Definition
The Woman Suffrage Amendment is the popular historical name for the Nineteenth Amendment to the United States Constitution, ratified on August 18, 1920. The Amendment operates in two sections:
(1) A self-executing prohibition: 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.
(2) An enforcement grant: Congress is empowered to enforce the Amendment by appropriate legislation.
The Amendment extended the federal constitutional guarantee of voting rights to women, who had previously been excluded from the franchise in most states. It did not create the right to vote from whole cloth — voting rights had already been constitutionalized for male citizens of all races by the Fifteenth Amendment in 1870 — but it closed the sex-based exclusion as a matter of federal supreme law, overriding contrary state constitutional provisions and statutes.

Common Confusion
The term "Woman Suffrage Amendment" belongs to a cluster of names for the same instrument. Researchers will encounter it in historical sources under several designations: the Susan B. Anthony Amendment (a tribute name used by advocates during the decades-long campaign), the Nineteenth Amendment, and simply "the Suffrage Amendment." In legal databases and post-1920 judicial opinions, the instrument is indexed almost exclusively as the Nineteenth Amendment. Searching historical newspapers, congressional debates, and pre-ratification legal commentary under "Woman Suffrage Amendment" or "Anthony Amendment" will surface advocacy literature, minority reports, and state ratification debates that do not appear under "Nineteenth Amendment" searches. The two search strategies retrieve overlapping but meaningfully distinct bodies of material.
Do not confuse with state-level woman suffrage amendments, which several states adopted before 1920. Wyoming (1869), Colorado (1893), Utah (1896), and Idaho (1896) each extended full voting rights to women within their borders by state constitutional amendment. Those instruments share the descriptive label but are distinct from the federal Amendment. When a historical source refers to "the Woman Suffrage Amendment" before 1920, context must confirm whether it means the federal proposal pending in Congress or a completed state measure.

Why It Matters in Research
Temporal framing is essential. The federal Amendment was first introduced in Congress in 1878 and was reintroduced in every subsequent Congress for forty-two years before passage in 1919 and ratification in 1920. Law Mind corpus materials spanning that range will treat the Amendment variously as radical proposal, live legislative debate, constitutional crisis, and settled law. The legal status of the instrument changes completely depending on the document's date.
Enforcement clause research is a distinct track. Section II mirrors the enforcement language of the Thirteenth, Fourteenth, and Fifteenth Amendments. Courts applying the Nineteenth Amendment in the post-ratification era have grappled with how broad congressional enforcement power extends — whether Congress may reach facially neutral laws that disparately burden women's voting rights. Researchers approaching the Amendment as a voting rights instrument should follow the enforcement-clause literature generated under the Reconstruction Amendments, which provides the doctrinal framework applied to Section II.
Sex equality extension. The Nineteenth Amendment's prohibition on sex-based voting discrimination has generated modern litigation over whether its logic extends beyond the literal ballot — whether, for example, a state may constitutionally exclude women from jury service or public office on the same reasoning it once excluded them from voting. That doctrinal expansion is tracked in equal protection literature and sits at the intersection of the Nineteenth Amendment and the Fourteenth Amendment's Equal Protection Clause. Corpus researchers connecting these materials should not treat the Amendment as a narrow, self-contained instrument.
State ratification disputes. The 1920 ratification process was contested. Tennessee's ratification — the thirty-sixth and deciding state — was challenged, and the question of whether states that had rejected the Amendment could subsequently ratify (or whether states that had ratified could rescind) produced unresolved procedural arguments that echo in later amendment ratification controversies (notably the Equal Rights Amendment). Historical materials on these procedural disputes are indexed under both the Nineteenth Amendment and under constitutional amendment procedure generally.

Historical Dictionary Support
Bouvier's Law Dictionary reproduces the text of the Amendment verbatim in its two sections without analytical commentary. This is consistent with Bouvier's treatment of constitutional provisions as foundational texts requiring reproduction rather than interpretation. The entry confirms the Amendment's two-part structure — the operative prohibition and the enforcement grant — but provides no doctrinal gloss, no legislative history, and no commentary on the decades of failed congressional action preceding ratification. Researchers should treat the Bouvier entry as a clean text source, not an interpretive resource.
What historical legal dictionaries collectively miss is the Amendment's contested interpretive history. The self-executing force of Section I was not seriously disputed after ratification, but the scope of Section II — and the Amendment's relationship to the emerging constitutional law of sex equality — developed almost entirely through twentieth-century litigation and scholarship not captured in any pre-1920 legal dictionary.

Jurisdictional Note
The Nineteenth Amendment binds every state as supreme federal law. However, state constitutional provisions on voting rights, jury service, and public office that predated the Amendment required separate legal challenge or legislative repeal; the Amendment did not automatically sweep away all sex-based legal distinctions, only those specifically tied to voting. Researchers examining state law in the immediate post-1920 period should not assume automatic compliance.
