Tudor Revolution in Henry Viii

Tudor Revolution in Henry Viii After the Tudor dynasty English government and kingship was never the same. The way the kings power switched from a Medieval system of hierarchy his control over his land was limited, to rule he needed support of the nobility and church and his parliament ineffective to an oligarchical government where the kings influenced penetrated his land, his nobility and within the government the power of the nobility shrank and the church became a secular concern. Government modernised through the centralisation of power and royal supremacy would rule. Parliaments importance would be re-invented and reforms to administration, law and justice, sovereignty and church power could be described as a revolution in government which under Henry VIIIs reformation of the church brought new opportunities for the consolidating of royal power. Cromwell reforms in the 1530s appear to be the turning point  [1]  . Although to say royal supremacy was an achievement, to say it occurred within the space of o ne decade seems restrictive and to say one man reformed a national government seems to simplistic, but looking at Henrys reign post-Cromwell Henry seemed more interested in his love life and war than gaining further reforms. Also Edward VI and Mary Is rules brought the return of factionalism, the return of power to the nobility and a decline in an effective government and Elizabeth, however, may have ruled stronger than her siblings the crown was never quite the same after Henry VIII died  [2]  , considering the damaged inflicted and the rising threat of the gentry and Puritanism which restricted her abilities to passstatueo prove that if there was a Tudor revolution, it must have happened under Cromwell. However, were Henrys and Cromwells reforms really a revolutionary? Hoak claims the rise of royal supremacy was emittable  [3]  but Elton, the theorist who invented the concept of the Tudor revolution believes although ideas may have been present, he remained the man who tur ned ideas into reality  [4]  , but surely this is admits if not him then someone else would have done it? Throughout this essay I will examine the areas of reforms instigated under Cromwell and Henry VIII as previous mentioned and examine whether they brought revolutionary change or were an obvious step towards secularisation. If there was a revolution in government it is necessary to look at the effects of the reformation on government control as the centralisation of the church was the first real break from Medieval tradition and ignited the want for royal supremacy. The church was the centre of life for the English population of all social rankings and therefore was the real center of power and whos alignments rested not with the king but with a foreigner power, the pope. The church had a separate court for which the kings power was exult  [5]  and bishops like Worsley had direct influence in the running of the government, and its law system and corruption within the church was greater than in government as Skeleton notes people did not come to court because there was better profit in attending cardinals rival court  [6]  . The church was a rival government within a government, it seems logical that to bring it under state control and historically, very much like the actions of Constantine the G reat, kingship has been restored to its full inheritance and endowed with the authority of the early Christian emperors  [7]  , however, although ironically it was a step back to go forward, how is learning from history revolutionary? The fact the backlash received from the nobility and populas was due to the feeling the church had too much land and power and disdain for the influence that a foreign body had within England  [8]  , suggest it was not such a radical idea as some made out to be, suggesting that others had contemplated it before. From this we can see a reformation of the church also caused a reformation of politics, but not necessarily a revolution. The break with the church inspired the idea of sovereignty and of commonwealth but where these new concepts? The idea of sovereignty of a unified self-governing free state, away from the authority of any sovereign potentates  [9]  appears certainly as a revolutionary in the history of English ruler-ship and as Elton suggests would have been the main driving forced spurring revolutionary change  [10]  as sovereignty consolidated Henrys land and government under Henrys control. Both Henry and Cromwell believed the House of Commons had to represent the whole nation  [11]  for the first time the entire nation would be under Westminsters control. The eliminated other small rivals courts those in Buckinghamshire and Sheffield  [12]  and brought Wales and northern counties under the kings rule for the first time, i.e. places like Durham  [13]  through Cromwell uses of councils and the influence of parliament in all the kingdom, i.e. even Calias had two seats in parliament  [14]  . Of course if under the control of parliament laws would be easier to enforce, regulate and to put the most loyal in control. On the other hand, this idea perhaps again is nothing but new, as Edward III during the Hundred Wars Year had created a national nobility and joined the country against the free of the French  [15]  , Henry and Cromwell likewise could have used the situation of the reformation to unite England using the same mentality against the Catholic church. The shifting use of power and effectiveness of parliament, however, does not seemed copied from the pages of history. Parliament Elton argues Henry VIIIs turning to parliament proved his supreme