Definition
A federalist is a person who advocates for federalism — a system of government in which sovereignty is constitutionally divided between a central authority and constituent political units such as states or provinces. In American legal and historical usage, the term carries a more specific meaning: a supporter of the federal Constitution as framed in 1787 and ratified in 1788, and more narrowly, a member or adherent of the Federalist Party that dominated early American national politics under Presidents Washington and Adams.
In modern legal discourse, the term appears most often in three contexts:
1. Constitutional theory: A federalist position favors robust national governmental authority, or alternatively (in contemporary usage) emphasizes the structural balance between federal and state power as a constitutional value. The term's valence has shifted over time — see COMMON CONFUSION below.
2. Political-historical: A participant in or sympathizer with the founding-era Federalist movement, associated with Alexander Hamilton, John Jay, and James Madison as authors of The Federalist Papers (1787–88).
3. Comparative and international: In Canadian constitutional discourse, a federalist is specifically one who supports Québec's continued participation in the Canadian federal union, in opposition to sovereigntist or separatist movements. This usage is narrow and context-dependent.

Common Language
Modern common usage (Wiktionary): An advocate of federalism generally; in Canadian political discourse, a supporter of Québec remaining within Canada's federal system; occasionally, a covenantalist in theological contexts.
Historical common usage (Webster's 1913): "An advocate of confederation; specifically (Amer. Hist.), a friend of the Constitution of the United States at its formation and adoption; a member of the political party which favored the administration of president Washington."
The gap between common and legal meaning here is not definitional but directional: common usage and Webster's 1913 point consistently to the founding-era Federalist as one who favored a stronger central government over the states. Contemporary legal and political discourse — particularly in American constitutional law — has partly inverted this: self-described "federalists" today often champion states' rights and limits on federal power. A researcher who assumes the modern common meaning maps cleanly onto the historical legal meaning will misread founding-era sources, antebellum debates, and even twentieth-century constitutional scholarship.

Common Confusion
FEDERALIST vs. FEDERALISM vs. ANTI-FEDERALIST: These three terms are routinely conflated in secondary literature. A Federalist (capital F, historical) was a proponent of ratifying the Constitution and generally favored national governmental strength — the opposite of an Anti-Federalist, who feared centralized power and demanded stronger protections for states and individual liberties. "Federalism" as a structural constitutional principle is neutral as between these camps; it describes the divided-sovereignty system both sides ultimately inhabited. Modern "federalists" in the judicial philosophy sense — favoring enumerated federal powers and reserved state authority — align more closely with the historical Anti-Federalist position than with the capital-F Federalist Party. This inversion is a persistent source of confusion in constitutional research.
THE FEDERALIST (Papers) vs. THE FEDERALIST PARTY: The Federalist Papers are a collection of 85 essays arguing for ratification of the Constitution. The Federalist Party is the political organization that succeeded the ratification movement and dissolved in the 1820s. Authors of The Federalist Papers (particularly Madison) later broke with the Federalist Party. Treating them as coextensive misreads both the essays and the party's later positions.

Why It Matters in Research
Researchers working in the Law Mind corpus will encounter "federalist" in at least three distinct registers, and context determines meaning almost entirely.
In founding-era primary sources (1787–1800), "Federalist" nearly always means a supporter of the Constitution or a member of Hamilton's political coalition. Its antonym is "Anti-Federalist" or "Republican" (the Jeffersonian variety). Do not import modern connotations.
In nineteenth-century legal materials, the Federalist Party's legacy surfaces in constitutional interpretation debates — particularly concerning implied powers, the national bank, and commerce clause scope. Anderson's Dictionary of Law, reflecting its late nineteenth-century vantage, treats "federalist" primarily in this historical-political sense.
In twentieth and twenty-first century legal scholarship, "federalist" often appears as an adjective modifying constitutional philosophy (e.g., "federalist principles," "new federalism"), where it typically signals concern for state sovereignty against federal encroachment — again, nearly the reverse of the founding-era meaning.
The Federalist Papers themselves are a distinct research object: they are primary sources for original-meaning constitutional interpretation, widely cited by courts, and the subject of extensive Law Mind Encyclopedia coverage. Searching for "federalist" in corpus materials without distinguishing among these registers will produce misleading result sets.
Note also that Anderson's Dictionary of Law does not contain a substantive entry for "federalist" as a legal term of art — the source material associated with this term in that dictionary appears to be a misprint or editorial artifact (text referencing malfeasance and misfeasance). This confirms that "federalist" functions in legal dictionaries as a historical-political term rather than a technical legal one, and researchers should not expect doctrinal definition in that tradition.

Historical Dictionary Support
Anderson's Dictionary of Law does not offer a substantive definition of "federalist" as a legal term. The source text associated with this entry in that dictionary is clearly corrupted or misattributed — it references Georgia bills of exception and the definitions of malfeasance and misfeasance, with no connection to the term. Researchers should treat Anderson's as silent on this entry.
Webster's 1913 provides the most useful historical baseline: federalist as constitutional supporter and Washington-administration partisan. This meaning was stable through most of the nineteenth century and aligns with how founding-era legal and political actors used the term.
What the historical dictionaries collectively miss is the semantic reversal that occurs in twentieth-century constitutional discourse. Neither Anderson's nor Webster's anticipates a "federalist" as one skeptical of expansive federal power — yet this is precisely how the term functions in contemporary judicial philosophy, think-tank nomenclature (cf. The Federalist Society, founded 1982), and academic constitutional theory. Legal researchers relying solely on historical dictionary sources will be ill-equipped to read modern materials accurately.

Jurisdictional Note
In the United States, "federalist" is primarily a term of constitutional history and political theory rather than operative legal doctrine; no jurisdiction defines it by statute. In Canada, the term has active political-legal resonance in Québec constitutional debates, where it describes a defined position in ongoing sovereignty disputes. Researchers using the term across jurisdictions should specify which usage is intended.
