Definition
In international law, a captor is one who seizes enemy property during wartime. In the strictest and most historically prominent legal sense, a captor is one who takes a prize at sea — that is, who captures an enemy vessel or its cargo as a lawful act of war. More broadly, the term extends to any belligerent who seizes property belonging to an enemy on land or sea.
Burrill identifies an older, narrower domestic law usage: in early English law, a captor could mean a lessee or a person who seized cattle as a distress — a taker in the general possessory sense. This usage is archaic and appears only in very old pleading and property contexts.

Common Language
Modern common usage (Wiktionary): One who holds a captive or captives; one who has caught or captured someone or something.
Historical common usage (Webster's 1913): One who captures any person or thing, as a prisoner or a prize.
The common usage centers on the capture of persons — a kidnapper, a jailer, a soldier holding prisoners. The legal meaning is almost exclusively focused on property, specifically enemy property seized under the laws of war. A researcher who approaches the term through its common meaning will expect it to govern the treatment of prisoners; in the legal corpus it most often governs the ownership, adjudication, and distribution of seized goods and vessels. The distinction matters: prize law concerns things, not people.

Common Confusion
CAPTOR and CAPTOR'S RIGHTS (prize rights) are closely linked but distinct. The captor is the actor; the legal question historically was whether the captor acquired personal title to the seized property or whether title vested in the sovereign, with the captor receiving only a share under municipal prize law. As Bouvier notes, early law treated seizure as conferring direct ownership on the individual captor; modern law treats the property as vesting in the state, with distribution to captors governed by statute or prize court decree. Researchers conflating the two may misread earlier authorities as stating the modern rule.
CAPTOR should also be distinguished from CAPTOR in the domestic distress context (Burrill's old English usage) — that usage involves private law remedies for debt or trespass and has no connection to the international law prize sense.

Why It Matters in Research
The term sits almost entirely within the law of prize and the broader law of war, making it a gateway concept for navigating admiralty and prize law materials. Several navigational points bear attention:
First, the historical shift in title theory is significant for reading older sources accurately. Authorities predating the systematic development of prize courts — and some early American materials — speak of the captor acquiring title by the act of seizure. Later sources, including Kent's Commentaries and the prize court tradition, treat title as vesting in the sovereign with distribution as a matter of prize law. Applying the older rule to a later dispute, or vice versa, produces error.
Second, the sea/land distinction matters. The strict prize sense applies to naval captures. Land captures of enemy property have a somewhat different doctrinal history and are less thoroughly systematized in Anglo-American law. Sources using "captor" without qualification most often mean the maritime context.
Third, Burrill's domestic law sense — a taker, a distrainor — appears in very old English pleading materials and early common law treatises. It is functionally extinct as live doctrine but will surface in historical corpus searches. Researchers working in medieval or early modern English legal materials should flag this usage and not read it through the international law lens.
Fourth, Bouvier raises the point of captor liability to original owners — an important thread in prize law concerning wrongful capture or capture without proper condemnation. This connects to the jurisdiction of prize courts and the question of sovereign immunity.

Historical Dictionary Support
The four source dictionaries are in broad agreement on the primary international law definition, with Black's (both editions) and Burrill tracking Blackstone and Kent closely. Bouvier adds the most substantive doctrinal content, noting both the title-vesting question and captor liability — points the other dictionaries omit.
Burrill is alone in recovering the old English domestic law sense (taker, lessee, distrainor), which he supports with citations to Fleta and Townsend's Pleadings. This usage is genuinely distinct from the international law definition and reflects Burrill's broader effort to trace legal terms through their Latin and early common law roots.
None of the source dictionaries address the question of who qualifies as a captor in a corporate or crew sense — whether the term refers to the individual sailor, the commanding officer, the vessel, or the state. Prize law resolved this through statutory distribution schemes, but the dictionaries leave it unaddressed. Researchers should consult prize court materials and Kent's Commentaries directly for that question.

Jurisdictional Note
Prize law in the United States was administered by federal courts from the founding, with the law of capture governed by the law of nations as incorporated into federal common law and, for wartime prizes, by congressional prize acts. English prize law developed through the High Court of Admiralty. The substantive rules on captor's title and distribution differ in detail between the two systems, and researchers should not assume that English prize authorities state American law without checking for divergence.
