Germany's total defeat in 1945 led not to a peace settlement but to military occupation, partition, and the embedding of Germany at the very centre of the emerging Cold War. There was no peace treaty as there had been in 1919; instead, four occupying powers assumed supreme authority over a shattered country, and within four years that country had split into two rival states. For a breadth study of the German quest for political stability, this is the period in which the 'German question' — how to accommodate German power within a stable European order — was answered, provisionally, through division.
The years 1945–1949 are pivotal because they set the framework within which all subsequent German history until 1990 unfolded. The decisions taken at the wartime conferences, the failure of four-power cooperation, the economic and currency reforms of 1948, and the confrontation of the Berlin Blockade together hardened the division of Germany into the two states that would face each other across the Iron Curtain for forty years. Yet historians continue to debate whether this outcome was inevitable, and where responsibility for it lies. The central question is: was the division of Germany an inevitable consequence of irreconcilable Allied differences, or an outcome that more flexible diplomacy might have avoided?
For the breadth study, the analytical pay-off of this short period is disproportionate to its length. In just over four years, every long-running thread of the course is gathered up and re-tied. The catastrophe of total war (Lesson 6) produces the rubble landscape of 1945; the collapse of legitimate authority that had recurred since 1918 reaches its nadir under foreign military government; and the search for a stable settlement of German power, frustrated at Versailles in 1919, is renewed under utterly transformed conditions. Crucially, the actors are no longer primarily German. Sovereignty has passed to the occupiers, and the decisive choices about Germany's future are taken in Washington, Moscow and London as much as in Berlin or Bonn. Understanding occupied Germany therefore means tracing how an internal German question became a problem of the international system, and how the cumulative logic of the early Cold War converted a temporary administrative division into two permanent states.
Key Question: Did the division of Germany result from deliberate Soviet or Western design, or from the cumulative momentum of decisions — reparations, the Marshall Plan, currency reform — that neither side fully intended to be final?
Key Definition: Stunde Null ('Zero Hour') is the German term for the moment of capitulation on 8 May 1945, implying a complete break with the past and a fresh start. Historians question how accurate the concept is, since many personnel, attitudes and structures persisted beneath the surface of apparent rupture.
This lesson sits within Paper 1, Option 1L, a breadth study, in Part Two ('A Nation Brought Low? Germany, 1914–1991'). It covers the occupation of Germany, the onset of the Cold War, and the creation of the two German states — the foundation of the divided Germany that dominates the rest of the period.

The change-and-continuity threads are: the destruction and reconstruction of the German state; the tension between the Allies' shared aims (the 'Four Ds') and their divergent interests; the relationship between economic recovery and political alignment; and the recasting of the 'German question' as a Cold War problem. These threads connect the rubble of 1945 backward to the catastrophe of the Nazi years and forward to the two-states era and reunification.
The decisive chronology of these four years can be visualised as a sequence in which cooperation gives way, step by step, to confrontation:
timeline
title From Occupation to Two States, 1945–1949
May 1945 : Unconditional surrender : Four-power occupation begins
Jul–Aug 1945 : Potsdam Conference : The 'Four Ds' agreed : Zonal reparations conceded
1946 : Forced SED merger in the Soviet zone : Byrnes' Stuttgart speech signals US commitment
Jan 1947 : Bizonia merges the US and British zones
Jun 1947 : Marshall Plan announced : USSR forbids satellites to join
Feb 1948 : Communist coup in Czechoslovakia alarms the West
Jun 1948 : Currency reform introduces the Deutsche Mark : Berlin Blockade begins
1948–49 : Berlin Airlift sustains the western sectors
May 1949 : Blockade lifted : Basic Law promulgated (FRG)
Oct 1949 : German Democratic Republic founded
Read across this timeline, the pattern is one of escalation by increments rather than a single rupture: each measure provoked a counter-measure, and the room for a unified settlement contracted with every step.
The scale of destruction and dislocation in May 1945 was staggering, and it conditioned everything that followed:
| Impact | Detail |
|---|---|
| Physical destruction | Major cities 50–80 per cent destroyed; Berlin, Hamburg, Dresden, Cologne and others devastated |
| Refugees and expellees | Around 12 million ethnic Germans (Vertriebene) fled or were expelled from eastern Europe; estimates of those who died during flight and expulsion run to the hundreds of thousands and beyond |
| Population displacement | Millions of displaced persons, prisoners of war and former forced labourers had to be repatriated or resettled |
| Economic collapse | Industrial production fell to around 20 per cent of 1938 levels; transport, housing and finance were in ruins |
| Famine | Average rations in 1945–46 fell as low as 1,000–1,500 calories per day in places, far below subsistence; a black market and barter economy flourished |
| Moral crisis | Germans were confronted with the scale of Nazi crimes amid widespread denial and the rhetoric of victimhood |
The reality beneath 'Zero Hour' was thus one of acute material crisis and contested memory — conditions in which the occupying powers had to govern, feed and reconstruct a devastated society.
The notion of a complete break with the past, captured in the phrase Stunde Null, is one that historians have substantially qualified. Beneath the rubble, much survived: industrial capacity was less comprehensively destroyed than the ruined city centres suggested; the administrative machinery, the judiciary, much of the business class and the bureaucracy persisted, often staffed by the same personnel; and attitudes formed under Nazism did not evaporate overnight. The rhetoric of a 'clean slate' was attractive to Germans for psychological and political reasons — 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 important analytical and synoptic theme, connecting 1945 to the course's recurring question of how far regime change in Germany was ever as complete as it appeared.
The shape of occupied Germany was determined at a sequence of Allied conferences:
| 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 largely to be taken from each power's own zone; the Oder–Neisse line confirmed as Poland's de facto western border and the transfer of German populations 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 occupation zones:
Berlin, deep within 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 by the Berlin Declaration of June 1945 and composed of the four military governors. The ACC could act only by unanimity, and the Potsdam principle that Germany should be treated 'as a single economic unit' depended on a level of 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 to block central German administrations from the outset, fearing any revival of a unified Reich on their eastern frontier. The Soviet authorities pressed reparations claims and social transformation in their zone, while the Western powers increasingly prioritised recovery. The ACC's effective collapse was symbolised when the Soviet representative, Marshal Sokolovsky, walked out on 20 March 1948, ending four-power government months before the blockade. The lesson for an analytical answer 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, having borne staggering wartime losses, regarded reparations as a matter of survival and justice and proceeded to dismantle and remove 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 so-called 'level of industry' plan — how much industrial capacity Germany should be permitted to 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 were 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.
Twenty-one defendants were present (Bormann tried in absentia) before the International Military Tribunal of the four powers:
The trials established the principle of individual criminal responsibility for crimes against peace, war crimes and crimes against humanity, and created a 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.
| 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 wartime alliance disintegrated rapidly as shared objectives gave way to divergent interests:
When the Western Allies introduced the new Deutsche Mark in a currency reform (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 1948.
The Western response — the Berlin Airlift — supplied the western sectors entirely by air for almost eleven months; at its peak aircraft were landing around the clock at very short intervals. The blockade and airlift:
A worked example shows how a key document — the Potsdam Agreement (Protocol of the Berlin Conference, 2 August 1945) — should be evaluated rather than paraphrased.
