All through the history of mankind, humans thrive to make changes and create new things that will make their lives easier. Inventions change the world in drastic ways, people either benefit or are harmed by them. These inventions not only affect the lives of common people, but also the development of who holds power. The printing press, guillotine, and mustard gas all shaped the development of society and how it’s ruled. The printing press was invented by Johannes Gutenberg, a German blacksmith in the year of 1440. The printing press revolutionized how rapidly books were being printed. One of the first projects the printing press created was the Bible. It was a revolutionary creation that resulted in an increase of literate people in Europe. After reading and interpreting the Bible for themselves people began to question the Church teachings and thinking if their intentions were benevolent or malicious. At that time, indulgences were sold by the clergy to pardon people from their sins, as tickets to heaven with a steep price. Martin Luther, a Monk of the Catholic Church, saw these actions of selling indulgences as unethical. With the invention of the printing press, Luther’s 95 theses written to protest indulgences sold by the Catholic Church, were spread rapidly. People started to think for themselves rather than believing what was dictated by the people in power. Joseph-Ignace Guillotin invented the guillotine in 1789. The guillotine was designed to make executions more painless. It made executions much more effective and the room for human error was decreased with this invention. Also, prior to the invention of guillotine, criminals faced horrible punishments for their crimes. Dr. Guillotin proposed the use of this device to make the capital punishment uniform and humane for everyone as the enlightenment allowed. During this time France was tumultuous and the monarchy was using the funds for themselves. The French people were hungry, suffering high taxes and unhappy with the rulers. These circumstances lead to people revolt. The Reign of Terror was a very hard time for the people of France since as many as 40,000 people were executed. The invention of guillotine lead to mass executions and the many power changes. Mustard gas was invented by a German professor. It aimed to kill the soldiers from parallel trenches in World War I without being exposed to it themselves. The soldiers were injured by the gas that blistered their insides and bodies even with uniforms and masks. This gas was used to injure the opposing soldiers in a way that tortured them. Since, there wasn’t anywhere that the soldiers could go to get away from the mustard gas they usually were exposed to it for long periods of time in the trenches. This innovation lead to the suffering of many soldiers as the Great War went on. Also, it modified the face of warfare eternally. Countries started investing in research, on how to make and survive these chemical weapons. In conclusion, technological inventions of the printing press, guillotine, and mustard gas all helped shape the development of who holds power and move the society from monarchies to democracies. The printing press allowed ideas to be shared and spread around the world. The guillotine killed thousands of people equally. Mustard gas started the beginning of chemical weapon usage in the world. All in all, these technological developments played a major role in transforming the society that we are living in to be effortless.
