Definition
A national government is the central governing authority of a single sovereign nation — the supreme political institution that exercises unified power over an entire country and its people. It stands in contrast to both subnational governments (states, provinces, localities) and supranational bodies (international organizations, treaty regimes).
In American constitutional usage, the term carries a specific and contested meaning. The federal government of the United States is sometimes called a national government, but the two are not synonyms. The U.S. federal government was designed as a government of enumerated powers operating within a federal system — one in which sovereign authority is divided between the central government and the states. Whether the American system is truly "national" in the full sense, or remains a federal compact of sovereign states, was among the most consequential constitutional disputes of the nineteenth century.

Common Language
Modern common usage (Wiktionary): "The government of a nation, especially as distinct from state, regional, or local governments."
Historical common usage (Webster's 1913): Not separately defined; "national" was understood as "of or pertaining to a nation; common to a whole people or race."
The common usage and the legal meaning track closely on the surface but diverge critically in constitutional analysis. Ordinary speech treats "national government" and "federal government" as interchangeable labels for Washington, D.C. Legal and constitutional scholarship does not. A true national government holds plenary sovereignty over persons and territory; the U.S. federal government holds only delegated powers. The distinction is not pedantic — it determined how courts interpreted congressional authority, how the Civil War was legally framed, and how federalism doctrine developed through the twentieth century.

Common Confusion
NATIONAL GOVERNMENT vs. FEDERAL GOVERNMENT: In casual and even much legal writing, these terms are used interchangeably to describe the U.S. government in Washington. Constitutional purists distinguish them sharply. A federal government, in classical theory, is a creature of a compact among independent sovereign states — it governs states as units, not individuals directly. A national government governs individuals directly and holds supreme, unified sovereignty over the whole population. The U.S. Constitution created something of a hybrid, and the debate over which label applies more accurately was central to antebellum constitutional theory and resurfaced in federalism disputes throughout the twentieth century.
NATIONAL GOVERNMENT vs. CENTRAL GOVERNMENT: "Central government" is the more neutral, comparative-law term for the apex tier of government in any multilevel system. "National government" carries a stronger implication of unified sovereignty and is more common in American and British constitutional discourse.

Why It Matters in Research
The phrase "national government" in historical American sources is a signal term, not a neutral descriptor. When you encounter it in pre-Civil War materials, ask who is using it and why. Federalists and nationalists — Hamilton, Story, Marshall — favored "national government" to emphasize unified sovereign authority. States' rights advocates preferred "federal government" or "general government" to emphasize the compact theory and the retained sovereignty of states. The word choice was an argument, not a label.
In Supreme Court opinions, the shift in preferred terminology across eras tracks broader constitutional commitments. Chief Justice Marshall's opinions lean national; Taney-era opinions often revert to federal or general government. Researchers working in constitutional history must read terminology as substance.
Post-Civil War, the question of whether the United States had become a true national government — with sovereignty flowing from the people directly rather than from state compacts — was largely settled as a political matter, though academic debate continued. Late nineteenth and early twentieth century constitutional scholarship (Burgess, Willoughby) engaged the national/federal distinction as a serious doctrinal question. Modern sources largely abandon the distinction in practice while occasionally invoking it in federalism litigation.
For comparative law research, be cautious: "national government" in British, Commonwealth, or civil law sources does not carry the federal/national tension present in American sources and simply denotes the central government of the nation-state.

Historical Dictionary Support
Bouvier's provides the most useful framing: a national government is distinguished from a federal government by possessing "complete and perfect supremacy over persons and things so far as they can be made the lawful objects of civil government," whereas a federal government is "the government of a community of independent and sovereign states." This distinction — supremacy over persons versus supremacy over states — maps directly onto the Madisonian tension in The Federalist between national and federal elements of the Constitution.
Black's entry is sparse, noting only the contrast with local or subdivisional government. This reflects a later period when the national/federal theoretical distinction had receded from active doctrinal controversy; Black's was more concerned with practical legal usage than with constitutional theory.
Neither historical dictionary captures the full weight of the national/federal debate as it played out in antebellum constitutional law or in the political arguments surrounding secession. Researchers should supplement these dictionary sources with primary constitutional materials and nineteenth-century treatises for that context.

Jurisdictional Note
The national/federal distinction is primarily relevant in jurisdictions with federal constitutional structures — the United States, Australia, Canada, Germany. In unitary states (the United Kingdom prior to devolution, France), "national government" simply means the central government without the theoretical complications present in American usage.
