In which year was the Constitution of the United States created?

The Constitution of the United States was created in 1787 during the Philadelphia Convention, where delegates from the states gathered to address the weaknesses of the Articles of Confederation. This gathering resulted in the drafting of the Constitution, which established the framework for the federal government and its relationship with the states and citizens.

The year 1789 is significant because it marks the year when the Constitution was ratified and went into effect, as well as the year George Washington was inaugurated as the first President. The year 1791 is notable for the ratification of the Bill of Rights, the first ten amendments to the Constitution, which guarantee individual liberties. The year 1783 refers to the end of the American Revolutionary War, when the Treaty of Paris was signed, but it is not related to the creation of the Constitution. Therefore, the correct answer is 1787, as that is when the document was initially drafted.
