Definition
The act of plundering, pillaging, or despoiling property; a predatory taking by force or systematic destruction. In legal usage, depredation appears in two distinct contexts:
1. French/civil law inheritance. The pillage or spoliation of a decedent's goods — the wrongful taking or wasting of property belonging to an estate, typically before lawful administration has been established.
2. General maritime and international law. The plundering of goods or territory by an enemy, pirate, or hostile force; closely associated with acts of rapine and spoliation on the high seas or in wartime.
In United States federal law, the term appears in criminal statutes prohibiting depredation against the property of the United States (see 18 U.S.C. § 1361), where it has been interpreted to mean damage, destruction, or plundering of government property.

Common Language
Modern common usage (Wiktionary): An act of consuming agricultural resources (crops, livestock), especially as plunder; a raid or predatory attack.
Historical common usage (Webster's 1913): The act of depredating, or the state of being depredated; the act of despoiling or making inroads — as, the sea often makes depredation on the land.
The common meaning tracks the legal meaning more closely than most legal terms, but a gap remains. Ordinary usage permits metaphorical and natural depredation (the sea, wildlife, time). Legal usage is confined to human agency and wrongful intent — an actor who takes, destroys, or wastes property belonging to another. A researcher should not read natural or accidental destruction into legal sources using this term.

Common Confusion
DEPREDATION vs. DEPRIVATION: These terms are occasionally confused in older printed sources due to typographic similarity and shared root suggestion. Deprivation is the act of stripping someone of a right, office, or benefit — particularly in ecclesiastical law, the removal of a clergyman from his orders or benefice (the meaning Black's 2nd ed. assigns, apparently in error, under this headword). Depredation is the plundering of property. A researcher encountering "deprivation" in ecclesiastical contexts and "depredation" in estate or maritime contexts should treat them as entirely distinct concepts.
DEPREDATION vs. DEPRIVATION (ecclesiastical): Black's Law Dictionary (2nd ed.) contains what appears to be a misplaced entry — the definition of ecclesiastical deprivation (removal of a clergyman from orders) is printed under the headword DEPREDATION. Researchers consulting that edition should treat the ecclesiastical definition as belonging to DEPRIVATION, not this term.

Why It Matters in Research
Corpus researchers should be alert to three issues.
First, source contamination. The Black's 2nd ed. entry for DEPREDATION appears to reproduce the ecclesiastical definition of DEPRIVATION — a different concept entirely. Anyone conducting historical legal research using that edition risks conflating two unrelated doctrines. Cross-check against Bouvier and Rapalje, which correctly confine depredation to the pillage of a decedent's goods in the French law context.
Second, jurisdictional layering. The term operates differently depending on the legal tradition. In French-derived civil law (relevant to Louisiana research and comparative law sources), depredation is a term of art in succession law — the wrongful spoliation of an estate. In Anglo-American common law, it appears primarily in maritime, military, and federal criminal contexts. A source using the term without identifying its legal tradition may mean something different than a source in another tradition.
Third, federal criminal usage. Modern U.S. federal jurisprudence has given the term an operative life in prosecutions under 18 U.S.C. § 1361 (destruction of government property). Courts have interpreted "depredation" in that statute to encompass intentional damage and destruction, not merely theft. Researchers working backward from modern federal cases into historical dictionary sources will find little direct guidance — the historical dictionaries do not address this usage at all.

Historical Dictionary Support
The historical dictionaries are narrow and largely in agreement. Bouvier, Rapalje & Lawrence, and Black's 1st ed. all define depredation in the French law context as the pillage of a decedent's goods. The definitions are functionally identical, suggesting common sourcing rather than independent analysis.
What the historical dictionaries miss is substantial. They do not address the maritime law usage (depredation by pirates or enemy vessels), which appears in international law treatises of the same era. They do not address the Anglo-American common law usage at all. And they entirely omit what would become the term's most significant modern legal application in U.S. federal criminal statutes.
The Bouvier entry under DEPREDATION also contains an apparent printing error — it begins mid-sentence with language that belongs to the entry for DEPOT or DÉPÔT, suggesting a compositor error in the edition used for digitization. Researchers relying on digitized Bouvier should verify the entry against a clean print edition.

Jurisdictional Note
In Louisiana, depredation in the succession law context retains relevance due to the state's civil law tradition. In federal courts, depredation is a live statutory term with an active body of case law under 18 U.S.C. § 1361. Common law jurisdictions outside the United States rarely use the term as a term of art; it appears there, if at all, in historical maritime and wartime contexts.
