During the drafting of the constitution in the 1780s, which was such a critical time for the new nation, many new inventions were created for the benefit of the people. The dangers caused by economic crisis and the disappointment caused by the failure of revolutionary expectations of a desperate need for improvement have combined to make this decade a time of dissatisfaction and reconsideration to propose a new direction for the nation . for the nation was called the federal constitution. It had been drawn up by a group of national leaders in Philadelphia in 1787 who presented it to the general public for review. Experiments showed that unity was necessary for the survival of the nation, and the Constitutional Convention was held to see if this goal could be achieved. The Constitution amounted to an entirely new set of rules for organizing national government and indicates the intensity of the political thinking of the time as well as the extent of change since 1776. The proposed national framework required a strong central government that would have authoritative on the national government. States. At the same time, the draft Constitution also involved central participation of the people in deciding whether to accept the new plan through a process called ratification. The Philadelphia Constitutional Conventions brought together all the major leaders of the United States to meet and develop economic policy, in the same way that competing national policies often ended in disagreement. Although there were many difficult times, it took a strong new nation for the people. , many prominent leaders still pursued inventions that benefited themselves and the people. In 1784, Benjamin Franklin developed bifocal glasses. It was... middle of paper... in London and it was read aloud. Then they prepared the letters to be printed in the newspaper. The typewriter had not yet been invented at that time, so letters were written by hand. Gutenberg had already invented the printing press a few centuries before, so the Royal Society was able to use pretty type to insert the letters. During the 19th century and before, many people were inventing things at the same time and because communication was not instantaneous, news traveled slowly, and sometimes multiple people were inventing the same things, but their creativity. As in drafting a new nation, through many efforts and disappointments, it will take time, trial and error, the death of so many people for the new constitution to be developed, and all the inventions to work wonderfully the first time. benefit “the people”.
