Slovakia

Socialist-bloc leader 1913–1991 ○ Natural causes after removal

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.

Socialist-bloc leader 1917–2014 ○ Died ; treason case dropped, never convicted

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.

Socialist-bloc leader 1919–1990 ✕ Suicide after the Velvet Revolution

The deputy interior minister who arrested Dubček and handed him to the Soviets

At the 1987 May Day parade in Bratislava, a student threw two eggs at Šalgovič as he stood on the reviewing stand. He had to leave the platform and hand his soiled jacket to a bodyguard.

A Slovak security officer and politician in Czechoslovakia. During the war he deserted from the pro-Nazi Slovak army to the Soviets and served in the Czechoslovak corps; after the war he joined the StB and took part in political repression. In June 1968 Dubček, considering him a personal friend, appointed him deputy interior minister with oversight of the StB. Šalgovič instead coordinated with the KGB, drew up arrest lists for the reformers, and on 21 August handed Dubček and his colleagues to the Soviet occupiers. Under 'normalization' he was shunted to the ceremonial post of chairman of the Slovak National Council (1975–1989); after the Velvet Revolution he hanged himself in the basement of his home.

Socialist-bloc leader 1921–1990 ○ Died after removal

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.
