In what year was the Constitution ratified?

The Constitution was ratified in 1788. This marked the culmination of the efforts to create a new framework of government following the weaknesses of the Articles of Confederation. The ratification process began when delegates from the Constitutional Convention signed the document on September 17, 1787, but it required approval from nine out of the thirteen states to become effective. By June 21, 1788, the necessary states ratified it, allowing the Constitution to officially replace the Articles of Confederation.

The year 1788 is significant as it represents the time when the new system of government, structured around the principles of federalism and the separation of powers, was set to be implemented, leading to the establishment of the United States as we know it today.
