How did the Communist Satellite States Worsen Cold War Tensions? - Timeline & Summary

Timeline from 1940 to 1948 showing Lithuania, Estonia, Latvia (1940); East Germany, Romania (1945); Bulgaria (1946); Poland (1947); Czechoslovakia, Hungary (1948).

Tensions between the USA and the Soviet Union were made worse following the demonstration of the atomic bombs on Japan and the Long Telegram and Novikov Telegram in 1946.

Stalin was concerned for the security of the Soviet Union. He wanted to establish a ‘buffer zonebetween the Soviet Union and the West. To do this, communist governments in Poland, Hungary and Romania would need to be created.

However, free elections in Eastern Europe had been one of the agreements at the Yalta conference. Attempts to spread communism in Eastern Europe would be seen as aggressive by Britain and the USA.

Nevertheless, by 1948, the Soviet Union had incorporated a number of ‘satellite states’ under its control. Intimidation and violence were used in several countries to ensure elections were swayed towards the communists. 

As a result, Truman created both the Truman Doctrine and the Marshall Plan to protect other countries from falling into communist hands.

Why did Stalin Want Control of Eastern Europe?

  • The Soviet Red Army had liberated many countries in Eastern Europe from Nazi control at the end of the Second World War

  • Stalin wanted to keep control of these countries to act as a ‘buffer zone’ between the East and West

  • These countries were called satellite states because of how they seemed to orbit the Soviet Union

  • Truman’s concern about the spread of communism was confirmed as each country fell under Soviet control

  • Churchill’s ‘Iron Curtain’ speech was in response to the creation of satellite states such as Hungary, Poland, Romania and Bulgaria

The ‘Baltic States’, 1940

  • The ‘Baltic States’ were taken over by the Soviet Union during the Second World War

  • While the Soviet Union saw them as legitimate Soviet states, they saw their incorporation into the Soviet Union as illegal

Poland and The Warsaw Uprising, 1944-45

  • In 1944, the Soviet Red Army waited until the Warsaw Uprising had been crushed before occupying Poland

  • At the Yalta conference, the Grand Alliance had agreed to allow free elections to be held in Poland

  • However, Stalin was concerned that free elections would lead to a non-communist government being elected

  • A coalition government was created in June 1945 featuring mainly communist supporters and a few members of the London Poles

  • During the 1947 elections, a campaign of violence and intimidation led to the creation of a fully communist government

Romania, Bulgaria and East Germany, 1944-45

  • It was agreed by the Allies at the Yalta Conference that East Germany would be under the Soviet Union's influence

  • Romania and Bulgaria both lost their monarchies, which were replaced by communist governments

Hungary 1945-49

  • Non-communists won the 1945 election in Hungary

  • However, a communist politician called Rakosi took control of the secret police and imprisoned political opponents

  • After the Prime Minister of Hungary resigned, the Communists won the 1947 election

  • All other political parties were banned in 1949

Czechoslovakia 1948

  • Czechoslovakia had been a democracy from 1919 to 1938 until it was occupied by Nazi Germany

  • After the war, a coalition government was led by a non-communist called Edward Benes

  • Stalin saw this as a threat to his ‘buffer zone’ and wanted a communist government in power

  • In 1948, a coup led by the pro-communist Klement Gottwald took over the government with support from the Soviet Union

Communism in Yugoslavia and Albania

  • Yugoslavia and Albania were considered satellite states, even though they were never occupied by the Soviet Red Army

  • They were given more independence than countries neighbouring the Soviet Union

The USA’s Reaction to the Satellite States

  • At both the Yalta and Potsdam conferences, Roosevelt and Churchill had accepted that the Soviet Union would influence Eastern Europe

  • However, they also saw free elections as an important part of post-war Europe

  • Truman saw the creation of satellite states as a deliberate attempt to spread communism

  • Churchill’s ‘Iron Curtainspeech in 1946 worsened relations between East and West, especially between the USA and the Soviet Union

  • The satellite states challenged Truman’s policy of containment, prompting him to establish the Truman Doctrine and Marshall Plan

Worked Example

Explain the importance of the creation of the satellite states in Eastern Europe on US-Soviet relations

8 marks

Partial answer:

 The creation of the satellite states in Eastern Europe worsened US-Soviet relations. From 1945 to 1948, Stalin instructed the Red Army to invade various Eastern European countries such as Poland. He ensured a communist government was formed by rigging elections and using violence. This worsened US-Soviet relations as, at the Yalta conference, Stalin had promised the USA that they would allow free elections in Eastern Europe. Stalin's actions violated this promise. This worsened US-Soviet relations as the USA became more hostile to the Soviet Union. It created a lack of trust and fear in the Soviet Union's actions, leading to the USA trying to 'contain' the spread of communism.

Examiner Tips and Tricks

This style of question in the exam paper would be worth 8 marks. An examiner would expect you to write two paragraphs analysing the importance of an event on a wider theme like US-Soviet relations. A good response to this style of question would have:

  • logical structure of paragraphs. Within each paragraph, each sentence should link to the next. This will build a strong argument as to why the event is important to the wider theme

  • Specific own knowledge linked to the event, showing in-depth knowledge of the period

  • A clear explanation as to why the event was important to a wider theme. In the example above, you can see the phrase 'this worsened US-Soviet relations' is used frequently. This helps to keep the response focused on the question
