Period Study: Causation and Contingency in a Turning Point
An essay question asks: 'Assess the significance of a single decisive battle in a historical period you have studied.' A student has chosen a battle and written: 'The battle was the turning point because after it everything changed. The sources agree it was decisive. Therefore the period after the battle was fundamentally different.' The teacher's feedback identifies three problems: (1) 'everything changed' is unfalsifiable; (2) 'the sources agree' is asserted without naming or evaluating them; (3) the essay assumes rather than demonstrates change. The student must revise the thesis into a testable claim and support it with at least two criteria of significance, while acknowledging contingency.
1. Rewrite the thesis as a testable claim and identify what evidence would falsify it.

Original: unfalsifiable - no observation could count against 'everything changed'. Revised thesis: 'The battle was significant not because it ended conflict but because it transferred X (territory, legitimacy, military initiative) to Y, and that transfer persisted in the settlement of the following decade.' Falsification conditions: the thesis fails if (a) the settlement restored the pre-battle position; (b) the transfer was reversed within a generation; (c) the same transfer occurred through other means, making the battle incidental. Why this is better: it names a specific variable (X), an agent (Y), a timeframe (the following decade), and observable consequences (the settlement). The essay can then test each. Method note: 'turning point' is a comparative claim - a turning point relative to what would otherwise have happened. The student should state the counterfactual explicitly: 'without the battle, the settlement would likely have preserved the earlier balance.' That makes the claim arguable rather than decorative.
2. The student says 'the sources agree it was decisive'. What must replace this, and how?

Replace assertion with named, evaluated sources and a distinction between fact and interpretation. Steps: (1) Name the sources and their date and standpoint - a contemporary victory monument, a later narrative historian, a hostile account. (2) Separate claims: what do they agree on (the battle occurred, the outcome), and where do they diverge (numbers, responsibility, significance)? (3) Explain divergence by purpose and access: a monument magnifies; a later historian shapes the battle into a moral lesson; a hostile source minimises. (4) Conclude that agreement on the fact of victory is not agreement on decisiveness - the latter is the historian's judgement, not the sources'. Replacement sentence: 'The sources agree on the outcome but not on its significance: the victory monument presents it as decisive, while the later narrative treats it as one episode in a longer war. The claim of decisiveness must therefore be argued from consequences, not from consensus.' This directly addresses the teacher's second criticism and demonstrates source evaluation rather than invoking it.
3. How should the essay incorporate contingency without collapsing into 'it could have gone either way'?

Contingency should be bounded and evidenced, not a general disclaimer. Three moves. (1) Identify a specific contingent factor - weather, a commander's decision, a defection, a supply failure - and show it was not structurally determined. (2) Show the counterfactual's plausibility with evidence: if the factor had gone the other way, what would probably have followed, and why? (3) Then argue that the outcome's consequences were not contingent - once the battle was lost, the settlement followed from existing structures (treaties, alliances, fiscal limits). Model phrasing: 'The outcome hinged on a contingent decision at the crisis point; had it gone otherwise, the campaign might have stalled. But the settlement that followed drew on alliances already in place, so the direction of change was structural even if the timing was contingent.' Why this is stronger: it distinguishes contingency in events from contingency in outcomes, which is exactly the distinction examiners reward. 'It could have gone either way' is a starting point; the essay must say which way, why, and what followed.
