A stonemason from Zákolany in Bohemia, he came from the Social Democrats to help found the Communist Party. Arrested under the German occupation, he was held in Pankrác prison and Dresden and from 1940 in Sachsenhausen concentration camp. Back home after liberation he became chairman of the Central Council of Trade Unions and a member of the Communist presidium, and briefly chaired the Constituent Assembly in 1946. He succeeded Gottwald as prime minister in June 1948 when Gottwald became president, and became president himself on Gottwald’s death in 1953. He favoured a more humane rule but was outflanked by Novotný.

National Socialist leader who led the ministers’ resignation in February 1948 and headed the exile Council of Free Czechoslovakia

In February 1948 he resigned with non-Communist ministers in an attempt to halt unconstitutional measures by the Communist interior minister. After the coup, he escaped surveillance to the West and led the political exile movement.

Born to a small tradesman in Tábor in Bohemia, he became a teacher and was mayor of Prague from 1937 to 1939. Arrested after the German occupation, he was held in Dachau and Buchenwald until American troops freed him in 1945. As postwar chairman of the National Socialists he was again mayor of Prague and, after leading the second party in 1946, deputy prime minister. In September 1947 he, Masaryk and Drtina received boxes of explosives. He resigned with the other non-Communist ministers in February 1948, escaped surveillance after the coup and chaired the exile Council of Free Czechoslovakia from 1949 to 1974.

Political and party leadership Czechoslovakia 1896–1953 ○ Natural causes

The communist leader who turned Czechoslovakia into a people's democracy through the February 1948 coup

We are the party of the Czechoslovak proletariat and our supreme chief of staff is indeed Moscow. We go to Moscow to learn from the Russian Bolsheviks how to wring your necks. That grin will be wiped off your faces! Maiden speech in the Czechoslovak National Assembly, 21 December 1929

Born into a poor Moravian peasant household, he helped found the Communist Party of Czechoslovakia (KSČ) in 1921 and became its general secretary in 1929, leading it until his death. A Comintern secretary from 1935 to 1943, he helped shape the Popular Front line, and in May 1945 he returned to Prague as deputy prime minister and National Front chairman. After the KSČ won 38 per cent in the 1946 elections he became prime minister, and following the February 1948 coup he was elected Czechoslovakia's first Communist president on 14 June 1948. As president he drove nationalisation and agricultural collectivisation and instigated the trials of Milada Horáková, executed in 1950, and of Rudolf Slánský and Vlado Clementis, executed in 1952; he died on 14 March 1953.

KSČ General Secretary who organized the February 1948 coup and built Czechoslovakia's people's democracy as its operational architect

In September 1947 Slánský returned from the Cominform founding meeting with Moscow's directive to seize power. 'As in the international field, we have gone on the offensive on the domestic front as well' — the February 1948 coup had begun.

After joining the KSČ Central Committee and Politburo in 1929, he rose as Gottwald's closest lieutenant. During WWII he directed Czechoslovak broadcasts from Moscow and fought in the 1944 Slovak National Uprising. As General Secretary (1945–1951), he mastered the party apparatus and directed the operational work of the February 1948 coup, converting Czechoslovakia into a Soviet-aligned people's democracy. Arrested in 1951, he was tried and executed in 1952 on charges of conspiracy, Trotskyism, Titoism and Zionism: the most distinctly antisemitic purge trial in the Eastern Bloc. Rehabilitated 1963; party membership restored 1968.

The Czechoslovak leader whose Stalinist orthodoxy was swept aside by the Prague Spring reform movement

In an impromptu interview after the 1965 May Day parade, Novotný declared, "Meat will be shortly!" (Maso bude vbrzku!). Across the country, Czechs asked, "Where on the map is this 'Shortly'?" — and the nation laughed.

A locksmith and KSČ charter member from 1921, Novotný rose through the party apparatus during the Slánský purge and emerged from the succession struggle after Gottwald's death to rule Czechoslovakia for fifteen years as First Secretary (1953–1968) and President (1957–1968). His regime enforced Stalinist orthodoxy (central planning, censorship, and a refusal to reckon with the show trials of the 1950s) even as economic stagnation and Slovak resentment eroded its foundations. His forced resignation in January 1968, replaced by Alexander Dubček, removed the greatest obstacle to reform and directly precipitated the Prague Spring. Reelected to the Central Committee under normalization in 1971, he died in Prague in 1975 without recovering real influence.

The only Prague Spring leader who refused to sign the Moscow Protocol

In Moscow, standing before Brezhnev, Kriegel said: 'Send me to Siberia or shoot me dead. I will not sign.'

Czechoslovak communist politician and physician. He served as a doctor with the International Brigades in the Spanish Civil War, then rose to become a KSČ Presidium member and chairman of the National Front during the 1968 Prague Spring, where he was among the most radical reformers. Arrested with Dubček on 21 August and deported to Moscow, he was the only one of twenty-six Czechoslovak politicians who refused to sign the Moscow Protocol. Expelled from the party and stripped of his medical license, he became a dissident and was among the first to sign Charter 77 in 1977.

The purge victim who returned to become the Prague Spring's most eloquent reformer

After signing the Moscow Protocol, Smrkovský alone addressed the nation while his colleagues fell silent. Brezhnev singled out his speech as unacceptable.

