Germany's total defeat in the spring of 1945 brought not a peace settlement but military occupation and, within four short years, partition. There was no treaty as there had been in 1919; instead four occupying powers assumed supreme authority over a devastated, starving country, and out of the breakdown of their cooperation there emerged two rival German states — a liberal-democratic Federal Republic in the west and a Soviet-aligned dictatorship in the east — that would face one another across the Iron Curtain for forty years. This lesson traces that decisive transition: the landscape of "Zero Hour", the framework of four-power occupation, the halting and ultimately abandoned attempt at denazification, the escalation of the early Cold War over reparations and currency, the confrontation of the Berlin Blockade, and the twin foundings of 1949. It asks the question that runs through the whole post-war half of this breadth study: was the division of Germany the inevitable product of irreconcilable Allied differences, or an outcome that more flexible diplomacy might have avoided?
For a breadth study running from 1918 to 1989, these four years are the hinge between the two great German experiments the course compares. The failed first democracy of Weimar and the Nazi terror state that destroyed it lie on one side; the durable second democracy of the Federal Republic, and the dictatorship of the GDR that consciously echoed features of the Nazi past, lie on the other. The democracy versus dictatorship thread that has structured the course does not end in 1945 — it begins again, in two rival forms, under foreign tutelage. Understanding how sovereignty passed to the occupiers, how their common slogans dissolved into incompatible practice, and how a temporary administrative division hardened into two permanent states is therefore the indispensable foundation for everything that follows about the rival systems of the Cold War.

This lesson belongs to Edexcel 9HI0 Paper 1, Option 1G (Route G): "Germany and West Germany, 1918–89" — a breadth study assessed by extended analytical essays (Sections A and B) and by the evaluation of historians' interpretations (Section C). In our teaching sequence it opens the post-war half of the course, following the collapse of the Nazi state and introducing the two rival systems whose contrasting fortunes dominate the rest of the Paper. We have deliberately gathered occupation, division and the twin foundings into a single lesson so that students grasp 1945 to 1949 as one continuous process — the recasting of an internal German question into a problem of the Cold War international system — rather than as a sequence of isolated episodes.
Because Paper 1 is a breadth paper, examiners reward command of change over time and judgements about the scale and durability of change. Keep asking how each step — Potsdam, Bizonia, the Marshall Plan, currency reform — narrowed the options and hardened the division, and how the settlement of 1949 shaped the two systems that followed. (For the precise assessment weightings and question wording, consult the official Edexcel specification and sample assessment materials rather than any paraphrase.)
The scale of destruction in May 1945 conditioned everything that followed. Major cities lay 50 to 80 per cent in ruins; industrial production had fallen to roughly a fifth of its 1938 level; transport, housing and finance had collapsed; and a barter-and-black-market economy replaced a worthless currency. Around twelve million ethnic Germans (the Vertriebene) fled or were expelled from eastern Europe, and hundreds of thousands died during the flight and expulsion; millions of displaced persons, former forced labourers and prisoners of war had to be repatriated or resettled. Average rations in some places fell as low as 1,000 to 1,500 calories a day, far below subsistence. And Germans were confronted, amid widespread denial and a rhetoric of their own victimhood, with the exposed scale of Nazi crimes.
Into this catastrophe the German language projected the idea of Stunde Null — "Zero Hour" — the moment of capitulation on 8 May 1945, implying a complete break with the past and a fresh start. Historians have substantially qualified the notion. Beneath the rubble much survived: industrial capacity was less comprehensively destroyed than the ruined city centres suggested; the bureaucracy, the judiciary, much of the business class and the administrative machinery persisted, often staffed by the same personnel; and attitudes formed under Nazism did not evaporate overnight. The rhetoric of a "clean slate" was psychologically and politically attractive to Germans — it implied that the new beginning owed nothing to the recent past and distanced ordinary people from complicity — but it obscured profound continuities of personnel, structures and mentalities that the occupiers would soon have to confront. Recognising this gap between the language of rupture and the reality of continuity is itself an analytical theme, connecting 1945 to the course's recurring question of how far regime change in Germany was ever as complete as it appeared — a question that runs from the "November Revolution" of 1918 to the "Zero Hour" of 1945 and on to the reckoning with the Nazi past in both post-war states.
