In 1945, Europe lay in ruins. Tens of millions were dead, cities were rubble, and economies had collapsed. Yet the Grand Alliance that had won the war was already fracturing. Within two years, former allies became Cold War rivals — and Germany became the front line.
Why did the alliance break down?: Three deep tensions destroyed wartime unity:
Ideological: the USA championed capitalism and liberal democracy; the USSR championed communism and one-party rule. Each saw the other's system as a threat to be contained.
Strategic: Stalin wanted a 'buffer zone' of friendly states in eastern Europe to protect the USSR from future invasion. The USA and Britain saw Soviet expansion into Poland and the Balkans as aggression.
Personal and political: Truman (US president from April 1945) was far more hostile to Stalin than Roosevelt had been. Churchill's 'iron curtain' speech at Fulton, Missouri (March 1946) publicly declared the divide.
Yalta (Feb 1945)
The 'Big Three' — Roosevelt, Churchill, Stalin — agreed on a post-war order: free elections in liberated Europe, a United Nations, and a divided Germany under four occupation zones. The language was deliberately vague, masking deep disagreements.
Potsdam (Jul–Aug 1945)
With Roosevelt dead and Truman in office, tensions were sharper. Leaders agreed on German reparations and de-Nazification but clashed over Poland's borders and Soviet behaviour in eastern Europe. No lasting compromise was reached.
Truman Doctrine (Mar 1947)
Truman asked Congress for aid to Greece and Turkey, which were threatened by communist insurgencies. He framed it as a global commitment to support 'free peoples' resisting communist pressure — a clear signal that the USA would actively oppose Soviet expansion.
Marshall Plan (Jun 1947)
US Secretary of State George Marshall offered economic aid to rebuild European economies. The USA feared that poverty would drive European voters towards communist parties. The USSR refused to join and pressured eastern European states to reject it.
Yalta → Potsdam → Truman Doctrine → Marshall Plan: from fragile unity to open rivalry in just two years.
Paper 3 essays on the Cold War's origins: Examiners expect you to evaluate causes, not just list them. Was ideology the main reason the alliance broke down, or was it Soviet expansionism in eastern Europe, or US economic interests? Show you can weigh these against each other. Use specific evidence: Truman's language in March 1947, Stalin's refusal of Marshall Aid for eastern Europe, and the breakdown at Potsdam over reparations.
| Factor | US/Western view | Soviet view |
|---|---|---|
| Poland's government (1945) | Free elections promised at Yalta were being suppressed | A friendly government on the USSR's border was a security necessity |
| Marshall Plan (1947) | Economic aid to rebuild democracy and prevent communist gains | An instrument of US economic imperialism and political control |
| German occupation zones | Germany must recover economically to stabilise Europe | Germany must pay reparations; a recovered Germany threatened the USSR again |

No country felt the Cold War's impact more sharply than Germany. Occupied by four powers after 1945, Germany became the central theatre of superpower competition. By 1949, it had been split into two separate states — and it would remain divided for forty years.
- Four occupation zones (1945) — Germany was divided into US, British, French, and Soviet zones of occupation. Berlin, deep inside the Soviet zone, was similarly split into four sectors.
- De-Nazification and reparations — all four powers agreed to remove Nazis from public life and extract reparations, but they disagreed sharply on how far to take both, and on how much to strip from the German economy.
- Bizone and Trizone (1946–48) — the US and British zones merged economically in 1946 (the 'Bizone'), and France joined in 1948. Western Germany was integrating economically while the Soviet zone moved in a different direction.
- Currency reform (June 1948) — the western powers introduced the new Deutschmark in their zones. Stalin saw this as a provocation — it threatened to draw his zone into the western economic orbit.
The Berlin Blockade (June 1948 – May 1949): Stalin's response to the currency reform was to blockade all road, rail, and canal routes into West Berlin. He hoped to force the western powers out of the city.
The western response was the Berlin Airlift: for eleven months, western aircraft flew supplies into the city around the clock — at its peak, one plane landed every ninety seconds. In May 1949, Stalin lifted the blockade, having failed to dislodge the West.
The blockade was a crucial turning point. It hardened western public opinion against the Soviet Union, accelerated the formation of NATO (April 1949), and made German division permanent.
West Germany (FRG) — founded May 1949
- Parliamentary democracy under the Basic Law
- Aligned with the USA and western Europe; joined NATO in 1955
- Received Marshall Plan aid; Deutschmark currency
- Capital at Bonn; Konrad Adenauer first chancellor
- Rapidly rebuilt into a market economy
East Germany (GDR) — founded October 1949
- Soviet-style one-party state under the Socialist Unity Party (SED)
- Aligned with the USSR; joined the Warsaw Pact in 1955
- Continued to pay reparations to the USSR; Soviet-style command economy
- Capital in East Berlin; heavily dependent on Soviet support
- Mass emigration to the West — 2.7 million left between 1949 and 1961
Berlin Wall (1961): sealing the divide: By 1961, East Germany was haemorrhaging its most educated and skilled workers through West Berlin. On 13 August 1961, the GDR began constructing the Berlin Wall, eventually a 155-km barrier of concrete, wire, and watchtowers. It stopped the emigration flow instantly and became the most powerful symbol of the Iron Curtain for the next twenty-eight years.

