Q:Were the Luddites justified in their attacks on machinery?
Turning point in history Many historians would deem the Luddite riots as unsuccessful, while many others would say that they had a huge impact on society. The Luddites changed the views of people during the Industrial Revolution. They brought the rights of the workers to the attention of England. A turning point in history is often thought of as a well-known and dramatic event that took place and completely changed the world. The riots of the Luddites are not very well-known. However, their actions led to many significant changes in the world. Politically, the actions of the Luddites brought the idea of having a society based on industrialization into the eyes of the public and open to debate. People were forced to look more closely at the positive and negative effects of having an industrial society. The machine question continues tobe unanswered today. The riots became a turning point because the flaws of the Industrial Revolution were brought to the surface and the government could no longer ignore the opinions of the working class. The Luddites stories circulated England, showing the strong resistance and bravery of the English men. People realized that if one is disciplinedand organized, he will be successful in his battles. The Luddites als brought about the ideas that technology is never neutral and some are even hurtful. For example, while the while the Spinning Jenny was beneficial to the textile industry, it also put several spinners out of business. The Luddite rebels uncovered the dark side to the Industrial Revolution!
