In what year was the Constitution written?

The Constitution of the United States was written in 1787 during the Constitutional Convention held in Philadelphia. This pivotal event brought together delegates from various states to address the inadequacies of the Articles of Confederation and ultimately led to the drafting of a new governing document.

The year 1785 is significant for various events in early American history, but it predates the Constitution. The year 1791 is important as it marks the ratification of the Bill of Rights, the first ten amendments to the Constitution, which protected individual liberties. The year 1793 does not have a direct association with the writing of the Constitution, although other important events in U.S. history occurred around that time.

Thus, 1787 stands out as the correct answer because it directly relates to the time when the foundational document of the United States was created.
