The Cold War never escalated to the point of direct confrontation between the US and the USSR. In fact, aside from the nuclear arms race, the struggle for world dominance was primarily waged through propaganda campaigns, espionage, proxy wars, athletic rivalry at the Olympics, and the Space Race.
Proxy war
A war fought between two groups or smaller countries that represent the interests of other larger powers. These larger powers may support them but are not directly involved in the fighting.
The Cold War is generally considered by historians to have begun between 1947 and 1948, with the introduction of the Truman Doctrine and the Marshall Plan. US financial aid brought many Western countries under American influence in an attempt to contain communism. At the same time, the Soviets began to establish openly communist regimes in the countries of eastern Europe. These became satellites of the USSR. They were tactical bases for confrontation with the West, and a safeguard against a renewed threat from Germany.
The United States and the USSR gradually built up zones of influence around the world, dividing it into two vast opposing camps. It was not just a struggle between two enemies, it was a global conflict.
Political expert Raymond Aron called the Cold War:
Impossible peace, improbable war.
This is because the ideological differences between the two camps made peace impossible. War, on the other hand, was highly improbable because nuclear weapons acted as a deterrent.
The Cold War ended in 1991, after the collapse and dissolution of the Soviet Union.
Why was it called the ‘Cold’ War?
It was called the Cold War for a number of reasons:
First of all, neither the Soviet Union nor the United States officially declared war on the other. In fact, there was never any direct large-scale fighting between the two superpowers.
The war was only waged through indirect conflict. The US and USSR supported regional conflicts in their own interests, known as proxy wars.
It describes the ‘chilly’ relationship between the two Second World War allies.
Cold War history
A cold war is a war waged through indirect conflict, based on an ideological and geopolitical struggle for global influence between two or more superpowers. The expression ‘cold war’ was rarely used before 1945.
Don Juan Manuel - Fourteenth century
Some credit the fourteenth century Spaniard Don Juan Manuel with first using the term ‘cold war’ in Spanish, to describe the conflict between Christianity and Islam. However, he used the word ‘tepid’ not ‘cold’.
George Orwell - 1945
The English writer George Orwell first used the term in an article published in 1945 to refer to the hostility between the Western and Eastern blocs. He predicted that a nuclear stalemate would ensue between:
two or three monstrous super-states, each possessed of a weapon by which millions of people can be wiped out in a few seconds.
Furthermore, he warned of a world living in the constant shadow of the threat of nuclear war: ‘a peace that is no peace,’ which he called a permanent ‘cold war’. Orwell was directly referring to the ideological confrontation between the Soviet Union and the Western powers.
Nuclear stalemate
A situation where both sides possess equal amounts of nuclear weapons, meaning neither can use them. Doing so would result in mutual destruction.
Bernard Baruch - 1947
The term was first used in the United States by the American financier and presidential adviser Bernard Baruch. He delivered a speech during the unveiling of his portrait in the South Carolina House of Representatives in 1947, saying:
Let us not be deceived: we are today in the midst of a cold war.
He was describing the post–Second World War geopolitical relations between the United States and the Soviet Union.
For over 40 years the term ‘cold war’ became a staple in the language of American diplomacy. Thanks to newspaper reporter Walter Lippmann and his book ‘Cold War' (1947), the term is now commonly accepted.
Who were the principal participants of the Cold War?
We have already mentioned that the main rivalry during the Cold War was between the US and the USSR and their allies. Who were these allies that made up the Eastern and Western Blocs?
The Grand Alliance and the ‘Big Three’
In the Second World War, the three great allied powers, Great Britain, the United States, and the Soviet Union, formed a Grand Alliance in order to defeat Nazi Germany. This alliance was led by the so-called ‘Big Three’: Churchill, Roosevelt, and Stalin. These three leaders represented the three great powers, which were the principal contributors of manpower and resources, as well as strategy.
A series of conferences between the allied leaders and their military officials allowed them to gradually decide the direction of the war, the members of the alliance, and eventually, the postwar international order.
