In the fourth century, thirteen conflicting colonies were transformed into a federal republic. To the colonies in America, the British imposed high taxes so that through this they could cover the debts which England had incurred in the war with the French for Canada. The challenge of British taxation has triggered Americans in their search for constitutional principles to protect their interests. The last quarter of the eighteenth century remains the best political creative period in American history, as she devoted herself in a determined group to embarking on a courageous experiment in political ideas. It was a time of victory, but also a time of tragedy - they all contributed to the formation of a new federal republic. In fact, it was a revolution of evolution brought about by a group of extraordinary people (rather than a single individual), and these factors separate it from the more violent revolutions of other countries. Indeed, the gradual significance of the American Revolution was a key factor in its lasting success. The founders (especially Washington, Jefferson, Madison, Adams in Hamilton) were not unanimous, but thus created a framework for discussing and resolving civic issues that was then the best in the most successful political experiments. The constitution was not designed to respond to political issues, but was designed as a framework, and in the future generation, political conflicts can be resolved and ideas harmonized. In my master’s thesis, I focused on the political development of the United States and highlighted, identified in descriptive key events and conflicts that affected the development of the Federal Republic.