The shape of occupied Germany was determined at a sequence of wartime conferences whose deceptive language of unity concealed widening tensions.
| Conference | Date | Key decisions |
|---|---|---|
| Tehran | November 1943 | Agreement on the second front; preliminary, inconclusive discussion of post-war Germany |
| Yalta | February 1945 | Germany to be divided into occupation zones (a French zone added); reparations discussed; free elections promised for liberated Europe |
| Potsdam | July–August 1945 | The "Four Ds" — demilitarisation, denazification, democratisation and decentralisation; reparations to be drawn chiefly from each power's own zone; the Oder–Neisse line confirmed as Poland's de facto western border and population transfers sanctioned |
By Potsdam the wartime "Big Three" had changed in composition — Roosevelt had died and Truman represented the United States, while Churchill was replaced mid-conference by Attlee — and the underlying tensions between the USSR and the Western powers were already visible. Germany was divided into four zones: an American zone (Bavaria, Hesse, northern Baden-Württemberg, the Bremen enclave); a British zone (the industrial north-west); a French zone (Rhineland-Palatinate, the southern south-west, the Saarland); and a Soviet zone (Mecklenburg, Brandenburg, Saxony, Saxony-Anhalt, Thuringia). Berlin, deep inside the Soviet zone, was itself divided into four sectors — an arrangement that would make the city the recurring flashpoint of the Cold War.
Supreme authority over Germany as a whole was vested in the Allied Control Council (ACC), established in June 1945 and composed of the four military governors. But the ACC could act only by unanimity, and the Potsdam principle that Germany should be treated "as a single economic unit" depended on a cooperation that proved unattainable. In practice each commander governed his own zone, applying common slogans in incompatible ways. The French, who had not been party to Potsdam, used their veto from the outset to block central German administrations, fearing any revival of a unified Reich on their eastern frontier. The Soviet authorities pressed reparations and social transformation in their zone, while the Western powers increasingly prioritised recovery. Four-power government effectively ended when the Soviet representative, Marshal Sokolovsky, walked out of the ACC on 20 March 1948, months before the blockade. The analytical lesson is that the machinery of joint rule was hollow almost from the start: shared institutions could not bridge divergent purposes.
No issue did more to drive the zones apart than reparations. The Soviet Union, which had borne staggering wartime losses, regarded reparations as a matter of survival and justice and dismantled and removed plant from its zone on a large scale. Potsdam had conceded that each power would draw reparations chiefly from its own zone, with the USSR additionally receiving a quota of capital equipment from the western zones in exchange for food and raw materials from the east — an exchange that quickly broke down. In May 1946 the American military governor, General Lucius Clay, halted reparations deliveries from the US zone to the Soviet zone, citing the failure to treat Germany as a single economic unit. The dispute over the "level of industry" — how much industrial capacity Germany should retain — exposed the underlying clash: a prostrate Germany suited Soviet security but threatened to make the western zones a permanent economic burden and a breeding ground for instability. Reparations thus became the practical mechanism through which the zones came to be administered separately, well before any decision in principle to divide the country.
The Allies agreed on the principle of denazification but implemented it very differently, and the onset of the Cold War steadily eroded their commitment to it. At the Nuremberg Trials (November 1945 to October 1946), the International Military Tribunal of the four powers tried twenty-one leading defendants in person (Bormann in absentia): twelve were sentenced to death (among them Göring, who took poison before he could be hanged, and Ribbentrop, Keitel and Jodl), seven were imprisoned (including Speer and Hess), and three were acquitted (Papen, Schacht and Fritzsche). The trials established the principle of individual criminal responsibility for crimes against peace, war crimes and crimes against humanity, and created a vast documentary record of Nazi criminality. Critics dismissed them as "victor's justice" applying retroactive law; defenders maintained that they set vital precedents for international law.
