Czech journalist who chaired the Revolutionary Governing Council of the Slovak Soviet Republic in 1919
Born in Nymburk, he was originally an engine fitter; he joined the Social Democratic Party in 1895 and from 1906 was a workers’ journalist and an official of workers’ associations. Living in Budapest from 1918 as a correspondent of the Kladno paper Svoboda, he led the Czech and Slovak section of the Hungarian Communist Party’s central committee in 1919. After the Hungarian Red Army entered Slovakia he proclaimed the Slovak Soviet Republic in Prešov and became chairman of its Revolutionary Governing Council, but the state ceased to exist on 7 July when Czechoslovak troops pushed the Hungarians out. Imprisoned in Hungary after the fall of the Hungarian Soviet Republic, he was handed over to the Czechoslovak authorities in 1920. Granted Soviet citizenship, he moved to Soviet Russia in 1922 and worked for International Workers’ Aid. He died of natural causes in 1941.

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.

Pro-Soviet Social Democrat and first post-liberation premier who sided with the Communists in 1948 and merged his party into theirs
During the Communist coup of February 1948, he led the Social Democratic push for union with the Communists; the merger later that year brought his party into the one-party system.
A diplomat from Olomouc, he served as envoy to the Netherlands, Romania, the United States, Switzerland and Austria and, as the exile government’s ambassador in Moscow during the war, grew close to the Soviet Union. Prime minister of the Košice government from April 1945, he led the National Front government until June 1946. As Social Democratic leader he advocated close co-operation with the Communists, and when the non-Communist ministers resigned in February 1948 he stayed and openly backed the Communists. After the coup he merged the Social Democrats into the Communist Party and held high office under the regime.

A national hero of two world wars who became an unlikely last bastion of the Prague Spring
In Moscow in August 1968, when Brezhnev demanded he install a 'workers'-peasants' government,' Svoboda replied that he would put a bullet in his own head unless Dubček and the reformist leaders were released.
A World War I veteran who deserted the Austro-Hungarian army for the Czechoslovak Legion, Svoboda organized the 1st Czechoslovak Army Corps in the USSR during World War II and emerged a national hero, liberating his homeland from the east. As Minister of Defense, he declared in February 1948 that 'the army will not march against the people,' enabling the Communist takeover, only to be purged and spend the 1950s imprisoned and in obscurity. Elected president in March 1968 on Dubček's recommendation, he consented to the Prague Spring reforms; after the Warsaw Pact invasion that August, he flew to Moscow and threatened to shoot himself in Brezhnev's presence unless the kidnapped reform leaders were freed. During normalization he passively acquiesced to the muzzling of the press and Dubček's removal, remaining in office until a constitutional provision forced him out in 1975.

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.

Chief designer of Soviet nuclear reactors
In January 1946, Kurchatov told him at their first meeting: "We must create an industrial uranium 'boiler' in the shortest possible time." Dollezhal devoted the rest of his life to reactor design.
An engineer of Czech descent, he was the Soviet Union's chief reactor designer, responsible for the reactors that powered the atomic bomb, the first nuclear power plant, and the nuclear submarine fleet. After meeting Igor Kurchatov in 1946, he designed the A reactor for plutonium production, enabling the first Soviet nuclear test in 1949, and built the AM-1 reactor at Obninsk, the world's first grid-connected nuclear power plant (1954). As founding director of NIKIET for 34 years, he developed the prototypes of every major Soviet reactor line — VVER, RBMK, and naval propulsion — making him a foundational figure of the Soviet atomic establishment. In the aftermath of the Chernobyl disaster, his role in the RBMK design drew sharp criticism, and he stepped down as director in 1986.

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.

Husák's right hand who ran the normalization cabinet for eighteen years, then fell backing Gorbachev's perestroika
Asked why he lost, Štrougal answered: 'I underestimated the dissidents.'
A Czechoslovak communist politician who served as prime minister from January 1970 to October 1988: the face, alongside Gustáv Husák, of the 'normalization' regime that crushed the Prague Spring. A law graduate and career party functionary, he rose through the agriculture and interior ministries to become deputy premier under Dubček; after the 1968 Warsaw Pact invasion he abandoned his initial reservations and joined Husák's anti-reform camp, replacing Oldřich Černík as premier. Over eighteen years he cultivated a reputation as a pragmatic technocrat, and in the late 1980s his sympathy for Gorbachev's perestroika brought him into conflict with hard-line party chief Miloš Jakeš, who forced him out. Expelled from the KSČ after the Velvet Revolution, he was prosecuted in old age over Iron Curtain deaths; the case was halted by dementia, and he died in 2023 at ninety-eight.

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.

The Czech novelist who insisted the Prague Spring was a universal attempt to reconcile socialism with freedom
From 'The Czech Fate' in Listy, December 1968: "The Prague Spring moved Czechs and Slovaks to the center of world history… the nation had beheld its own greatness."
A Czech-French novelist. He joined the Communist Party in his youth and was expelled twice; his speech demanding an end to censorship at the 1967 Writers' Congress opened the intellectual prelude to the Prague Spring. After the Warsaw Pact invasion he published 'Český úděl' ('The Czech Fate'), arguing the Prague Spring held universal significance as an attempt to reconcile socialism and democracy, sparking a fierce polemic with Václav Havel, who called it self-centered megalomania. He went into exile in France in 1975, achieved world fame with The Unbearable Lightness of Being (1984), and died in Paris in 2023.
