What year was the U.S. Constitution ratified?

The U.S. Constitution was ratified in 1787, which is a pivotal year in American history. This event followed the Constitutional Convention held in Philadelphia, where delegates convened to address the weaknesses of the Articles of Confederation. After much debate and discussion, the Constitution was finalized and presented to the states for ratification. By June 1788, enough states had ratified it for the Constitution to become effective, but the formal signing took place in 1787. This document established the framework of the federal government and is considered the supreme law of the land, outlining the separation of powers, checks and balances, and the rights of citizens. This context highlights the significance of 1787 in the establishment of a stable and lasting government for the United States.
