The first state to ratify the Constitution was Delaware on December 7, 1787
The journey to ratification was not a straightforward one. The country was governed by the Articles of Confederation, which was tailored to a newly formed nation of states acting more like independent, sovereign countries. It became clear to some of America's leaders that future stability required a stronger, more centralised government. New York's Alexander Hamilton led the call for a constitutional convention to reevaluate the nation's governing document. Some states voiced opposition to the Constitution on the grounds that it did not provide protection for rights such as freedom of speech, religion, and the press. However, the terms of the Massachusetts Compromise reached in February 1788 stipulated that amendments to that effect—what became the Bill of Rights—would be immediately proposed.

The Bill of Rights was ratified on December 15, 1791
The journey to ratification was not without its challenges. Some states voiced opposition to the Constitution on the grounds that it did not adequately protect certain rights, such as freedom of speech, religion, and the press. This led to the Massachusetts Compromise of February 1788, which stipulated that amendments—what became known as the Bill of Rights—would be immediately proposed to address these concerns.
The Bill of Rights consisted of ten amendments, introduced by Madison, that were born out of the Massachusetts Compromise. Congress adopted twelve of these amendments on September 25, 1789, and sent them to the states for ratification. Ten of these amendments were ratified on December 15, 1791, becoming the Bill of Rights and a part of the U.S. Constitution.
The ratification of the Constitution and the Bill of Rights marked a significant shift in the governance of the United States, moving away from the Articles of Confederation, which gave more power to individual states, towards a stronger, more centralized government.