Despite the devastation of 1945, western Europe achieved a remarkable economic recovery over the following two decades. By the early 1960s, living standards in France and West Germany exceeded anything achieved before the war. This recovery was shaped by American money, strong political leadership, and a willingness to rebuild differently.
The Marshall Plan (1948–1952): America funds recovery: The European Recovery Programme injected $13 billion (around $150 billion in today's money) into western European economies between 1948 and 1952. The money paid for raw materials, machinery, food, and fuel.
The USA had strategic as well as humanitarian motives: - A prosperous western Europe would resist communist political parties (which were strong in France and Italy in 1945–47) - A rebuilt Europe would become a trading partner for American exports - Strong western states would be reliable allies in the Cold War
Recipient countries had to cooperate economically — this pushed western Europe towards trade liberalisation and set the foundation for what later became the European Union.
Konrad Adenauer and West Germany's reconstruction
Adenauer was West Germany's first chancellor (1949–1963) and the dominant figure of the early Federal Republic. He pursued three interlocking goals:
1. Westernisation: Adenauer firmly anchored West Germany in the western alliance. He championed German membership of NATO (1955) and the early European integration project (ECSC in 1951, EEC in 1957). He believed that embedding Germany in supranational institutions would reassure Germany's neighbours and prevent any return to nationalism.
2. Economic reconstruction: Adenauer worked closely with his Economics Minister, Ludwig Erhard, who implemented the social market economy — a system that combined free markets with strong social protections and an independent central bank (the Bundesbank). This model underpinned the Wirtschaftswunder.
3. Reconciliation: Adenauer negotiated the Luxembourg Agreement (1952), under which West Germany paid reparations to Israel and Jewish survivors of the Holocaust. He also cultivated a close relationship with France — symbolised by the Élysée Treaty of 1963 with de Gaulle — transforming centuries of Franco-German rivalry into the cornerstone of European integration.
The German 'Wirtschaftswunder' — the economic miracle
Between 1950 and 1963, West Germany's GDP grew at an average of 8% per year — one of the fastest peacetime growth rates in modern history. By 1960, West Germany was the third largest economy in the world.
Why did it happen?
- Marshall Plan aid jump-started industrial production
- The social market economy provided stability without strangling initiative
- West Germany had a large, skilled industrial workforce (many trained before the war)
- Currency reform (1948) eliminated wartime inflation at a stroke
- The Korean War (1950–53) created massive demand for German industrial goods
- Gastarbeiter brought additional labour as the domestic workforce could not keep pace with demand
The result was full employment, rising wages, and a consumer boom — cars, televisions, and refrigerators became commonplace in West German households for the first time.
Charles de Gaulle and France's recovery
France in 1945 faced not only physical devastation but political crisis — the Fourth Republic (1946–1958) was plagued by governmental instability, with 21 different governments in 12 years.
De Gaulle's return and the Fifth Republic (1958): Charles de Gaulle had led the Free French during the war and briefly governed France in 1944–46 before resigning in frustration. He was recalled in 1958 during the Algerian crisis and given powers to draft a new constitution. The Fifth Republic gave the president strong executive authority and stable government.
De Gaulle pursued an independent foreign policy — he wanted France to be a great power in its own right, not merely a US satellite. He withdrew France from NATO's integrated military command (1966), developed an independent nuclear deterrent (the 'force de frappe'), vetoed British membership of the EEC (1963 and 1967), and recognised China.
Economically, de Gaulle combined state intervention with market growth — a dirigiste tradition of French economic planning (the 'Plan') guided investment and modernisation, driving Les Trente Glorieuses.
Les Trente Glorieuses — France's thirty glorious years (1945–1975)
Les Trente Glorieuses describes the extraordinary three decades of prosperity that transformed France from a largely rural, traditional society into a modern industrial nation.
Key features:
- GDP grew at around 5% per year — faster than any previous period in French history
- The population rose sharply (a post-war 'baby boom' combined with immigration)
- Urbanisation accelerated: millions moved from farms to factory jobs in cities
- Consumer culture arrived — car ownership, household appliances, supermarkets
- The welfare state expanded: free healthcare, pension systems, and family allowances were built up
- State-led industrial planning (indicative planning via the Commissariat Général du Plan) guided investment into steel, energy, transport, and electronics
Les Trente Glorieuses ended with the oil shock of 1973–74, which revealed the vulnerability of France's energy-intensive growth model. But by then, France had been fundamentally transformed.
Linking recovery to the Cold War: Paper 3 essays often ask you to explain why western Europe recovered so quickly. Always connect the economic recovery to Cold War context:
- The Marshall Plan was a Cold War weapon as much as a humanitarian programme — the USA needed stable, prosperous western Europe to resist communism - Adenauer's westernisation strategy was only possible because the USA welcomed West German rearmament and integration into NATO as a Cold War asset - De Gaulle's independent foreign policy was itself a response to Cold War bipolarity — he wanted France to be a third pole, not a subordinate of Washington
So the Cold War simultaneously divided Germany and funded the recovery of the western half.
