Summary

After the defeat of Nazi Germany in 1945, the Allies decided to split Germany into four zones occupied by the USA, Britain, France and the Soviet Union.

However, as tensions between the West and East increased following the end of the Second World War in August 1945, it was clear that the Allies had differing views on how to best govern Germany.

Economic differences between the Capitalist West and the Communist East prompted the countries of the USA, Britain and France to join their zones together to create Trizonia. Stalin and the Soviet Union saw this as the West’s attempt to weaken the Soviet zone in Germany. This was made worse by the creation of a new currency called the Deutschmark, which all but split Germany in two.

As a result, the Soviet Union shut off the land routes in Soviet-controlled Germany,  preventing Trizonia from accessing its zone in Berlin. This became known as the Berlin Crisis.

The Berlin Airlift meant that war was avoided, and West Berlin remained under the control of the capitalist West. However, it remained a source of tension and millions of East Germans used Berlin to flee Communism and live in the West. To bring this mass migration to an end, the GDR government constructed a wall to divide East and West Berlin. The Berlin Wall became a symbol of the 'Iron Curtain' between East and West for almost 30 years.

The Division of Germany

  • At the Potsdam Conference, it was agreed that Germany and Berlin would be split into four zones of occupation:

    • Each zone was to be controlled by the USA, Britain, France and the Soviet Union

  • The division was only meant to be temporary, while a new German government was created

  • A joint organisation called the Allied Control Commission (ACC) was in charge of running Germany

  • However, tensions between the West and East led to disagreements between the four zones on how to best treat Germany

  • In March 1948, the representative for the Soviet Union’s zone stormed out of a meeting held by the ACC

  • The original four zones of occupation, agreed in 1945, did not last long

  • In 1947, the USA and Britain merged their zones to create ‘Bizonia’

  • After the walkout of the Soviet representative in March 1948, France merged their zone with the USA and Britain to create ‘Trizonia’

  • In March 1948, Germany was split into two main zones:

    • The Western countries of the USA, Britain and France controlled the Western Zone

    • The Soviet Union controlled the Eastern Zone

The Berlin Blockade

  • As with Germany, Berlin was split into two parts in March 1948:

    • The USA, Britain and France occupied the western zone, known as Trizonia

    • The Soviet Union occupied the eastern zone

  • Trizonia introduced the Deutschmark in June 1948, 

    • This new currency was just for the Western Zone had essentially formally divided Germany into two

    • Stalin wanted to demonstrate that Germany should not be divided

  • West Berlin was an isolated capitalist ‘island’ in the middle of Soviet controlled East Germany

    • Stalin decided that blockading - or preventing Western access to Berlin - would be an effective way of displaying his anger and lead to him gaining control over all of Germany’s capital 

Diagram showing causes of the Berlin Blockade. Three reasons are listed: 1) West Berlin relied on food from East Germany, 2) Allies had to travel through Soviet territory to reach West Berlin, and 3) The Soviet Union had 1.5 million soldiers in Germany. Each reason is followed by an explanation of how it gave the Soviet Union control over access to West Berlin. These led to the Soviet decision to block all land routes into West Berlin.

How did the Soviet Union Blockade Berlin?

  • As Berlin was deep inside the Soviet-occupied zone, Stalin believed it would be easy to cut off western access to the city

    • Members of Trizonia had to use the two agreed land routes and two air routes to access their western zone in Berlin

  • In June 1948, the Soviet Union closed road, rail and canal links across Soviet-controlled Germany 

  • Without access to West Berlin, the USA, Britain and France would not be able to send supplies:

    • West Berlin only had enough food for 36 days

    • West Berlin lacked important resources like fuel and medicine

  • Stalin hoped that the Western powers would give up their control of West Berlin, which would allow the Soviet Union to control the whole capital

    • It would also allow him to spread propaganda about the triumph of Communism over Capitalism

The Berlin Airlift

  • The blockade put the US and Britain in a very difficult position

  • They risked war if they attempted to ignore the closed land routes and move supplies over land

  • Doing nothing would most likely lead to the Western-occupied Zone in Berlin being handed over to the Soviet Union

  • The West decided to fly supplies into Berlin, knowing that the Soviet Union itself would be risking war if it shot any planes down

    • From June 1948 to May 1949, the West flew supplies into West Berlin in what was known as Operation Vittles (the codename) or the Berlin Airlift

What happened during the Berlin Airlift?

A mind map diagram titled "The Berlin Airlift" is at the center, with four categories branching out: "Supplies," "Airports," "Casualties," and "Soviet Reaction."

Under "Supplies," it states that in January 1949, 170,000 tons of supplies were sent into Berlin, and that the USA and Britain flew in around 1,000 tons of supplies every day.

Under "Airports," it notes that at Berlin–Tempelhof, an airplane landed every 45 seconds during the height of the Berlin Airlift, and that Berlin–Tegel was a new airport built by the French military.

Under "Casualties," it explains that although at least 78 people were killed in aircraft accidents, the Soviet military caused no casualties.

