Definition
Charte Libertatum (also rendered Charta Libertatum) is the Latin designation for the collective body of foundational English charters of liberty, referring specifically to Magna Carta (the Great Charter of 1215 and its successors) and the Carta de Foresta (Charter of the Forest, 1217). Together, these two instruments formed the constitutional framework that medieval English kings were periodically required to confirm, and they are treated in historical legal sources as companion documents rather than independent instruments.
As a term of art, Charte Libertatum does not refer to a single document but to the pair: Magna Carta governed the liberties of free men and the limits of royal power over persons and property; the Carta de Foresta governed royal claims over forest lands and the rights of those who lived within or adjacent to them. Both were issued under the seal of the Crown and were subject to periodic reissuance and confirmation throughout the thirteenth and fourteenth centuries.
Common Confusion
Charte Libertatum is frequently encountered as though it were a synonym for Magna Carta alone. It is not. The term encompasses both Magna Carta and the Carta de Foresta as a unit. Researchers encountering the phrase in medieval or early modern sources should resist the assumption that only Magna Carta is intended. The Carta de Foresta, though less celebrated in modern constitutional memory, was an independent instrument of comparable contemporary importance, regulating the scope of royal forest jurisdiction and protecting commoners' access to forest resources. Conflating the pair with Magna Carta alone distorts both the history and the legal content of the combined grant.
Why It Matters in Research
The primary research risk here is terminological compression. Medieval and early modern legal writers routinely used Charte Libertatum as a collective noun, but later editors, abridgers, and commentators sometimes collapsed the reference to mean only Magna Carta. A researcher reading a seventeenth-century argument invoking the "liberties confirmed by the charters" must attend carefully to whether both instruments are in play, particularly when forest rights, common of pasture, or estovers are at issue.
Chronologically, the two charters traveled together through Parliamentary confirmation, especially in the fourteenth century. Statutes of Confirmation routinely paired them, and writs issued to enforce one often referenced the other. Law Mind corpus researchers working in the medieval parliamentary record or the Year Books will encounter the paired citation frequently enough that treating them as a single entry point is practically necessary.
The charters also have different textual histories. Magna Carta exists in multiple versions (1215, 1216, 1217, 1225, and the enrolled version of 1297), and researchers must identify which recension a source is citing. The Carta de Foresta went through fewer revisions but was subject to its own pattern of interpretive controversy, particularly around the definition of "forest" and the scope of royal purveyance. Variant readings across these recensions occasionally produce different legal outcomes, and historical dictionaries often treat only the 1215 text as authoritative when the 1225 version is the one that entered the statute roll and carried legal force in English courts.
For American legal history, the relevance is mostly foundational and rhetorical: colonial charters, state constitutional arguments, and Founding-era invocations of natural liberty frequently cited Magna Carta as though it were an unbroken constitutional tradition. In that context, Charte Libertatum functions as a shorthand for the entire inherited framework of English liberty, not a technical term of American positive law.
Historical Dictionary Support
Black's Law Dictionary states directly that Charte Libertatum refers to Magna Carta and the Charta de Foresta, which is the correct and complete identification. Black's also records the maxim Chartarum super fidem, mortuis testibus, ad patriam de necessitudine recurrendum est — "the witnesses being dead, the truth of charters must of necessity be referred to the country, i.e., a jury" — drawn from Coke on Littleton. This maxim, though not definitionally part of Charte Libertatum itself, signals how historical English law treated the evidentiary status of solemn instruments when oral testimony was unavailable, a point of real interpretive weight in disputes over charter-based rights.
Rapalje & Lawrence contributes the related maxim Charta de non ente non valet — "a charter concerning a thing not in existence avails not" — also drawn from Coke on Littleton. Again, this is a general maxim of charter interpretation rather than a feature specific to Charte Libertatum, but Rapalje & Lawrence's placement of it in proximity to these terms reflects the broader charter-law context in which the term operated. Neither source provides extended analysis; both treat the entry as a reference point rather than a developed discussion.
What the historical dictionaries collectively miss is the textual plurality problem: neither Black's nor Rapalje & Lawrence distinguishes among the multiple recensions of Magna Carta or addresses the interpretive consequences of that plurality. For research purposes, the dictionaries should be treated as entry points only.
Jurisdictional Note
Charte Libertatum is a term of English legal history with no direct operative force in any modern American jurisdiction. Its relevance in American research is historical and constitutional-theoretical. English law treats Magna Carta (the 1297 enrolled version) as a statute still formally on the books, though most of its operative clauses have been repealed.
