As the new first secretary of the Communist Party of Czechoslovakia, Dubček was propelled into the role of chief reformer, even though he was not particularly qualified for it. He was a young Slovak who had spent his political life in the party apparat, and, because he was a compromise candidate, people did not expect much from him. Yet in the effort of ridding the government of the old guard, Dubček was aided by the pressure of public opinion, which was growing stronger, especially after members of the press became determined to express themselves more freely in early March 1968.

By April the old apparat had crumbled, and the reformers held sway. Several diehards attempted suicide, but on the whole the transfer of power was peaceful. Oldřich Černík became prime minister, and Šik and Husák became vice premiers in charge of reforms in the economy and Slovakia, respectively. From March 30, Czechoslovakia also had a new president, Ludvík Svoboda, who had been minister of defense in the first postwar government. He had aided the communists during the 1948 coup but was himself purged in the 1950s and had lived in retirement since then. The interior ministry came under the control of another purge victim, Josef Pavel. The newly elected Presidium, the policy-making body of the Czechoslovak Communist Party, consisted largely of newcomers.

The crown achievement of the new reformist government was the Action Program, adopted by the party’s Central Committee in April 1968. The program embodied reform ideas of the several preceding years; it encompassed not only economic reforms but also the democratization of Czechoslovak political life. Among its most important points were the promotion of Slovakia to full parity within a new Czechoslovak federation, long overdue industrial and agricultural reforms, a revised constitution that would guarantee civil rights and liberties, and complete rehabilitation of all citizens whose rights had been infringed in the past. The program also envisaged a strict division of powers: the National Assembly, not the Communist Party, would be in control of the government, which in turn would become a real executive body and not a party branch; courts were to become independent and act as arbiters between the legislative and executive branches. Political pluralism was not recommended, but the Communist Party would have to justify its leading role by competing freely for supremacy with other organizations in the process of formation. International opinion saw Dubček as offering “socialism with a human face.”

The effect of the liberalization movement—which became known as the Prague Spring—on the Czechoslovak public was unprecedented and quite unexpected. Alternative forms of political organization quickly emerged. Former political prisoners founded K 231, a group named after the article of the criminal code under which they had been sentenced; a number of prominent intellectuals formed KAN, a club for committed non-Communist Party members; and there even were efforts to reestablish the Social Democratic Party, forcibly fused with the Communist Party in 1948. With the collapse of the official communist youth movement, youth clubs and the Boy Scouts were resurrected. Christian churches, national minority associations, human rights groups, and other long-forgotten societies became active as well.

On June 27, 1968, the dissident writer Ludvík Vaculík published a document signed by a large number of people representing all walks of Czechoslovak life. This document, dubbed the “Two Thousand Words” manifesto, constituted a watershed in the evolution of the Prague Spring: it urged mass action to demand real democracy. Though shocked by the proclamation, Dubček was convinced that he could control the transformation of Czechoslovakia.

The Soviet Union and the other Warsaw Pact allies were far more alarmed. After Dubček declined to participate in a special meeting of the Warsaw Pact powers, they sent him a letter on July 15 saying that his country was on the verge of counterrevolution and that they considered it their duty to protect it. Nevertheless, Dubček remained confident that he could talk himself out of any difficulties with his fellow communist leaders. He accepted an invitation by Brezhnev to a conference at Čierná-nad-Tisou (a small town on the Soviet border with Slovakia), where the Soviet Politburo and the Czechoslovak leaders tried to resolve their problems. On August 3, representatives of the Soviet, East German, Polish, Bulgarian, Hungarian, and Czechoslovak Communist parties met again at Bratislava; the communiqué issued after that meeting gave the impression that pressure would be eased on Czechoslovakia in return for somewhat tighter control over the press.

However, on the evening of Aug. 20, 1968, Soviet-led armed forces invaded the country. The Soviet authorities seized Dubček, Černík, and several other leaders and secretly took them to Moscow. Meanwhile, the population spontaneously reacted against the invasion through acts of passive resistance and improvisation (e.g., road signs were removed so that the invading troops would get lost). Although communications were disrupted and supplies were held up, the people went on with life at the local level. Even the scheduled 14th Communist Party Congress took place on August 22; it elected a pro-Dubček Central Committee and Presidium—the very things the invasion had been timed to prevent. The National Assembly, declaring its loyalty to Dubček, continued its plenary sessions. On August 23 President Svoboda, accompanied by Husák, left for Moscow to negotiate an end to the occupation. But by August 27 the Czechoslovaks had been compelled to yield to the Soviets’ demands in an agreement known as the Moscow Protocol. Svoboda, bringing with him Dubček and the other leaders, returned to Prague to tell the population what price they would have to pay for their “socialism with a human face”: Soviet troops were going to stay in Czechoslovakia for the time being, and the leaders had agreed to tighter controls over political and cultural activities.