political genius; that his deliberate decision to take the nation â€Å"into partnership‚ was the most momentous step in the rise of parliament  [16]  , for Elton sovereignty created a duty and purpose for Parliament, however, it it seems Henry used parliament as a propaganda tool to promote the acceptance of change and show the link between the king and people  [17]  as Henrys supremacy was dependent on divine appointment and not parliament. However, from an administrative point of view Henry hereafter had a greater control over his kingdom, but parliament did not restrict Henrys decisions. This seems to point towards less of a governmental revolution and more towards a despotic government, historians like Gardiner have alleged Cromwell used his power more as an autocratic weapon  [18]  and Pollard portrays Cromwell especially like some Machveillian monster  [19]  , which both suggest the real intentions of Henry and Cromwells government. However, perhaps this could be interpreted as the Tudor revolution, considering other historic despotic governments, like Communist Russia, although a modern comparison, it was still a revolution of politics and considering politically, socially and economically almost resembled a Medieval state, it does become a fair comparison. Regardless of this parliament became an effective organ of government and brought reforms to the law and juridical system, the church and administration. Cromwells administration produced the largest body of statues seen before the 19th Century  [20]  , most centred on the church and many laws were to do with kings affairs i.e. Henry VIII passed 81 bills in his interest, though considering he was trying to legitimise a marriage to Ann Boleyn, its hardly surprising, but none the less a groundbreaking swift from Medieval politics. However, Roskel believes parliament developed from its Medieval roots and that by a natural process (the need for secularisation perhaps) and not the product of a Tudor revolution as the only change was a new theory of parliament and in the process drastically altered the practice  [21]  . The perfect example of this is the Privy council and demonstrates the need to remove the problems of factions and power which the nobility held. The Privy council had existed before Henry and Cromwell but the way it was used differed greater. The council would be an important link between parliament and the king and power came down only to those the king choose and old knightly elements were reduced to a few significant roles. The number of members decreased and meant those in power could not and made it easier to pass laws and to avoid factions, i.e. Henry VIIs council of 1472 included 72 men, whereas Henrys first had only 19  [22]  and members now had to have worked within the government before they could be in the council  [23]  , therefore this new system would exclude the majority of the nobility who might only serve their own interests. This can certainly be viewed as a revolutionary change, like the church the nobility was another thorn in the side of many English kings, although the council cut out the use of the nobility it was not a political instrument for assuaging opposition  [24]  , concessions still had to be made and therefore could not be completely revolutionary as the nobility were key important in keeping regional control. The most significant change perhaps was that the council could pass laws by proclamation and unlike its European counterparts in Spain and France who could only advise the king  [25]  , whereas the English privy council was able to influence and intervene the kings decisions, this reflects a comprising relationship where although Henry had royal supremacy he did not have a complete free reign over policy which shows policy being built on the existing governments foundations which lead to the improvement of the common law and the function of parliament  [26]  , but were these improvements revolutionary? Henrys reign was built on law and reforms to the common law and the judicial system from the 1530s onward they began to obey statue in a way they had never done before  [27]  , for the first time on a national level the process by which parliament made laws and court administrated them was enforced throughout the land. From 1532 for the first time the government conceived legalisation became the new focus in the houses, this was something which Elton says no one ever dreamt of establishing  [28]  changes in the law through Parliament, this was truly revolutionary. This shift towards the creating and then enforcing on law was something which had not happened under Medieval governments. Henry had control over both religious and regional courts, he had the ability to appoint judges and juries and unlike any other point made it seems a decision that was not emittable or the result of natural change as there had been no demand for a stricter enforcement of the law. Changes within the administration system also could be described as revolutionary. Administration benefited hugely from Cromwells policies and the outcome of the reformation. The change of law lands over church properties brought plenty of money into the The crowns new revenue courts showed the move towards the elimination of purely personal in favour of lasting bureaucratic control  [29]  . Henry said wherein we as head and you members are conjured and knit together into one body of politic  [30]   basically organic view of state in harmony and mutually dependent on its subjects. Although idea around since Dudleys Tree of Commonwealth (1509) and practised by Henry VII though Cromwell brought a renewed vigour in the practice.

