What the Core Study is really asking

HSC Modern History Core Study (Power and Authority in the Modern World 1919-1946) is the only compulsory study area in the course. It is examined with source-based questions worth 25 marks, and it is the section that produces the widest spread of student marks. Strong responses cite specific evidence, name specific historians, and engage critically with the sources rather than describing them.

The Core Study has four focus areas, all examinable. NESA can write a Section I question on any of them.

Focus 1: The peace and the rise of dictatorships

The Treaty of Versailles (1919)

Imposed on Germany at the end of WWI. Key terms.

War guilt (Article 231). Germany accepted sole responsibility for the war.
Reparations. Initially set at 132 billion gold marks (1921). Wrecked the German economy through the 1920s.
Territorial losses. Alsace-Lorraine to France; the Polish Corridor and Danzig lost; all overseas colonies stripped; Rhineland demilitarised.
Military restrictions. Army capped at 100,000; no air force; no submarines; six battleships.

The treaty became the unifying grievance for nationalist movements across Germany. Hitler campaigned explicitly to overturn it.

Italy and the rise of Mussolini

Italy entered WWI on the Allied side but felt cheated at Versailles (the "mutilated victory"). Post-war economic chaos, factory occupations, and fear of communism opened space for Benito Mussolini's Fascists. The March on Rome (October 1922) led King Victor Emmanuel III to appoint Mussolini Prime Minister. By 1925-1926, Mussolini had dismantled parliamentary democracy and installed a one-party state.

The USSR and the rise of Stalin

After Lenin's death (January 1924), a succession struggle pitted Stalin against Trotsky. Stalin consolidated power by 1928-1929 through control of party machinery (as General Secretary), the doctrine of "Socialism in One Country," and tactical alliances with Bukharin and others before turning on them. By 1934, Stalin was unchallenged. The Great Purges (1936-1938) eliminated rivals (Zinoviev, Kamenev, Bukharin, the senior Red Army officer corps) through show trials and execution.

Focus 2: Nazi Germany 1933-1939

This is the most heavily examined focus in the Core Study.

Consolidation of power, 1933-1934

Hitler was appointed Chancellor on 30 January 1933 by President Hindenburg, leading a coalition government. Within 18 months he had transformed Germany into a one-party dictatorship.

Reichstag Fire (27 February 1933) and the Reichstag Fire Decree suspended civil liberties.
Enabling Act (24 March 1933) gave Hitler authority to enact laws without Reichstag approval. Passed with Catholic Centre Party support after intimidation of the SPD.
Gleichschaltung (1933-1935). Trade unions banned; SPD outlawed; all other parties dissolved or merged into the NSDAP. The Law against the Formation of New Parties (July 1933) made the NSDAP the only legal party.
Night of the Long Knives (30 June 1934). Hitler ordered the SS to murder SA leader Ernst Rohm and other rivals (including former Chancellor Schleicher). This secured army loyalty and removed a populist faction within the Nazi movement.
Death of Hindenburg (2 August 1934). Hitler merged the Presidency with the Chancellorship and required the army to swear personal loyalty to him as Fuhrer.

The Nazi state in operation

Hitler's regime was not a single chain of command. Structuralist historians (Kershaw, Mommsen) describe a "polycratic" state in which competing agencies (SS, party, ministries, regional Gauleiters) competed for influence by anticipating Hitler's wishes. Kershaw's phrase "working towards the Fuhrer" captures how subordinates radicalised policy on their own initiative.

Racial policy

Nuremberg Laws (September 1935). Reich Citizenship Law stripped Jews of citizenship. Law for the Protection of German Blood banned intermarriage and sexual relations between Jews and Germans.
Kristallnacht (9-10 November 1938). SA and SS-coordinated pogrom. 91 Jews killed, 267 synagogues burned, 7,500 Jewish businesses destroyed. Jewish community fined 1 billion Reichsmarks.
Forced emigration (1933-1938). Roughly 250,000 of Germany's 525,000 Jews emigrated, often after surrendering most of their property.

Opposition and resistance

Opposition existed but was suppressed. The Communist Party (KPD) and SPD were destroyed by 1933. The White Rose (Sophie and Hans Scholl, executed 1943) and the July 1944 plot (Stauffenberg) are the famous examples. Many religious leaders (Bonhoeffer, Niemoller) opposed elements of Nazi rule. The Edelweiss Pirates and Swing Youth represented youth dissent. None came close to overthrowing the regime.

Focus 3: The search for peace and security

The interwar attempt to prevent another general war collapsed by 1939.

The League of Nations

Founded by the Treaty of Versailles. Aimed to provide collective security through arbitration and economic sanctions. Major failures.

Manchuria (1931-1933). Japan invaded Manchuria. The League's Lytton Report condemned the invasion. Japan left the League.
Abyssinia (1935-1936). Italy invaded Abyssinia (Ethiopia). The League imposed limited sanctions but excluded oil. Italy completed conquest. The League's authority was finished.
Rhineland (March 1936). Hitler remilitarised the Rhineland in violation of Versailles. France and Britain did not respond.

