Definition
In old European law, a drungus was a band or troop of soldiers — a distinct military unit. The Latin phrase used across all historical sources is *globus militum*, meaning literally a "ball" or "mass" of soldiers, suggesting a closely grouped fighting unit rather than a formation defined by strict numerical count. The term appears in medieval military and legal contexts as a descriptor for an organized body of armed men operating under a common command.

Why It Matters in Research
This term is purely of antiquarian and historical interest. Researchers will encounter drungus almost exclusively in:
1. **Medieval legal and military treatises** — particularly works touching on feudal military obligation, garrison law, or the organization of levied forces in early European kingdoms. The term belongs to the vocabulary of late Roman and post-Roman military administration that persisted into early medieval legal usage.
2. **Spelman's Glossarium** — all three source dictionaries cite Spelman as the authority, meaning Henry Spelman's *Glossarium Archaiologicum* (various editions, 17th century) is the primary scholarly anchor for this term. Researchers tracing this entry back to its root should consult Spelman directly rather than relying solely on the dictionary entries, which are uniformly derivative of that single source.
3. **Latin military texts** — the Latin dictionary tradition (citing Vegetius, *Epitoma Rei Militaris* 3.16, and Vopiscus, *Vita Probi* 19) confirms the term's use in late Latin military writing. Vegetius in particular was widely read throughout the medieval period and influenced the legal framing of military organization in feudal contexts. These classical citations give drungus a documented lineage that pre-dates its appearance in medieval European law.
4. **Trap for researchers**: The near-uniform copying across Black's (1st and 2nd editions) and Burrill's — all tracing to Spelman — means these three entries provide no independent corroboration. They are the same source appearing three times. Do not treat their agreement as triangulated verification. Any deeper research on this term must go to Spelman and the classical military sources directly.
The term has no modern legal application. Its research value is genealogical: understanding the vocabulary through which early European law described military organization, collective force, and the legal status of armed groups acting in concert.

Historical Dictionary Support
Black's Law Dictionary (1st ed.), Black's Law Dictionary (2nd ed.), and Burrill's Law Dictionary are in complete agreement — not surprisingly, given that all three draw on the same single citation to Spelman. The definitions are functionally identical, differing only in minor word order. None of the three entries expand on the legal consequences or uses of the drungus, its relationship to other military units, chain of command, or the legal obligations it created or operated under.
Burrill's formatting note — the accent mark over the first syllable (*drún-gus*, implied by the typographic convention of his dictionary) — is the only editorial addition across any of the three entries, and it is a pronunciation artifact without substantive legal content.
What the historical dictionaries do not address: the drungus's relationship to the *droungos* of Byzantine military law, a parallel term denoting a comparable unit in eastern imperial organization. Researchers working on Byzantine legal or military texts should be aware that the western Latin *drungus* and the Byzantine Greek *droungos* (δροῦγγος) are cognate terms reflecting the same late-antique military vocabulary, but the institutional structures they describe diverged significantly between western and eastern practice.

Jurisdictional Note
No modern jurisdiction employs this term. Its historical usage was pan-European in the sense that late Roman and early medieval military vocabulary was broadly shared, but specific application would have varied by region and period within medieval European law.
