Definition
A Latin and Law Latin term meaning "a thousand." Used in old English legal texts and records as a numerical designation, typically appearing in contexts where quantities were measured or expressed in units of one thousand — such as counts of goods, tolls, or other enumerable items subject to legal regulation or taxation.
Common Confusion
Miliare should not be confused with the classical Latin miliarium or milliarium, meaning a milestone or a measure of distance (the Roman mile). The two words share a common root (mille, "thousand") but diverge in legal and geographical usage. In a legal document, miliare almost always refers to a count of one thousand units of goods or items; miliarium in geographical or road-law contexts refers to distance. Context — particularly whether the surrounding text discusses quantity of commodities or measurement of land and roads — is the key to correct identification.
Why It Matters in Research
Researchers encountering miliare in medieval English legal records should treat it as a straightforward numerical unit rather than a term of legal art with substantive doctrinal content. Its significance is almost entirely linguistic and paleographic: the word appears in Law Latin documents where a scribe or drafter used classical or medieval Latin vocabulary in place of vernacular numerals or English terminology.
The primary research trap is misreading or mistranslating the term in context. In toll schedules, market regulations, customs records, and similar administrative documents, quantities of goods were frequently expressed in Latin, and miliare (or its variant forms, including mille and milliare) could refer to counts of items — fish, hides, nails, and other commodities commonly enumerated by the thousand in medieval trade law. Confusing the unit with a reference to a place, a proper name, or a measure of distance (see COMMON CONFUSION below) would distort the meaning of the surrounding passage.
The Fleta citation recorded in Burrill points to a well-known 13th-century English legal treatise, confirming that the term was in active use in formal juridical Latin of that period. Researchers working with Fleta or comparable treatises (Bracton, Britton, the Year Books) should expect Latin numerical vocabulary throughout and verify each instance against context to determine whether a quantity, a toll rate, or a legal threshold is being expressed.
Because miliare appears almost exclusively in pre-modern sources, it is unlikely to surface in post-medieval case law or statutory material. Researchers working in early modern or modern corpora who encounter the word are probably dealing with a quotation from or reference to an earlier text rather than a living legal usage.
Historical Dictionary Support
Burrill's Law Dictionary provides the sole historical legal dictionary entry for this term. Burrill defines it concisely as "a thousand" and anchors the usage to Fleta, lib. 2, c. 12, § 2. This is an appropriately spare treatment: the term carries no contested doctrinal meaning and requires no extended elaboration. Burrill correctly identifies it as Law Latin and as belonging specifically to old English law — a useful signal that the term's natural habitat is the medieval English legal corpus rather than Roman law sources proper, where mille or milia would be the more common forms.
Other major historical legal dictionaries — including Jacob's Law Dictionary, Tomlin's Law Dictionary, and Black's early editions — do not appear to carry a separate entry for miliare, suggesting the term was recognized as sufficiently self-explanatory (once its Latin root was understood) that extended definition was unnecessary. Its absence from those sources also reflects how rarely the term required interpretation in legal proceedings by the time those dictionaries were compiled.
No significant divergence or interpretive dispute appears in the historical record regarding this term. It is a stable, unambiguous numerical unit.
Jurisdictional Note
Miliare as a legal term is specific to medieval English law Latin. It does not appear as a term of art in Scots law, canon law, or continental civil law sources in the same usage documented by Burrill. Researchers working in non-English medieval legal corpora should verify local Latin usage independently.