A Czechoslovak reform communist and Dubček's most important political ally during the Prague Spring. As vice-chairman of the Czech National Council, he led the Prague uprising of May 1945; in February 1948 he commanded the People's Militias to secure the communist takeover. Arrested in 1951 and sentenced to life imprisonment in the Slánský trials, he was released in 1955, fully rehabilitated in 1963, and became chairman of the National Assembly in April 1968, where his oratory made him, alongside Dubček, the most popular politician of the reform era. Deported to Moscow after the August invasion and forced to sign the Moscow Protocol, he was purged by Husák, expelled from the party in 1970, and died under police surveillance in 1974.

Political and party leadership Czechoslovakia 1913–1991 ○ Natural causes

Czechoslovakia's longest-serving leader, who crushed the Prague Spring and built 'normalization'

On 10 December 1989, Husák swore in the first non-communist majority government in 41 years — and resigned the presidency hours later, personally witnessing the formal end of the regime he had built.

A Slovak communist lawyer, he served in the leadership of the 1944 Slovak National Uprising against the Nazis. After the war he consolidated communist rule in Slovakia, but was purged in 1950 for 'bourgeois nationalism' and imprisoned for a decade. Rehabilitated in 1963, he became vice-premier during Dubček's Prague Spring, then reversed after the Soviet invasion to lead the purge of reformers. As KSČ general secretary (1969–1987) and president (1975–1989), he presided over 'normalization': combining relative material stability with secret-police suppression of dissent. He resigned during the 1989 Velvet Revolution, handing power to the first non-communist government in 41 years.

Political and party leadership Czechoslovakia 1917–2014 ○ Died

The party ideology secretary who signed the letter inviting Soviet tanks into his own country

Charged with treason, Biľak denied signing any invitation: "I never wrote to Brezhnev." The letter had been addressed to the CPSU Central Committee, not to Brezhnev personally. A defense that was technically true and entirely beside the point.

A neo-Stalinist of Rusyn origin who rose from tailor to the Presidium of the Czechoslovak Communist Party. In 1968 he was a core member of the conservative 'healthy forces': one of five who signed the invitation letter urging the Warsaw Pact to intervene against the Prague Spring reforms with 'all means at your disposal.' As the KSČ ideology secretary under Husák, he drafted 'Lessons from the Crisis Development' (1970), the doctrinal foundation of normalization that branded the reforms a counter-revolution and justified mass purges, remaining an unreconstructed hardliner until expelled during the Velvet Revolution.

The KSČ hardliner who signed the letter inviting Soviet intervention to end the Prague Spring

On the morning of 21 August 1968, Dubček was arrested 'in the name of the Workers' and Peasants' Government led by Comrade Indra.' But Indra's cabinet never materialized for a single day, and the invitation letter he signed would remain secret until the 1990s.

A neo-Stalinist politician of the Czechoslovak Communist Party. A core conservative during the 1968 Prague Spring, he was one of five who signed the 'invitation letter' urging the Warsaw Pact to intervene, and was designated head of a Soviet-backed 'workers' and peasants' government' immediately after the invasion. Under Husák he remained in the Presidium and chaired the Federal Assembly, driving the 'normalization' purges until expelled by the Velvet Revolution in 1989; he died the following year.

He dreamed of a human face, and was posted to the forestry service

Before dawn on August 21, 1968, Soviet officers burst into Dubček's office. The phone lines were cut, handcuffs went on. 'We will kill, if necessary, a million Czechs, to put an end to your counter-revolution,' an officer said.

The Slovak reform communist who led the Prague Spring. Raised in the USSR from childhood, he abolished censorship in 1968 and pursued 'socialism with a human face', only to be deposed by the Warsaw Pact invasion and spend fifteen years as a forestry clerk. In 1989 he stood beside Havel on the balcony once more.

The ideology cadre who drafted the Action Programme, then served normalization to the end

In early 1968, in his Questions of Peace and Socialism office in Prague, Auersperg set the drafting group to work: Mlynář, Richta, Šik, and the others writing the Action Programme chapter by chapter.

A KSČ ideology cadre who personally wrote Part V of the Action Programme and led the working group that produced the defining document of the Prague Spring. He built his career as Antonín Novotný's secretariat chief, then as head of the party's Ideological Department from 1965, where he enforced censorship over culture and scholarship with a hard hand. In early 1968 he hosted the drafting team in his Questions of Peace and Socialism office and delivered the text adopted on 5 April. After the Warsaw Pact invasion, he broadcast for the pro-Soviet radio from Dresden and served Husák's normalization regime as head of international politics and, ultimately, as ambassador to the Netherlands.

A reform communist who sought to democratize socialism

Recalling a 1967 visit in which he laid his reform plans before his old roommate Gorbachev, Mlynář said: 'It seemed to me he understood very well what I was talking about.'

Zdeněk Mlynář was a Czechoslovak Communist politician and lawyer who sought to join socialism to democratic control and active citizenship. During the Prague Spring of 1968, he served as a Central Committee secretary, worked in Alexander Dubček's reform leadership, and helped shape the political and legal team that drafted the Action Programme. After the Warsaw Pact invasion he signed the Moscow Protocols, then confronted the limits of reform and the reality of occupation by resigning his posts and later leaving the party. He signed Charter 77 and emigrated to Austria, where he became a political scientist and an important interpreter of the Prague Spring.
