Placing a unit in context means fixing it on a timeline and naming what came before, what happened during and what followed after. It appears in almost every international relations answer, because a cause must come before its effect.
This is the first skill in Core option B study pathways. If chronology is a general weak spot, chronology and historical context goes deeper.
How do you build a useful timeline?
- Choose a start and end. For a unit on the League of Nations, 1919 to 1939 is a sensible frame.
- Pick anchor events. These are dated, documented events that nobody disputes, such as a treaty signing.
- Add before and after layers. Write what led into each anchor and what followed it.
- Mark the type of each entry. Use E for event, T for treaty or agreement and R for a reaction. Reactions are viewpoints, so keep them separate from events.
- Say the gap. Note how long passed between linked entries. Two months and two years invite different explanations.
Worked example: the Manchurian crisis
The question: place Japan’s actions in Manchuria within the history of the League of Nations.
Anchors. The League began work in 1920. On 18 September 1931 an explosion occurred on a railway near Mukden, and Japanese forces then moved to take control of Manchuria. A League commission led by Lord Lytton reported in 1932. Japan gave notice of leaving the League in 1933.
Before: the League had a record of settling smaller disputes, such as the Aaland Islands in 1921. During: the Lytton inquiry and the Assembly debates. After: Japan’s withdrawal and, in 1935, Italy’s invasion of Abyssinia.
Timeline check. 1920, League starts. 1921, Aaland. 1931, Mukden. 1932, Lytton Report. 1933, Japan leaves. 1935, Abyssinia. The sequence shows a League that had settled smaller disputes before facing a large power in the 1930s. That is an inference from the order, so write it with a qualifier: “the sequence suggests”.
What mistake do students make?
Mistaken timeline: Cold War begins 1961 (Berlin Wall), then Truman Doctrine 1947.
The student remembered a famous event and treated it as the starting point. Doing so puts the Truman Doctrine, a documented 1947 policy statement, after the beginning. The correction is to anchor the unit with the earliest event your course names, then place later events relative to it. Ask: “Does this event belong inside my chosen frame, and where?”
Check yourself
1. Put in order: Anschluss, Rhineland remilitarised, invasion of Poland, Munich Agreement.
Show answer
Rhineland remilitarised (March 1936), Anschluss (March 1938), Munich Agreement (September 1938), invasion of Poland (1 September 1939).
2. Why should “Germany called the treaty a Diktat” be marked R, not E?
Show answer
It records how Germans reacted, which is a viewpoint. The signing is the event. Marking R stops you using a reaction as proof of what the terms did.
3. Which unit would you frame as 1945 to 1949 if your question is about the early Cold War?
Show answer
Cold War origins, with anchors such as the Truman Doctrine (1947), the Marshall Plan announcement (1947), the Berlin blockade (1948 to 1949) and NATO (1949).
