Definition
Magna Charta (also spelled Magna Carta) is the great charter of English liberties granted by King John at Runnymede on June 15, 1215, under compulsion from his barons. It is regarded as the foundational document of English constitutional liberty and one of the primary ancestors of modern due process and rule-of-law principles.
The charter was not a creation of new rights so much as a formal declaration and confirmation of existing liberties and constraints on royal power. It operated as a compact between the Crown and the barons, extracted by force rather than freely given. Its immediate scope was narrower than its later reputation suggests — many provisions addressed feudal tenure obligations and baronial grievances that have since become irrelevant — but several chapters survive as living constitutional principles.
Key provisions that shaped subsequent legal history include the prohibition on imprisonment, exile, or destruction of a free man except by lawful judgment of his peers or by the law of the land (the forerunner of due process); the principle that justice shall not be sold, denied, or delayed; and limits on the Crown's ability to levy arbitrary taxation.
The charter was confirmed and re-enacted multiple times. The version that entered the permanent English statute book is 9 Henry III (1225). By 25 Edward I (1297), it was formally recognized as part of the common law, with provisions requiring that copies be read aloud in churches twice yearly.

Common Language
Modern common usage (Wiktionary): Uncommon spelling variant of Magna Carta; a fundamental constitutional document guaranteeing rights and privileges.
Historical common usage (Webster's 1913): The great charter obtained by the English barons from King John in 1215; also the charter of Henry III; hence, any fundamental constitution guaranteeing rights and privileges.
The common-language definition captures the broad cultural symbol but obscures two legally important points. First, the legal sources are careful to identify which version of the charter is operative — the 1215 original, the 1216 or 1217 reissues, or the 1225 version under Henry III that became statute. Researchers who treat these as interchangeable will find discrepancies among sources. Second, Bouvier's pointed correction is worth holding: the charter was "almost exclusively for the benefit of" the barons at the time of its grant, not the general population. The broad libertarian reading is largely a product of later, especially seventeenth-century, reinterpretation.

Common Confusion
MAGNA CHARTA vs. MAGNA CARTA: The two spellings refer to the same document. "Charta" is the older Latin form and predominates in early English legal writing and the historical dictionaries in this corpus. "Carta" became the standard modern spelling. Researchers encountering historical sources should expect "Charta" and treat both as equivalent.
MAGNA CHARTA (1215 original) vs. THE OPERATIVE STATUTE (9 Henry III, 1225): The 1215 document was annulled by Pope Innocent III within months of its grant. The version that entered English law as statute is the 1225 reissue under Henry III. Rapalje & Lawrence flag this directly: "The charter now in force is the Statute 9 Henry III." Historical sources that cite Magna Charta without specifying a version may be referring to different texts, and the chapter numbering does not always align across versions.

Core Elements
The document's legal significance rests on several structural features that shaped later constitutional development:
1. LAWFUL JUDGMENT / LAW OF THE LAND: Chapter 39 of the 1215 charter (Chapter 29 in the 1225 version) prohibits imprisonment, dispossession, exile, or destruction of a free man except "by the lawful judgment of his peers or by the law of the land." This clause is the direct textual ancestor of due process of law in both English and American constitutional tradition.
2. ACCESS TO JUSTICE: The charter declares that justice shall not be sold, denied, or delayed — a principle directed at the Angevin practice of charging fees for judicial writs and favorable rulings.
3. LIMITS ON ARBITRARY TAXATION: Certain levies required common counsel of the realm, anticipating later parliamentary control over taxation.
4. FEUDAL PROVISIONS (historically superseded): Many chapters regulated wardship, relief, dower, and other feudal incidents. These provisions were the immediate concern of the barons who extracted the charter and are now of purely historical interest.

Recognized Forms
/ SUBTYPES
MAGNA CHARTA (1215): The original grant at Runnymede. Annulled by papal bull later the same year. Historically significant but not the operative legal text.
REISSUES OF 1216 AND 1217: Issued during Henry III's minority following John's death. The 1217 reissue was accompanied by the Charter of the Forest, which addressed forest law grievances separately.
MAGNA CHARTA (1225) — 9 HENRY III: The definitive statutory version. This is the text referenced when English and American sources cite Magna Charta as law. Confirmed by Edward I in 1297 and enrolled among the statutes.

