In what year was the Constitution written?

The Constitution of the United States was written in 1787 during the Constitutional Convention that took place in Philadelphia. This gathering aimed to address the weaknesses of the Articles of Confederation and resulted in the drafting of the Constitution, which established the framework for the federal government and outlined the separation of powers among its branches. The Convention took place from May to September 1787, and the final version was signed on September 17 of that year.

The other years listed are significant in their own right but pertain to different milestones in American history. For instance, 1785 saw the Articles of Confederation already in place, while 1789 marks the year the Constitution was officially ratified and the new government began functioning. Finally, 1791 is notable for the ratification of the Bill of Rights, the first ten amendments to the Constitution, which provided important protections for individual liberties.
