Definition
Latin and Law Latin phrase meaning "by the country" or "through the country." In its primary procedural sense, *per patriam* refers to trial or determination by jury — the "country" being the community of jurors empaneled to decide a matter of fact. The phrase appears in two closely related contexts:
1. As a substantive description of jury trial: the method of resolving a contested fact issue by submitting it to a jury rather than to a judge or other tribunal. To be tried *per patriam* was to be tried by one's peers — the country at large standing in for the community.
2. As a pleading formula: the concluding language by which a plaintiff, having set out an issue of fact, formally tendered that issue to the jury. The equivalent English form — "and this he prays may be inquired of by the country" — was the standard closing of a plaintiff's pleading that joined issue and invited trial by jury.
Common Confusion
*Per patriam* should not be confused with the modern Latin phrases *per se* or *per curiam*. *Per se* ("by itself") describes something that is inherently so, without need of further proof or context. *Per curiam* ("by the court") identifies an opinion or ruling issued collectively by a court without attribution to a single authoring judge. Neither phrase touches the jury-trial context that defines *per patriam*. Researchers encountering *per patriam* in old English pleading records should not read it as a substantive standard of liability or as a court-authored ruling — it is a procedural marker pointing to jury resolution.
Why It Matters in Research
*Per patriam* is a term of historical English common-law procedure, not modern doctrine. Researchers are most likely to encounter it in:
**Pleading records and year books:** The phrase appears as a fixed formula at the conclusion of declarations and replications where the plaintiff joined issue. Because the phrasing was ritualized, its appearance in a document is a reliable signal that the pleading is tendering a fact question for jury trial — useful when attempting to reconstruct the procedural posture of a historical case.
**Treatises on jury trial and trial by country:** Works addressing the origins and constitutional status of the jury often use *per patriam* as shorthand for the right to jury trial itself. Context matters: sometimes the phrase describes the right in the abstract; other times it appears as the specific closing formula.
**Cross-period confusion:** The Latin phrase fell out of active use as common-law pleading was reformed and simplified through the nineteenth century. Researchers working across periods should be alert to the possibility that later secondary sources use *per patriam* loosely to mean "by jury" without intending any reference to the old pleading formula specifically.
**Corpus navigation tip:** The Law Mind corpus sources for this term (Black's 2nd Ed. and Burrill's) are in agreement on the core meaning but approach it from different angles — Black's emphasizes the pleading formula and its English-language equivalent, while Burrill's ties the phrase more directly to its use in Fleta and the older civil-law influenced tradition. When a primary source you are reading uses *per patriam* without context, Burrill's framing (simple equivalence with jury trial) is usually the safer default reading for pre-modern sources; Black's is more useful for understanding the formal pleading context of the 17th–19th century common law period.
Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) and Burrill's Law Dictionary are consistent in their core identification of *per patriam* with jury trial, but each supplies distinct texture. Black's defines the phrase through the lens of its pleading application, translating it into the English formula used to tender an issue to the country and citing Salkeld for the practice. Burrill's is the more historically precise, grounding the phrase in *Fleta* (the 13th-century legal treatise) and treating it as straightforward equivalence: *per patriam* = by a jury. Neither dictionary provides extended treatment, which accurately reflects the term's status — it is a procedural relic rather than a substantive legal concept, and the historical dictionaries treat it accordingly. Neither source addresses the demise of the formula or its replacement in reformed pleading systems, a gap researchers should keep in mind when working with post-reform sources that may retain the phrase only as a learned archaism.
Jurisdictional Note
*Per patriam* is a term of English common-law origin and is encountered primarily in English and early American legal materials. American courts adopted the inherited pleading vocabulary but the formal formula was displaced by code pleading reforms beginning in the mid-19th century. The phrase has no active operative meaning in any modern jurisdiction.
Encyclopedia Cross-Reference
No Law Mind Encyclopedia entry directly addresses *per patriam* as a procedural formula. The jury-trial right it represents connects broadly to constitutional and procedural topics, but none of the matching entries — which address negligence per se, physical takings, and defamation per se — bear a meaningful relationship to this term. No encyclopedia cross-reference is warranted.
