When was the Constitution written?

The Constitution was written on September 17, 1787, during the Constitutional Convention held in Philadelphia. This date marks the conclusion of a series of debates and discussions among the delegates, who were tasked with addressing the weaknesses of the Articles of Confederation and creating a stronger federal government. The signing of the Constitution on this date represents a pivotal moment in American history, as it laid the foundation for the current system of government, establishing the principles of separation of powers, checks and balances, and federalism that continue to shape the nation today.

The other dates listed in the options are significant in American history but not related to the writing of the Constitution. July 4, 1776, marks the adoption of the Declaration of Independence, which declared the colonies' separation from British rule. May 25, 1787, is the date when the Constitutional Convention convened, but the actual document was not signed until later in September. October 1, 1787, falls after the Constitution was written and signed, as this is when the document began to be sent to the states for ratification.
