Why is the fall of the Western Roman Empire considered an ideal case study in historical causation rather than a simple story of military defeat?

Model answer: Because the collapse resulted from multiple interacting factors — political fragmentation, fiscal crisis, pandemic, military overextension, and demographic change — whose relative weight historians continue to debate. No single cause is sufficient, and different evidence supports different causal stories, illustrating how historians weigh evidence, construct arguments, and contest interpretations.
The ongoing scholarly debate (Gibbon vs. Heather vs. Goffart vs. Ward-Perkins) demonstrates that even well-documented historical events resist monocausal explanation. This makes the topic valuable for teaching historical thinking: students must evaluate evidence, consider what would confirm or refute a given explanation, and recognize that 'what happened' and 'why it happened' are distinct questions.