A Passage from Hamlet :: essays papers

A Passage from Hamlet Hamlet is probably the best known and most popular play of William Shakespeare, and it is natural for any person to question what makes Hamlet a great tragedy and why it receives such praises. The answer is in fact simple; it effectively arouses pity and fear in the audiences’ mind. The audience feels pity when they see a noble character experiencing a regrettable downfall because of his innate tragic flaw, and they fear that the same thing might happen to them. Hamlet’s speech (III, iv, 139-180) contributes to producing this feeling of pity and fear. First it explains the thought with particular emotional effectiveness. Second it conveys Hamlet’s character, both virtue and tragic fear. Lastly, it marks the beginning of the tragic discovery and Hamlet’s downfall, answering the question â€Å"why does Hamlet delay?† Observing the beginning of Hamlet’s downfall and tragic discovery in this passage, which happens despite his many virtues, maximizes the pity and fear at the same time. The first contribution is that this passage conveys Hamlet’s thoughts with poetic and emotional effectiveness. Hamlet denies his madness and urges Gertrude not to make his madness an excuse for her faults. He asserts that excuses would only cover the superficial faults and the soul would be corrupted deep within. He further asks Gertrude not to commit any more sins that make past faults even worse and to confess herself to heaven. After all, Hamlet sarcastically begs her pardon for his reproach. Hamlet explains that during the extremely rotten time, Hamlet, who is good and of virtue, must beg pardon to and get permission from Gertrude, who represents vice by committing many sins, to do good things such as urging her to repent. As a method for salvation, Hamlet asks her not to go to Claudius’ bed. Then he apologizes for the death of Polonius and admits his own fault. However, he insists that Polonius and he both are punished because God has made him the agent to punish Polonius with him and him with Polonius. He takes the responsibility, and explains Gertrude that he is cruel only to be kind to her and warns that worse things are yet to come. Through out the passage, imageries are used to add poetic emotion to Hamlet’s thought. One example is â€Å"unction† in Hamlet’s speech â€Å"Lay not that flattering unction to your soul†¦It will but skin and film the ulcerous place whiles rank corruption, mining all within, infects unseen.

College Savings Essay

Why is it important to go to college? I believe the answer is crystal clear. Attending college provides me with an opportunity for a better future. The economy now is not the same as it was in the past. Those who graduate high school are finding it extremely difficult to obtain high-paying jobs. The United States has been reformed into an economy dependent on knowledge. Graduating college provides the graduate with more desirable opportunities and options. It is a proven fact that having a college degree increases your chances of receiving a high-paying job; and isn’t that what we strive to achieve in our lives? The reason I wake up everyday and attend school is to one day have a high-paying job, that will make all the years of education worth it. However, though a college education is immensely important, it carries a heavy price tag. Unfortunately, the cost of tuition goes up every year, preventing many teens from attending college. I myself do not allow that unfortunate fac t to discourage from obtaining a college education. I am aware of the numerous available financial aid options. Though I am only in middle school and still have a couple more years before I can start college. I believe that I should be preparing myself for the future years ahead considering the fact that they are critical in my success. I often find myself searching the web for colleges and imagining myself attending those colleges in the future. But unfortunately, daydreaming is not going to get me anywhere. Once I snap out of it, I began to search for strategies that will benefit me in my quest to attend college. In my opinion, it is critical to form a strategy early on in the game. The sooner the better. The amount of money needed to attend college is great, so saving money early on is the best way to go. I have become aware that scholarships and financial aid do not pay for everything! Though they offer a tremendous amount of help, I will have to pay as well. That is why starting early is crucial. Of course, I will not be able to accomplish my goal without the help of my parents. They are the ones who will guide me and offer the necessary assistance that I desperately need. Making my parents aware of my strategy is the second step and probably the most important. Considering I am still a minor, their help is essential. The chances of receiving a scholarship or financial aid is not guaranteed! I cannot afford to place all my hope in the idea of a scholarship or grant and neither can my parents. We have to think ahead and prepare for the challenges that I will have to face. It is important for my parents and I to find out as much as we can about financial aid and the necessary requirements we have to meet to be able to receive the aid. Though the price of education is being raised, so is the amount of financial aid