However, the alliance partners did not share political aims and did not always agree on how the War should be fought. Although the United Kingdom and the United States maintained close relations thanks to their bilateral Atlantic Charter, they were capitalist countries, while the USSR had been communist since the 1917 Russian Revolution. Nazi aggression against the USSR in 1941, in Operation Barbarossa, turned the Soviet regime into an ally of the Western democracies.
The Grand Alliance brought together two sides divided by their political and economic ideologies. In the post-war world, these increasingly divergent viewpoints created rifts between those who had once been allies and signalled the beginning of the Cold War.
By 1948, cooperation between the Western Allies and the Soviets had completely broken down. The world became deeply divided between the Western powers who promoted capitalism and the Soviet Union which embraced communism.
The Western world and capitalism
The Western Bloc was led by the United States of America. The US represented capitalism, with the strongest economy (by GDP) in the world during the cold war, and up to the present day. It was also known as the leader of the ‘Free World’, a propaganda term used to refer to the Western Bloc, since collectively it was the biggest democracy worldwide.
Capitalism is an economic system in which private actors can own and control the means of production. This means that people are free to set up private businesses and make money for themselves. The production and pricing of goods are dictated by market forces resulting from the interaction between private businesses and individuals, and not the government. Capitalism is founded on three principals: private property, profit motive, and market competition.
In a democracy, there are several competing political parties, each representing different sectors of society or political ideology. Governments are chosen through democratic elections; citizens vote for their preferred Party and thus participate in the democratic process. The freedoms and rights of individuals are extremely important, which is why freedom of speech and freedom of the press are guaranteed in a democracy.
During the Cold War, the Western Bloc consisted of the United States and its NATO allies. The North Atlantic Treaty Organization (NATO) was signed on the 4th of April 1949, and was supposed to provide a military counterweight to the Soviet bloc. It replaced the Brussels Treaty of 1948 between the UK, France, Belgium, the Netherlands and Luxembourg, which concluded in a collective-defense agreement also known as the Western European Union. NATO saw the US, Canada and Norway join the alliance.
The alliance’s purpose was to deter the Soviets from expanding their influence in Europe by allowing a strong North American presence on the continent and encouraging European political integration.
The Eastern bloc and communism
The Eastern bloc was led by the Soviet Union, officially the Union of Soviet Socialist Republics (USSR). The USSR was a socialist state that spanned Europe and Asia during its existence from 1922 to 1991. It was the second most powerful state, after the USA, during the Cold War and its goal was to spread communism worldwide.
Communism is an economic system in which all property is owned by the community, or state, meaning that private property is abolished. In a communist state, everybody must contribute according to their abilities, and only receive what they need. The Communist International (Comintern) was an international organization founded by the Soviet Union in 1919 that advocated world communism.
The political system of the Soviet Union was a federal single-party soviet republic. The USSR was divided into several federations and there was only one political party allowed: the Communist Party of the Soviet Union (CPSU). This meant that the Soviet Union was essentially a dictatorship. There were no democratic elections and the possibility of changing the government by election was nil. The state owned all the businesses and factories, as well as the land. The Communist Party was controlled by a single leader. The individual rights and freedoms of individual citizens were deemed less important than obedience to the state. Finally, the government controlled the media and censored anyone who disagreed with it.
The Eastern bloc consisted of the Soviet Union and its satellite states. The USSR thus had immense influence over the many countries that bordered it, especially in Eastern Europe.
Satellite state
A satellite state is a country that is officially independent but is in reality under the political or economic influence or control of another.
This influence was consolidated when the Warsaw Pact of 1955 was signed, establishing the Warsaw Treaty Organization, a mutual defence alliance that was originally composed of the Soviet Union, Albania, Bulgaria, Czechoslovakia, East Germany, Hungary, Poland, and Romania. The treaty meant that the USSR kept military troops on all the territories of the other participating states. A unified military command was also created, with the other countries having to volunteer their own troops to the Soviet Union.
