Origin of the cold war:
Mistrust between the west and the USSR
Suspicions and tensions increase
During WW2, the USA, USSR and Britain formed a grand alliance to
defeat Germany – uneasy alliance
Yalta Conference (in USSR)
Feb 1945
Big three: Roosevelt, Churchill, Stalin
Main purpose: to decide what to do about Germany and those
controlled by Germany, once the nazis had been defeated
Agreement: Germany would be divided into 4 zones
Zones of occupation: would be administered by one of the big three
allied powers
Agreed that the countries in eastern Europe should be allowed to
hold elections
Potsdam Conference (in Germany)
July – August 1945
Present: Churchill, Truman, Stalin
At this point: Soviet army was in control of eastern Europe,
communist government in Poland
Roosevelt had died and been replaced by Truman (much more anti-
communist and suspicious of Stalin)
USA developed and tested the first atomic bomb without informing
Stalin, creating more mistrust
Key area of disagreement: what to do about Germany
Occupation of Germany
USSR – eastern zone
USA, Britain and France – western zones
City of berlin divided into 4 sectors
Agreed that Germany remain united and that economically they
should work in co-operation with the long-term goal of keeping
Germany one country
Creation of the spheres of influence:
USSR ensured that soviet friendly governments came into power
across the east
These countries became known as soviet satellite states
The free elections, which the USSR had agreed to at Yalta, did not
take place
