Definition
Disparagatio is a Latin term of medieval English law meaning disparagement — specifically, the unlawful matching of a ward in marriage to a person of inferior social standing. The term appears in feudal legal texts governing the rights and obligations of lords over their wards during the period of feudal wardship.
Under the feudal system, when a tenant holding land by knight's service died leaving an heir who was a minor, the lord assumed wardship of both the heir and the heir's lands. This wardship included the power to arrange the ward's marriage — a valuable incident of tenure, since lords could profit by selling or granting the right of marriage. Disparagatio was the offense committed when this power was exercised to match the ward with a spouse of lesser dignity, rank, or blood than the ward's own station. Such a match dishonored the ward and injured the family's social position.
The prohibition against disparagatio was codified in Magna Carta (9 Hen. III, c. 6), which provided that heirs shall be married without disparagement (hæredes maritentur absque disparagatione) — a guarantee that lords, while retaining the power to arrange marriages, could not exploit that power to demean their wards through mismatched alliances.

Common Confusion
Disparagatio is the Latin nominative form of the concept; disparagare is the associated Latin verb, and disparagement is the English derivative term that survived into later common law. Researchers sometimes encounter these forms interchangeably in medieval sources. The modern tort of disparagement (trade libel, injurious falsehood) is an entirely separate legal concept and shares only etymological ancestry with disparagatio. Do not treat the feudal and modern senses as related legal doctrines.

Why It Matters in Research
This term appears almost exclusively in sources treating the feudal incidents of tenure — wardship, marriage, and relief — and is effectively a period-specific term bounded by the era of feudal land tenure in England. Researchers will encounter disparagatio primarily when working with:
Magna Carta scholarship and commentary, particularly analysis of the 1225 reissue (9 Hen. III), which is the version most frequently cited in legal dictionaries and treatises. The original 1215 Magna Carta addressed similar concerns, but the 1225 chapter numbering (c. 6) is the standard reference in the common law tradition.
Feudal tenure treatises. Bracton, Glanvill, and Littleton all address the incidents of wardship and marriage. Any research into the ward's rights against the lord will circle through disparagatio as a limiting principle on the lord's marriage power.
Historical sources written before the abolition of feudal tenures. The Tenures Abolition Act 1660 (12 Car. II, c. 24) eliminated military tenures and with them the practical incidents of wardship by knight's service. After that date, disparagatio as a live legal concern disappears from English law. Sources citing it after 1660 are doing so historically, not as operative doctrine.
The term is absent or marginal in American legal sources. Feudal wardship by knight's service was never systematically established in the American colonies, and the concept has no operative significance in U.S. law. American legal dictionaries that include it do so for historical completeness.
A practical trap: researchers searching for "disparagement" in historical sources may retrieve entries on disparagatio and vice versa, depending on the indexing of the source. Confirm which sense is intended before relying on the entry.

Historical Dictionary Support
Black's (1st and 2nd editions) and Burrill's agree closely on both definition and authority, all three citing Magna Carta (9 Hen. III, c. 6) and providing the same Latin phrase. Burrill adds the Law French form disparagacion and the verb disparagere, which is useful for researchers encountering variant spellings in medieval manuscripts and Year Book citations.
None of the three sources elaborates on the practical operation of disparagatio — what constituted "inferior" rank, how disputes were adjudicated, or what remedy was available to a disparaged ward. For that depth, researchers must go beyond the dictionary shelf to feudal tenure treatises. Pollock and Maitland's History of English Law and Holdsworth's History of English Law both address wardship and marriage in the feudal context with substantially more analytical detail than any of the three dictionary sources.
The historical dictionaries also do not distinguish between disparagatio in the strict sense (marriage to an inferior) and the broader question of whether a ward could refuse a proposed match without forfeiting the marriage value — a related but distinct aspect of the law of wardship. Bracton addresses both.

Jurisdictional Note
Operative only in English law during the period of feudal tenures by knight's service. Abolished as a live legal concept by the Tenures Abolition Act 1660. No significant application in Scots law, Irish law, or American law.