The Non-Aligned Movement
In 1955, in the context of the wave of decolonisation that swept the globe, delegates from 29 countries met at the Bandung Conference, also referred to as the Asian-African Conference. They argued that developing countries should remain neutral and not ally with the US or the USSR, but rather come together in support of national self-determination to combat imperialism.
In 1961, drawing on the principles agreed in 1955, the Non-Aligned Movement (NAM) was founded in Belgrade and held its first conference, thanks to Yugoslav President Josip Tito. The aim was to give a voice to developing countries and encourage them to act on the world stage in international politics. For this reason, the member states of the Non-Aligned Movement could not be part of a multilateral military alliance. By the beginning of the twenty-first century, more than 100 states had joined the Non-Aligned Movement.
Below is a map representing how the world was divided for the majority of the Cold War:
World Map of the Cold War alliances in 1970
China and Mongolia, although communist states, did not depend on the USSR and had actually distanced themselves from the Soviet Union in the late 1950s and early 1960s during the Soviet-Sino split. The same can be said of Tito’s Yugoslavia.
Causes of the Cold War
There were many factors that made the Cold War between the United States and the Soviet Union inevitable. The most important are explained below.
Early tensions
First of all, the wartime alliance between the US and USSR was one of circumstances and not ideology. When Hitler broke the non-aggression pact he had signed with Stalin, by invading the Soviet Union, he took the Red Army by surprise, making important territorial gains. This forced the Soviet Union to join the Allied powers.
This meant there were many tensions between the allies, along with a range of complex issues:
The Allies were unsure of Stalin’s loyalty since he had allied himself with Hitler in 1939, through the Nazi-Soviet Pact.
The US did not open a second front in France until 1944, delaying the invasion of Europe, having previously opened a front in Italy during the summer of 1943. This delay allowed Hitler to concentrate his forces against the Soviets.
The USSR did not help the Polish resistance during the Warsaw Uprising of August 1944, in order to get rid of its anti-communist government.
The US and UK excluded the Soviets from secret talks with the Germans.
US President Harry Truman omitted to inform Stalin that he would deploy atomic bombs over the Japanese cities of Hiroshima and Nagasaki. Stalin’s suspicion and distrust of the West intensified as a result.
US victory in the Pacific, without Soviet help, alienated Stalin further and the USSR was denied any share of the occupation in that area.
Stalin believed the US and Britain were allowing Germany and the Soviet Union to fight it out, so that both countries could be weakened.
At the end of the Second World War, the uneasy wartime alliance had begun to unravel.
Ideological differences
An ideological schism had separated the Allied powers since World War One and was evident at the peace conferences of Yalta and Potsdam in 1945. This is when the allies decided what would happen to Europe, and in particular Germany, at the end of the Second World War. There were two reasons for this:
The emergence of communism
The Bolshevik Revolution of October 1917 replaced Russia's tsar with a "dictatorship of the proletariat", and established a communist state. The Bolsheviks then decided to withdraw Russia from World War One as civil war engulfed the country, leaving Britain and France to fight the Axis powers alone. The White Army, tsarist supporters who fought the Bolsheviks during the Russian Civil War, were then supported by the Western powers.
Capitalism and communism: ideological opposites
The political and economic systems of the capitalist USA and communist USSR were ideologically incompatible. Both sides wanted to affirm their model and force countries around the world to conform to their ideologies.
Disagreements over Germany
At the Potsdam Conference in July 1945, the US, USSR, and Britain agreed to divide Germany into four zones. Each zone was administered by one of the Allied powers, including France.
Furthermore, the USSR would receive reparation payments from Germany to compensate for the country's losses.
The Western powers envisioned a booming capitalist Germany that contributed to world trade. Stalin, on the other hand, wanted to destroy the German economy and ensure that Germany could never become powerful again, after Russia nearly lost to them during the Second World War.
Fierce competition between East and West Germany ensued. The French, US, and British sectors remained free to trade and reconstruction was started, whilst Stalin forbade the Russian zone from trading with other zones. Much of what was produced in the Russian zone was also confiscated, including infrastructure and raw materials, which were brought back to the Soviet Union.
