Paper 1 style: Structured Questions (Section A — Core Content)

On the real paper, Section A offers 8 questions (4 on this option, 4 on the Nineteenth Century option) and candidates answer two, plus one further question from Section B on a Depth Study (not covered by this Core Content resource). Practise any two of the four questions below; each is worth 20 marks, split across three parts.

Question 1: The Paris Peace Settlement

(a) Describe the roles of the “Big Three” negotiators at the Paris Peace Conference. [4]

(b) Explain two reasons why Georges Clemenceau wanted a harsh settlement imposed on Germany. [6]

(c) ‘The Treaty of Versailles was fair to Germany.’ How far do you agree? [10]

Worked answer

(a) Woodrow Wilson (USA) sought a settlement based on his Fourteen Points and self-determination. David Lloyd George (Britain) sought terms firm enough to satisfy public opinion but not so harsh as to destabilise Europe. Georges Clemenceau (France) sought to permanently weaken Germany’s ability to threaten France again. [4]

(b) Any two: France had suffered enormous casualties and physical destruction on its own territory, unlike Britain or the USA, giving Clemenceau strong domestic pressure to secure compensation and security. Clemenceau wanted to permanently weaken Germany’s ability to threaten France again, given France had been invaded by Germany twice in living memory (1870 and 1914). He sought territorial and financial concessions, such as reparations and the loss of territory like Alsace-Lorraine, to both punish Germany and rebuild France. [6]

(c) Case for fairness: Germany was held responsible under the “war guilt” clause partly because its own actions (invading Belgium and France) had triggered the wider war, and some historians argue the terms were less harsh than Germany itself had previously imposed on defeated Russia at Brest-Litovsk in 1918. Case for unfairness: the loss of territory, the size of reparations, and the military restrictions arguably went beyond what was needed for security and instead created lasting German resentment that later fed into support for extremist politics. Judgement: a strong answer weighs both cases explicitly and reaches an explicit conclusion, rather than simply describing the terms — for example, concluding that the treaty’s basic principle (holding a defeated aggressor to account) was defensible, but that its practical severity went beyond what security alone required. [10] (Marks for weighing both cases with evidence and reaching an explicit conclusion.)

Question 2: The League of Nations

(a) Describe two named aims of the League of Nations. [4]

(b) Explain two reasons for the League of Nations’ failure to prevent aggression in the 1930s. [6]

(c) ‘The League of Nations was doomed to fail from its creation.’ How far do you agree with reference to its structure and its early successes? [10]

Worked answer

(a) Any two: to maintain world peace and prevent future war; to promote international cooperation; to improve social and economic conditions worldwide; to encourage disarmament. [4]

(b) Any two: the League had no permanent armed force of its own, so it depended on member states voluntarily providing troops or sanctions, which they were often reluctant to do. Major powers were absent or left — the USA never joined, and Japan and Germany (both announcing withdrawal in 1933) and Italy (1937) left the League during the 1930s, weakening its authority and reach. The requirement for unanimous Council decisions made swift, decisive action against aggression very difficult to achieve. [6]

(c) Case for “doomed from the start”: structural weaknesses — no armed force, the absence of major powers, and the unanimity requirement — were built in from the League’s creation and were never resolved. Case against: the League had genuine early successes in some border and humanitarian disputes during the 1920s, suggesting failure was not inevitable but resulted from specific later decisions, such as the response to the Manchurian and Abyssinian crises. Judgement: a strong answer concludes with an explicit view on which case is stronger, using specific evidence — for example, arguing that the structural weaknesses made failure likely once a major power acted aggressively, but the League’s actual collapse still required Britain and France’s specific choice not to confront Japan and Italy in the 1930s. [10] (Marks for weighing both cases with evidence and reaching an explicit conclusion.)