Appeasement

Britain (Neville Chamberlain) and France pursued appeasement, hoping to satisfy Germany's grievances and avoid war. Key moments.

Anschluss (March 1938). Germany annexed Austria.
Munich Agreement (September 1938). Britain and France allowed Germany to annex the Sudetenland from Czechoslovakia. Chamberlain returned with "peace for our time."
March 1939. Germany occupied the rest of Czechoslovakia, ending the case for appeasement.
Nazi-Soviet Pact (23 August 1939). Ribbentrop-Molotov non-aggression pact with secret protocols dividing Eastern Europe.
Invasion of Poland (1 September 1939). Britain and France declared war on 3 September.

Focus 4: The conduct of WWII and the post-war settlement

Major phases

1939-1941. German Blitzkrieg conquers Poland, Denmark, Norway, the Low Countries, France. Battle of Britain (1940). Operation Barbarossa (June 1941) opens the Eastern Front.
1941-1942. Pearl Harbor (7 December 1941) brings the US into the war. Japanese expansion across South-East Asia and the Pacific.
1942-1943 turning points. Stalingrad (Aug 1942 to Feb 1943), El Alamein (October-November 1942), Midway (June 1942).
1944-1945. D-Day (6 June 1944) opens the Western Front in Europe. Soviet advance from the East. Surrender of Germany (8 May 1945). US bombing of Hiroshima (6 August 1945) and Nagasaki (9 August 1945). Japanese surrender (15 August 1945).

The post-war settlement

Yalta (February 1945) and Potsdam (July-August 1945). Allied leaders agreed on the division of Germany into occupation zones, the prosecution of war criminals, and reparations. Disagreements over Eastern Europe foreshadowed the Cold War.
Nuremberg Trials (1945-1946). International Military Tribunal prosecuted 24 senior Nazis for crimes against peace, war crimes, and crimes against humanity. 12 sentenced to death. Established the precedent that "I was following orders" was not a defence.
United Nations (founded 24 October 1945). Replaced the League of Nations. Security Council (with great-power veto) addressed the structural flaw that paralysed the League.

Common Section I traps

Describing the source rather than analysing it: "Source A is a photograph showing..." earns little. Analysis means assessing perspective, purpose, reliability, and usefulness. Use the sources as evidence in a wider argument.
Ignoring the question verb: "Assess" requires a judgement. "Explain" requires causation. "To what extent" requires a degree-of-agreement. "Evaluate" requires weighing strengths and weaknesses.
Generic answers about Nazi Germany: Markers reward specific dates, named individuals, named laws, named events. Say "Enabling Act, 24 March 1933" not "a law in 1933 that gave Hitler power."
Missing historiography on the extended response: The 10-15 mark question rewards engagement with historians' interpretations. Cite Kershaw, Mommsen, Dawidowicz, or Overy where relevant.
Forgetting to cross-reference sources: Strong responses use multiple sources to corroborate or contrast. Markers explicitly reward this.

How the Core Study is examined

Section I typically contains:

Source analysis (3-4 marks). Assess the usefulness or reliability of one source. Address perspective, purpose, audience, context. About 5-6 minutes.
Short structured response (5-7 marks). Use sources and own knowledge to explain or describe an aspect of the focus area. About 8-10 minutes.
Extended response (10-15 marks). Use sources and own knowledge to analyse, evaluate, or assess a proposition. Engage with historiography. About 15-22 minutes.

Total Section I budget: 45 minutes. The most common mark-loss is over-writing the short response and running out of time on the extended response.

Practice strategy

For HSC Modern History Core Study:

Term 2-3 of Year 12. Build a one-page summary per focus area. Memorise 20-30 specific pieces of evidence (dates, names, statistics).
Term 3-4. Weekly source analysis. NESA past papers from 2019 onwards use the current syllabus. Practise the source-analysis verbs.
Term 4. 4-6 full Section I responses under timed 45-minute conditions. Mark against the NESA marking guide.

See our HSC Modern History practice questions for prompts modelled on NESA past papers.

Worked examples

Worked example 1: source analysis of the Nuremberg Laws (15 September 1935)

Question: "Assess the usefulness of the Reich Citizenship Law and the Law for the Protection of German Blood and German Honour (Nuremberg, 15 September 1935) for a historian investigating Nazi racial policy in the period 1933-1939."

