Definition
Latin: "the law of the English" or "the law of the Angles." A historical term referring to the laws and customs of the West Saxons during the period of the Anglo-Saxon Heptarchy — the loose confederation of kingdoms that preceded a unified English monarchy. The jus Anglorum was not a formal written code but rather the body of customary law that governed the West Saxon people and, by preference and practical dominance, was applied more broadly across the Heptarchy's competing legal traditions. It represented the legal inheritance that West Saxon custom carried into the consolidation of England and that later commentators identified as the earliest stratum of what would eventually become the common law.
Why It Matters in Research
This term is primarily encountered in historical and jurisprudential writing rather than in operative legal documents. Researchers will find it in treatises on the origins of English common law, particularly in works examining the pre-Conquest legal order. Its significance is analytical and contextual: it marks one side of the foundational debate about whether English law descended principally from West Saxon custom, from Danelaw, from Mercian law, or from post-Conquest Norman influence.
The term functions as a periodization marker. When a historical source invokes jus Anglorum, it is almost always doing one of two things: (1) asserting the antiquity and native English character of a particular legal rule against some foreign or imposed alternative, or (2) situating a legal claim within the broader narrative of Anglo-Saxon legal continuity. Seventeenth-century common lawyers, including figures like Edward Coke, frequently appealed to the immemorial character of English custom in constitutional arguments, and jus Anglorum was part of that rhetorical vocabulary.
Because the Heptarchy was a period of overlapping and competing jurisdictions, researchers should not assume the jus Anglorum represented a single uniform body of rules. The historical record from this period is fragmentary, and claims about what West Saxon law actually required on any specific point are often contested or reconstructed from later sources. Be alert to anachronism: treatise writers of the 17th and 18th centuries sometimes projected backward, reading continuity into a record that does not fully support it.
This term does not appear in modern statutory or case law contexts. Its corpus connections are to legal history, constitutional history, and the history of jurisprudence rather than to practice materials.
Historical Dictionary Support
All four source dictionaries — Black's (1st and 2nd editions), Rapalje & Lawrence, and Bouvier's — provide nearly identical entries, each tracing to Wharton's Law Lexicon as the common upstream source. This convergence reflects the limited original research any 19th-century American legal dictionary devoted to pre-Conquest English legal history. The unanimity is less a sign of certainty than of shared dependence on a single authority.
None of the historical dictionaries engage with the substance of what the jus Anglorum actually contained, what it looked like in practice, or how it related to competing bodies of custom such as the Danelaw or Mercian law. They treat it as a label rather than as an institution. Bouvier's entry is cut off in the available source material but appears to follow the same pattern.
What the historical dictionaries miss: they do not address why the West Saxon customs held the preferred position they are said to have occupied, nor do they situate the term within the broader historiography of English legal origins. For research purposes, the dictionaries are useful only as confirmation that the term was recognized in legal literature of the 18th and 19th centuries — not as substantive guides to its content.
Jurisdictional Note
Jus Anglorum has no operative jurisdictional meaning in any modern legal system. It is a term of legal history applicable to pre-Conquest England. American legal sources that invoke it do so purely in historical or comparative argument.
