What is the significance of June 21, 1788, in relation to the Constitution?

June 21, 1788, holds significance in relation to the Constitution as it marks the date when New Hampshire ratified the U.S. Constitution, becoming the ninth state to do so. This ratification is crucial because the Constitution stipulates that it would take effect once nine states had ratified it. With New Hampshire’s approval, the Constitution reached the necessary threshold to be enacted, leading to the formation of a new federal government under its framework. This pivotal moment underscores the collaborative effort of the states in establishing a stronger national government, moving beyond the limitations of the Articles of Confederation, which had previously governed the United States.
