Definition
SIEGE has two distinct senses in legal research contexts:
1. (Military/International Law) A prolonged military operation in which an armed force surrounds and blockades a city, fortress, or fortified position with the intent to compel surrender through force, starvation, or attrition. Siege warfare carries significant legal consequences under the laws of war, governing the rights and duties of besieging forces, the protections owed to civilian populations, and the rules governing bombardment, capitulation, and surrender.
2. (French/Civil Law; Historical) A seat or place of official authority. In French maritime and admiralty law, siège referred to the seat or tribunal of an admiralty court — the designated place where admiralty jurisdiction was formally exercised. Burrill records the usage dans tous les sièges de l'Amirauté (in all the seats of the admiralty), drawn from the Ordonnance de la Marine (1681).

Common Language
Modern common usage (Wiktionary): A prolonged military assault or blockade of a city or fortress with intent to conquer by force or attrition; also informally, any prolonged period of difficulty or assault.
Historical common usage (Webster's 1913): A seat, especially a royal seat or throne; also a place or position of authority. The military sense coexisted with the older seating sense in early modern English. Webster's notes the word as largely obsolete in the seat meaning by 1913.
The gap matters for legal research. In ordinary modern usage, siege is purely military. In French and civil law sources, particularly admiralty materials, siège is a seat of jurisdiction — a court's place of authority — not a military operation. A researcher encountering siège in a French legal text or an admiralty ordinance who reads it as military context will misread the document entirely.

Common Confusion
The English word siege and the French siège appear identical in transliterated contexts and share a common etymological root, but they do not carry the same primary legal meaning. English legal usage of siege in historical sources almost always refers to military operations or, archaically, to a seat of authority. French civil and admiralty law usage of siège almost always refers to a court's seat or official tribunal location. Do not assume military context when reading French-language admiralty or ecclesiastical sources.
Siege should also be distinguished from blockade. A blockade is a naval operation cutting off maritime access to a port or coastline; a siege typically denotes a land or combined land-and-naval encirclement of a fixed fortification or city. The distinction carries legal weight under the laws of war and prize law, where the rules governing each differ.

Why It Matters in Research
Researchers working in the Law Mind corpus will encounter siege in two entirely separate bodies of material, and recognizing the divide is essential.
In admiralty and French civil law materials, siège functions as a jurisdictional term. The Ordonnance de la Marine (1681) — Colbert's great codification of French maritime law — organizes admiralty authority around designated sièges. When Burrill cites dans tous les sièges de l'Amirauté, he is pointing to the geographic distribution of admiralty judicial seats. Any researcher tracing French admiralty jurisdiction, prize court authority, or the reach of marine ordinances into colonial or comparative law contexts needs to treat siège as a term of jurisdictional organization, not military action.
In laws-of-war and international law materials, siege is a term of operational military law. The rights of besieging forces, the treatment of a besieged population, the legal effect of capitulation, and the status of property taken during a siege all attract distinct rules. Historical sources on the laws of war — Grotius, Vattel, Wheaton — address siege conditions extensively. Researchers tracing humanitarian law, the development of the laws of armed conflict, or prize and capture law should track siege alongside terms like bombardment, capitulation, surrender, and military occupation.
A trap in historical sources: early English legal texts sometimes use siege in the archaic seat sense (a throne, a place of dignity) with no military meaning at all. Shakespeare's usage — "the very siege of justice" — means the seat or bench of justice. Researchers encountering this sense in pre-eighteenth-century English legal or literary sources should not read military content into it.

Historical Dictionary Support
Burrill's entry is narrow but precise, treating siège solely as a French admiralty term meaning seat or tribunal location, with a single citation to the Ordonnance de la Marine. Burrill does not address the military sense at all, reflecting the dictionary's primary focus on civil and admiralty law vocabulary rather than laws-of-war terminology.
Webster's 1913 preserves the older English sense of siege as a seat of authority — throne, place of dignity, position — noting it as obsolete by 1913 in that meaning. The military sense had fully displaced the seating sense in ordinary English by the nineteenth century, which is why Burrill's French entry would have seemed somewhat distinctive to English-speaking readers even then.
No major English legal dictionary in the historical corpus (Burrill, Black, Bouvier) develops siege as a military-legal term with technical elements, which reflects a gap: the laws of war were treated more extensively in international law treatises than in legal dictionaries. Researchers should not conclude from dictionary silence that siege lacked legal significance in the laws-of-war tradition — that significance is simply housed elsewhere in the corpus.

Jurisdictional Note
The French siège as a seat of admiralty jurisdiction is specific to the French civil law and admiralty tradition and its successor systems. In English admiralty law, the equivalent concept is expressed through different vocabulary (court, session, jurisdiction). Researchers comparing French and English admiralty materials should not assume structural equivalence simply because both systems used a seat-based organizational concept.