In 1947, Bizonia was created: the British and American zones unified economically thanks to a new currency, the Deutschmark; this was introduced to the Western zones to stimulate the economy. Stalin feared that this new idea would spread to the Soviet zone and strengthen rather than weaken Germany. He decided to introduce his own currency in East Germany, called the Ostmark.
Nuclear arms race
In 1949, the USSR tested its first atomic bomb. In 1953, the US and USSR both tested hydrogen bombs. The Americans believed that the Soviets had caught up technologically, which led to a nuclear arms race. The two superpowers tried amassed nuclear weapons, both sides fearing they might fall behind in research and production. Over 55,000 nuclear warheads were produced during the Cold War, with the US spending an estimated $5.8 trillion on nuclear weapons, laboratories, reactors, bombers, submarines, missiles, and silos.
Nuclear warfare eventually became a deterrent rather than a weapon. The theory of mutually assured destruction (MAD) meant that a superpower would never use its nuclear weapons knowing that the other side would automatically do the same. This relied on neither side being able to do a “first strike”.
What was the scale of the Cold War?
Although the Cold War began as a conflict between two superpowers it quickly escalated into a global matter.
Conflict over Germany and Europe
As explained above, Western powers and Stalin’s Soviet Union disagreed about how Germany should be administered after the War. With tensions rising, the Soviets decided to act upon Germany, and more importantly Berlin, to “squeeze” the allies out. The landscape of Eastern Europe was also altered by the Soviets.
Berlin blockade
After the Second World War, Berlin was divided into four zones. Berlin was deep inside East Germany, in the Soviet zone. West Berlin’s status had always worried Stalin because it constituted an enclave inside the Eastern bloc and behind the Iron Curtain. This caused Stalin to block all road and rail access to the western part of Berlin from June 24, 1948: this was known as the Berlin blockade. By cutting communication between West Berlin and West Germany Stalin hoped to put pressure on the allies and force them to leave West Berlin altogether. However, the Americans reacted by organising an extraordinary air bridge, restocking the city entirely by air. They succeeded in transporting over 1.5 million tons of food, fuel, and other supplies to West Berlin, and made Stalin’s blockade completely ineffective. On May 12th, 1949, after 322 days, he abandoned the blockade, and once again free access to the city by land was restored.
The Berlin wall
Each of the superpowers instrumentalized their respective zones in Berlin to showcase their regimes and strengthen their image. The US was successful, and between 1949 and 1961, three million Germans emigrated to the FRG. For the USSR, Berlin had become a complete failure. As a result, the GDR erected a wall between the zones to stop free movement between east and west. It was erected on the night of August 13th, 1961 and became known as the “Berlin Wall”. East Germans could no longer enter West Berlin, which was one possible route out of the Soviet Union.
Eastern Europe and the rise of populist dictatorships
Between 1945 and 1953, Stalin set up puppet states, communist governments he had installed with leaders he could control. Resistance was severely punished. The USSR expanded its influence across states such as Poland, Czechoslovakia, and Hungary. The USA, fearing that the Soviet domination of Eastern Europe would be permanent, began a counter-offensive to influence nations which it deemed vulnerable to communism. This became known as the policy of containment.
Widening of the Cold War
By the 1950s, competition between capitalism and communism had spread to the Middle East, Asia, and Latin America, each superpower vying for control.
Then, in the 1960s, the Cold War reached Africa. Many former colonies which had gained independence from European empires, sided with either the Americans or Soviets to receive economic aid.
The global war
Finally, the Cold War became a global war. Some of the most important Cold War conflicts took place in Asia. This is because communists took power in China in 1949, which meant that Americans, on the basis of the Truman Doctrine, stationed troops in Asia, most notably in countries bordering China.
Cold War Summary
Let's take a quick look into the timeline of the most important facts and events during the Cold War.
Red Scare
The Red Scare was a period of anti-Communist fervour and mass hysteria over the perceived threat posed by communists in the US during the Cold War. Some believed that a communist coup was imminent, especially since the American Socialist Party and Communist Party were well established at the time.
