On January 5, 1968 the reformist Slovak communist Alexander Dubcek replaced the hardline Stalinist Antonin Novotny as First Secretary of the Communist Party of Czechoslovakia, the internal party leadership change that launched the Prague Spring. Novotny, who had ruled since 1953 and held both the party leadership and the state presidency, had lost support amid economic stagnation, Slovak resentment of Prague centralism, and pressure from party reformers. At an October 1967 Central Committee session Dubcek and other reformers, including the economist Ota Sik, challenged him openly; Novotny summoned Soviet leader Brezhnev to Prague in December, but Brezhnev, unimpressed by Novotny's weak backing, declined to intervene and effectively acquiesced in his removal.
The Central Committee plenum of January 3 to 5, 1968 voted Novotny out of the party leadership and installed Dubcek unanimously as a compromise candidate. Novotny was allowed to keep the ceremonial state presidency until March 22, 1968, when he resigned in favor of Ludvik Svoboda. Little was expected of Dubcek, but he became the figurehead of the reform movement whose Action Program promised socialism with a human face.

On January 5, 1968 Antonin Novotny, the Stalinist ruler of Czechoslovakia, was succeeded as first secretary by Alexander Dubcek, a Slovak who supported liberal reforms, who in the first months introduced far reaching political and economic reforms including increased freedom of speech, in the brief period of freedom known as the Prague Spring, which the Soviet Union answered with the August 20, 1968 invasion.

Isolated and increasingly powerless after clashing with the Slovaks at the October 1967 Central Committee session and after the Soviets declined his December request to help him regain control, Novotny resigned as first secretary and in January 1968 recommended his Slovak opponent Alexander Dubcek, who was elected unanimously; Dubcek became first secretary on January 5, 1968, and from March 22 Novotny also gave up the presidency to Ludvik Svoboda.
The plenum of the party's central committee convened January 3 to 5, 1968 and voted to remove Novotny from his position as party leader, allowing him to retain the presidency of Czechoslovakia, and voted for Dubcek, sixteen years younger, to become the new leader as a credible compromise candidate who would support reforms and appease Slovak resentments.

Editorial Note
Coding note: the dataset labels this a palace coup because it was an internal party leadership change (Novotny ousted as First Secretary by a Central Committee vote), not an armed seizure; Novotny kept the ceremonial state presidency until March 22, so the not physically harmed fate holds. Paired care: this January 5 record is the start of the Prague Spring; the companion record 1968-08-20 is the Warsaw Pact invasion that crushed it (coded a foreign-backed coup), and the two are distinct dataset events. Arc note: Dubcek was himself removed as First Secretary in April 1969 and replaced by the pro-Soviet Gustav Husak, beginning the era of Normalization.
Cross-Reference
Only one dataset carries it. One of the three reference datasets we check against carries this event; the others do not list it. That is not a contradiction — the datasets cover different periods and use different thresholds — but it means the record has had less outside corroboration.
Identifiers for finding this same event in the other datasets:
Coup Atlas research identifies the target as: Antonin Novotny, removed as First Secretary of the Communist Party on January 5, 1968 and replaced by Dubcek; Novotny was not physically harmed, retained the ceremonial state presidency until resigning it on March 22, 1968..
Baseline coding: Incumbent executive removed from power. Recorded leader fate: deposed; not physically harmed. The baseline file does not name individual targets; researched names are kept in a separate layer.
