Definition
Latin. Literally, "to bear a wolf's head." A phrase from medieval English and Roman law denoting the legal status of an outlaw — a person so completely stripped of legal protection that anyone who encountered them could lawfully kill them without legal consequence. The outlaw was treated not as a human being under the protection of the law but as a dangerous animal, equivalent to a wolf, whose head could be taken and presented for a reward. The phrase thus captures both the formal declaration of outlawry and its practical, violent consequence: the condemned person was exposed to death at the hands of any subject, with no remedy and no protection.

Common Confusion
LUPINUM CAPUT GERERE should not be confused with mere banishment or exile. Banishment removes a person from a territory; outlawry removes a person from the law itself. The banished person retains legal personhood and protection in other jurisdictions. The outlaw under lupinum caput gerere had none — they could be killed on sight within the realm, and their killer incurred no liability. Similarly, the phrase should not be confused with attainder, though the two concepts overlapped historically. Attainder operated by statute or judgment and had specific consequences for property and blood; outlawry operated procedurally, arising from a fugitive's failure to appear, and its most extreme consequence was the wolf's-head status described here.

Why It Matters in Research
This phrase appears almost exclusively in historical legal sources and is not operative in any modern common law jurisdiction. Researchers encountering it in primary sources — medieval Year Books, early common law treatises, or historical records of criminal proceedings — should understand it as a technical marker of the outlawry process, not a general metaphor.
The phrase is a reliable indicator that a source is describing the most extreme form of outlawry, as distinguished from lesser forms of legal disability. When you see lupinum caput gerere in a medieval or early modern source, the text is signaling that the subject has been formally declared an outlaw following failure to appear in a criminal proceeding, and that the kill-on-sight consequence has attached.
Researchers should also note that the phrase encodes a specific reward mechanism. It is not merely a statement of vulnerability; it implies an active incentive for third parties to hunt and kill the outlaw. This distinguishes it from passive lack of protection.
The reference to Cowell in both Black's editions points researchers to John Cowell's Interpreter (1607), an early legal dictionary and a primary source for this and related terms. Cowell himself drew on earlier civilian and common law materials. Researchers working on the history of outlawry, the development of due process, or the legal treatment of fugitives from justice in English legal history should consult Cowell directly and trace the concept through Bracton's De Legibus et Consuetudinibus Angliae, where the wolf's-head analogy appears in foundational form.
The phrase also has significance for legal historians studying the relationship between legal personhood and protection. The outlaw's status as caput lupinum — a wolf's head — is one of the starkest historical illustrations of the idea that legal protection is contingent on submission to legal process. It is a useful reference point in scholarship on civil death, legal incapacity, and the history of rights.

Historical Dictionary Support
Both Black's editions reproduce the same entry verbatim, sourcing it to Cowell without elaboration. The definition is accurate as far as it goes but is notably compressed. Neither edition distinguishes the procedural steps required before this status attached, nor do they note the gradual obsolescence of outlawry in English law following the Criminal Law Act 1967 (UK) and its predecessors, which formally abolished outlawry in England and Wales. Neither edition addresses whether or how the concept translated into American law; it did not, in any operative sense, though the phrase appears in American legal dictionaries inherited from English sources.
The wolf's-head imagery has deep roots. Bracton used it in the thirteenth century to describe the outlaw's condition. The concept appears in Anglo-Saxon law as well, where the outlaw (wulfesheafod) was similarly characterized. Black's compressed entry reflects this long lineage without tracing it, which is appropriate for a dictionary but leaves the researcher without the historical depth that primary sources provide.

Jurisdictional Note
This concept has no operative force in any modern common law jurisdiction. Outlawry as a formal legal procedure was abolished in England and Wales. American law never adopted the wolf's-head form of outlawry. The phrase is encountered only in historical legal materials and scholarship.