Below the level of the leadership, denazification was pursued zone by zone with markedly different rigour.
| Zone | Approach | Outcome |
|---|---|---|
| American | The most systematic; some 13 million questionnaires (Fragebogen) and tribunals (Spruchkammern) | Became bureaucratic and discredited; many were classified as mere "followers" (Mitläufer); the process collapsed under its own weight |
| British | More pragmatic; concentrated on removing key figures and restoring administration | Less thorough but arguably more effective at removing genuine Nazis from sensitive posts |
| French | The least committed; needed German administrators to run the zone | Minimal in practice |
| Soviet | Selective: removed Nazis from key positions while also purging political opponents and expropriating estates | Used denazification to entrench communist control; some former Nazis were recruited where politically useful |
By 1948 denazification was widely judged a failure across all zones. Most former Nazis had been reintegrated, and the imperatives of the Cold War made rehabilitation and stability more pressing to the occupiers than continued accountability. The uncomfortable continuity of personnel — judges, officials, managers and businessmen who had served the Reich and now served its successors — connects directly to the questioning of "Zero Hour": the second German democracy, like the first, would be built in part by people compromised by the regime it replaced.
The wartime alliance disintegrated rapidly as shared objectives gave way to divergent interests, and the division of Germany advanced by increments rather than through a single rupture. Each measure provoked a counter-measure, and the room for a unified settlement contracted with every step.
| Date | Step | Significance |
|---|---|---|
| Jan 1947 | Bizonia merges the US and British zones economically | Creates the economic nucleus of a future West German state |
| Jun 1947 | Marshall Plan announced; the USSR forbids its satellites to accept it | American aid to rebuild western Europe; a decisive parting of the ways |
| Feb 1948 | Communist coup in Czechoslovakia | Alarms Western opinion and accelerates plans for a separate West German state |
| 20 Mar 1948 | Sokolovsky walks out of the Allied Control Council | Ends four-power government |
| 20 Jun 1948 | Currency reform introduces the Deutsche Mark in the western zones | Triggers the Soviet response |
| 24 Jun 1948 | Berlin Blockade begins; the Airlift answers it | Coercive blockade of land access met by supply from the air |
| May 1949 | Blockade lifted; Basic Law promulgated (FRG) | Western statehood confirmed |
| Oct 1949 | German Democratic Republic founded | Eastern statehood confirmed; division institutionalised |
The single most dangerous confrontation of these years came over Berlin. When the Western Allies introduced the new Deutsche Mark in a currency reform on 20 June 1948 in their zones and the western sectors of Berlin, the USSR responded by cutting all land and water access to West Berlin from 24 June. The Western reply — the Berlin Airlift — supplied the western sectors of the city entirely by air for almost eleven months, with aircraft landing at very short intervals around the clock. The blockade and airlift demonstrated Western resolve and the credibility of the American commitment to Europe; transformed West Berliners from former enemies into symbolic Cold War allies; discredited the USSR in Western opinion; and made the division of Germany, and of Berlin, politically irreversible. It is essential to grasp that the blockade was a coercive blockade of land access, not an attempt to seize the whole city by force — both sides drew back from direct military conflict — and that it was a Soviet reaction to a Western initiative, which is central to the interpretative debate below.
Faced with the manifest impossibility of four-power agreement, the Western powers authorised the West Germans, through the "Frankfurt Documents" of July 1948, to draft a constitution. The Basic Law (Grundgesetz), drafted by a Parliamentary Council in Bonn over which Konrad Adenauer presided, was promulgated on 23 May 1949. Crucially, its authors insisted on calling it a "Basic Law" rather than a "constitution", and on its explicitly provisional character, precisely to signal that they were not abandoning reunification or conceding the permanence of division. Its key features were consciously designed to remedy the perceived failings of Weimar: a federal structure; a powerful Federal Constitutional Court; the "constructive vote of no confidence" (a chancellor could be removed only by simultaneously electing a successor); a five per cent electoral threshold to exclude splinter parties; and the entrenchment of human dignity in Article 1. The first Bundestag elections followed in August 1949, and Adenauer became the first Chancellor.