Under "Soviet Reaction," it says that an offer to move to East Berlin to receive food was refused by most West Berliners, and that the Allies refused Stalin’s offer to lift the Berlin Blockade if the Deutschmark was removed from West Berlin.

The impact of the Berlin Crisis

  • Stalin could not stop the Berlin Airlift because shooting down aeroplanes carrying supplies would lead to war

  • The longer the airlift went on, the more humiliating it became for the Soviet Union

  • On 9 May 1949, the Soviet Union lifted the Berlin Blockade

    • The Western Allies continued to fly in supplies until 30 September 1949, so that West Berlin would be supplied in the event of a future blockade

  • The Berlin Airlift was a massive victory for the West over the East, but this created even greater tension between the two superpowers

  • Several key events happened partly as a result of the Berlin Crisis

The Creation of West and East Germany 

  • After the Soviet Union lifted the Berlin Blockade, it was clear that Germany would continue to be divided

  • The members of Trizonia acted first and officially created the Federal Republic of Germany (FRG) in West Germany

A timeline showing the events that established the FRG
  • The city of Bonn was chosen as the capital

  • West Berlin continued to be controlled by and owned by the FRG, despite being deep inside Soviet controlled East Germany

The process of creating the GDR

  • The response of Stalin to the creation of the FRG was to formally create a new state in East Germany known as the German Democratic Republic (GDR)

Timeline of the GDR's creation: Soviet Union establishes GDR on 7 Oct 1949, Volkskammer (parliament) created, Wilhelm Pieck elected president on 11 Oct 1949.
A timeline showing the events that established the GDR
  • East Berlin remained the capital of the GDR

  • East Germany and West Germany did not recognise each other as official states until 1972

  • Cold War tensions increased following the creation of both the FRG and the GDR

The Berlin Wall

  • Throughout the 1950s, relations between the superpowers continued to be hostile, and Berlin remained a source of tension between them

  • Stalin had died, and there were hopes that relations would improve under the new Soviet Leader, Nikita Krushchev

    • However, the shooting down of a US spy plane over the Soviet Union in 1960 confirmed the USSR’s fears about American espionage and increased tensions

    • Khruschev believed American spies were operating in Berlin and gaining easy access to Soviet secrets

  • Another issue was the mass migration of East German citizens to the West through Berlin

    • The freedom and opportunities available in capitalist countries appealed to many East Germans

    • This caused a skills gap or ‘brain drain’ in East Germany

  • Over 40,000 East Germans escaped the GDR through Berlin in one day in August 

    • Walter Ulbricht, the leader of the GDR, urged Khrushchev to act quickly to prevent more East Germans from leaving

    • Under nightfall, the East German government placed barbed wire between East and West Berlin on 12 August 1961 and placed guards near the divide

    • The Berlin Wall developed from simple barbed wire to a complex concrete structure during the 1960s

The consequences of the Berlin Wall

  • As there had been free movement between East and West Berlin, many people travelled between the two sectors to visit family and friends or for work

    • As a result, many people became stuck in East Berlin

  • The wall separated German families and friends for years

  • Many East Germans continued to attempt escape plans to West Berlin

  • The GDR killed over 130 people attempting to go over, around or under the Berlin Wall between 1961 and 1989

  • Escape plans included:

    • climbing and jumping from windows next to the wall

    • flying over the wall in hot air balloons

    • using open-top cars to duck underneath the barriers at the Berlin Wall's checkpoints

    • using the sewer systems to travel to West Berlin

  • In 1962, the failed escape attempt by Peter Fechter caused international outrage

    • The GDR border guards shot Fechter when he attempted to escape

    • Fechter fell into no-man's-land between the Wall

      • The FRG border guards could not go and rescue Fechter

      • The GDR border guards did not attempt to treat Fechter's injuries

    • Fechter died of his injuries 45 minutes after he was shot

      • The nature of Fechter's death damaged the GDR's reputation

The impact of the Berlin Wall on Cold War tensions

  • Initially, the Berlin Wall increased tensions between the USA and the Soviet Union

  • Some positive consequences occurred from the 1960s to the 1980s as a result of the Berlin Wall

Reasons why the Berlin Wall eased tensions

  • The Berlin Wall meant there was less chance of a nuclear war developing over Berlin

    • Kennedy stated: "A wall is a hell of a lot better than a war”

  • The Berlin Wall ended the day-to-day comparison between communist East Berlin and capitalist West Berlin

    • This allowed both states to develop and function independently from each other

Reasons why the Berlin Wall escalated tensions

  • It was a diplomatic failure for the USA and the Soviet Union

    • It showed that the attempts to talk about the issue of Berlin had failed

  • The Berlin Wall created a physical divide to match the ideological divide between East and West

    • It became a symbol of the Cold War until 1989

Examiner Tips and Tricks

A common misconception that students have is that the East German government constructed a concrete wall overnight. The Berlin Wall was under constant development from its creation. The GDR replaced the temporary divide of barbed wire and cinder blocks. In 1965, the divide became a series of 5-metre-high concrete walls.
