Exam scope and assessment notes
Partial 2026 course: introductory context across the twelve AS topics, with selected document workshops, not full AS or A Level preparation. All three Paper 3 alternatives have introductory context, historiography and original interpretation exercises; Italy, Stalin’s Russia, Hitler’s Germany and Britain have introductory depth pathways across their four enquiries. The USA in the late 1940s/1950s and the 1960s/1970s have introductory American depth pathways; the 1980s/early-1990s theme now introduces all four enquiries with original teaching and two longer essay workshops. All four American themes now have introductory teaching and longer essay workshops, including US foreign policy, 1944–1992. The US–Soviet theme introduces all four enquiries through thirty core lessons and two longer essay workshops. Forty-one lessons introduce all four East and Southeast Asia enquiries: eight on post-war change, nine on Korea, twelve on Vietnam and twelve on Sino-American relations. Eight lessons introduce the African independence enquiry through Ghana, Nigeria, Senegal, Kenya and comparative reasoning. Nine further lessons introduce government, economic and social challenges after independence. Thirteen further lessons introduce Cold War involvement, Chinese support, non-alignment and Pan-Africanism. Twelve further lessons introduce UN involvement in Congo and Somalia, with 1993–1995 explicitly labelled as later context beyond the theme’s 1992 endpoint. Ten lessons introduce the creation-of-Israel enquiry. Twenty further lessons introduce wars and peace efforts in 1948–1979. Seventeen further lessons introduce superpower motives, oil, American and Soviet policies and their consequences through 1991. Twenty-one further lessons introduce the Iranian Revolution, Iran–Iraq War and 1990–1991 Gulf War. All four 2026 Middle East enquiries have introductory lessons; broader reading, depth, specialist review and full assessment remain unfinished. The separate 2027–2029 requirements are not mapped by these 2026 lessons. A separately labelled revised-year orientation and Eastern Europe enquiries 7.1–7.4 introductions and South Africa enquiries 8.1–8.3 and Zimbabwe enquiry 8.4, followed by Malaya enquiry 9.1 and introductory sequences for Malaysia formation enquiry 9.2 and Indonesian nationalism enquiry 9.3, with partial preparation, revolution, 1950s challenges and New Order teaching in enquiry 9.4, are available; other revised teaching remains unfinished.

StudyForA enquiry brief · Peace, collective security and public opinion
[1] Compare different means of seeking peace and use the voluntary ballot within its questions, provenance and date. Assess influence without inventing unanimity.
1. Explain why public desire for peace did not dictate one foreign policy.
Compare after trying
Fear of another war could encourage different responses. Absolute pacifism rejected force, while collective security could involve sanctions or joint resistance. Negotiation and deterrence were therefore not automatically opposite to every wish for peace, and the means proposed need identification alongside the shared aim.
The voluntary Peace Ballot asked several questions, rather than functioning as a binding general election or statutory referendum. The July 1935 deputation records the organisers’ interpretation and advocacy. Its significance requires attention to wording and participation instead of turning one answer into a universal mandate.
Opinion could also change as aggression and international crises developed. A 1935 response cannot independently establish reactions to Munich or decisions in 1939. Public pressure mattered through particular political channels, but government information, strategy and party competition also require evidence before assigning it decisive influence.
Why this response fits
- Explains causal relationships with dated, relevant evidence.
- Qualifies the judgement through different outcomes, groups and source limits.
Peace could mean different policies
Memories of the First World War and fear of air attack made the prospect of another war deeply troubling. Desire for peace did not dictate one policy. Some people rejected military force on pacifist grounds, while others believed collective security could deter aggression or permit force under international authority. Support for the League, negotiation, economic sanctions and rearmament could combine in different ways. An account should identify the proposed mechanism rather than treat every expression of peace as identical opposition to all resistance.
The Peace Ballot of 1934–1935 was organised by voluntary campaigners and asked several questions about international policy. It was not a statutory referendum binding the government or a general election choosing MPs. Different answers concerning economic and military measures should remain separate. A high level of participation is politically significant without establishing that respondents were a random sample or that one answer measured every person’s view on all possible future crises.
Read the deputation critically
The record of the deputation to the prime minister on 23 July 1935 presents organisers’ claims about the result and its implications. It reveals what they asked government to recognise, not an independently neutral audit of all public beliefs. The organisers’ assessment of informed enthusiasm should be evaluated alongside how questions were worded, who participated and which alternatives respondents understood. Their institutional purpose does not make the record worthless, but defines the inference it can support.
Events abroad could change opinion after the ballot. Aggression, the failure of sanctions and crises in Spain or Czechoslovakia gave people new information and different choices. A 1935 response cannot automatically establish an unchanged position in 1938 or 1939. Nor does fear of bombing establish willingness to accept every concession. Compare evidence across time and distinguish avoiding immediate war from believing a particular agreement would secure lasting peace.
Assess influence and limits
Public attitudes constrained and informed politicians without mechanically determining every decision. Party competition, press, government information and military assessments also shaped debate. Identify a route of influence and test it against decisions instead of announcing that opinion alone made policy. Broader authentic reading and representative evidence remain needed to assess the relative weight of pacifism, League hopes and support for deterrence within Britain through 1939.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
Guided: Distinguish pacifism and collective security.
Give me a hint
Compare the place of force.
Compare my reasoning
- Identify rejection of force.
- Identify joint deterrence or sanctions.
- Explain possible disagreement.
A pacifist could reject military force, while a supporter of collective security might accept joint measures to deter or resist aggression. Both could seek peace through different means. Their shared aim therefore cannot establish identical policy preferences or make support for the League equivalent to rejecting every use of force.
Look for these in your work
- Separates aims and means
- Explains the difference
Independent: Explain one limit of the organisers’ 1935 deputation.
Give me a hint
Identify author and purpose.
Compare my reasoning
- Identify a case made to government.
- Check participation and questions.
- Limit the national inference.
The organisers sought government recognition of the ballot’s political meaning, so their record illuminates advocacy and interpretation. It does not independently audit every participant’s understanding or represent every nonparticipant. Questions, procedure and other evidence are needed before generalising about Britain’s public opinion.
Look for these in your work
- Evaluates provenance
- Retains participation limits
Application: Revise a fictional claim that a 1935 answer proves identical opinion about Munich in 1938.
Give me a hint
Allow time and circumstances to change.
Compare my reasoning
- Date both events.
- Identify intervening information.
- Request contemporary evidence.
A response in 1935 cannot independently establish what the same people believed about the different choices of 1938. Subsequent aggression and failed measures could alter expectations. The essay should compare contemporary reactions to Munich with the earlier ballot rather than assume that public opinion remained fixed.
Look for these in your work
- Respects chronology
- Seeks the right evidence
Common mistakes
- Equating every wish for peace with absolute pacifism
- Combining separate sanction answers
- Moving a 1935 result unchanged into 1939
