Definition
Delicta is the Latin plural of delictum. In legal usage, the term refers collectively to wrongs, offenses, or criminal acts — particularly as understood within the Roman law tradition and its civilian successors. In the Roman law framework that underlies much of Western legal development, delicta encompassed private wrongs giving rise to civil obligations (analogous to modern torts) as well as public offenses subject to state punishment. The singular delictum carries the same meaning for a single wrong or offense; delicta is used when treating the category collectively or listing multiple offenses.
The term appears most often in legal writing and treatises dealing with conflict of laws, private international law, and the historical foundations of tort liability, where the question of which jurisdiction's law governs an offense committed in one place and tried in another is raised under the maxim locus delicti commissi — the place where the wrong was committed.

Common Confusion
Delicta and crimina were formally distinguished in Roman law. Crimina were public offenses prosecuted by the state; delicta were private wrongs for which the injured party sought a civil remedy. Over time — and especially in later civil law scholarship absorbed into common law treatises — the terms were used more loosely and sometimes interchangeably, as Burrill's entry illustrates by glossing delicta simply as "crimes; offences" without preserving this distinction. Researchers reading historical sources should note whether the author is writing strictly in the Roman tradition (where the distinction matters) or using delicta in the looser sense of wrongs generally.

Why It Matters in Research
Researchers encounter delicta most frequently in two contexts within the Law Mind corpus.
First, conflict of laws. The maxim quoted in Burrill — delicta puniuntur juxta mores loci commissi delicti, et non loci ubi de crimine cognoscitur (crimes are punished according to the customs of the place where they are committed, and not the place where they are tried) — appears recurrently in early American and English treatises on private international law. Kent's Commentaries cites it in the foundational discussion of territorial sovereignty and the extraterritorial reach of penal law. This maxim is a precursor to the modern lex loci delicti rule in choice-of-law analysis. When reading 18th and 19th century conflict-of-laws materials, delicta signals the author is engaging with this territorial principle.
Second, Roman law and civil law foundations. In treatises tracing the history of tort or obligation, delicta appears as the Roman law category from which modern civil liability for private wrongs descends. The four principal delicta of Roman law — furtum (theft), rapina (robbery), damnum injuria datum (wrongful damage to property), and injuria (insult or personal wrong) — are the ancestral categories behind much tort doctrine. Historical sources that use delicta without explanation assume familiarity with this framework.
A trap in historical sources: because delicta was used loosely by some common law writers to mean simply "wrongs" or "offenses" without the Roman distinction from crimina, a reader cannot assume the author is preserving the private/public distinction unless the context makes it explicit. Burrill himself does not flag this ambiguity.
The term also appears in the maxim in pari delicto potior est conditio defendentis (in equal fault, the position of the defendant is stronger), which remains a recognized defense principle in Anglo-American law. That maxim uses delicto (ablative singular), but the underlying concept connects directly to the delicta framework. Researchers should index both forms when searching the corpus for this doctrine.

Historical Dictionary Support
Burrill's Law Dictionary defines delicta as the plural of delictum and glosses it as "crimes; offences," citing the locus commissi delicti maxim with attribution to Bartholus (the great 14th-century Italian jurist and commentator on Roman law) via Henry on Foreign Law, and to Kent's Commentaries. This entry is useful for confirming the conflict-of-laws application but thin on the Roman law substance. Burrill does not explain the Roman private/public distinction, does not treat the four classical delicta, and does not connect the term to the in pari delicto defense — gaps that limit the entry's usefulness for researchers working in tort history or Roman law foundations.
The citation to Bartholus is significant: Bartholus de Saxoferrato was the primary medieval authority on the territorial application of law, and his formulations on locus delicti shaped European private international law for centuries. Kent's citation in his Commentaries carried that tradition into early American legal thought. Researchers tracing the intellectual lineage of modern choice-of-law rules for torts will find these citations genuine waypoints in the doctrine's development.

Jurisdictional Note
The term delicta itself is not jurisdiction-specific — it is a Latin term of art appearing across civil law and common law systems. The locus delicti rule it is associated with, however, varies significantly: civil law countries generally apply it rigidly, while American states have largely moved toward interest-analysis and most-significant-relationship approaches under the Restatement (Second) of Conflict of Laws. Historical sources using delicta will typically reflect the older territorial rule.