The Red scare intensified in the late 1940s and early 1950s. During this period, federal employees were evaluated to determine their loyalty to the government. The House Un-American Activities Committee (HUAC), formed in 1938, and most notably Senator Joseph R. McCarthy, investigated allegations of “subversive elements” in the federal government, and exposed communists working in the film industry. This is where the term McCarthyism comes from: the practice of making accusations of subversion and treason, especially when related to communism and socialism.
Communists were often referred to as ‘Reds’ for their allegiance to the red Soviet flag. This climate of fear and repression finally began to ease by the late 1950s.
Wars around the world
There was never any direct large-scale fighting between the US and USSR. The two superpowers waged war only by supporting different regional conflicts, known as proxy wars.
Korean War
In 1950, Korea was divided into two zones: the communist north, and the capitalist democratic south. In a bid to contain the spread of communism to South Korea, the US sent troops to the country. The Chinese responded by sending their own troops to the border. Following clashes along the border, the Korean War began on the 25th of June 1950. North Korea invaded South Korea when over 75,000 soldiers from the North Korean People's Army poured over the 38th parallel. The war killed nearly 5 million people, ending in a stalemate. Korea is still divided to this day and, theoretically, still at war.
Vietnam War
Just like Korea, Vietnam was divided into a communist north and pro-West south. The Vietnam War was an extremely long and costly conflict that pitted North Vietnam against South Vietnam and the United States in the 1960s. The Soviet Union sent money and supplied weapons to the communist forces. By 1975, the US was forced to withdraw, and the North seized control of the South. More than 3 million people and over 58,000 Americans died in the conflict.
Afghanistan War
In the 1980s, just as the United States had done in Vietnam, the Soviet Union intervened in Afghanistan. In response, the US supported the Mujahideen (Afghani guerrillas) against the USSR, by sending them money and weapons. The USSR was unsuccessful in its efforts to turn the country into a communist state during the Afghan War, and the Taliban, a US-funded Islamic extremist group, eventually claimed power in the region.
Space Race
Space exploration served as another arena for supremacy in the Cold War. The United States and the Soviet Union competed for superior spaceflight capabilities. The space race was a series of technological advancements that were exhibits of superiority in spaceflight, each nation trying to outdo the other. The origins of the space race lie in the nuclear arms race between the two nations after the Second World War when ballistic missiles were being developed.
On 4 October 1957, the Soviets launched Sputnik, the world's first satellite, into orbit. On 20 July 1969, the US successfully landed on the moon, thanks to the Apollo 11 space mission. Neil Armstrong became the first man to walk on the moon.
Cuban missile crisis
Both the Soviet Union and the United States developed intercontinental ballistic missiles in 1958 and 1959 respectively. Then, in 1962, the Soviet Union began to secretly install missiles in communist Cuba, in easy striking distance of the US.
The confrontation that followed became known as the Cuban missile crisis. The US and USSR were on the brink of nuclear war. Thankfully an agreement was reached, and the USSR withdrew its planned missile installation. The agreement showed that the two countries were extremely wary of using nuclear missiles against each other, both fearing mutual annihilation.
‘Détente’
Détente was a period of easing in Cold War tensions from 1967 to 1979. This phase took a decisive form when US President Richard Nixon visited the secretary-general of the Soviet Communist party, Leonid Brezhnev, in Moscow, in 1972.
During this era, cooperation with the Soviet Union increased. The historic Strategic Arms Limitation Talks (SALT) treaties were signed in 1972 and 1979.
How did the Cold War end?
The Cold War gradually came to an end. Unity in the Eastern bloc started to falter during the 1960s and 1970s when the alliance between China and the Soviet Union fell apart.
In the meantime, some Western countries as well as Japan became more economically independent of the US. This led to more complex relationships internationally, which meant that smaller nations were more resistant to efforts to vie for their support.
