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 event was crucial as delegates from various states convened to address the weaknesses of the Articles of Confederation and create a stronger federal government. The year 1787 is significant because it marks the beginning of a new framework for governance that included a system of checks and balances, separation of powers, and federalism. After being drafted, the Constitution was then sent to the states for ratification, which was completed in 1788. Thus, the choice of 1787 as the year the Constitution was written is correct, as it reflects the historical context in which this foundational document was created.