The continued presence of Soviet troops helped the communist hard-liners, who were joined by Husák, to defeat Dubček and the reformers. First of all, the 14th Party Congress was declared invalid, as required by the Moscow Protocol; hard-liners were thus able to occupy positions of power. Czechoslovakia was proclaimed a federal republic, with two autonomous units—the Czech Lands (Bohemia and Moravia) forming the Czech Socialist Republic and Slovakia the Slovak Socialist Republic, respectively—each with national parliaments and governments. A federal arrangement was the one concession the hard-liners were ready to make, and, indeed, many citizens (particularly the Slovaks) had desired it. Nonetheless, protests against the curtailing of reforms—such as the dramatic suicide of Jan Palach, a student who on Jan. 16, 1969, set himself on fire—were what held the country’s attention.

Gradually, Dubček either dismissed his friends and allies or forced them to resign, and on April 17, 1969, Husák replaced him as first secretary. Dubček continued for a while as chairman (speaker) of the parliament and then became ambassador to Turkey. After his recall in 1970 he was stripped of his party membership. The victorious Husák declared the Dubček experiment to be finished and promptly initiated a process of “normalization.”

“Normalization” and political dissidence

As first secretary, Husák patiently tried to persuade Soviet leaders that Czechoslovakia was a loyal member of the Warsaw Pact. He had the constitution amended to embody the newly proclaimed Brezhnev Doctrine, which asserted the right of the Soviet Union to intervene militarily if it perceived socialism anywhere to be under threat, and in 1971 he repudiated the Prague Spring—declaring that “in 1968 socialism was in danger in Czechoslovakia, and the armed intervention helped to save it.” In 1970 Oldřich Černík was finally forced to resign the premiership; he was succeeded by Husák’s Czech rival, Lubomír Štrougal. In 1975, when President Svoboda retired because of ill health, Husák once again fused the two most important offices in Czechoslovakia and became, with full Soviet approval, president himself.

Having purged the reformists during 1969–71, Husák concentrated almost exclusively on the economy. In the short term, Czechoslovakia did not suffer significantly, even from the disruption caused by the military occupation in 1968. The country undertook important infrastructure improvement projects, notably the construction of the Prague metro and a major motorway connecting Prague with Bratislava in Slovakia. Husák, however, did not permit the industrial and agricultural reforms from the Action Program to be applied and so failed to cure the country’s long-term economic problems. The achievements of the mid- to late 1970s were modest, and by the early 1980s Czechoslovakia was experiencing a serious economic downturn, caused by a decline in markets for its products, burdensome terms of trade with several of its supplier countries, and a surplus of outdated machinery and technology.

Although Husák had avoided the bloodletting of his predecessors, his party purges had damaged Czechoslovak cultural and scientific life, since positions in these two areas depended on membership in the party. Numerous writers, composers, journalists, historians, and scientists found themselves unemployed and forced to accept menial jobs to earn a living. Many of these disappointed intellectuals tried to continue the struggle against the regime, but they were indicted for committing criminal acts in pursuance of political objectives. Though these trials could not be compared to the Stalinist show trials, they kept discontent among the intellectuals simmering, even if the mass of the population was indifferent. Intellectual discontent gathered strength in January 1977, when a group of intellectuals signed a petition, known as Charter 77, in which they urged the government to observe human rights as outlined in the Helsinki Accords of 1975. Many intellectuals and activists who signed the petition subsequently were arrested and detained, but their efforts continued throughout the following decade. Among the victims of the crackdown was the philosopher Jan Patocka, who died on March 13, 1977, after a number of police interrogations.

Several mass demonstrations took place in the country during the 1980s. The largest protest gathering in Slovakia since the Prague Spring occurred on March 25, 1988: during this so-called “Candle Demonstration” in Bratislava, thousands of Slovaks quietly held burning candles to show their support for religious freedom and human rights. Police dispersed the demonstration with water cannons and made numerous arrests.