Gorbachev: perestroika and glasnost
The Cold War began to break down properly in the late 1980s, during Mikhail Gorbachev’s administration. His reforms, like the creation of the Congress of People’s Deputies, weakened the Communist Party by transforming the Soviet political system into a more democratic one, removing a raft of totalitarian aspects.
These reforms were meant to distract from the economic problems in the Eastern Bloc where goods were in short supply. The USSR was not able to keep up with American military spending. To stop citizens from revolting, economic reforms known as perestroika, or ‘restructuring’, were passed and the restrictions on freedom of expression were relaxed in a policy called glasnost, or ‘openness.’
But this was too little too late. Communist regimes in Eastern Europe were collapsing as democratic governments rose to replace them in East Germany, Poland, Hungary, and Czechoslovakia.
The Fall of the Berlin Wall
In 1989, the Berlin Wall, the symbol of the Iron Curtain, was torn down by Germans on both sides as they sought to unify Germany. At the same time, waves of anti-communist feeling spread throughout the Eastern Bloc.
The collapse of the Soviet Union
The end of the Cold War was finally marked by the dissolution of the Soviet Union into fifteen newly independent nations in 1991. The USSR became the Russian Federation and no longer had a communist leader.
Cold War - Key takeaways
- The Cold War was an ongoing geopolitical rivalry between two countries and their respective allies. On one side was the United States and the Western Bloc. On the other side were the Soviet Union and the Eastern Bloc. This began in the aftermath of the Second World War.
- During the Cold War, there were three main sides: the Western Bloc, the Eastern Bloc, and the Non-Aligned Movement.
- The Western Bloc was led by the United States of America and represented capitalism and democracy.
- The Eastern Bloc was led by the Soviet Union and represented communism and totalitarianism.
- The Non-Aligned Movement represented all the countries (mainly newly created states) that did not want to be part of the Cold War and ally with either the US or the USSR.
- A range of factors led to the Cold War: the uneasy wartime alliance between the US and USSR was riddled with tension; ideological differences; conflicts over how the world should be governed; and the race to create the most powerful nuclear weapons.
- The Cold War was confined to Europe and Germany at first but soon expanded into South America and Asia. In doing so, it became a global war that involved the whole world.
- The Cold War ended when the Soviet Union was dissolved in 1991 and many Eastern European countries gained independence from Soviet influence and embraced democracy instead.
- The fall of the Berlin Wall in 1989 was symbolic of the end of the Cold War across the world.

Frequently Asked Questions about Cold War
What was the Cold War?
The Cold War was an ongoing geopolitical rivalry between two countries and their respective allies. On one side was the United States and the Western Bloc. On the other side was the Soviet Union and the Eastern Bloc. This began in the aftermath of the Second World War.
When was the Cold War?
The Cold War is generally considered to have begun between 1947 and 1948 when the United States and its allies openly criticized Stalin and the Soviet Union, most notably by introducing the Truman doctrine, a plan to contain communism and stop its spread. The Cold War ended in 1991 when the USSR was dissolved.
Who won the Cold War?
It is generally accepted that the United States won the Cold War, since the Soviet Union was dissolved in 1991, and communism across Eastern Europe disappeared. Capitalism and democracy, by contrast, became the main political models across the world. However, some historians believe that it was not so much the case that the Americans ‘won’, but rather that the Russians lost. The dissolution of the Soviet Union was caused by a lack of financial control (the Soviets spent most of their money on proxy wars and developing nuclear weapons) and the communist model created a stagnant economy, leading to dissent within the Soviet states.
Why was it called the Cold War?
It was called the ‘Cold War’ because the USSR and US never declared war on each other and never engaged in direct conflict. The war was only waged through indirect conflicts known as proxy wars. The term ‘cold’ also described the chilly relations between the two superpowers.
What caused the Cold War?
The Cold War was caused by the ideological schism between the two superpowers: the United States embraced capitalism whilst the Soviet Union opted for communism. As a result, they disagreed about what to do with post-War Germany. They started to distance themselves and soon launched a full-scale indirect conflict to propagate their political models around the world.
