Warsaw Pact invasion of Czechoslovakia

On 20–21 August 1968, the Czechoslovak Socialist Republic was jointly invaded by four Warsaw Pact countries: the Soviet Union, the Polish People's Republic, the People's Republic of Bulgaria and the Hungarian People's Republic. The invasion stopped Alexander Dubček's Prague Spring liberalisation reforms and strengthened the authoritarian wing of the Communist Party of Czechoslovakia (KSČ).

"Invasion of Czechoslovakia" redirects here. For the events of 1938–1945, see Occupation of Czechoslovakia (1938–1945).

About 250,000 Warsaw Pact troops (afterwards rising to about 500,000), supported by thousands of tanks and hundreds of aircraft, participated in the overnight operation, which was code-named Operation Danube. The Socialist Republic of Romania and the People's Republic of Albania refused to participate,[13][14] while East German forces, except for a small number of specialists, were ordered by Moscow not to cross the Czechoslovak border just hours before the invasion[15] because of fears of greater resistance if German troops were involved, due to public perception of the previous German occupation three decades earlier.[16] 137 Czechoslovaks were killed[10] and 500 seriously wounded during the occupation.[11]


Public reaction to the invasion was widespread and divided, including within the communist world. Although the majority of the Warsaw Pact supported the invasion along with several other communist parties worldwide, Western nations, along with socialist countries such as Romania, and particularly the People's Republic of China and People's Republic of Albania condemned the attack. Many other communist parties also lost influence, denounced the USSR, or split up or dissolved due to conflicting opinions. The invasion started a series of events that would ultimately pressure Brezhnev to establish a state of détente with U.S. President Richard Nixon in 1972 just months after the latter's historic visit to the PRC.

United States[edit]

The United States and NATO largely ignored the situation in Czechoslovakia. Whilst the Soviet Union was concerned about the possibility of losing a regional ally and buffer state, the United States did not publicly seek an alliance with the Czechoslovak government. President Lyndon B. Johnson had already involved the United States in the Vietnam War and was unlikely to be able to drum up support for a conflict in Czechoslovakia. Also, he wanted to pursue an arms control treaty with the Soviets, SALT. He needed a willing partner in Moscow in order to reach such an agreement, and he did not wish to risk that treaty over what was ultimately a minor conflict in Czechoslovakia.[58][59] For these reasons, the United States stated that it would not intervene on behalf of the Prague Spring.

Reactions in Czechoslovakia[edit]

Popular opposition was expressed in numerous spontaneous acts of nonviolent resistance. In Prague and other cities throughout the republic, Czechs and Slovaks greeted Warsaw Pact soldiers with arguments and reproaches. Vladimir Bogdanovich Rezun, then a junior officer who led a Soviet Tank column during the invasion, was given absurd information from his commanders about how the people of Czechoslovakia would welcome them as their "Liberators", and were instead attacked by angry crowds of people who threw stones, eggs, tomatoes, and apples upon crossing into Slovakia.[74] Every form of assistance, including the provision of food and water, was denied to the invaders. In an opposite case of subterfuge, Rezun recalled how local townspeople quietly opened the gates of the Czech breweries and spirit factories for the enlisted Soviet soldiers, making entire units inebriated and causing significant disruptions to the fury of the Soviet commanders.[75] Signs, placards, and graffiti drawn on walls and pavements denounced the invaders, the Soviet leaders, and suspected collaborationists. Pictures of Dubček and Svoboda appeared in the streets. Citizens gave wrong directions to soldiers and even removed street signs (except for those giving the direction back to Moscow).[76]


Initially, some civilians tried to argue with the invading troops, but this met with little or no success. After the USSR used photographs of these discussions as proof that the invasion troops were being greeted amicably, secret Czechoslovak broadcasting stations discouraged the practice, reminding the people that "pictures are silent".[77] The protests in reaction to the invasion lasted only about seven days. Explanations for the fizzling of these public outbursts mostly centre on demoralisation of the population, whether from the intimidation of all the enemy troops and tanks or from being abandoned by their leaders. Many Czechoslovaks saw the signing of the Moscow Protocol as treasonous.[78] Another common explanation is that, due to the fact that most of Czech society was middle class, the cost of continued resistance meant giving up a comfortable lifestyle, which was too high a price to pay.[79]


The generalised resistance caused the Soviet Union to abandon its original plan to oust the First Secretary. Dubček, who had been arrested on the night of 20 August, was taken to Moscow for negotiations. It was agreed that Dubček would remain in office, but he was no longer free to pursue liberalisation as he had before the invasion.


On 19 January 1969, student Jan Palach set himself on fire in Wenceslas Square in Prague to protest the renewed suppression of free speech.


Finally, on 17 April 1969, Dubček was replaced as First Secretary by Gustáv Husák, and a period of "Normalization" began. Pressure from the Soviet Union pushed politicians to either switch loyalties or simply give up. In fact, the very group that voted in Dubček and put the reforms in place were mostly the same people who annulled the program and replaced Dubček with Husák. Husák reversed Dubček's reforms, purged the party of its liberal members, and dismissed the professional and intellectual elites who openly expressed disagreement with the political turnaround from public offices and jobs.

consolidate the Husák leadership and remove the reformers from leadership positions;

revoke or modify the laws which were enacted by the reform movement;

reestablish ;

centralized control over the economy

reinstate the power of police authorities; and

expand Czechoslovakia's ties with other socialist nations.
