The Soviet Union's desire to spread communism and establish satellite states in Eastern Europe also heightened tensions with the United States.
The Grand Alliance was formed during World War II, consisting of the USA, the USSR, and Britain, united in the goal of removing the Nazis
The first conference was held in Tehran in December 1943, where the USA wanted Stalin's support to defeat the Japanese, the USSR wanted a second front in Western Europe, and Britain wanted support in defeating Nazism and defending its empire
The USA and Britain agreed to invade Western Europe in May 1944 to ease pressure on the USSR, who were being invaded by the Nazis
In February 1945, the Grand Alliance met in Yalta to discuss the post-war future, deciding to split Germany into four zones controlled by the USA, USSR, Britain, and France
Berlin was also split into four zones, and the Nazis were to be prosecuted with the establishment of the United Nations to prevent future wars
Stalin wanted Poland as a buffer zone to prevent future invasion, leading to disputes over free elections in Poland
The Potsdam Conference in August 1945 confirmed agreements from Yalta, establishing the United Nations with five permanent members and denazification of Germany
Germany was reduced in size, split into four zones, and the Soviet Union received 25% of the output of the other three zones as compensation
Stalin pushed for harsh reparations from Germany, but Truman opposed this, allowing Germany to pay in equipment, materials, and money
Stalin wanted to share the occupation of Japan after their surrender, but Truman refused, leading to tensions and the beginning of the Cold War
The ideologies of the East and West were opposed, leading to the collapse of the Grand Alliance after the defeat of the Nazis
Marshall Plan aimed to give people a stake in their own society to prevent communism
Aid recipients had to commit to trading with the USA and a review of their country's finances
Marshall Plan successful in supporting Greece against Communists and confirming USA's commitment to containing communism
Deepened rivalry between USA and USSR, confirmed split between communist and non-communist Europe
Truman Doctrine and Marshall Plan:
In February 1947, Britain informed the USA that they could no longer afford to keep troops in Greece and Turkey
Truman believed that if Britain withdrew, these countries were likely to become communist
Truman Doctrine: USA's involvement in Europe to prevent Stalin from spreading communism
Truman's speech on 12th March 1947 outlined concerns for Europe after World War II
Truman worried about the conditions in Europe making communism more attractive
Truman believed in the domino effect, where one nation falling to communism would lead to others following
Truman stated that countries faced a choice between capitalism and communism, with communism being evil because people were not free
Containment policy: USA's aim to stop the spread of communism
Marshall Plan: announced in April 1948 by General George C. Marshall, providing 17 billion dollars in aid to help rebuild Europe
Aid given to 16 countries, with the largest beneficiaries being Britain and France
Common Form strengthened trade links between communist countries and aimed to prevent them from joining the Marshall Plan
Soviet-led countries did not have enough money to support each other financially
Increased tension between Western Europe (tied to the US by the Marshall Plan) and Eastern Europe (under Soviet control) set the stage for the Cold War
Comic-Con and Common Form:
Stalin saw Marshall Plan as a direct attack on the USSR, accusing Truman of using it for selfish reasons
Stalin set up Comic-Con (Council for Mutual Economic Assistance) and Common Form (Communist Information Bureau) as a positive alternative to the Marshall Plan
Common Form aimed to remove opposition to Soviet control in communist-led countries
Tensions between Tito of Yugoslavia and Stalin led to Yugoslavia being expelled from Common Form in 1948
Stalin wanted to prevent future invasion into Eastern Europe, mainly from Germany and other European nations
Stalin aimed to create a buffer zone in Eastern Europe to prevent future invasions
At Yalta, Stalin promised free and fair elections in Eastern European nations occupied by the USSR
USSR used salami tactics to take over Eastern European countries, dealing with each country one slice at a time by fixing elections and removing opponents
The USA, particularly Truman, saw USSR's actions as a betrayal of the agreements made at Yalta
USSR's Red Army occupied nine countries and sought to influence two more to create a buffer zone
Six countries influenced by the USSR using the acronym PREACH:
P is for Poland:
USSR occupied Poland after waiting for the Warsaw Uprising to be put down
London Poles, exiled Polish politicians, were initially part of the government but were later forced to flee or face imprisonment
Communist party formed the government after the second election in 1947
R is for Romania:
Red Army took control of Romania in 1944 and influenced elections in 1945
Communists gained full control after the 1947 election
E is for East Germany:
Became a communist state in 1949 and was considered essential to the USSR's buffer zone
A is for Albania:
Reliant on Soviet aid and had a communist government from 1944
C is for Czechoslovakia:
Democracy until the Nazis invaded in 1938
Communist government established in 1948 with Stalin's support
H is for Hungary:
1945 elections returned a coalition government, but a communist government was established by 1949 after intimidation and another election
Establishment of satellite states confirmed the division between East and West, acting as a buffer for the Soviet Union against attacks from the West
Truman saw the expansion of communism into satellite states as evidence of the Soviet Union's plan to spread communism worldwide, increasing tensions between the superpowers
Winston Churchill referred to an "iron curtain" descending across Europe, symbolizing a military and ideological barrier drawn by the Soviet Union
Churchill emphasized the importance of cooperation between the UK, USA, and Western European countries for peace in the future
At the Yalta Conference in 1945, it was decided to divide Germany into four zones occupied by the USA, the USSR, France, and Great Britain
The division of Germany was intended to be temporary, but by the 1950s, it became clear that it would be long-lasting
The Western allies wanted to rebuild Germany's economy for trading partnerships, while the USSR wanted to use raw materials to help rebuild Russia
From 1945 to 1947, tensions increased between the Allies and the USSR over the future of Germany
In March 1948, the USA and Britain combined their zones to create byzonia, which further angered Stalin
The French joined byzonia to create trizonia, splitting Germany and Berlin into two sections
Trizonia introduced a new currency called the Deutsche Mark, angering Stalin and creating two Germanies
Stalin blocked land access to Berlin in June 1948, starting the Berlin blockade to prove that the division of Germany could not work
The Berlin airlift, known as Operation Vittles, began on June 24, 1948, delivering supplies to Berlin by air to counter the blockade
The airlift continued until May 9, 1949, when Stalin lifted the blockade as the West had responded peacefully and won the propaganda war
The blockade led to the formation of East and West Germany, with the Federal Republic of Germany established in the West and the German Democratic Republic in the East
