Definition
A nation is an organized political and social community that exercises or claims sovereign independence, distinguished from other communities by a combination of common characteristics — shared territory, language, customs, historical continuity, and governance. In international law, a nation is treated as a juridical entity capable of rights, duties, and legal relations with other nations.
Two senses of the term operate in legal contexts and must be kept distinct:
1. NATION AS POLITICAL BODY. The organized community of people constituting a sovereign state — an independent body politic with the capacity to govern itself, enter treaties, wage war, and bear rights under international law. Bouvier captures this as "an independent body politic" whose members unite for mutual safety and advantage through combined strength. Critically, Bouvier notes that self-governance alone is insufficient: a body of pirates who govern themselves is not a nation because they lack the legitimacy, purpose, and international recognition that the concept requires.
2. NATION AS PEOPLE OR ETHNIC COMMUNITY. A people bound by common descent, language, customs, and historical experience — what modern discourse sometimes calls an ethnonational group — who may or may not correspond to a single sovereign state. This sense appears in the older dictionaries most prominently and reflects a 19th-century conflation of ethnicity and political organization that modern law has substantially disaggregated.
In U.S. domestic law, the term carries a third, specialized meaning in the context of Indigenous peoples: a federally recognized Indian tribe or Alaska Native entity is commonly referred to as a "nation" or "Indian nation," reflecting the doctrine of tribal sovereignty recognized under federal Indian law. This usage is constitutionally significant and analytically distinct from either sense above.

Common Language
Modern common usage (Wiktionary): Wiktionary's lead definition for "nation" as a surname reflects a metadata artifact rather than the term's primary common meaning. In ordinary contemporary English, "nation" refers to a country or the people composing it — often used interchangeably with "country" or "state" in everyday speech.
Historical common usage (Webster's 1913): "A part, or division, of the people of the earth, distinguished from the rest by common descent, language, or institutions; a race; a stock." Also: "The body of inhabitants of a country, united under an independent government of their own."
The gap between common and legal meaning is subtle but consequential. In common usage, "nation," "country," and "state" are near-synonyms. In legal usage — especially international law — these three terms are carefully distinguished: a state is a juridical entity with defined legal attributes; a nation is a people or political community; a country is primarily a geographic designation. A nation can exist without a state (e.g., the Kurdish people), and a state can contain multiple nations. Researchers who import the colloquial equivalence into legal analysis risk significant error.

Common Confusion
NATION vs. STATE vs. COUNTRY. These terms are interchangeable in common speech but carry distinct meanings in legal and political theory. A state, in international law, requires a permanent population, defined territory, effective government, and capacity to enter relations with other states (the Montevideo criteria). A nation may have all or none of these while still constituting a recognizable people. A country typically refers to the geographic territory. The older legal dictionaries, including Black's and Rapalje & Lawrence, sometimes conflate nation and state — a conflation that modern international law has worked to correct.
NATION vs. INDIAN TRIBE. In federal Indian law, "nation" is frequently used interchangeably with "tribe" or "band," but the legal framework governing Indian nations is entirely distinct from international law concepts of nationhood. Indian nations possess a form of inherent sovereignty that is simultaneously recognized and limited by federal authority — a relationship without a true parallel in international nation-state doctrine.

Core Elements
Bouvier and the Black's dictionaries, read together, suggest that legal recognition of a community as a nation historically required:
1. A defined people or population with shared characteristics (language, customs, descent, or historical continuity).
2. Occupation of or claim to a distinct territory.
3. Some form of organized governance — not mere factual self-governance, but governance oriented toward the community's legitimate mutual benefit.
4. Recognition or acknowledgment by other nations or by the international community (implied in Bouvier's exclusion of pirates, who fail this criterion).
Modern international law refines these through formal frameworks (the Montevideo Convention criteria for statehood), but the four-factor structure visible in the historical dictionaries maps onto those later developments reasonably well.

Why It Matters in Research
Researchers working in the Law Mind corpus will encounter "nation" across sharply different legal contexts, and the term shifts meaning between them without always announcing itself.
INTERNATIONAL LAW SOURCES. In 18th- and 19th-century treatises and cases, "nation" and "state" are used interchangeably. Vattel's Law of Nations, which profoundly influenced early American legal thought, uses "nation" to mean what modern international law calls a "state." Researchers citing historical international law materials must read "nation" in context and not assume modern terminological precision.
FEDERAL INDIAN LAW. This is perhaps the most practically significant trap. "Indian nation" carries a specific, doctrine-laden meaning in American law, invoking the trust relationship, tribal sovereignty, plenary congressional power, and treaty rights. Finding "nation" in a historical federal document or case involving Indigenous peoples triggers an entirely different analytical framework than the same word in a foreign affairs or immigration context. The corpus connections to the INA entry are relevant here: the Immigration and Nationality Act uses "national" in a sense distinct from both tribal sovereignty doctrine and international law, referring to a person owing permanent allegiance to a state without necessarily holding full citizenship.
NATIONAL ORIGIN DISCRIMINATION. Employment law research will encounter "national origin" as a protected category under Title VII. "National origin" is not synonymous with citizenship or race, though it overlaps with both. The connection to "nation" in this context is through the ethnic-community sense of the term, not the sovereign-state sense. Researchers should consult the National Origin Discrimination encyclopedia entry to avoid conflating these concepts.
HISTORICAL SOURCES AND RACIAL THEORY. The 19th-century definitions in Black's and Rapalje & Lawrence reflect an era when "racial origin and characteristics" were considered defining attributes of nationhood. This language appears in sources a researcher will encounter throughout the historical corpus. It reflects a legal-theoretical framework that has been wholly rejected in modern international law and domestic civil rights law, but understanding it is necessary to interpret older authorities accurately.

Historical Dictionary Support
The historical dictionaries largely agree on the core concept — an organized people inhabiting a territory with shared characteristics — but diverge in emphasis and in what they treat as essential.
Black's Law Dictionary (both editions) offers the most developed definition, emphasizing language, customs, historical continuity, and racial origin, while acknowledging that a shared government is typical but not strictly required. This definition is notably ethnic in its framing, reflecting late 19th-century European nationalist theory more than a pure legal-technical standard.
Rapalje & Lawrence is sparser, defining a nation as "a people, distinguished from another people, generally by their language, origin, or government" — a simpler formulation that avoids the racial language of Black's while preserving the distinction between ethnic and political senses.
Bouvier takes the most explicitly legal and political approach, grounding the definition in social contract concepts: a nation is a body politic united for mutual safety and advantage. Bouvier's exclusion of pirates is analytically useful — it implies that mere factual self-governance is insufficient; legitimacy and purpose matter to the legal concept.
Anderson's Dictionary of Law does not appear to contain a relevant entry for this term; the source material supplied under Anderson's header concerns rules for proper names, which is unrelated.
What the historical dictionaries collectively miss: they do not address the special status of Indigenous nations within the American federal system, which was already a developed area of law by the time these dictionaries were compiled. The Cherokee Cases and subsequent federal Indian law doctrine are invisible in these definitions. Researchers should not treat the historical dictionary definitions as comprehensive guides to how "nation" functions in that distinct legal context.

Jurisdictional Note
The meaning and legal significance of "nation" varies considerably between international law, U.S. federal law, and U.S. federal Indian law. In international contexts, the term functions within frameworks largely established by treaty and customary international law. In U.S. domestic law, "national" has a statutory definition under the Immigration and Nationality Act that is specific and technical. Federal Indian law represents a third, entirely self-contained framework in which tribal nations occupy a constitutional and doctrinal position unlike any other entity in American law.
