in Europe from 1347 to 1351. Bubonic plague is caused by the bacterium Yersinia pestis(鼠疫杆菌) spread by fleas, but it can also take a secondary form where it is spread person-to-person contact via aerosols(气溶胶)causing septicaemic(败血症) or pneumonic(肺炎的) plagues. The Black Death was the second great natural disaster to strike Europe during the Late Middle Ages (the first one being the Great Famine of 1315–1317) and is estimated to have killed 30 percent to 60 percent of the European population, as well as about one-third of the population of the Middle East. The plague might have reduced the world population from 475 million to 350–375 million in the 14th century. There were further outbreaks throughout the Late Middle Ages and, with other contributing factors (the Crisis of the Late Middle Ages), the European population did not regain its level in 1300 until 1500. Outbreaks of the plague recurred around the world until the early 19th century. The Black Death
