Definition
In feudal law, a *commendatus* (plural: *commendati*) was a person who voluntarily placed himself under the protection of a superior lord through an act of informal homage. The relationship was personal and consensual: the commendatus acknowledged the lord's authority and owed obligations of faith and obedience (*fide et obsequio*), but the arrangement was distinguished from formal feudal tenure in that it required no oath and conveyed no land. The commendatus did not become a vassal in the full technical sense — he received protection in exchange for loyalty and service, but the tie was lighter and less legally encumbered than sworn fealty or a tenurial bond.

Common Confusion
COMMENDATUS vs. VASSAL: These terms are related but not interchangeable. A vassal held land by feudal tenure and was bound by oath. A commendatus entered a protective relationship by voluntary homage alone — no oath, no tenure. The commendatus might be a free person of modest means seeking a powerful patron's shield rather than a landed follower. Conflating the two obscures an important gradation in the feudal hierarchy of obligation.
COMMENDATUS vs. COMMENDATION (the act): The noun *commendatus* describes the person; *commendatio* or *commendation* describes the act or ceremony by which that status was entered. Sources occasionally use the terms loosely. When reading feudal documents, note whether the source refers to the person or the transaction.

Why It Matters in Research
This is a term of medieval Latin feudal law with no continuing operational force in modern Anglo-American doctrine. Researchers will encounter it almost exclusively in three contexts: (1) reading or translating Domesday Book and other early English land records; (2) studying the formation of feudal tenure and the gradations of personal obligation that preceded or coexisted with it; and (3) tracing the conceptual ancestry of protectorate and patron-client relationships in comparative or historical legal scholarship.
The key research trap is anachronism. The feudal vocabulary familiar from later English common law — tenure, seisin, fealty, homage as a formal ceremony — had not fully crystallized when commendation relationships were common. Projecting later technical precision backward will distort interpretation. Burrill's citation to Domesday (via Spelman) is the most useful pointer: Domesday Book records commendati as a distinct class, and the entries have been extensively analyzed in English constitutional and land law scholarship. Researchers working in that vein should move from the dictionary entry directly to Spelman's *Glossarium Archaiologicum* and the secondary literature on pre-Conquest and Conquest-era tenure.
Jurisdictionally, this term has essentially no traction outside English and Continental feudal history. It will not appear in American legal materials as an operative concept.

Historical Dictionary Support
The five source dictionaries converge closely, all drawing from the same two authorities: Spelman's *Glossarium Archaiologicum* and Cowell's *Interpreter*. There is no meaningful disagreement among them on substance.
Burrill provides the most complete treatment and is the most useful of the five. His entry adds the critical qualification absent from the others: the commendatus's obligation was *fide et obsequio* — faith and obedience — but was entered *without oath and without any tenure*. This distinction is doctrinally significant and should not be overlooked. The phrase comes directly from Spelman and is corroborated by Domesday evidence cited there.
Rapalje & Lawrence's formulation — "one who lives under the protection of a great man" — is the most compressed and loses the voluntariness that the other sources emphasize. Bouvier and both editions of Black's are essentially identical, echoing each other without adding independent analysis.
What the historical dictionaries collectively omit: any discussion of how commendation functioned procedurally, what terminated the relationship, or how it interacted with other feudal obligations when a commendatus's protector died or transferred allegiance. Those questions require recourse to primary scholarship on feudal law rather than these dictionary entries.

Jurisdictional Note
Exclusively relevant to English and Continental feudal history. This term carries no operative meaning in any modern common law jurisdiction. American and post-medieval English legal materials will not use it as a living legal concept.
