Purpose and description
Enable an agent to identify, attribute and assess an event or circumstance invoked as a reason for war while keeping the asserted justification distinct from underlying motives and any assessment of legality.
A casus belli is an event, act, or circumstance invoked by a political authority as grounds for going to war, whether or not it actually caused the war or provides a legally valid justification.
It can be Reconstruct who invoked which circumstance as grounds for which resort to war.; Separate incident evidence, responsibility attribution and the argument for war into independently assessable propositions.; Compare rival accounts of the same claimed casus belli without merging their positions.; Track whether a conditional trigger occurred and whether the invoking actor subsequently maintained, revised or abandoned its claim.; Identify missing evidence and route questions of legal validity or historical causation to the appropriate neighbouring models..
Distinguishing features
An event becomes a casus belli in this model through an attributable connection to grounds for war; a serious incident alone does not establish that relationship.
A background cause explains why conflict developed, whereas a casus belli identifies a reason invoked for resorting to war; the same circumstance can occupy both roles.
Calling something a pretext adds a judgment about the relationship between stated grounds and actual motives; that judgment requires separate evidence.
A treaty activation condition concerns an obligation or entitlement under an agreement; it becomes relevant here when an actor invokes it as grounds for entering war.
Recognition as a casus belli does not establish that the alleged event occurred, that an adversary caused it or that the resulting use of force was lawful.
Scope
+ Events and circumstances alleged to provide grounds for war
+ Actors invoking those grounds, their intended audiences and their stated adversaries
+ The argument connecting an alleged grievance to a proposed or actual resort to war
+ Evidence supporting or contesting the triggering allegation
+ Changes in the claim, its reception and its role in decisions over time
- The complete causal history of a war
- Military operations, targeting and campaign planning
- Comprehensive legal adjudication of a resort to force
- Treaty obligations and alliance activation conditions as independent objects
- War aims and peace settlements beyond their relationship to the asserted grounds
- Game mechanics using casus belli as a rule or resource
Characteristics
- Usage sense
- Actor-declared grounds; contemporary attributed grounds; retrospective analytical label; disputed sense Separates an actor's own justification from terminology supplied by observers or later historians.
- Invoking actor and authority
- Actor linked to speaker, institution, decision-making authority and represented constituency A private demand for war has a different role from a government's adopted position.
- Alleged triggering circumstance
- Claim linked to a discrete incident, continuing condition, anticipated event or cumulative pattern Identifies what allegedly makes war warranted without assuming the allegation is true.
- Responsibility attribution
- Accused actor, alleged conduct, attribution mechanism and supporting or opposing evidence The occurrence of an incident and the responsibility assigned for it can have different evidentiary support.
- Invocation stage
- Conditional warning; asserted grounds; adopted decision rationale; retrospectively asserted; withdrawn; superseded Distinguishes a threatened consequence from a rationale actually used in a war decision.
- Justificatory register
- Legal; moral; security; treaty-based; religious; dynastic; mixed; other actor-specified register Preserves the standards the actor appeals to instead of imposing one universal test.
- Evidence assessment
- Unassessed; supported; contested; contradicted; indeterminate, separately for each proposition and as of a stated date Prevents confidence in one part of the allegation from being transferred to the entire justification.
- Audience reception
- Audience linked to endorsement, rejection, qualified acceptance, silence or unknown position, with date and source A claim can persuade one audience while being rejected by another.
- Invocation-to-action interval
- Elapsed time in days, with date precision and uncertainty recorded Helps distinguish advance warnings, immediate justifications and explanations introduced after action began.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 16 findings · 29 questions.
Meaning and invocation Establishes the sense of casus belli being used and the attributable act of treating something as grounds for war.
The model must distinguish a declared justification from an observer's classification of an incident.
Sense and instance
Defines what counts as an instance under the usage being recorded.
Grounds rather than incident alone
Record whether the term denotes an alleged triggering circumstance, an articulated justification or an analyst's relationship between the two.
- Whose definition of casus belli is being used, and does it require an explicit invocation? definition
- What evidence distinguishes this instance from an incident later associated with war only through chronology? boundary
Speaker and standing
Locates the invocation within the institutions and constituencies of the actor concerned.
Authority to invoke
Identify the speaker, represented actor and status of the statement within the decision to threaten or wage war.
- Which statement or record establishes who invoked these grounds, when and to whom? provenance
- Did the relevant decision-making authority adopt the claim, or did it remain an individual or factional position? boundary
Trigger and responsibility Separates what allegedly happened from the claim that a particular adversary bears responsibility.
A casus belli may depend on disputed facts, uncertain attribution or a condition that has not yet occurred.
Trigger specification
Makes the alleged incident, condition or threshold precise enough to investigate.
Alleged threshold for war
Capture the circumstance and any stated condition under which it would become grounds for war.
