The Ratification Period refers to the time frame following the Constitutional Convention of 1787 during which the newly drafted United States Constitution was submitted to the states for approval. This period, lasting from September 1787 to June 1788, was marked by intense debates and discussions among Federalists and Anti-Federalists regarding the merits and potential drawbacks of the Constitution. It laid the foundation for the establishment of a stronger federal government and highlighted the divisions in American society over governance and individual rights.