Question 3: Hitler’s Foreign Policy and the Outbreak of War

(a) Describe two aspects of Hitler’s foreign policy in the 1930s that increased the risk of war. [4]

(b) Explain how the policy of appeasement encouraged Hitler to take greater risks. [6]

(c) ‘Hitler’s foreign policy was entirely to blame for the outbreak of war in 1939.’ How far do you agree, considering other contributing causes? [10]

Worked answer

(a) Any two: rearmament in open violation of the Treaty of Versailles, signalling clear intent to challenge the post-war settlement by force if necessary. Territorial expansion — remilitarising the Rhineland, the Anschluss with Austria, and the annexation of the Sudetenland — repeatedly tested whether Britain and France would resist. [4]

(b) Each time Hitler tested Britain and France’s resolve, they responded with concessions rather than confrontation, which Hitler read as evidence the Western powers lacked the will to enforce the post-war settlement by force; this pattern of unresisted escalation encouraged him to take progressively larger risks, culminating in the invasion of Poland once he judged, wrongly, that Britain and France would again fail to act decisively. [6]

(c) Case for Hitler’s responsibility: his foreign policy aims and repeated territorial actions through the 1930s directly and deliberately challenged the post-war settlement. Case for other causes: appeasement by Britain and France, the Treaty of Versailles’s own resentment-generating terms, and the League of Nations’ weakness all contributed to an environment in which aggression went unchecked. Judgement: a strong answer weighs Hitler’s own actions against these wider contributing factors before reaching a conclusion — for example, arguing that Hitler’s ambitions were the driving force, but that the international context determined how far he was able to go before he was finally resisted. [10] (Marks for weighing Hitler’s responsibility against other factors with evidence, and reaching an explicit conclusion.)

Question 4: The Cold War and US Containment

(a) Describe two reasons why the wartime alliance between the USSR and the Western powers broke down after 1945. [4]

(b) Explain why the Korean War (1950–53) was an example of the USA’s policy of containment. [6]

(c) ‘The USA was effective in containing the spread of communism during the Cold War.’ How far do you agree, with reference to Korea, Cuba and Vietnam? [10]

Worked answer

(a) Any two: ideological differences between the capitalist Western democracies and the communist USSR resurfaced once the shared enemy (Nazi Germany) was defeated, removing the main reason for cooperation. Disagreements over the future of Eastern Europe, particularly Poland and the wider Soviet sphere of influence, produced mutual distrust about the other side’s long-term intentions. [4]

(b) When North Korean forces, backed by the USSR and later China, invaded South Korea in 1950, the USA led a United Nations force to reverse the invasion, treating the defence of South Korea as a direct test of its policy of stopping the spread of communism beyond its existing borders rather than allowing further territory to fall under communist control without resistance. [6]

(c) Korea: containment succeeded in its core aim — South Korea remained non-communist after the war ended in 1953, even though the war ended in stalemate near the original border rather than in a decisive victory. Cuba: containment failed to prevent Fidel Castro’s communist revolution from succeeding in 1959, just off the US coast, though the USA’s firm response during the 1962 missile crisis did succeed in forcing the removal of Soviet missiles from the island. Vietnam: containment ultimately failed — despite prolonged US military involvement, South Vietnam fell to the communist North in 1975, at enormous cost to the USA in both lives and domestic political support. Judgement: a strong answer reaches an explicit judgement about overall effectiveness rather than simply describing each case separately — for example, arguing that the USA was effective at preventing the direct territorial spread of communism in some cases (Korea, and arguably Cuba after 1962) but far less effective at reversing or preventing it once a communist movement already had strong indigenous local support (Cuba’s revolution itself, and Vietnam), suggesting containment worked better as a military response to invasion than as a strategy against internal revolution. [10] (Marks for using specific, accurate evidence from all three named case studies and reaching an explicit, comparative judgement.)

Paper 2 style: Document Question (one question, five parts, 40 marks)

The real Paper 2 sets one document question, on a single prescribed Core Content topic, with up to seven sources. This illustrative question uses three.

