Definition
A Latin term from feudal and civil law meaning ascendants — that is, persons in the direct line of ancestry above a given individual, such as parents, grandparents, and great-grandparents. The term functions both as a noun identifying a class of relatives and as part of a foundational maxim governing succession.
In feudal law, *ascendentes* appears principally in the rule *ascendentes non succedunt* — ascendants do not succeed — establishing that in the feudal inheritance scheme, property did not pass upward to ancestors but only downward to descendants or laterally to collateral heirs. In civil law usage, the same class of persons is rendered *adscendentes*, reflecting a variant spelling found in the Digest.
Why It Matters in Research
The practical significance of *ascendentes* lies almost entirely in the maxim it anchors: *ascendentes non succedunt*. Researchers encountering this phrase in feudal tenure disputes, inheritance treatises, or early common law commentary should understand it as a structural rule of feudal succession, not a general principle of inheritance law. The feudal rationale was that a fief descended through the bloodline to those who would bear military service obligations — a feudal tenant's parent had already held the property at one remove; the system directed land downward to those who would carry the duty forward.
The spelling divergence — *ascendentes* in feudal sources versus *adscendentes* in the Digest — is a minor but useful signal when tracing a source's provenance. The civil law spelling with *ad-* appears in Digest 23.2.68, which concerns marriage prohibitions rather than succession directly; researchers should not conflate the civil law use of the term (classifying relatives for purposes of prohibited degrees of marriage) with the feudal succession rule. The term does double duty across two distinct legal frameworks.
Corpus researchers reading English feudal treatises from the medieval and early modern periods will find *ascendentes* largely as a term of art quoted from the Libri Feudorum (Feudal Book, Book 2, Title 50), the standard compilation of Lombard feudal custom that became a touchstone for European feudal law commentary. Its appearance in an English source is often a marker that the author is drawing on continental feudal doctrine rather than purely common law inheritance principles.
Historical Dictionary Support
Burrill is the primary available source and captures the essentials efficiently: the feudal law context, the maxim, the civil law variant spelling, and the dual citations to the Libri Feudorum and the Digest. There is little to elaborate upon from a single-source basis, but the entry rewards unpacking. The citation to Feud. Lib. 2, tit. 50 grounds the maxim in the Libri Feudorum, the foundational text of feudal tenure doctrine widely glossed by medieval jurists and integrated into Bracton-era English legal writing. The Digest reference (23.2.68) establishes that civilian lawyers used the *adscendentes* form when cataloguing degrees of relationship for marriage law — a different analytical purpose than succession.
Historical dictionaries generally treat *ascendentes* as a vocabulary entry rather than a doctrinal one, leaving the substantive content of the maxim to succession and feudal law treatises. Researchers wanting the full doctrinal weight of *ascendentes non succedunt* will need to move beyond dictionary sources into feudal law commentaries.
Jurisdictional Note
The maxim *ascendentes non succedunt* was a feudal doctrine and had limited direct application in English common law, where different inheritance rules governed. Civilian and mixed-law jurisdictions influenced by Roman law used *adscendentes* as a classification term in family and succession law. Modern legal systems have largely abolished feudal inheritance structures, and the term survives primarily in historical and comparative legal scholarship.
