The Nineteenth Amendment (Amendment XIX) to the United States Constitution prohibits the United States and its states from denying the right to vote to citizens of the United States on the basis of sex, in effect recognizing the right of women to vote. The amendment was the culmination of a decades-long movement for women's suffrage in the United States, at both the state and national levels, and was part of the worldwide movement towards women's suffrage and part of the wider women's rights movement. The first women's suffrage amendment was introduced in Congress in 1878. However, a suffrage amendment did not pass the House of Representatives until May 21, 1919, which was quickly followed by the Senate, on June 4, 1919. It was then submitted to the states for ratification, achieving the requisite 36 ratifications to secure adoption, and thereby went into effect, on August 18, 1920. The Nineteenth Amendment's adoption was certified on August 26, 1920.
Before 1776, women had a vote in several of the colonies in what would become the United States, but by 1807 every state constitution had denied women even limited suffrage. Organizations supporting women's rights became more active in the mid-19th century and, in 1848, the Seneca Falls convention adopted the Declaration of Sentiments, which called for equality between the sexes and included a resolution urging women to secure the vote. Pro-suffrage organizations used a variety of tactics including legal arguments that relied on existing amendments. After those arguments were struck down by the U.S. Supreme Court, suffrage organizations, with activists like Susan B. Anthony and Elizabeth Cady Stanton, called for a new constitutional amendment guaranteeing women the same right to vote possessed by men.
By the late 19th century, new states and territories, particularly in the West, began to grant women the right to vote. In 1878, a suffrage proposal that would eventually become the Nineteenth Amendment was introduced to Congress, but was rejected in 1887. In the 1890s, suffrage organizations focused on a national amendment while still working at state and local levels. Lucy Burns and Alice Paul emerged as important leaders whose different strategies helped move the Nineteenth Amendment forward. Entry of the United States into World War I helped to shift public perception of women's suffrage. The National American Woman Suffrage Association, led by Carrie Chapman Catt, supported the war effort, making the case that women should be rewarded with enfranchisement for their patriotic wartime service. The National Woman's Party staged marches, demonstrations, and hunger strikes while pointing out the contradictions of fighting abroad for democracy while limiting it at home by denying women the right to vote. The work of both organizations swayed public opinion, prompting President Woodrow Wilson to announce his support of the suffrage amendment in 1918. It passed in 1919 and was adopted in 1920, withstanding two legal challenges, Leser v. Garnett and Fairchild v. Hughes.
The Nineteenth Amendment enfranchised 26 million American women in time for the 1920 U.S. presidential election, but the powerful women's voting bloc that many politicians feared failed to fully materialize until decades later. Additionally, the Nineteenth Amendment failed to fully enfranchise African American, Asian American, Hispanic American, and Native American women (see § Limitations). Shortly after the amendment's adoption, Alice Paul and the National Woman's Party began work on the Equal Rights Amendment, which they believed was a necessary additional step towards equality.
The Nineteenth Amendment provides:
The right of citizens of the United States to vote shall not be denied or abridged by the United States or by any State on account of sex.
Congress shall have power to enforce this article by appropriate legislation.
Early woman suffrage efforts (1776–1865)
The United States Constitution, adopted in 1789, left the boundaries of suffrage undefined. The only directly elected body created under the original Constitution was the U.S. House of Representatives, for which voter qualifications were explicitly delegated to the individual states. While women had the right to vote in several of the pre-revolutionary colonies in what would become the United States, after 1776, with the exception of New Jersey, all states adopted constitutions that denied voting rights to women. New Jersey's constitution initially granted suffrage to property-holding residents, including single and married women, but the state rescinded women's voting rights in 1807 and did not restore them until New Jersey ratified the Nineteenth Amendment in 1920.
While scattered movements and organizations dedicated to women's rights existed previously, the 1848 Seneca Falls Convention in New York is traditionally held as the start of the American women's rights movement. Attended by nearly 300 women and men, the convention was designed to "discuss the social, civil, and religious rights of women", and culminated in the adoption of the Declaration of Sentiments. Signed by 68 women and 32 men, the ninth of the document's twelve resolved clauses reads, "Resolved, That it is the duty of the women of this country to secure to themselves their sacred right to the elective franchise." Conveners Lucretia Mott and Elizabeth Cady Stanton became key early leaders in the U.S. women's suffrage movement, often referred to at the time as the "woman suffrage movement". Mott's support of women's suffrage stemmed from a summer spent with the Seneca Nation, one of the six tribes in the Iroquois Confederacy, where women had significant political power, including the right to choose and remove chiefs and veto acts of war.
Activism addressing federal women's suffrage was minimal during the Civil War. In 1865, at the conclusion of the war, a "Petition for Universal Suffrage", signed by Elizabeth Cady Stanton and Susan B. Anthony, among others, called for a national constitutional amendment to "prohibit the several states from disenfranchising any of their citizens on the ground of sex". The campaign was the first national petition drive to feature woman suffrage among its demands. While suffrage bills were introduced into many state legislatures during this period, they were generally disregarded and few came to a vote.
Reconstruction Amendments and woman suffrage (1865–1877)
The women's suffrage movement, delayed by the American Civil War, resumed activities during the Reconstruction era (1865–1877). Two rival suffrage organizations formed in 1869: the National Woman Suffrage Association (NWSA), led by suffrage leaders Elizabeth Cady Stanton and Susan B. Anthony, and the American Woman Suffrage Association (AWSA), led by Lucy Stone. The NWSA's main effort was lobbying Congress for a women's suffrage amendment to the U.S. Constitution. The AWSA generally focused on a long-term effort of state campaigns to achieve women's suffrage on a state-by-state basis.
During the Reconstruction era, women's rights leaders advocated for inclusion of universal suffrage as a civil right in the Reconstruction Amendments (the Thirteenth, Fourteenth, and Fifteenth Amendments). Some unsuccessfully argued that the Fifteenth Amendment, which prohibited denying voting rights "on account of race, color, or previous condition of servitude", implied suffrage for women. Despite their efforts, these amendments did not enfranchise women. Section 2 of the Fourteenth Amendment explicitly discriminated between men and women by only penalizing states which deprived adult male citizens of the vote.
The NWSA attempted several unsuccessful court challenges in the mid-1870s. Their legal argument, known as the "New Departure" strategy, contended that the Fourteenth Amendment (granting universal citizenship) and Fifteenth Amendment (granting the vote irrespective of race) together guaranteed voting rights to women. The U.S. Supreme Court rejected this argument. In Bradwell v. Illinois the U.S. Supreme Court ruled that the Supreme Court of Illinois's refusal to grant Myra Bradwell a license to practice law was not a violation of the U.S. Constitution and refused to extend federal authority in support of women's citizenship rights. In Minor v. Happersett the U.S. Supreme Court ruled that the Privileges or Immunities Clause of the Fourteenth Amendment did not provide voting rights to U.S. citizens; it only guaranteed additional protection of privileges to citizens who already had them. If a state constitution limited suffrage to male citizens of the United States, then women in that state did not have voting rights. After U.S. Supreme Court decisions between 1873 and 1875 denied voting rights to women in connection with the Fourteenth and Fifteenth Amendments, suffrage groups shifted their efforts to advocating for a new constitutional amendment.
