The National American association holds its convention in St. Louis, where Catt rallies to transform the association into the League of Women Voters. For a third time, the House votes to enfranchise women. The Senate finally passes the Nineteenth Amendment, and suffragists begin their ratification campaign. In the case of Hawk vs. Smith, anti-suffragists file suit against the Ohio legislature, but the Supreme Court upholds the constitutionality of Ohio's ratification process. Despite the political subversion of anti-suffragists, particularly in Tennessee, three quarters of state legislatures ratify the Nineteenth Amendment on 26 August.
American women win full voting rights.
