Definition

Nationality is the legal relationship between an individual and a state that determines membership in that state's political community. It establishes the individual's political status—particularly with respect to allegiance, protection, and the rights and duties owed between person and sovereign. Nationality is acquired by birth (whether by place of birth or parentage) or by naturalization.

As a legal concept, nationality operates along two distinct axes:

1. PERSONAL NATIONALITY: The bond between an individual and a state. This governs which state owes the individual diplomatic protection, which state may demand allegiance, and which body of national rights and obligations applies. Nationality differs from domicile: nationality determines political status; domicile determines civil status. The two may, and often do, diverge.

2. VESSEL NATIONALITY: The legal relationship between a ship and a state. A vessel's nationality—evidenced by its flag and registration—determines which state's laws govern the ship, which state bears responsibility for its conduct on the high seas, and how it is treated under international law. Bouvier's notes that the term is "in frequent use with regard to ships."

Common Language

Modern common usage (Wiktionary): Nationality carries both a legal sense—legal membership of a particular nation or state—and a cultural sense: a people sharing common origin, language, or culture, not necessarily constituting a formal state.

Historical common usage (Webster's 1913): Emphasis falls heavily on the cultural and sentimental dimensions—patriotism, national character, race or people determined by common language rather than political division.

The gap matters for legal research. In ordinary usage, nationality frequently merges with ethnicity, culture, or national origin. In law, nationality is a formal status—a legal relationship with a specific sovereign—not a description of ethnic or cultural identity. A person may have a nationality entirely different from their ethnic or cultural background. Researchers using historical sources must be alert to this slippage: passages describing "nationality" in 19th-century texts may be using the term in its cultural sense rather than its legal one.

Common Confusion

NATIONALITY vs. CITIZENSHIP: These terms are related but not identical. Citizenship typically denotes full membership in a political community, including the right to participate in governance. Nationality is the broader category: all citizens have a nationality, but not all nationals are full citizens. The distinction became formally significant in U.S. law with respect to nationals of territories like American Samoa who owe allegiance to the United States but do not hold full citizenship status.

NATIONALITY vs. DOMICILE: Both determine personal status, but they govern different spheres. Nationality governs political and international status—allegiance, diplomatic protection, the rights of states to act on one's behalf. Domicile governs civil status—which jurisdiction's laws apply to succession, family law, and personal obligations. A person can be a national of one state while domiciled in another for extended periods.

NATIONALITY vs. NATIONAL ORIGIN: In antidiscrimination law, national origin is a distinct statutory category. It refers to the country from which a person or their ancestors came—an ancestral or geographic concept—and does not require current legal nationality. Someone may face national origin discrimination based on perceived ancestry regardless of their actual legal nationality.

Why It Matters in Research

Researchers working across different periods of the corpus will encounter nationality operating in different legal registers simultaneously, and conflation produces errors.

In public international law materials, nationality is the foundational link between individual and state. Historical sources treat it as the predicate for diplomatic protection, extradition, and the jurisdiction of prize courts over captured vessels. The vessel-nationality usage appears throughout admiralty sources and requires care: ship nationality and personal nationality follow different rules of acquisition and recognition.

In immigration law materials, nationality acquires a specific statutory meaning under the Immigration and Nationality Act. Researchers moving between common law treatises, international law sources, and modern administrative materials should not assume consistent usage across these domains.

The nationality-domicile distinction is a persistent trap in historical conflict-of-laws materials. 19th-century English and American courts worked through significant doctrinal confusion about which concept governed which aspects of personal status. Sources from this period may use the terms loosely or treat the distinction as contested rather than settled.

For antidiscrimination research, nationality and national origin must be carefully distinguished. Statutes prohibiting discrimination on the basis of national origin do not require that the affected person hold or have held any particular nationality. Importing the nationality-as-legal-status concept into national origin analysis is a research error with doctrinal consequences.

The Savigny reference preserved in Black's—nationality as opposed to territoriality—points toward a theoretical framework in private international law that treats nationality as the personal law governing an individual wherever they travel. This principle, dominant in continental European systems, competed with the common law emphasis on domicile as the primary determinant of personal law. Researchers in comparative private international law will need to track this divide carefully.

