Definition
Confirmatio Chartarum (Latin: "Confirmation of the Charters") is the name given to the English statute enacted in the 25th year of Edward I's reign (1297), which confirmed and gave formal legal force to Magna Carta and the Charter of the Forest. The statute declared the Great Charter to be part of the common law of England, voided all judgments rendered contrary to its provisions, ordered copies sent to all cathedral churches to be read aloud twice yearly before the people, and directed that sentences of excommunication be regularly pronounced against those who violated its terms by word, deed, or counsel. The statute also extended to personal property the same fundamental protections that Magna Carta had established for personal liberty.
Common Confusion
Confirmatio Chartarum is sometimes conflated with Magna Carta itself, but the two are distinct instruments separated by more than eighty years. Magna Carta (1215, reissued with modifications in 1216, 1217, and 1225) was the original grant. Confirmatio Chartarum (1297) was the statutory confirmation that gave the 1225 version of Magna Carta its definitive common law status. When historical sources refer to Magna Carta "as law," they often mean the version as confirmed and constituted by the 1297 statute, not the 1215 original. Researchers should also not confuse this statute with the separately named Charter of the Forest or with later Parliamentary confirmations of Magna Carta, of which there were many throughout the medieval period.
Why It Matters in Research
Researchers working in English constitutional history or the common law foundations of American civil liberties will encounter Confirmatio Chartarum as a critical link in the chain connecting Magna Carta (1215) to its ongoing legal force. The statute matters for several reasons that historical dictionary entries tend to understate.
First, Confirmatio Chartarum is not merely a restatement of Magna Carta — it is the moment at which the Great Charter was formally absorbed into the common law as enforceable doctrine rather than existing as a feudal grant subject to royal revocation. Researchers who treat Magna Carta as self-executing from 1215 forward miss this intervening step.
Second, the statute's extension of protection to personal property (as distinguished from Magna Carta's focus on personal liberty) is significant and is noted only in Rapalje & Lawrence among the shelf sources. This dimension is relevant to research on the development of property rights in English and early American law.
Third, the ecclesiastical enforcement mechanism — excommunication for violators — reflects a medieval legal reality that vanishes in later constitutional commentary. Researchers reading nineteenth-century treatises that quote or summarize the statute may find this provision treated as ceremonial or omitted entirely, creating a distorted picture of how the statute was understood to operate in its own era.
Fourth, because the statute was sealed at Ghent while Edward I was on campaign in Flanders (as Rapalje & Lawrence notes), some historical sources catalog it under variant dates or locations. Researchers using continental European archives or cross-referencing English parliamentary rolls should be alert to this geographic circumstance.
Fifth, Confirmatio Chartarum appears in American founding-era legal literature as evidence that constitutional limits on government are themselves a species of common law tradition, not a purely American innovation. This framing surfaces in debates over the reception of English common law in the new states and is worth tracking for researchers in early American legal history.
Historical Dictionary Support
The four shelf sources are in substantial agreement on the core content of the statute. Black's (both editions) and Bouvier offer nearly identical text, likely drawing from the same underlying source. All four identify the statute as 25 Edw. I and describe the key provisions: confirmation of the Great Charter as common law, the voiding of contrary judgments, distribution of copies to cathedral churches, twice-yearly public readings, and excommunication of violators.
Rapalje & Lawrence adds two points the others omit: the precise dating and sealing circumstances (November 5th, at Ghent, under the king's great seal, as shown by a memorandum on the roll) and, more substantively, the characterization of the statute as giving to personal property the security that Magna Carta gave to personal liberty — attributed to Barrington's Observations on the Statutes. This comparative framing is genuinely useful and represents the most analytical contribution among the shelf sources.
None of the shelf sources discuss the statute's reception in American law or its role in the intellectual history of constitutionalism, reflecting the limits of nineteenth-century English-focused legal dictionaries for researchers working on transatlantic legal history.
