Definition

A person who, without being a formal vassal, placed themselves under the protection of a more powerful lord or patron by swearing fealty or fidelity. The affidatus occupied an informal but recognized position in feudal social and legal structure — subordinate in practice, yet not bound by the full obligations of vassalage. The relationship was primarily protective: the affidatus sought shelter under a patron's authority in exchange for loyalty and, typically, fealty.

A secondary, narrower sense appears in Cowell: a woman who has been affianced or betrothed. This usage is largely obsolete and unconnected to the feudal sense.

Common Confusion

Affidatus is frequently treated in historical dictionaries as interchangeable with vassal. Burrill clarifies the distinction: Spelman expressly separates the two, noting that affidati are not vassals properly so called. Hotoman characterized them as quasi-vassals — a formulation that captures their in-between status. The affidatus owed fealty but did not hold land by feudal grant in the conventional sense. Researchers conflating affidatus with villein, serf, or vassal will misread the nature of the dependency relationship being described in a source document.

Why It Matters in Research

This term is almost exclusively a historical and comparative feudal law term. Researchers will encounter it in sources dealing with medieval European land tenure, feudal obligations, and the social hierarchy of the manor system — not in modern litigation or statutory material.

Two traps for corpus researchers: First, the term's root (affidare, to pledge faith) overlaps with the Latin family of words that includes affidavit and affiance. Do not assume that a document using affidatus is discussing sworn statements or betrothal unless context confirms the secondary Cowell meaning. Second, because affidatus describes a quasi-feudal status without a precise English common law equivalent, nineteenth-century American and English legal dictionaries reproduce the term mainly as a glossary item drawn from Spelman rather than as a term of active legal art. Finding it in a primary source signals that the document is either translating or interpreting a continental or medieval source, or is written by a scholar working in comparative feudal law.

The term has no meaningful jurisdictional life in American law. It surfaces in annotated editions of Blackstone, in treatises on feudal tenures, and in glossaries appended to works on real property history. Researchers using Law Mind's corpus of historical treatises on land tenure will find affidatus clustered near discussions of homage, fealty, and commendation.

Historical Dictionary Support

All five source dictionaries agree on the core definition: a non-vassal who secured protection through a pledge of fidelity to a more powerful lord. Black's (both editions) and Bouvier draw the same formulation almost verbatim from Spelman's Glossarium and Blackstone's Commentaries (2 Bl. Comm. 46). Rapalje & Lawrence add a compressed gloss — "tenant by fealty; a retainer" — that helpfully flags the feudal tenure dimension without elaboration.

Burrill provides the most developed treatment and is the most useful for research. He supplies the etymological anchor (from affidare), identifies the Spelman distinction between affidati and proper vassals, quotes Hotoman's characterization of them as quasi-vassals, and separately notes the Cowell meaning of a betrothed woman. No source disputes any other; the variation is in depth, not substance. What the historical dictionaries collectively do not supply is any case law or statutory application, confirming that affidatus never became a operative term of English or American common law — it remained a scholar's term for a feudal category.

Jurisdictional Note

Affidatus has no recognized jurisdictional life in any modern legal system. Its relevance is confined to historical scholarship, comparative feudal law, and the interpretation of medieval documents and treatises. No modern court or legislature employs the term.

Black's Law Dictionary • 1891

One who is not a vassal, but who for the sake of protection has con- nected himself with one more powerful. Spelman; 2 Bl. Comm. 46.

AFFIDATUSmain

Bouvier's Law Dictionary • 1928

One who is not a vassal, but who for the sake of protection has con- nected himself with one more powerful. Spelman, Gloss. ; 2 Bla. Com. 46. AFFIDAVIT (Lat.). In Practice. A statement or declaration reduced to writ- ing, and sworn or affirmed to before some officer who has authority to administer an oath or affirmation. It differs from a deposition in this, that in the lat- ter the opposite party has an opportunity to cross- examine the witness, whereas an affidavit is always taken ex parte; Gresley, Eq. Ev. 418; 3 Blatch. 456. An affidavit includes the oath, and may show what facts the affiant swore to, and thus be available as an oath, although un available as an affidavit; 28 Wis. 460. By general practice, affidavits are allow- able to present evidence upon the hearing of a motion, although the motion may in- volve the very merits of the action; but they are not allowable to present evidence on the trial of an issue raised by the plead- ings. Here the witnesses must be produced before the adverse party. They are gener- ally required on all motions to open defaults or to grant delay in the proceedings and other applications by the defendant ad- dressed to the favor of the court. Formal parts. An affidavit must intelli- gibly refer to the cause in which it is made. The strict rule of the common law is that it must contain the exact title of the cause. This, however, is not absolutely essential; 80 Ill. 307. If not entitled in the cause it cannot be considered in opposition to motion for preliminary injunction; 62 Fed. Rep. 124. The place where the affidavit is taken must be stated, to show that it was taken within the officer's jurisdiction; 1 Barb. Ch. Pr. 601; if the officer fails to append to his signature to the jurat the name of the county for which he is appointed, if it al- ready appears in the caption, it will not be defective; 94 Mich. 617. The deponent must sign the affidavit at the end; 11 Paige, Ch. 173. The jurat must be signed by the officer with the addition of his official title. In the case of some officers the statutes con- ferring authority to take affidavits require also his seal to be affixed. In the absence of a rule of court or statute requiring it, if affiant's name appears in an affidavit as the person who took the oath, the subscription to it by affiant is not nec- essary: 47 Minn. 405; or if his name is omitted in the body of the verification but it is properly signed, it is sufficient; 5 Misc. Rep. 219. If the notary fails to attach his seal to an affidavit of an assignee in insolv- ency, it is not void; 159 Mass. 198; if he omits to add his name in the jurat in affi- davit for writ of certiorari, the court may permit it to be done nunc pro tunc; 58 N. W. Rep. (Wis.) 771; and if he omits to add his title it is not invalid; 143 Mass. 380. In general, an affidavit must describe the deponent sufficiently to show that he is enti- tled to offer it; for example, that he is a party, or agent or attorney of a party, to the proceeding; 7 Hill 177; 4 Denio 71, 258; and this matter must be stated, not by way of recital or as mere description, but as an allegation in the affidavit: 3 N. Y. 41; 8 id. 158. See SUPPLEMENTAL AFFIDAVIT.
