Definition
Article V is the provision of the United States Constitution that establishes the exclusive procedures by which the Constitution may be amended. It creates two pathways for proposing amendments and two pathways for ratifying them, and it imposes procedural supermajority requirements at every stage to ensure that constitutional change reflects broad, durable national consensus rather than temporary political majorities.
Proposal pathways:
(1) Congressional proposal — Congress may propose an amendment when two-thirds of both the House of Representatives and the Senate approve it.
(2) Convention proposal — On the application of the legislatures of two-thirds of the states (currently 34), Congress must call a convention for proposing amendments. This pathway has never been successfully completed in American history.
Ratification pathways:
(1) State legislatures — An amendment is ratified when approved by the legislatures of three-fourths of the states (currently 38).
(2) State conventions — Congress may direct that ratification occur through specially convened state conventions rather than legislatures. This method was used once, for the Twenty-First Amendment (repeal of Prohibition).
Article V also contains one express entrenchment clause, now of historical significance only: no state may be deprived of its equal suffrage in the Senate without its consent. A second entrenchment clause — protecting the slave trade from congressional interference until 1808 — expired by its own terms.
All twenty-seven amendments to the Constitution have been ratified through the congressional-proposal, state-legislature-ratification pathway.

Common Confusion
"Article V" is sometimes used loosely to refer only to the convention pathway, as in the political shorthand "an Article V convention" or "Convention of States." This usage is technically accurate but incomplete. Article V governs the entire amendment process; the convention is only one of its two proposal mechanisms. Researchers encountering this shorthand in advocacy literature, law review articles, and legislative records should not conflate the convention debate with the full scope of Article V doctrine.
Article V should also be distinguished from Article V of the Bill of Rights — the Fifth Amendment — which addresses grand jury indictment, double jeopardy, self-incrimination, due process, and takings. The two provisions share no subject matter. Bouvier's historical entries indexed under "Article V" capture both contexts, and confusion between them is a genuine research hazard in older indexed sources.

Core Elements
The amendment mechanism has four operative requirements:
1. Supermajority proposal threshold — Two-thirds of both congressional chambers (or two-thirds of state legislatures calling a convention) must agree before any amendment can be proposed. Simple majority support is insufficient.
2. Ratification threshold — Three-fourths of states must ratify. This means 13 states can block any amendment, giving small minorities a constitutional veto.
3. Mode of ratification — Congress chooses whether ratification occurs through state legislatures or state conventions. The choice is Congress's, not the states'.
4. Equal suffrage entrenchment — The one remaining unamendable provision: no amendment may strip a state of its equal vote in the Senate without that state's individual consent. Whether this clause is itself amendable is an open and genuinely contested constitutional question.

Why It Matters in Research
The Article V convention pathway is the most contested unresolved question in American constitutional structure. It has generated continuous scholarly and political debate since the founding era — particularly around three issues: whether Congress has discretion in calling a convention once 34 applications are received, whether a convention can be limited to specific subjects, and whether a "runaway convention" could propose amendments beyond its mandate. Researchers working in constitutional law, federalism, or political reform movements will find this literature substantial and unresolved.
Ratification timing is a recurring research trap. The Fourteenth Amendment was ratified under disputed circumstances involving reconstructed Southern legislatures. The Twenty-Seventh Amendment (congressional pay) was proposed in 1789 and ratified in 1992 — a 203-year gap that raised serious questions about whether ratification deadlines are constitutionally required. The Coleman v. Miller line of cases (1939) addressed whether ratification questions are judicially reviewable at all. These episodes are essential context for understanding the limits of Article V as a legal text versus a political process.
In historical sources — including Bouvier's — the indexing of "Article V" is not systematic. Bouvier reproduces the constitutional text but does not analyze the amendment mechanism as a discrete doctrinal topic. Anderson's entries indexed under Article V are similarly fragmented and occasionally refer to treaty articles, military articles, or code sections rather than the constitutional provision. Cross-referencing against the encyclopedia entry is essential before treating any historical dictionary hit as relevant to the amendment process specifically.
The unamendability of Senate equal suffrage is underexplored in practice but significant in theory. Any proposed structural reform affecting Senate apportionment would immediately implicate this clause, and researchers working on bicameralism, constitutional design, or Senate reform literature should flag it.

Historical Dictionary Support
Bouvier's Law Dictionary reproduces Article V's text in the course of presenting constitutional provisions but does not develop an independent analytical entry on the amendment mechanism as a subject of legal doctrine. This reflects the nineteenth-century approach to constitutional text: reproduction and annotation rather than synthesis. The Fifth Amendment entry in Bouvier is separately developed and far more elaborated, which reinforces the indexing confusion noted above.
Anderson's Dictionary of Law, based on the source material provided, does not appear to contain a substantive entry on Article V as a constitutional amendment mechanism. The Anderson excerpt indexed under this heading addresses a Sino-American treaty provision — almost certainly Article VI of the Burlingame Treaty or a related instrument — not the constitutional amendment procedure. This is a clear example of the multi-document indexing hazard in historical dictionaries, where "Article V" as a label captures unrelated provisions from different legal instruments.
Neither source engages with the convention pathway controversy or the ratification timeline questions that dominate modern Article V scholarship. Historical dictionaries are essentially useless guides to Article V doctrine as it has developed through twentieth and twenty-first century legal debate. They are useful only for the text itself and for confirming what mid-to-late nineteenth century legal reference works chose not to treat as a live doctrinal problem.

Jurisdictional Note
Article V is a provision of federal constitutional law and applies uniformly. State constitutions contain their own separate amendment procedures, which vary considerably and are not governed by Article V. When researching state constitutional reform, researchers should not assume Article V standards apply.
