Definition
In legal usage, "century" carries two distinct meanings drawn from Roman and English institutional history:
1. A grouping of one hundred persons. In Roman constitutional law, the centuriate assembly (comitia centuriata) organized citizens into voting units called centuries, originally based on property and military classification. Each century cast a single collective vote. In the English common law tradition, the analogous unit was the "hundred" — a territorial and administrative subdivision of a county — making "century" and "hundred" near-synonymous when describing the Roman system.
2. A period of one hundred years. In this sense, the term functions as a unit of time relevant to statutes of limitations, land grants, prescription periods, and historical reckonings in legal documents.

Common Language
Modern common usage (Wiktionary): A period of one hundred consecutive years; often a numbered period with conventional start and end dates. Also, an ancient Roman military unit originally of one hundred soldiers.
Historical common usage (Webster's 1913): A period of a hundred years; also a division of the Roman people formed according to property for the purpose of voting; one of sixty companies into which a Roman legion was divided.
The common meaning today is almost exclusively temporal — a hundred-year span. The legal and historical dictionaries preserve the institutional meaning — a body of one hundred persons organized for civic or military purposes — which has no currency in modern common speech. Researchers encountering "century" in early legal sources should not assume a purely temporal reference; the organizational meaning may be operative.

Recognized Forms
/SUBTYPES
Centuriate assembly (comitia centuriata): The Roman popular assembly organized by centuries, relevant to discussions of republican constitutional structure in legal history sources.
Hundred (English law): The English equivalent of the Roman century as an administrative and jurisdictional unit. County subdivisions called "hundreds" functioned as units of local governance, taxation, and legal liability. The terms are treated as functional equivalents by Black's and Bouvier's when the Roman system is being described in English legal contexts.

Why It Matters in Research
The principal research trap is anachronism: modern readers instinctively read "century" as a time period, but in sources addressing Roman law, early English constitutional history, or comparative legal systems, the word may instead denote an organized body of persons with civic or voting functions. Bouvier's and both editions of Black's foreground the institutional meaning first, which reflects its priority in the legal tradition even if not in modern speech.
For researchers working with land records, statutes, charters, or prescriptive title claims, the temporal meaning is the operative one — and precision about century boundaries (does a 100-year period run from year 1 or year 0 of a given reckoning?) can matter in calculating limitation periods or interpreting historical grants.
The term also appears in comparative law discussions where the Roman centuriate system is offered as a historical analogue to representative or suffrage structures. Researchers tracing the intellectual lineage of voting rights, proportional representation, or property-based franchise arguments may encounter "century" used descriptively in this institutional sense.
Connections within the Law Mind corpus: this term intersects with entries on HUNDRED (English administrative law), COMITIA (Roman constitutional structure), and PRESCRIPTION (time-based legal claims).

Historical Dictionary Support
All three source dictionaries — Black's (1st ed.), Black's (2nd ed.), and Bouvier's — are in close agreement. Each gives two definitions: the organizational (a body of one hundred men) and the temporal (a cycle or period of one hundred years). Both editions of Black's add the comparative note that the Romans were divided into centuries as the English were divided into hundreds, explicitly linking the Roman institution to its English common law counterpart. Bouvier's is slightly more compressed but substantively identical.
No source diverges meaningfully from the others. None of the three historical entries addresses the procedural or voting mechanics of the Roman centuriate assembly in any depth — for that level of detail, researchers must look beyond the standard legal dictionaries to Roman law treatises or legal history sources. The dictionary entries serve primarily as a reminder that the term has an institutional dimension, not as a guide to Roman constitutional procedure.
Webster's 1913 usefully adds that centuries were organized by property classification for voting purposes and that a legion contained sixty centuries — details absent from the legal dictionaries but consistent with them.

Jurisdictional Note
No modern jurisdictional variation is significant for this term. Its organizational meaning is purely historical (Roman and early English). Its temporal meaning is universal and not subject to jurisdictional divergence in any legally operative sense.
