The Bubonic Plague (Black Death) Free Essays

The pandemic of the bubonic plague swept across Europe in 1347 and spread to England in 1348. It is known today as the Black Death. During these years, the plague affected the lives of people all across England and killed over half of England’s population. We will write a custom essay sample on The Bubonic Plague (Black Death) or any similar topic only for you Order Now It’s impact was enormous, not only because of the rapid decrease in the population but because of the pessimism, fear and suspicion. â€Å"Plague is a deadly infectious disease that is caused by the enterobacteria, Yersinia pestis. Primarily carried by rodents (most notably rats) and spread to humans via fleas† – Wikipedia The plague caused a huge decline in England’s population. It killed over 5 million people (70% of the population) Some of the first symptoms were vomiting, giddiness, headaches, shivering, tongue turns white, and intolerance to light. Some of the later symptoms are pains in the joints, breaking blood vessels, internal bleeding, and skin turning black (the result of the dried blood from internal bleeding) During the plague peasants left their jobs because they were afraid they would get the Black Death and die. Many also left for other villages to find new jobs, better wages and conditions. Since there wasn’t many farmers to make food, the price of food went up during the plague. There were not enough people to look after animals and crops, so they died too. Some people in urban areas died, not from Bubonic Plague but from starvation. Some villages became completely abandoned because of the villagers evacuating. Because of the Black Plague villages faced starvation. Town and cities faced food shortages as the villages that surrounded them could not provide them with enough food. A big consequence of the Black Death was inflation – the price of food went up creating more labour for the poor. In some parts of England, food prices went up by four times. Many Lords were short of desperately needed labour for the land that they owned. After the Black Death, Lords encouraged peasant to leave their villages and come work for them. When peasants did this, the Lord refused to let them return to their original village. The peasants started demanding higher wages as they knew that the Lord was desperate to get his harvest. The Black Death brought great depression that was felt through out England and affected the lives of millions, it is one of the most lethal disease out breaks in history.

Things Fall Apart By Achebe Essays - African Writers Series

Things Fall Apart By Achebe All stories have a protagonist, which is a person or place that the story focuses on and gives special traits. In Chinua Achebe's Things Fall Apart , the story follows the life and actions of Okonkwo. As the story progresses, the reader becomes most intimate and learns a great deal about Okonkwo. Okonkwo acts as the protagonist in Things Fall Apart because he appears to be a very strict father and husband, by showing loyalty to his village, and by working hard. The first reason that Okonkwo acts as the protagonist is because he is a strict father and husband. In the Nigerian culture it is a custom for a man to be strict and harsh in the ruling of his family. For example, in the story Okonkwo says, "I will not have a son who cannot hold up his head in the gathering of the clan. I would sooner strangle him with my own hands." This is showing that Okonkwo is so strict that he would threaten his own son, maybe even strangle him rather then let him grow up weak. Another reason that Okonkwo is the protagonist inThings Fall Apart is because he shows loyalty towards his village. He fights skillfully and bravely in order to defend his village. When Okonkwo has his fill of the invading British, he risks his life by killing the head messenger, who is attempting to brake up a traditional Umuofian meeting. This shows that he has loyalty for his village by sacrificing himself and killing one of the messengers but letting the rest of them go so that Umuofia would not go to war. Okonkwo is also a very hard and dedicated worker. For example, following the harvest, "The only work that men did at this time was covering the walls of their compound with new palm fronds. And Okonkwo had already done that. He had finished it on the very day the locusts came." This makes it evident that Okonkwo works hard and does not procrastinate . In Things Fall Apart, Achebe excellently portrays a typical African village during the British invasion. With the character Okonkwo, he expresses the feelings of many Africans of the time period. It is for this reason that the book Things Fall Apart is a modern classic.

Why People Fear Old Age essays

Why People Fear Old Age essays In todays society every one wants to look young and attractive. We want to be able to stay independent, and in touch with modern times. Old age has become a social problem in our time. The reality of getting older is manifested through stereotypes and myths. Common stereotypes of aging view the old as out to the pasture, over the hill, and all washed up. We want to be able to stay youthful and enjoy life to its fullest. No matter what lengths we go to, to stay young, there will always be that fear in the back of our minds of getting old. Because of this we often look at aging as a negative perception. We fear the mental and physical decline. The thought of not remembering our past or even friends and families is scary, what is there to like about forget all the wonderful memories that took us so long to accumulate. And then theres the fear of physical decline, knowing that we risk the chance of not being as youthful as we would like to be. Missing out on all the fun of playing with the grandchildren, taking long walks at night or even those bike rides that we once enjoyed. The thought loneliness, being unwanted, or becoming a burden and dependent upon our friends and family members is another reason we fear getting old. It seems like when we get older our friends tend to diminish and our interests seem to clash with the younger generation, so they stop coming around as much. Then theres the thought of having to rely on other people to help us in our daily activities. The last thing we want is for someone to have to take care of us, and loosing our independence. No more being able to jump in the car and go to the store or friends houses. Finally theres the thought of disease and death, which people state are their biggest fears or old age.

UK Music Retailers Assignment Example | Topics and Well Written Essays - 2500 words

UK Music Retailers - Assignment Example Businesses operating in any industry are bound to experience changing fortunes in so far as trade is concerned. There are several forces that play in the economy thus influencing the fate of each of the entities in a given sector. With this in mind, it is the sole responsibility for individual business organizations to examine factors within their environment and identify the interventions to keep it competitive. I further use interaction matrix to analyze how the business has changed over time. Finally, I conclude by comparing two players in this music sector and offer some appropriate recommendations. Just like in any other economy of the world, the UK economy also suffers from quite a number of challenges. Being an important component of the economy, UK retailers have not been spared from the difficult moments that occasionally characterize the economy. Therefore, some traditional UK retailers such as music retailers who deal with the selling of music CD and VCD have been critically affected. In the past few years, some famous music retailers went bankrupt one after another. Cases in point include the Towers, KPS, and Virgin. Whilst some of the aforementioned retailers were troubled by the market changes, the likes of Find-CD, which is an online music company, were flourishing (Traynor, 2013). According to the findings of Traynor (2013) in his research, nearly 140 music retailers are prone to the perilous economic period in the near future. A case in point is the HMV music retailer. HMV is credited for having been one of the longest-serving players in the music industry with a history of music retailing of approximately 91 years. It deals with the sale of CDs/DVDs containing music, movies, or video games.
