What UPSC keeps asking about the World Wars

Forty-six questions fall into five threads. The peace settlement and the inter-war crisis are the largest; several quotations have been set twice.

1. Causes and character of the First World War (2007, 2011, 2012, 2015, 2017, 2019, 2025)

No single explanation suffices (2012) — the examiner’s own position, stated in the question.
The first “total” war (2017), what it was fought over (2015), Austria-Hungary as the new sick man (2011), its political and social consequences (2007, 2025).
Fritz Fischer’s thesis on German war aims against Christopher Clark’s sleepwalkers is the historiography to hold.

2. Versailles and the peace settlement (1987, 1990, 1993, 2000, 2001, 2006, 2011, 2016, 2023)

Nine questions — the largest thread.
“The seeds of future conflict” (2006, 2023), “an armistice for twenty years” (1993), lacking moral validity (2011), a Carthaginian peace (2016).
Keynes’s critique against Margaret MacMillan’s defence of the peacemakers is the debate to rehearse.

3. The League of Nations (1992, 1993, 1996, 2016, 2019, 2026)

“A League of notions” (2016), its ineffectiveness (2019), its failure to keep the peace (2026), and Manchuria as the crisis that decided its fate (1993).
Prepare the successes of the 1920s as well as the failures of the 1930s — a one-sided answer loses marks.

4. The inter-war crisis: Depression, New Deal and appeasement (1986, 1987, 1991, 1994, 1996, 1997, 2002, 2004, 2008, 2011, 2019, 2022, 2024)

Thirteen questions, spread across the whole period. The Depression and its consequences (1996, 2002), the New Deal (1987, 1997), the Roaring Twenties (2022), Locarno (2008).
Appeasement and Munich (2011, 2019), the Spanish Civil War as prelude (1991), the Axis (1986). A. J. P. Taylor’s Origins of the Second World War is the provocation every answer must address.

5. Japan and the Second World War (1988, 1992, 1997, 2000, 2014, 2018, 2020, 2021, 2024)

Japanese militarism (1997), the Sino-Japanese war (1992), the Russo-Japanese war and Japan’s rise (2014), the Anglo-Japanese alliance (1988).
The Second World War as a European war until December 1941 (2000, 2018 — set twice), and as a truly global conflict (2024).

How to use this topic list

Reading a question list feels like preparation and is not. Three sittings turn it into marks.

Sitting 1 — sort before you read (30 minutes)

Copy the questions above into the threads identified in the previous section.
Note which thread has gone longest without being asked — that is your priority, not the one you find most interesting.

Sitting 2 — write three answers cold (45 minutes)

Pick the most recent question from three different threads.
Seven minutes for a 10-marker, fifteen for a 20-marker. Stop when the time is up, even mid-sentence.
Mark every place you wanted a historian’s name and could not produce one.

Sitting 3 — compare, then rewrite (45 minutes)

Put your script beside the model answer for the same question.
Compare structure first: opening claim, evidence, counter-view, judgement.
Rewrite your weakest answer using that structure and no new content. Most candidates gain four to six marks from structure alone.

Two ways to prepare this optional

Two routes, depending on what is actually missing.

Frequently asked questions

Forty-six times between 1986 and 2026, appearing in every one of the last ten papers.
