Definition
In French and feudal law, a suzereign (also suzerain) is the immediate vassal of the king — a crown vassal. The term designates a lord who holds land or a fief directly from the sovereign, and who in turn may have vassals of his own beneath him. The suzereign occupies the top tier of the feudal pyramid below the king himself, distinguished from inferior lords who hold their tenure through an intermediate lord rather than directly from the crown.
The term carries a secondary sense in the law of nations: a state that exercises paramount authority over a dependent or semi-sovereign state. In this public-law usage, the dominant state is the suzerain and the subordinate state exists in a condition of suzerainty — possessing some attributes of sovereignty while remaining subject to the overriding control of the suzerain power.

Common Language
Modern common usage (Wiktionary): A sovereign or state having suzerainty over another; a feudal lord to whom fealty is due.
Historical common usage (Webster's 1913): A superior lord, to whom fealty is due; especially, a feudatory sovereign; a ruler or nation that has some control over an autonomous nation.
The common usage here is unusually close to the legal meaning, but the gap worth noting is one of precision: in ordinary usage, "suzerain" loosely describes any dominant ruler or state. In strict feudal legal usage, the suzereign is specifically the immediate vassal of the king — not any lord above another, but one who holds directly of the crown. The public-law sense (dominant state over semi-sovereign state) is a later extension and appears rarely in the historical dictionaries.

Common Confusion
SUZEREIGN vs. SOVEREIGN: These terms are frequently conflated in historical sources and in general reading, but they occupy distinct positions in feudal theory. The sovereign is the king — the apex of the feudal hierarchy, holding from no one. The suzereign holds directly from the sovereign. A suzereign may exercise enormous power and may appear sovereign in local practice, but is legally subordinate. The near-identical spelling in French variants compounds the confusion in older manuscripts.
SUZEREIGN vs. MESNE LORD: A mesne lord also occupies a middle position in the feudal chain but does not hold directly from the crown. The suzereign's defining characteristic is that direct crown tenure — the absence of any intermediate lord between the holder and the king. A mesne lord, by contrast, interposes between the crown and inferior tenants.

Why It Matters in Research
Researchers will encounter this term almost exclusively in one of two contexts: (1) English and French feudal land law, particularly in materials concerning tenure, homage, and fealty; or (2) nineteenth-century international law materials addressing colonial and imperial relationships between states.
In feudal law sources, the spelling is inconsistent. "Suzerain," "suzereign," "souverain," and variants appear interchangeably across law French and early English legal texts. A corpus search limited to one spelling will miss relevant material. Butler's Co. Litt. Note 77, lib. 3 — cited by Burrill — is the primary treatise anchor for the feudal sense; researchers tracing the doctrinal history of crown vassalage should begin there.
The public-law sense (dominant state over dependent state) expanded significantly in nineteenth-century usage as European powers formalized colonial relationships. This later usage is largely absent from the historical law dictionaries covered here, all of which treat the term as a feudal relic. Researchers working on international law materials from 1850 onward should not rely on these dictionary entries as a guide to suzerainty in the state-relations sense — that body of doctrine developed separately and is better traced through international law treatises of the period.
Cross-corpus connections: The term appears in proximity to TENURE, HOMAGE, FEALTY, LIEGE, and MESNE in feudal law materials. In international law materials, it connects to SOVEREIGNTY, PROTECTORATE, and DEPENDENT STATE.

Historical Dictionary Support
All three source dictionaries — Black's (1st ed.), Black's (2nd ed.), and Burrill's — give essentially identical definitions: the immediate vassal of the king; a crown vassal. The agreement is complete and the definitions are terse. None of the three sources develops the term at length, suggesting that by the time these dictionaries were compiled, suzereign was treated as a settled historical term requiring only identification rather than analysis.
Burrill alone provides a citation, directing readers to Butler's Co. Litt. Note 77, lib. 3. This is the only substantive bibliographic anchor in the historical record for this term and represents the most useful starting point for deeper feudal law research.
What the historical dictionaries miss entirely: the international law sense of suzerainty — a dominant state's authority over a semi-sovereign dependent state — was in active use during the period when both editions of Black's were published. The omission likely reflects the dictionaries' orientation toward domestic common law rather than public international law.

Jurisdictional Note
The feudal sense of suzereign is a historical concept with no active domestic legal application in U.S. or modern English law. The international law sense of suzerainty retains theoretical relevance in discussions of state sovereignty and dependent territories, but no major jurisdiction employs it as an operative legal category in contemporary doctrine.
