Definition
Latin (Law Latin): "Pleas of the crown." A collective term in old English law denoting criminal pleas, proceedings, and prosecutions brought in the name of the Crown, as distinguished from pleas between private parties. The phrase reflects the foundational common law concept that serious offenses — particularly felonies and matters touching the King's peace — were understood not merely as wrongs against individuals but as offenses against the sovereign authority itself. As such, their prosecution belonged to the Crown and was conducted through crown courts exercising criminal jurisdiction.
The term carries two related but distinct uses:
1. Procedural: The body of criminal pleas and proceedings cognizable by crown jurisdiction — what we would today call criminal prosecutions.
2. Bibliographic: A title applied to several important early English treatises on criminal law, the most notable being Bracton's treatment in De Legibus et Consuetudinibus Angliae and the later work by Sir Matthew Hale, Historia Placitorum Coronae (written c. 1670s, published posthumously in 1736), which remains a landmark of common law criminal scholarship.
Common Confusion
PLACITA CORONE should not be confused with PLACITA COMMUNIA (common pleas), which governed civil litigation between subjects. The distinction was jurisdictional and structural: common pleas were heard in the Court of Common Pleas; crown pleas fell to the King's Bench and to justices in eyre when traveling the circuits. In historical sources, researchers will encounter both phrases in close proximity — they are opposites, not synonyms. The Latin near-similarity of corona (crown) and communia (common) occasionally produces indexing errors in older digests.
Why It Matters in Research
This is primarily a term of historical and bibliographic significance rather than a term in active modern legal use. Researchers encounter it in three contexts:
First, in medieval and early modern legal manuscripts and printed sources. Bracton's reference at folio 116b treats placita corone as a structural category organizing the criminal law of the realm. Researchers working in pre-1800 English legal sources will see the phrase used as a heading or jurisdictional marker, not as a cause of action with defined elements.
Second, as a bibliographic key. When early treatise writers titled their works on criminal law, "pleas of the crown" was the conventional descriptor. Knowing that placita corone is the Latin equivalent of "pleas of the crown" is essential for navigating catalog records, manuscript collections, and early printed law books held in historical archives. Hale's Historia Placitorum Coronae, Hawkins's Pleas of the Crown, and related works are grouped under this conceptual umbrella.
Third, in tracing the intellectual history of the Crown's role in criminal prosecution. The concept embedded in placita corone — that the state, not the victim, is the proper prosecutor of serious crime — is the doctrinal ancestor of modern public prosecution. Researchers working on the development of prosecutorial authority, the decline of private criminal appeals, or the history of the Attorney General's office will find this term a useful conceptual anchor.
Trap for researchers: In older English records, including plea rolls and eyre records, placita corone appears as a formal heading organizing entries by type of proceeding. Its presence signals that the following entries are criminal in nature. Researchers unfamiliar with the term may misread these sections as civil pleas or miscategorize their content.
Historical Dictionary Support
Burrill's Law Dictionary provides a compact but accurate entry, citing both Bracton (fol. 116b) and Coke (Co. Litt. 284b) as authorities. The citation to Bracton places the term's formal legal usage in the thirteenth century, though the jurisdictional concept it describes is older. Burrill correctly distinguishes the procedural meaning (criminal pleas and prosecutions) from the bibliographic meaning (a title applied to works on criminal law), though he presents them without extended commentary.
What Burrill does not address — and what researchers should know — is the significance of the Crown's theoretical position in these proceedings. The Crown's interest was not merely formal; it grounded jurisdiction, determined venue, shaped available punishment, and explained why certain offenses could not be settled by private composition. That theoretical dimension is traceable through Bracton, Hale, and Blackstone's Commentaries (Book IV), even though none of those sources uses placita corone as their primary organizing term at every point.
