6, key topic 3 - The Cold War in the 1950s

Korea Hardens the Cold War

The Korean War began on 25 June 1950, when communist North Korea invaded non-communist South Korea across the 38th parallel. It was not simply a Korean civil war in Cold War eyes. The USA saw the invasion as evidence that communism might expand by force if it was not resisted. The Soviet Union and communist China were linked to North Korea, while the USA led a United Nations force to defend South Korea.

The war moved through four broad stages:

The impact was huge. First, the USA became more willing to spend heavily on defence. NSC-68, a U.S. policy paper calling for a major build-up against communism, gained force after Korea. Second, NATO became more than a paper alliance. Western leaders worried that if communism could attack in Korea, a similar attack might happen in Europe. This helped drive the creation of stronger NATO command structures and made the rearmament of West Germany seem more acceptable to the West. Third, Korea encouraged both superpowers to read regional conflicts as tests of their strength.

Korea also taught a cautionary lesson. The USA did not attack the Soviet Union directly, and the Soviet Union did not openly fight the USA as a declared combatant. Both sides feared that total war could become nuclear war. So Korea made containment more military, but it also showed the limits of what either side dared to do.

Misconception check: the Korean War did not "solve" the Cold War in Asia. It left Korea divided, hardened U.S. anti-communism, and strengthened the idea that local wars could have global significance.

When explaining containment, connect the location and conduct of war to the commitments leaders thought necessary.

Warsaw Pact and Co-existence

By the mid-1950s, the Cold War in Europe had become more formally divided. In 1955 West Germany joined NATO. To the USA and its allies, West German rearmament helped defend Western Europe. To the Soviet Union, it looked like a serious threat: Germany had invaded Russia twice in the twentieth century, and now the western half of Germany was inside an anti-Soviet alliance.

The Soviet response was the Warsaw Pact, formed on 14 May 1955. Its members included the Soviet Union and its Eastern European allies, including Poland, Hungary, Czechoslovakia, Romania, Bulgaria, Albania, and East Germany. On paper, it was a mutual defence alliance. In practice, it confirmed that Eastern Europe was a Soviet-controlled military bloc.

The Warsaw Pact mattered for three reasons:

At the same time, Soviet leadership changed. Stalin died in 1953, and Nikita Khrushchev gradually emerged as the leading figure in the Soviet Union. Khrushchev used the phrase peaceful co-existence to argue that communist and capitalist states could avoid direct war. He did not mean that the USSR would stop competing with the USA. He meant that the struggle could continue through diplomacy, propaganda, economic competition, alliances, and nuclear deterrence rather than open superpower war.

This was a shift from the harshest Stalin-era mood, but it was not peace. Khrushchev still believed communism would triumph. He also wanted the USSR to appear confident and modern, especially as nuclear weapons made direct war terrifying. The Geneva Summit of 1955 and Khrushchev's visit to the USA in 1959 suggested a slightly more open atmosphere. Yet the same decade also saw the Warsaw Pact, the suppression of Hungary, and the missile race.

A useful way to judge Khrushchev is to ask: did peaceful co-existence reduce tension or manage tension? It reduced some language of unavoidable war, but it managed rivalry rather than ending it.

Hungary Under Soviet Rule

Hungary had been brought into the Soviet sphere after the Second World War. By the early 1950s it was ruled by the Hungarian Working People's Party, the ruling communist party, under Matyas Rakosi, a loyal Stalinist. Rakosi used "salami tactics" to destroy opposition slice by slice. Political rivals were removed, the secret police intimidated the population, agriculture was pressured into collectivisation, heavy industry was prioritised, and many Hungarians resented Soviet troops and Soviet influence.

The impact of Soviet rule was political, economic, and cultural.

After Stalin died in 1953, the Soviet leadership briefly allowed a softer course. Imre Nagy became prime minister in Hungary from 1953 to 1955. Nagy was still a communist, but he was more reform-minded than Rakosi. He wanted to reduce forced industrialisation, ease pressure on peasants, release some political prisoners, and improve living standards. This made him popular with many Hungarians who wanted socialism with more national independence and less terror.

Rakosi had remained party leader while Nagy was prime minister; his hard line regained policy dominance in 1955, but the situation changed again in 1956. Khrushchev's secret speech at the Twentieth Party Congress denounced Stalin's abuses and encouraged de-Stalinisation. Across Eastern Europe, people asked an obvious question: if Stalinist terror had been wrong in Moscow, why should Stalinist leaders remain in power in countries like Hungary?
