Definition
A robator (plural: robatores) is a Latin term from old English law denoting a robber — specifically, a sturdy or violent thief who falls upon persons and plunders them of their goods by force. The term is a figure of the law Latin that saturated medieval English legal writing and distinguished this class of offender from the common thief (latro) by emphasis on physical confrontation with the victim.
Common Confusion
Robator and latro are related but distinct terms in medieval legal Latin. Latro referred broadly to a thief or bandit, while robator carried the more specific sense of forcible, person-on-person plunder — closer to what modern law calls robbery rather than theft. A researcher encountering either term in a medieval chronicle or plea roll should not treat them as interchangeable; the distinction tracks the modern criminal law divide between theft and robbery. Separately, robator should not be confused with the Anglo-Norman term feloun or the later common law category of burglator; each describes a different modality of wrongful taking.
Why It Matters in Research
Robator is a term of historical art encountered almost exclusively in medieval English legal records, chronicle sources, and early treatises — it has no living legal significance in modern practice. Researchers will meet it in:
— Plea rolls and eyre records from the twelfth through fourteenth centuries, where robatores appear as a named class of accused alongside murderers and arsonists in presentment proceedings.
— Chronicle sources. Burrill cites Hoveden (Roger of Hoveden), specifically the post part of his chronicle relating to the reign of Richard I, dated 1198. This is a primary source researchers should consult directly; Hoveden's chronicle is available in the Rolls Series edition (Chronica Magistri Rogeri de Houedene, ed. Stubbs, 4 vols.). The passage places robatores in the context of Angevin law enforcement efforts.
— Bracton. Burrill's entry references Bracton's De Legibus et Consuetudinibus Angliae as confirming the definition. Bracton is the foundational treatise for thirteenth-century English common law and treats robbery (rapina or roberia) as a distinct category of felony. Researchers working with Bracton should note that the Thorne translation (Harvard, 1968–1977) and the online Bracton project both provide access to the Latin text alongside translation.
The research trap here is anachronism in translation. A modern reader rendering robator simply as "robber" imports the full baggage of modern robbery doctrine — specific intent, taking from the person, use of force or fear — onto a medieval term whose precise contours were still being worked out by Bracton's time. The term describes a social and legal category, not a technically defined offense with the precision of later common law.
Jurisdictionally, robator is English in origin and application. Researchers in Scottish, Irish, or continental legal history will find different Latin terminology for cognate concepts.
Historical Dictionary Support
Burrill's Law Dictionary is the principal dictionary source for this term, and its entry is characteristically spare but careful. Burrill derives robator from roba (a robe or goods), traces it through Hoveden, and characterizes robatores as "sturdy thieves, who falling upon the persons of men, plunder them of their goods" — the Latin given is latrones validi, qui in personas. The entry references a passage from Bracton as confirmatory, though Burrill's printed text appears incomplete at the point of quotation.
No other major historical legal dictionaries in the Law Mind corpus — not Bouvier, not Black's in its earlier editions — carry this term, which reflects its purely archaic status by the time American legal lexicography was being systematically produced. This is a term that belonged to the English medieval tradition and was already obsolete as a term of art before the colonial period. Researchers relying solely on American legal dictionaries will find nothing; they must go to Burrill, to Bracton directly, and to the chronicle sources Burrill cites.
The derivation from roba (goods, plunder, robe) rather than from a verb of violence is itself instructive: the medieval legal concept centered on the taking of goods rather than the assault on the person, a subtle difference from how modern robbery law weights the force element.
Jurisdictional Note
Robator is specific to English medieval law and appears in legal sources roughly from the Norman period through the late medieval common law. It carries no legal force in any modern jurisdiction and is encountered only as a historical term in archival and chronicle research.