Historical Dictionary Support

The three historical dictionaries converge on the core definition: nationality is the quality arising from belonging to a nation or state, determining political status especially with respect to allegiance. Both Black's and Rapalje & Lawrence offer nearly identical formulations, reflecting the common source tradition in 19th-century American legal lexicography.

Bouvier's is more expansive and more useful on two points. First, it recognizes that nationality may be determined by multiple factors—origin, naturalization, domicile, residence, trade, or other circumstances—which reflects the unsettled state of international law on the subject during the period of Bouvier's drafting. Second, it explicitly flags the vessel context, which the other dictionaries address incompletely.

Black's partial preservation of the Savigny reference to nationality versus territoriality is a significant theoretical marker. It signals that the drafters understood nationality as implicated in the continental personal law debate, even if American common law practice generally followed domicile rather than nationality for private law purposes.

What the historical dictionaries miss: they do not address the nationality-citizenship distinction in terms of graduated membership—the category of non-citizen national was not a pressing issue when these works were written, but is essential for researchers working with 20th-century territorial and immigration materials. They also do not address the antidiscrimination law context, which developed after these dictionaries were compiled.

Jurisdictional Note

International law and the law of individual states may reach different conclusions about a person's nationality, and dual or stateless conditions arise from these gaps. In U.S. law, the distinction between citizen and non-citizen national has specific statutory content under the Immigration and Nationality Act, applying primarily to persons born in certain territories. In private international law, common law jurisdictions generally use domicile rather than nationality as the personal connecting factor; civil law jurisdictions generally use nationality. This difference affects which sources govern conflict-of-laws analysis depending on the forum.

NATIONALITYmain

Black's Law Dictionary • 1891

That quality or char- acter which arises from the fact of a person's belonging to a nation or state. Nationality determines the political status of the indi- vidual, especially with reference to allegi- ance; while domicile determines his civil status. Nationality arises either by birth or by naturalization. According to Savigny, "nationality" is also used as opposed to "ter- ritoriality," for the purpose of distinguish- ing the case of a nation having no national territory; e. g., the Jews. 8 Sav. Syst. § 346; Westl. Priv. Int. Law, 5.

Bouvier's Law Dictionary • 1928

Character, status, or condition with reference to the rights and duties of a person as a member of some one state or nation rather than an- other. Nationality may be determined from origin, naturalization, domicil, residence, trade, or other circumstances; 1 Halleck, Int. L. 403. The term is in frequent use with regard to ships. Nationality determined by one's birthplace or parentage is called nation- ality of origin; that which results from naturalization, is by acquisition. A woman, upon marriage acquires the nationality of her husband; Morse on Citizenship 142. In feudal times, nationality was determined exclusively by the place of birth, jure soli; but under the laws of Athens and Rome the child followed that of the parents, jure sanguinis. "Of these two tests, the place of birth and the nationality of the father, neither is at present adopted without qual- ification by British, French, or American law. The laws of these countries exhibit, in fact, different combinations of the two, Great Britain and the United States laying chief stress on the place of birth, while in France the father's nationality determines, though not absolutely and in all cases, that of the child; and this latter theory has found acceptance among other European nations," as Belgium, Bavaria, Prussia, and Spain. Morse, Citizenship 10. Subject to the act of 1870, English jurists almost unanimously deny the right of ex- patriation to the extent of a change of primitive allegiance, without the consent of the liege lord. By the laws of France, a Frenchman loses his native character by naturalization in a foreign country, by accepting office under a foreign govern- ment without the permission of his own, or by so establishing himself abroad as to show an intention of never returning. In Austria national character is lost by author- ized emigration from the empire without the intention of returning, and it is equally lost if effected without permission. In Germany, it is lost by unauthorized emi- gration except in the case of a German nat- uralized in the United States. Spain and the Spanish American Republics provide for the loss of Spanish nationality upon the acquisition of a new national character; 1, Halleck, Int. L. 403. The native, national character lost or suspended by a foreign domicil, easily reverts; id. 429. A general rule is recommended by West- lake: "Legitimate children, wherever born, are regularly members of the state of which their parents form part the moment of their birth; but they may choose as their nationality the place of their birth."