- What specific event, continuing condition or anticipated act is alleged to warrant war? definition
- If the invocation is conditional or cumulative, what observable threshold does the actor say must be crossed? measurement
Attribution and evidence
Examines the evidentiary steps from an alleged occurrence to adversary responsibility.
Separate occurrence from blame
Assess evidence for the occurrence, its characterization and its attribution independently.
- Which sources support or contradict the alleged occurrence, and which independently address responsibility? provenance
- What connects the accused actor to the incident: direct action, authorization, support, omission or another alleged relationship? definition
- Which unresolved evidentiary gap could materially change the responsibility assessment? boundary
Argument for war Reconstructs how the invoking actor moves from a grievance to a claimed warrant for war.
Even a well-supported allegation does not explain, by itself, why the actor presents war as an appropriate response.
Normative bridge
Identifies the rules, values or security claims used to connect the trigger to war.
Claimed warrant
Preserve the actor's justificatory reasoning and distinguish it from assessments supplied by other parties.
- What rule, obligation, value or security necessity is invoked to make this circumstance grounds for war? definition
- Which parts of that reasoning are explicitly stated, and which have been reconstructed by an observer? provenance
- Which claims require a separate legal or ethical assessment before an agent can treat them as established? action
Response and remedy
Relates the stated grounds to the action demanded, threatened or taken.
Scope of the claimed response
Record the proposed resort to war and any stated conditions for avoiding or ending it.
- What initiation, entry or escalation of war does the actor claim this ground warrants? boundary
- What remedy, concession or change of circumstances would the actor accept as removing the stated grounds? action
Contestation and motives Preserves disputes over the claim's credibility, acceptance and relationship to wider motives.
A model of casus belli must represent disagreement without equating an official account, an accusation of pretext or audience acceptance with truth.
Audience and counterclaim
Records how relevant parties respond to specific parts of the justification.
Located disagreement
Attribute acceptance and rejection to named audiences and identify the proposition each response concerns.
- Which domestic institutions, allies, adversaries or other audiences accepted or rejected the claim? provenance
- Does each disagreement concern the event, responsibility, the asserted warrant or the proposed response? boundary
Stated grounds and other motives
Keeps the invoked reason distinct from hypotheses about why war was desired or chosen.
Pretext as an assessed claim
Treat allegations of pretext, fabrication or opportunistic use as claims requiring attribution and evidence.
- Who characterizes the casus belli as sincere, opportunistic, fabricated or pretextual, and on what evidence? provenance
- Does the evidence demonstrate deception about the stated grounds, or only the presence of additional motives? boundary
Trajectory and decision use Tracks the claim through warnings, war decisions, revisions and later reassessment.
The timing and persistence of an invocation affect whether it explains a decision, threatens a future response or retrospectively justifies an action.
Invocation timeline
Orders the alleged trigger, available evidence, public claims and relevant decisions.
Contemporaneous and retrospective grounds
Record what was asserted and knowable at each stage without importing later discoveries into earlier assessments.
- When were the trigger, invocation and relevant war decision recorded, and how precise are those dates? measurement
- Which grounds appeared before the decision, and which were introduced or substantially revised afterward? provenance
Revision and use limits
Identifies when an assessment must change and what conclusions it can support.
Reassessment triggers
Maintain the current status of the invocation and explicit limits on conclusions drawn from it.
- Has the invoking actor withdrawn, replaced or maintained the grounds after concessions, contradictory evidence or changed circumstances? provenance
- What new evidence or authoritative decision would require the agent to revise its assessment? action
- Which conclusions remain unsupported, including legality, actual motive and causal importance in the decision for war? boundary
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

Neighbouring kinds and how to tell them apart
Recalled without web access and unsourced; every item is a lead to verify.
- cause of war - A cause helps explain why war occurred; a casus belli is invoked as grounds for undertaking it.
- pretext for war - A pretext implies an ostensible or misleading rationale; calling something a casus belli does not by itself establish insincerity.
- trigger of war - A trigger precipitates hostilities; a casus belli supplies an asserted justification, although one incident can serve both roles.
- declaration of war - A declaration formally announces a state of war; a casus belli is the ground offered for it.
- casus foederis - A casus foederis is a circumstance activating treaty obligations, especially alliance commitments; a casus belli concerns grounds for war.
- jus ad bellum - Jus ad bellum comprises rules governing resort to force; a casus belli is a particular asserted ground assessed against applicable rules.

What the second pass must settle
- Which reference traditions require an explicit invocation, and which also call an uninvoked occasion or retrospective explanation a casus belli?
- How should the concept extend to non-state actors and undeclared hostilities without treating every justification for violence as grounds for war?
- Which historical and cultural differences in acceptable grounds for war require distinct interpretive treatment within this single registry entry?
- What evidentiary standards should distinguish a knowingly fabricated pretext from an erroneous but sincerely held allegation?
- How should several overlapping grounds be grouped when an actor adds, abandons or substitutes justifications during the same conflict?
