Definition
A dependent political community formed when citizens or subjects emigrate from their home country to settle and inhabit another territory, while retaining legal and political subordination to the originating state (the "mother country"). The colony lacks full sovereign independence; its governance, laws, and external relations remain subject to the authority of the parent state.
The term carries two related but distinct senses in legal sources:
1. The community itself — the body of settlers and their descendants who have relocated to the new territory.
2. The territory — the land or country so occupied and cultivated by those settlers.
The legal significance of the term lies primarily in questions of sovereignty, jurisdiction, and the status of law. Laws enacted by the mother country may or may not extend to a colony depending on the constitutional relationship between them, and colonial legislatures (where they existed) possessed only derivative, not inherent, legislative authority.
Common Language
Modern common usage (Wiktionary): The Wiktionary entry for "colony" in its primary noun sense describes a group of people who settle in a new territory while maintaining ties to their home country; also used in biology to describe aggregations of organisms. The entry provided here ("to colonize") reflects a verb form only.
Historical common usage (Webster's 1913): "A company of people transplanted from their mother country to a remote province or country, and remaining subject to the jurisdiction of the parent state."
The common meaning and the legal meaning are closely aligned for this term, but the legal definition sharpens one key distinction: dependency and subordination are not merely cultural or social facts but juridical conditions. In legal usage, what matters is not simply that settlers have relocated, but that the resulting political community lacks sovereign independence and remains subject to the mother country's legal authority. The biological or informal uses of "colony" (a colony of ants; an artist colony) carry none of this juridical weight and should not be imported into legal analysis.
Common Confusion
Colony vs. Dependency vs. Possession: These terms are often used loosely or interchangeably in historical sources, but Bouvier's explicitly flags the distinction: "A colony differs from a possession or a dependency." A possession or dependency may be held and governed by a state without any significant settler community or expectation of self-governance, whereas a colony historically implied a transplanted population with some degree of internal political organization. A protectorate is yet another distinct relationship, involving a nominally independent state under the protection of a stronger power without formal annexation. Researchers working with 18th- and 19th-century sources should be alert to these distinctions, as courts and commentators did not always use these terms consistently.
Why It Matters in Research
The legal definition of "colony" is most consequential in historical research touching on public international law, constitutional law, and the law of nations. Several research traps and navigational points are worth noting:
Pre-independence American law is colonial law. Researchers analyzing the legal history of the original thirteen American states must engage with the full corpus of colonial charters, proprietary grants, and royal instructions — documents that establish the dependent legal status of those communities and define the outer limits of their local legislative authority. The term "colony" in those sources carries its full legal weight.
The word "remain subject" does the heavy lifting. Both Black's editions and Bouvier's emphasize continued subordination to the mother country. This is the operative legal condition. Once a colony achieves independence — by declaration, treaty, or recognition — it passes out of this legal category entirely. The transition moment is legally significant and often contested in historical sources.
Colonial legislation and the reception of common law present recurring research problems. Whether English statutes extended to a given colony, and which parts of the common law were "received" as operative in colonial jurisdictions, are questions that generated substantial litigation both before and after American independence. The answer varied colony by colony and turned on the specific terms of each colony's charter or founding instrument.
International law context: In 19th- and early 20th-century international law literature, "colony" functions as a technical classification affecting questions of treaty applicability, extraterritoriality, and the extent of the mother country's international obligations. The Law Mind corpus's international law materials will use the term in this more formal sense.
Post-colonial legal systems: Many contemporary legal systems in Africa, Asia, the Caribbean, and elsewhere retain structural features, statutory codes, and common law inheritances directly traceable to their colonial period. Researchers working in comparative law or legal history of these jurisdictions must understand the colonial legal framework to interpret surviving legal materials accurately.
Historical Dictionary Support
The three historical dictionary sources are in close agreement on the core definition, with only minor textual variation. All three emphasize two elements: the transplanted community of settlers and their continuing subordination to the mother country. Bouvier's is the most analytically useful of the three because it explicitly distinguishes "colony" from "dependency" and "possession," directing researchers to the separate entry on Dependency — a distinction the two Black's editions do not draw.
Black's 2nd Edition cites United States v. The Nancy, 3 Wash. C. C. 287 (Fed. Cas. No. 15,854), as authority for its definition — a useful anchor for researchers who need to trace how American federal courts understood the term in the early national period.
A notable gap in all three historical sources: none engages with the question of what legal status attaches to the inhabitants of a colony — whether they are citizens, subjects, nationals, or something else. This question became intensely litigated in American constitutional law following the Spanish-American War (the Insular Cases), and researchers pursuing that line of inquiry will find the dictionary definitions insufficient starting points. The encyclopedia entries on sovereignty and territorial status will be more productive.
Jurisdictional Note
The legal meaning of "colony" is primarily historical and appears in contemporary legal research most often in constitutional history, international law, and comparative law contexts rather than in live domestic litigation. Where the term retains operational significance — for example, in the interpretation of colonial-era charters, land grants, or statutes that remain in effect in some jurisdictions — the applicable legal framework is that of the specific colonizing power (British, French, Spanish, Dutch, Portuguese) and its relationship with the particular territory. Researchers should not assume that legal rules developed in one colonial system transfer to another.