OPA: Origin: two statutes passed unanimously by the Reichstag at the Nazi Party rally in Nuremberg, 15 September 1935, drafted by Interior Ministry officials (Wilhelm Stuckart, Bernhard Loesener) under pressure from radical party agitation through the summer of 1935. Purpose: codify the second-class legal status of German Jews, channel street violence into law, and supply juridical cover for further radicalisation. Audience: domestic (party radicals seeking action, conservative bureaucrats demanding "order"), and international (a regime aware of foreign press scrutiny in the year before the Berlin Olympics).
Usefulness: Highly useful as evidence of the legalistic phase of Nazi anti-Semitism. The texts permit close reading of the regime's racial categories ("Reich citizen" versus "subject"; "full Jew", "Mischling first and second degree") and show the Interior Ministry's effort to delimit the November pogrom dynamic.
Reliability: Reliable as evidence of formal legal policy; misleading as a measure of implementation. The supplementary decree of 14 November 1935 reveals that core definitions were unsettled at promulgation. Corroborate with the SD's January 1937 internal report on Jewish emigration, with Victor Klemperer's diary (I Will Bear Witness, entries September-October 1935) for received experience, and contrast with Kershaw's reading (Hitler 1889-1936: Hubris, 1998) that the laws were a partial brake on radical violence rather than a master plan.

Worked example 2: model body paragraph on Nazi consolidation

Prompt: "Evaluate the significance of the Night of the Long Knives (30 June 1934) for the consolidation of Nazi power."

The Night of the Long Knives on 30 June 1934 was the hinge at which the Nazi regime ceased to be a coalition and became a personal dictatorship. SS units, acting on Hitler's verbal authority, murdered Ernst Rohm and the SA leadership at Bad Wiessee along with former Chancellor Kurt von Schleicher, Gustav von Kahr, and roughly 85 named victims (the number rises to about 200 in revisionist counts). The killings simultaneously neutralised the SA's threat to the Reichswehr, propitiated the conservative elites whose support Hitler still needed, and demonstrated that violence outside law was now a permitted instrument of state. Hitler's Reichstag speech of 13 July 1934 retrospectively legalised the murders as "supreme justice," and the Law concerning Measures of State Self-Defence (3 July 1934) gave statutory cover. Ian Kershaw (Hitler 1889-1936: Hubris, 1998) reads the episode as the moment Hitler "crossed the Rubicon" into unconstrained charismatic rule, while Richard Evans (The Coming of the Third Reich, 2003) stresses the army's silence as the structural enabler. The Night was therefore not merely a purge but the founding act of Fuhrer absolutism.

Annotation.

Topic sentence makes a single judgement ("hinge") that answers the verb "evaluate."
Specific perpetrators, locations and victim counts ground the paragraph in NESA-style detail.
The 13 July Reichstag speech and the 3 July law are paired so the paragraph shows legal as well as violent consolidation.
Kershaw is named, dated, and his thesis summarised in one clause, then complemented (not duplicated) by Evans on structural enablers.
The closing sentence reframes the judgement in the prompt's vocabulary ("consolidation").
Word count 208, inside the 180-220 target and leaving room for three further paragraphs.

Worked example 3: historiography integration on the Nazi state

The intentionalist-structuralist debate on how Nazi policy radicalised is the most testable historiographical question in this option. Ian Kershaw (Hitler 1889-1936: Hubris, 1998; Hitler 1936-1945: Nemesis, 2000) developed the structuralist phrase "working towards the Fuhrer," arguing that subordinates anticipated Hitler's wishes and competitively radicalised policy in his name. A response can deploy this concisely: "Kershaw's structuralist account replaces a master-plan model with a polycratic dynamic, in which the Nuremberg Laws of September 1935 emerged from interaction between street agitation and bureaucratic codification rather than a long-prepared blueprint."

Set Kershaw against Robert Service or Richard Overy. Overy (The Dictators: Hitler's Germany, Stalin's Russia, 2004) defends a residual intentionalism: Hitler's ideological obsessions, present from Mein Kampf (1925-1926) onwards, set the policy direction within which subordinates improvised. A critical handling reads: "Overy's intentionalism usefully recovers the ideological frame that Kershaw's polycracy risks dissolving, though Overy concedes that the radicalisation of policy in 1938-1941 cannot be explained by intention alone." Holding the two in tension - intent plus polycratic dynamics - signals Band 6 historiographical handling.

Plan: (a) origin and Nuremberg rally context; (b) categories ("Reich citizen", "Mischling") and 14 November 1935 supplementary decree; (c) corroborate with Klemperer's diary and SD emigration data; (d) Kershaw on radicalisation. Evidence: Stuckart-Loesener drafting, Olympic 1936 international context, exclusion from civil service April 1933.
3: Thesis: League structural defects were necessary but not sufficient; great-power calculation completed the failure. Plan: (a) structural critique (US absence, unanimity, no army); (b) Manchuria 1931-33 and the Lytton Report; (c) Abyssinia 1935-36 and Hoare-Laval; (d) Rhineland March 1936 and Franco-British paralysis. Evidence: Japan's withdrawal 1933, Italian use of mustard gas, Hitler's gamble. Cite Zara Steiner (The Triumph of the Dark, 2011).