I can receive. The financial aid package that I will be given to me is determined by the college that I wish to attend. That is why I’m already searching online for colleges that I picture myself attending, and familiarizing myself with their criteria for incoming students. Receiving financial aid or any type of support is ultimately up to me. Scholarships are not given to everybody. I have to earn it. In order to improve my chances of receiving a scholarship, I have tried absolute hardest to obtain excellent grades. Most of my friends believe that middle school holds little importance. I disagree. It’s vital to put your maximum effort in your studies from the get-go. When I apply to colleges, I want them to realize that I’m serious about graduating and having a successful future. I cannot afford to begin to take college seriously in high school, because it may be too late. If I start preparing myself and researching about college early on, I will be ready and prepared when my high school years arrive. Which surprisngly are right around the corner. Forming a saving strategy is essential in my plan to attend college. There are various companies and websites that offer me the help and guidance to form my strategy. For example, the 529 Plan. The 529 plan is a tax-advantaged investment plan built to encouraging f uture college attendees to save for a college education. But these programs are not the only way to go. My school counselor and teachers also offer their expertise on the topic of college. My school’s faculty, for a fact, has my best interest at heart. They are constantly giving me advice on high school and what lies ahead. Now that I am in my eighth grade year, the topic of high school has been popping up more frequently in our discussions. I am still young and do not know all there is to know about college and the best way to start saving for it. So, I rely on the help of my teachers, counselor and of course, my parents. With their advice and support, I will be able to form a strategy that will help me save money for college. It is obvious that I cannot depend on their help alone. It is I who has to take their advice and put it motion. For example, I am allowed to work part-time at the age of 14. I know that it is extremely difficult to balance work and school so, I have decided to begin working during the summer. With of course m y parents consent. Having an income will help me tremendously. College costs a lot of money and considering the fact that my parents don’t have the biggest income, I’m grateful for the fact that I will be able to work and offer my parents a lending hand on my savings for college. Neither of my parents have a college education. I do not judge them because I know the challenges they have encountered, for I have witnessed them myself. My entire family was born in Cuba where a college education was difficult to achieve. When we first arrived in the United States, my parents found it extremely difficult to get job. This caused my family to go through many struggles. Struggles that we are currently experiencing today. Witnessing these struggles have given me the determination to have a successful future. I do not wish for my future children to go through what I have gone through. My parents understand this. Not only do they understand it, they encourage it. They are constantly referring to me as their ‘better future’. It is clear that they want me to succeed. They don’t want me to be constantly worrying about not being able to pay the bills or rent. They want my future to be worry free. They understand how important college is and have already began taking the necessary steps to guarantee that I attend. Having my parents support is essential for I do not think I would be able to do it on my own. Though they are not familiar with steps that need to be taken to get into college, they are trying their best to help me achieve my goal in any way that is necessary. Most people already know why college is important; it opens numerous doors and provides many opportunities and advantages once you have graduated. It has been proven that people with a college education earn nearly twice as much than those who only have a high school diploma in their pocket. You go to school to get good job, to earn money and have a successful f uture. A college education guarantees that. A college education increases my chances of living the life I have always wanted. The life my parents wish for me. In the United States today, having a college education is extremely important. Without it, you will most likely get nowhere. I would know. My parents do not have a college education. I have watched them suffer financially and the thought of me having through go through their struggles terrifies me. I do not want to live in constant stress over late payments or having no money to buy food for my kids. I know how difficult it will be to attend college. I know that I will have to make sacrifices to guarantee my future. But I am willing to make those sacrifices because I only the consequences that I will face if I don’t. Most people will not understand why I have decided to start saving up for college or even thinking about college so early on. But I have my reasons. College is more important to me than people realize. It’s the key to a successful future. My successful future!
