State ratifying conventions
State ratifying conventions are special deliberative assemblies convened by the legislatures of U.S. states to debate and vote on the ratification of the United States Constitution or proposed amendments thereto, serving as an alternative to ratification by state legislatures and enabling a more direct appeal to popular sentiment.[1][2]
Under Article VII of the Constitution, thirteen state conventions ratified the document between December 1787 and May 1789, with the approval of nine states—culminating in New Hampshire's vote on June 21, 1788—sufficient to establish the new federal government despite fierce debates between Federalists advocating centralized authority and Anti-Federalists wary of diminished state sovereignty, which ultimately prompted assurances of a Bill of Rights to secure key holdouts like Virginia and New York.[2][3]
Article V empowers Congress to designate state conventions for ratifying amendments, a mode invoked only once for the Twenty-First Amendment in 1933, which repealed Prohibition by convening delegates in thirty-eight states to circumvent entrenched legislative opposition from temperance advocates, resulting in swift and near-unanimous approvals amid widespread public demand for ending the Eighteenth Amendment's federal enforcement of alcohol prohibition.[1][4]