Why It Matters in Research
Structural pattern: This term demands the historical-evolution pattern. Magna Charta is one of the most cited and least precisely cited documents in the legal corpus. Several research traps recur.
VERSION CONFUSION IN HISTORICAL SOURCES: Coke, Blackstone, and the legal dictionaries drawing on them frequently cite Magna Charta without specifying which version. Because chapter numbering differs between the 1215 and 1225 texts, a reference to "Chapter 29" in one source may not correspond to the same provision as "Chapter 29" in another. Researchers should identify which text the source is working from before accepting a chapter citation.
SEVENTEENTH-CENTURY REINTERPRETATION: The broad libertarian reading of Magna Charta — the version that shaped American constitutional thought — is substantially a construction of the early seventeenth century, particularly Sir Edward Coke's Institutes. Coke read the "law of the land" clause as encompassing common-law procedural protections far beyond what the original barons intended. This interpretive move was enormously influential but is an interpolation, not a straightforward reading of the 1215 text. Any corpus source that treats Magna Charta as a general charter of popular liberty is likely working within Coke's framework, not the original document.
AMERICAN CONSTITUTIONAL CONNECTION: "Due process of law" in the Fifth and Fourteenth Amendments traces its textual lineage directly to the "law of the land" clause. American courts frequently cited Magna Charta in early due process litigation. Researchers tracing due process doctrine will encounter Magna Charta citations in nineteenth-century American cases and need to understand they are engaging with Coke's reading, filtered through colonial charters, rather than medieval English feudal law.
CORPUS CONNECTIONS: Entries on due process, law of the land, and trial by jury in this corpus all trace back to Magna Charta as a common root. The Charter of the Forest is a related document that historically accompanied the 1217 reissue and addressed rights in royal forests — occasionally cited alongside Magna Charta in historical sources but rarely treated as part of the same text.

Historical Dictionary Support
The five source dictionaries are in broad agreement on the factual description — date, location, grantor — but diverge on characterization and emphasis in ways that are legally instructive.
Black's (both editions) presents Magna Charta as "justly regarded as the foundation of English constitutional liberty," leading with the document's elevated reputation. This reflects the dominant Whig historical reading.
Anderson's agrees in calling it "the principal guaranty of English liberties" but is careful to add that it "contained few new grants" and was "declaratory of the grounds upon which the fundamental law rested" — a substantively different claim. If the charter was declaratory rather than constitutive, it confirms pre-existing rights rather than creating them. This distinction matters for understanding how English courts and commentators used the document.
Bouvier's offers the most critically precise account, noting the charter was "really a compact between the king and his barons, and almost exclusively for the benefit of the latter." This corrective is valuable precisely because it cuts against the broader popular mythology. Bouvier also specifies June 19 as the date (Anderson's agrees), while Black's gives June 15. The discrepancy reflects uncertainty in the historical record about whether the date refers to the sealing, the delivery, or another event; researchers should not treat either date as definitive for all purposes.
Rapalje & Lawrence contribute the most practically useful detail for corpus researchers: the identification of the operative statutory version as 9 Henry III, and the note (attributed to Coke) that the charter was confirmed by parliament more than thirty times. Coke's count has been questioned by modern historians, but its presence in the legal dictionary tradition shows how deeply Coke's reading shaped the common-law understanding of the document.
None of the historical dictionaries adequately addresses the seventeenth-century interpretive transformation or distinguishes clearly between what the 1215 text said and what Coke said it meant. Researchers should treat the historical dictionary definitions as reflecting the received Cokean tradition rather than independent medieval scholarship.

Jurisdictional Note
In England, Magna Charta's operative provisions were gradually superseded or incorporated into statute and constitutional convention. In the United States, the document was never directly enacted but shaped colonial charters, state constitutions, and ultimately the federal Bill of Rights, particularly through the due process clauses. American courts in the nineteenth century cited it as authority for due process protections with a frequency that has since declined as doctrine developed its own domestic body of precedent.
