Definition
A term from old English law denoting a tournament or trial of combat conducted with spears, understood as an appeal to fortune — that is, a formal submission of a dispute or question of prowess to chance or divine favor expressed through the outcome of armed contest. The term captures both the physical act (fighting with spears in organized competition) and its legal or quasi-legal character (the result carried weight as a determination by fortune).

Common Confusion
Researchers should take care not to conflate fortunium with trial by battle (judicium dei or duellum), which was a formal judicial procedure with defined procedural rules and legal effect. Fortunium, as used in the sources, emphasizes the appeal-to-fortune aspect of spear combat and appears more closely associated with the tournament tradition than with the formal judicial combat process. The two institutions overlapped in medieval practice and shared the underlying logic of fortune as arbiter, but they operated in different procedural contexts.

Why It Matters in Research
Fortunium is a narrow historical term with no modern legal application. Researchers will encounter it only in medieval English legal records, chronicles, or treatises dealing with trial by combat, chivalric regulation, or the crown's periodic prohibition of tournaments. Its relevance is contextual rather than doctrinal.
The term sits at the intersection of two distinct medieval institutions that researchers should not conflate: the tournament as aristocratic spectacle and the judicial combat (trial by battle) as a recognized legal procedure. Fortunium appears to straddle both, emphasizing the fortune-appeal element common to each. When reading medieval sources, watch for whether a writer is invoking fortunium in a purely martial sense or using it to describe something with recognized legal consequence — the distinction affects how the surrounding record should be read.
Researchers tracing royal regulation of tournaments in 13th-century England will find the term relevant to crown licensing and prohibition orders, as tournament activity was periodically controlled or banned. Matthew Paris (fl. 1200–1259), cited by Rapalje & Lawrence, is the primary chronicler source for this period and a key primary text for contextualizing the term.
Because all four source dictionaries reproduce essentially the same one-line definition, the Law Mind corpus offers limited internal depth on this term. Researchers needing substantive treatment should look outward to medieval legal history scholarship and chronicle sources rather than expecting doctrinal elaboration from legal dictionary tradition alone.

Historical Dictionary Support
Remarkable unanimity across sources: Black's (both editions), Bouvier's, and Rapalje & Lawrence each reproduce the same compact definition — a tournament or fighting with spears, framed as an appeal to fortune. There is no divergence, no elaboration, and no case law cited beyond Rapalje & Lawrence's lone reference to Matthew Paris under the year 1241.
This uniformity reflects the term's status as a historical curiosity rather than a living legal concept. Compilers included it for completeness — as evidence of how English legal vocabulary once encompassed the institutions of chivalric combat — without any expectation that practitioners would use it. What the historical dictionaries do not address is the term's relationship to the formal law of trial by battle (campus or duellum), whether fortunium carried enforceable legal consequence, or how crown courts treated the outcome of such contests. These silences are significant: they confirm that even for 19th-century legal lexicographers, fortunium was already antiquarian.
