Rats and fleas off the hook: humans passed Black Death to each other | News | The Week UK - 1 views

  • The Bubonic Plague of 1348 was actually a pneumonic plague, say scientists studying skeletons dug up in London
  • RATS and fleas have been unfairly implicated in the spread of the Black Death, according to scientists studying the remains of Londoners who died in the 14th century.
  • scientists now believe that a death rate of such magnitude would only have been possible if the plague had been airborne.

BBC News - 'Gerbils replace rats' as main cause of Black Death - 3 views

  • If we're right, we'll have to rewrite that part of history."
  • The Black Death, which originated in Asia, arrived in Europe in 1347 and caused one of the deadliest outbreaks in human history.
  • It had been thought that black rats were responsible for allowing the plague to establish in Europe, with new outbreaks occurring when fleas jumped from infected rodents to humans.
  • ...5 more annotations...
  • They compared tree-ring records from Europe with 7,711 historical plague outbreaks to see if the weather conditions would have been optimum for a rat-driven outbreak.
  • "We show that wherever there were good conditions for gerbils and fleas in central Asia, some years later the bacteria shows up in harbour cities in Europe and then spreads across the continent," Prof Stenseth said. He said that a wet spring followed by a warm summer would cause gerbil numbers to boom.
  • And because this was a period when trade between the East and West was at a peak, the plague was most likely brought to Europe along the silk road, Prof Stenseth explained.
  • "Suddenly we could sort out a problem. Why did we have these waves of plagues in Europe?
  • The team now plans to analyse plague bacteria DNA taken from ancient skeletons across Europe. If the genetic material shows a large amount of variation, it would suggest the team's theory is correct.

    This article calls into question how the plague was moved from Asia to Europe..not fleas, but Gerbils:)

Medieval "Black Death" Was Airborne, Scientists Say - History in the Headlines - 0 views

  • w, analysis of skeletal remains found by construction workers digging railway tunnels in central London has led scientists to a stunning new conclusion: The Black Death was not transmitted through flea bites at all, but was an airborne plague spread through the coughs, sneezes and breath of infected human victims.

TED Cast Study BUBONIC - 1 views

  • Between 1339 and 1351 AD, a pandemic of plague traveled from China to Europe, known in Western history as The Black Death
  • The Black Death was actually a combination of three different types of plague: bubonic, pneumonic, and septicaemic, with bubonic being the most common
  • The initial symptom is a blackish pustule forming over the point of the bite, followed by swollen lymph nodes near that bite.

  • bruise-like purple blotches, called buboes, on the victim's skin. It is from this word, buboe, that the bubonic plague takes its name. The hemorrhaging causes an intoxication of the nervous system, which produces neurological and psychological disorders, including insomnia, delirium, and stupor
  • Septicaemic plague is, like the bubonic plague, carried by insects. Its distinguishing feature is its rapidity - death occurs within a day of infection, even before buboes have had time to form. This form of the plague is the rarest rare, but is almost always fatal
  • victims suffer a sharp drop in body temperature, which is followed by sever coughing and discharge of a bloody sputum
  • airborne transmission.
  • None of these plagues are native to Europe.
  • bacteria normally resides in Central Asia, Yunan China, Arabia, East Africa, and limited areas of Iran and Libya.
  • Their spread to Europe from these areas has always been through global commerce - trade which carried with it plague- bearing rats and fleas.
  • From China, the plague is known to have been carried along the Silk Road into Central Asia, where there are records of outbreaks in 1339.

How Feudalism Works - 0 views

  • Mind Your Manors   In the days of decentralized government, a fief was like its own mini country that produced pretty much everything that was needed from food to weapons to tools. At the heart of a lord's fief was the manor-large estates. The manor was where the lord's family, servants, and his knights lived. At first they began as large houses, but over the years became full castles as walls, towers, and moats were added for protection. Manors were always in the country and surrounded by farmland and woods. Some of the wealthier lords even had more than one manor.   A manor was the center of the community. Not only did it serve as a place for peasants to run to in times of war, but was the political center as well. When he wasn't out fighting for his Lord, the lord of a fief would act as a judge in settling disputes. He also appointed officials who would collect taxes and rent from the peasants and townspeople. Large manors had their own churches complete with their own clergy, as well as a marketplace where locals could buy and sell goods. At any time one time, hundreds of people from priests, knights, squires, entertainers, merchants, peasants, and visiting nobles would head to the manor.   For the Lady of the manor her day was spent overseeing servants & caring for the children. When her husband was away (or killed in battle) the Lady of the manor assumed the same roles her husband did, appointing officials and acting as judge. In the early Middle Ages a woman owning property was not all that uncommon.
  • Living in a castle might sound romantic but it's not all that it was cracked up to be. Medieval manors were built of wood and stone and built on a large scale. Glass was rare and extremely expensive so windows often were either left open or covered with cloth during the winter. The only means of heating a manor was the fireplace. Each major room had its own. The Great Room, which as its name implies was the center of manor life.  The Great Room was heated and lit by an enormous fireplace, big enough to stand in. The Great Room was where all of the eating, drinking, debating, politicking, and merry making and other business was conducted. Speaking of doing business, how did medieval people use the bathroom? All manor houses had privies either outside or inside the castle. The ones inside were nothing more than a seat that emptied directly into the moat. ​ To modern observers manors would have been filthy places. Fleas were common and the smell of hundreds of unwashed people (who often only bathed once a week) would have pervaded. Rats and mice also would have been running around as food was thrown directly on the floor during meal times. At night the servants swept the floor and rushes (dried river reeds) would be spread on the floor and all minor visitors and knights would bed down. The manor was often dark, cold, and smoky. To liven things up a bit, tapestries would be commissioned to decorate the walls.

The Black Death of 1348 to 1350 - 4 views

      Mr.Holman you said that the people had some fever and then died right?
  • "The first signs of the plague were lumps in the groin or armpits. After this, livid black spots appeared on the arms and thighs and other parts of the body. Few recovered. Almost all died within three days, usually without any fever."
  • The Black Death had a huge impact on society. Fields went unploughed as the men who usually did this were victims of the disease. Harvests would not have been brought in as the manpower did not exist. Animals would have been lost as the people in a village would not have been around to tend them.

  • Those who survived the Black Death believed that there was something special about them – almost as if God had protected them. Therefore, they took the opportunity offered by the disease to improve their lifestyle.
  • Peasants could demand higher wages as they knew that a lord was desperate to get in his harvest.
  • To curb peasants roaming around the countryside looking for better pay, the government introduced the Statute of Labourers in 1351 that stated: No peasants could be paid more than the wages paid in 1346. No lord or master should offer more wages than paid in 1346. No peasants could leave the village they belonged to.
  • Though some peasants decided to ignore the statute, many knew that disobedience would lead to serious punishment. This created great anger amongst the peasants which was to boil over in 1381 with the Peasants Revolt. Hence, it can be argued that the Black Death was to lead to the Peasants Revolt.
