Definition
The Great Assize was a procedural reform introduced in twelfth-century England, attributed to the reign of Henry II, that gave a defendant in a land dispute the right to elect trial by a jury of recognition rather than by trial by battle. Under the older Norman system, disputes over land title were frequently resolved through wager of battle — a formal combat between the parties or their champions. The Great Assize offered an alternative: a sworn body of twelve knights from the neighborhood would declare which party had the better right to the land. The defendant (not the claimant) held the election; once chosen, the assize displaced the combat entirely.
The Great Assize operated within the petty assizes system and was closely associated with the possessory assizes (Novel Disseisin, Mort d'Ancestor, Darrein Presentment) that Henry II introduced as part of the broader Angevin legal reforms. Together, these reforms shifted dispute resolution from private violence and ordeal toward royal court procedure and recognitional inquiry — a foundational step in the development of the English common law jury.
Common Language
Modern common usage (Wiktionary): The Last Judgment; the final divine judgment of humanity at the end of time.
Historical common usage (Webster's 1913): No distinct entry for "Great Assize" as a common term; "assize" in general usage referred to a session of a court or a fixed standard of weight or measure.
The gap here is significant. The religious sense — God's final accounting of all souls — is the phrase's primary meaning in general English and appears frequently in theological and literary texts. A researcher encountering "the Great Assize" in historical documents must read context carefully: ecclesiastical and literary sources almost certainly intend the Last Judgment, while legal and administrative sources of the Angevin period intend the procedural mechanism described above. Conflating the two produces serious misreading.
Common Confusion
The Great Assize is sometimes loosely grouped with the petty assizes (Novel Disseisin, Mort d'Ancestor) as if it were simply another assize action. It was not. The petty assizes were specific possessory actions that could be brought by a claimant and decided by a jury of recognition as a matter of right. The Great Assize was a defensive election available to the tenant in a writ of right — the most solemn form of land action, determining ultimate title rather than mere seisin. The distinction matters: the Great Assize touched the deepest layer of property right, whereas the petty assizes addressed recent dispossession.
Why It Matters in Research
Researchers working in English legal history before the nineteenth century will encounter the Great Assize primarily in two contexts: treatises on the development of the jury and secondary discussions of Angevin legal reform. Glanvill's Tractatus de Legibus et Consuetudinibus Regni Angliae (c. 1187–1189) contains the most important contemporary account and is the standard primary source.
The Bouvier entry is thin — it gestures toward Henry II's reign and the Norman recognition system but offers no procedural detail and no citation. Researchers should treat it as a signpost, not a source. The real substance lies in Glanvill and in Maitland's historical analysis.
Key research traps: First, the date of the Great Assize is genuinely uncertain; Bouvier notes this, and it remains unresolved in scholarship. Do not assume a fixed statutory date. Second, because the Great Assize fell into disuse well before the modern period — the writ of right itself was abolished in England in 1833 — it appears in later legal dictionaries (including Bouvier) largely as a historical curiosity rather than a living doctrine. Entries from the nineteenth century forward describe it in the past tense and with decreasing precision. Third, American legal sources essentially ignore the Great Assize; it never transplanted to colonial or early American procedure in recognizable form. Any American legal source invoking the term is almost certainly using it in the theological sense or as rhetorical flourish.
The connection to jury origins is the Great Assize's main doctrinal legacy. Researchers tracing the right to jury trial in civil cases — including the Seventh Amendment's preservation of that right — will find the Great Assize cited in the historical background, but as a remote ancestor rather than a direct progenitor of American practice.
Historical Dictionary Support
Bouvier's entry is the sole historical dictionary source available here, and it is notably sparse: it identifies the Great Assize as an edict of uncertain date from Henry II's reign that developed the Norman recognition system, and it points elsewhere without elaboration. This is characteristic of Bouvier's treatment of medieval English procedure generally — sufficient for identification, insufficient for analysis.
What Bouvier omits is consequential: there is no description of the election mechanism, no distinction from the petty assizes, no mention of Glanvill, and no explanation of why the reform mattered. Researchers relying on Bouvier alone will know that the term refers to something Henrician and procedural, but will not understand its function or significance. The entry is best used as a vocabulary confirmation that the term has legal rather than theological content in the source being researched.
Jurisdictional Note
The Great Assize is an English common law institution with no direct American counterpart. It is relevant in American legal research only as historical background for jury trial origins. English law abolished the writ of right (within which the Great Assize operated) in 1833 under the Real Property Limitation Act.