Illustrative topic: The Cuban Missile Crisis, 1962

Source A — from a US government briefing note, October 1962: “Aerial reconnaissance has confirmed the presence of Soviet medium-range ballistic missile sites under construction in Cuba, within striking distance of major American cities.”

Source B — from a Soviet government statement, October 1962: “The weapons supplied to Cuba are purely defensive, intended to protect a sovereign nation against the threat of invasion, as recent events at the Bay of Pigs demonstrate.”

Source C — from a modern historian: “Both leaders privately wanted a way out of a crisis neither had fully intended to create — the eventual deal, a public Soviet withdrawal in exchange for a public US pledge not to invade Cuba and a secret promise to remove American missiles from Turkey, let both sides claim victory at home.”

(a) According to Source A, what had US reconnaissance discovered in Cuba? [4]

(b) Why do you think the Soviet government in Source B described the missiles as “purely defensive”? [6]

(c) How far do Sources A and B agree about the purpose of the missiles in Cuba? [8]

(d) How useful is Source C to a historian studying how the crisis was resolved? [7]

(e) ‘The Cuban Missile Crisis shows that neither superpower actually wanted war.’ How far do the sources support this view? [15]

Worked answer

(a) According to Source A, US aerial reconnaissance had confirmed Soviet medium-range ballistic missile sites under construction in Cuba, within striking distance of major American cities. [4]

(b) The Soviet government likely used “purely defensive” to present the missiles as a reasonable response to a genuine security threat (referencing the US-backed Bay of Pigs invasion attempt of 1961) rather than as an aggressive escalation, both to justify the deployment to international opinion and to avoid appearing to have deliberately provoked a crisis with the USA. [6]

(c) The two sources disagree fundamentally about purpose, though they may agree on the underlying fact that missiles were present: Source A frames the missiles purely in terms of the threat they pose to American cities, while Source B frames the same missiles as a defensive response to a prior American threat against Cuba. Each source reflects its own government’s position rather than offering a neutral account, so their disagreement is best understood as a difference in justification and framing rather than a disagreement about the missiles’ existence. [8]

(d) Source C is useful because it offers a historian’s later, informed account of the crisis’s actual resolution, including details (the secret Turkey missile withdrawal) that were not made public at the time and that neither Source A nor B could have revealed; its usefulness for understanding how the crisis was resolved is high, though it is less useful for understanding the two governments’ contemporary public positions, which Sources A and B capture more directly. [7]

(e) Source C directly supports the claim, stating both leaders “privately wanted a way out” and describing a negotiated compromise that let both sides avoid war while each claimed success domestically. Sources A and B, read on their own, present the crisis in more confrontational terms — an American security threat and a Soviet defensive justification — but neither source describes any intention to actually launch an attack; both are focused on justifying a position rather than announcing an intention to fight. Own knowledge supports the claim further: the crisis was resolved through negotiation rather than military conflict, and the compromise Source C describes (a public US pledge not to invade Cuba, alongside a secretly agreed withdrawal of American missiles from Turkey) shows both sides were willing to make concessions specifically in order to avoid war. A well-supported judgement should conclude that, despite the confrontational public language visible in Sources A and B, the sources together — especially once Source C’s account of the actual, negotiated outcome is included — support the view that neither superpower wanted the crisis to end in war. [15] (Marks for accurate use of all three sources with attention to provenance, own knowledge, and a sustained judgement.)

Where marks are usually lost

• Describing Hitler’s actions in isolation without weighing appeasement and the League’s weakness as contributing factors — a “how far” question requires balance.
• Naming League of Nations weaknesses without linking them to a specific 1930s outcome.
• Discussing US containment of communism using the Marshall Plan or NATO rather than the three named case studies (Korea, Cuba, Vietnam) this key question is actually examined against.
• On the document question, repeating what a source says without weighing its provenance (who wrote it, when, and why).
