On August 18, 1920, the Nineteenth Amendment to the U.S. Constitution was ratified. The amendment legalized women’s suffrage in the United States. Susan B. Anthony, the author of the amendment, did not live to see Congressional passage or ratification of her proposal. Her death in 1906 followed a long career as a suffragist and general reformer. She wrote a women’s suffrage amendment in 1878 and persuaded a sympathetic senator from California, Aaron Augustus Sargent, to introduce the measure in Congress that year. Although Congress failed to act on the resolution, it became a focal point for suffragist activity and public attention. Anthony’s resolution, also known as the “Anthony Amendment,” was reintroduced in every session of Congress with its wording unchanged until its passage forty-one years later, in 1919. Final acceptance of the amendment can be attributed primarily to the plan introduced by Carrie Chapman Catt, president of the National American Woman Suffrage Association (NAWSA), at that organization’s annual meeting in 1916 at Atlantic City, New Jersey. She called for cooperation across the suffragists’ spectrum and the mobilization of state and local organizations for the cause. The plan also suggested the targeting of unsympathetic legislators at all levels. By 1918 she had secured the endorsement of President Woodrow Wilson. Although it required another eighteen months of diligence, the goal was accomplished, and women across the United States voted in the presidential election of 1920.
