The USSR's dictator Joseph Stalin died on 5th March 1953. After a three-year power struggle, Khrushchev took the position of General Secretary of the USSR in 1956. To the world, Khrushchev marked a change in the leadership style of the USSR.

  • At the 20th Party Congress in 1956, Khrushchev denounced Stalin's leadership

    • The three-hour 'Secret Speech' accused Stalin of abusing his power

    • Khrushchev stated the need for 'peaceful co-existence' with the West

  • Khrushchev began a process called 'De-Stalinisation'

    • He released a large number of political prisoners

    • He lifted some censorship of information

    • He increased the number of consumer goods in the USSR

In reality, Khrushchev could not implement too much capitalism and democracy into a communist dictatorship.

  • Hungary's communist leader, Mátyás Rákosi, harshly controlled the country

    • He stated he wanted Hungary to become a 'country of iron and steel'

      • This was despite the fact that Hungary had no iron ore

    • Hungary suffered from fuel shortages and poor harvests

  • In October 1956, there were violent protests in Hungary's capital, Budapest

    • Hungarian students led a peaceful demonstration asking for more political and personal freedom 

      • Hungary's secret police arrested protestors and used tear gas to end the march

      • When the students attempted to free the arrested, the police shot at the protestors

    • Soldiers joined the student protestors

      • The Hungarian Communist government requested military support from the USSR

    • By 24th October, the USSR had restored order in Budapest

  • Khrushchev decided to change the leadership of Hungary

    • He replaced Rákosi with Ernö Gerö

      • Gerö was unpopular and demonstrations occurred in Hungary

      • The USSR allowed a new government to be created under Imre Nagy

  • Khrushchev believed that Nagy would resolve the unrest in Hungary

    • The people liked Nagy

    • Limited reforms would stop Hungarians from protesting

A concept map showing the areas of reform that Nagy attempted to introduce in October-November 1956

  • Khrushchev allowed Nagy some freedom to reform

    • The protests in Hungary made Communism look bad to the West

  • Khrushchev could not accept Hungary’s withdrawal from the Warsaw Pact

    • The USSR needed Hungary to remain in the Warsaw Pact

      • Khrushchev may have needed Hungarian troops to suppress uprisings in other satellite states

      • Hungary's withdrawal may have prompted other satellite states to do the same

      • The USSR relied upon the collective security of pro-Communist states. The satellite states would not protect the USSR if they did not have to 

    • Khrushchev did not want any more independent Communist states in Eastern Europe

      • Yugoslavia, under the leadership of Tito, broke away from the USSR's influence in 1948

      • Yugoslavia became closer to the West by accepting military support from NATO. Tito explored different versions of Communism that undermined the USSR

      • Khrushchev did not want other satellite states to form alliances with Yugoslavia

Khrushchev's Reaction to the Uprising

Khrushchev's Reaction to the Uprising

A flow diagram explaining Khrushchev's reaction and punishment of the Hungarian Uprising. The flowchart states "Khrushchev sent an invasion force of 1,00 tanks to Hungary on 4th November 1956. Nagy and his supporters fought the invasion force. This is called the Hungarian uprising. Nagy contacted the West, begging them to send military assistance to Hungary. The Soviet invasion force brutally attacked the Hungarians. Historians estimate that the invasion force killed 30,000 Hungarians. This ended the uprising. Khrishchev established a stronger communist government in Hungary under the leadership of Janos Kadar. Nagy and members of his government sought refuge in the Yugoslav embassy. Kadar promised Nagy's safety. When Nagy left the embassy, Soviet spies kidnapped him. In July 1958, the Soviet government announced that Nagy had been executed. "

In July 1964, Brezhnev became the Second Secretary. This role essentially placed Brezhnev as Khrushchev's successor. Brezhnev was next in line for the leadership of the USSR. In October 1964, Brezhnev led a coalition against Khrushchev to become the First Secretary of the USSR.

Brezhnev believed that Khrushchev had weakened the USSR

  • Unlike Khrushchev, Brezhnev discussed important decisions with his colleagues 

  • Brezhnev had an authoritarian style of rule, similar to Stalin

Brezhnev marked a change in leadership style. No longer would the USSR allow any type of reform

  • There was a growing desire for change in Czechoslovakia

    • Life in Czechoslovakia was hard. People had limited freedoms and low living standards

    • The Czech government under Gottwald was unpopular with the Czech public

  • In 1968, the Czech Communist Party elected Alexander Dubcek as First Secretary

    • This title gave Dubcek the responsibility of leading the Czech government

    • The USSR approved the appointment of Dubcek

  • Dubcek was a devout Communist. He believed in:

    • The upholding of the Warsaw Pact

    • 'Socialism with a human face’. People in a communist state should be able to:

      • Express their opinion about communism

      • Raise concerns about their government without facing punishment

      • Gain access to a better quality of life

  • In April 1968, the Czech government released a series of reforms. This period of reform is known as the Prague Spring

    • Prague was the capital of Czechoslovakia

    • A 'spring' refers to a period of new beginnings and political reform

A diagram showing the Prague Spring reforms of April 1968, with the central box labeled “The Prague Spring Reforms, April 1968.” Connected to it are multiple surrounding boxes describing the changes considered or introduced during this period. These include: multi-party elections were considered for the future with no date set, relaxation of censorship, freedom to criticise the government without punishment, more power to local governments, reduced government control on Czech industry, increased trade with the West, more opportunities for Czech citizens to travel abroad, more power given to trade unions, and Castro appointed communists into his government.

Brezhnev's Reaction to the Prague Spring

Brezhnev's Reaction to the Prague Spring

  • Brezhnev demanded that Dubcek reverse the Prague Spring reforms

    • Dubcek ignored his request

    • Dubcek invited Ceausescu and Tito, the leaders of Romania and Yugoslavia, for talks

      • This appeared to be an aggressive action against the USSR 

      • Brezhnev could not allow Czechoslovakia to unify with non-Soviet Communist states

  • Brezhnev believed that he needed to take urgent action against Dubcek and the Prague Spring reforms

A vertical flowchart describing key events during and after the Soviet invasion of Czechoslovakia in 1968. At the top, the first box states: "On 28th August 1968, 500,000 Soviet troops invade Czechoslovakia. The troops had been provided by members of the Warsaw Pact." The next box reads: "The Czech public do not fight against the Soviet troops. They peacefully protest by standing in front of tanks and giving the Soviet troops flowers. A student protestor, Jan Palach, burns himself to death in the centre of Prague." The third box says: "Dubcek is arrested and sent to Moscow. The Soviet Union order him to reverse the Prague Spring reforms." The final box at the bottom states: "Dubcek returns to Czechoslovakia. The Czech Communist Party replace Dubcek with Husak as First Secretary. Husak’s government reinforce Soviet power in Czechoslovakia, arresting thousands of Czech protestors."
