Conflict and Peace

What you must understand

This domain spans the causes, conduct and settlement of major conflicts and the attempts to build peace. Candidates need:

  • Causes - alliance systems, militarism, imperial rivalry, nationalism, economic pressure, and immediate triggers; distinguish long-term structural causes from short-term sparks.
  • Total war - mobilisation of civilian economies, propaganda, rationing, bombing, and the blurring of combatant and civilian.
  • Peacemaking - treaties, reparations, territorial settlement, disarmament, and the tension between punitive and conciliatory approaches.
  • Institutions - the League of Nations and later the United Nations; collective security, mandates, vetoes and peacekeeping.
  • Memory and commemoration - how societies narrate war shapes later politics.

Traps in questions

  1. Trigger versus cause. An assassination is a trigger, not a structural cause; explain the conditions that made it decisive.
  2. Assuming treaties ended conflict. Settlements often created grievances that fed later conflict.
  3. Overrating institutions. The League's failures are usually structural (no enforcement, great-power absence) rather than merely bad luck.
  4. Ignoring the home front. Questions on total war expect civilian experience, not only battles.

Worked example

On the causes of a major war: structure your answer as long-term pressures (alliances, arms races, imperial competition), medium-term decisions (mobilisation plans, ultimatums), and the short-term trigger. Then evaluate which level carries most explanatory weight and why. That layered answer demonstrates causation skills rather than listing events.

Rule of thumb: separate structural causes, decisions and triggers, then argue about relative weight.
