On May 22, 1988 Janos Kadar was removed as leader of the Hungarian Socialist Workers' Party and replaced by Prime Minister Karoly Grosz, an internal Soviet-bloc party leadership change at a party conference that swept out much of the old guard amid economic difficulties and the Gorbachev reform era. Kadar had led Hungary's communist party since the Soviet suppression of the 1956 revolution, making him one of the longest-serving leaders in the Eastern bloc, and had pursued a comparatively liberal economic course known as Goulash Communism. By 1988, facing mounting economic problems and his own ill health, he came under pressure to step aside.
At a party conference in Budapest on May 22, 1988, at which about half a dozen of his Politburo associates were also removed, Kadar resigned as general secretary and was replaced by Karoly Grosz. Kadar was moved to the ceremonial post of party president.

Janos Kadar, leader of the Hungarian Communist Party since Soviet tanks crushed the 1956 revolution, was relieved of his post as general secretary on Sunday, 22 May 1988, and replaced by Prime Minister Karoly Grosz, an advocate of economic reform, and Kadar was also dropped from the ruling Politburo and made president of the party, a largely figurehead position.

At a party conference in Budapest on 22 May 1988, at which half a dozen of his Politburo associates were also removed, Kadar announced his resignation and was officially replaced as General Secretary by Prime Minister Karoly Grosz, who strove to continue Kadar's policies in a modified form, while Kadar was named to the ceremonial position of Party President.
Kadar resigned under pressure as General Secretary in the face of mounting economic difficulties and his own ill health, in what one scholar called an apparat coup by the party apparatus on 22 May 1988 that resulted in the wholesale replacement of the Politburo, orchestrated by Prime Minister Grosz and his personal coterie.
Kadar was the second of the aging East bloc leadership to step down since reform began with the rise of Gorbachev in 1985, coming after Czechoslovak party leader Gustav Husak stepped down the previous November, and until his ouster Kadar had been the second longest-serving party leader in the East Bloc after Todor Zhivkov of Bulgaria.

Editorial Note
Coding note and dataset examination: the dataset labels this a palace coup with a not-physically-harmed fate. In substance this was an internal Communist Party leadership change, the removal of the long-serving general secretary Janos Kadar and his replacement by Karoly Grosz at a party conference; one scholarly source explicitly calls it an apparat coup or palace coup by the party apparatus, supporting the dataset's palace-coup label, though it was a bloodless intra-party maneuver rather than a seizure by force. The record enriches it as coded while making the mechanism explicit. Fate coding: Kadar was not physically harmed and was moved to the ceremonial post of party president, matching the dataset. Context recorded: the change came amid mounting economic difficulties and Kadar's ill health, in the Gorbachev reform era, and the conference also removed about half a dozen of his Politburo associates. Historical weight recorded: this is one of the Soviet-bloc leadership changes tracked in this enrichment (paired with the Czechoslovakia December 1987 record); Kadar had led since the crushing of the 1956 revolution and had pursued the comparatively liberal Goulash Communism. Arc forward: Grosz served only about a year before the 1989 fall of communism in Hungary, later context. Neutrality maintained.
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: Janos Kadar, replaced as Hungarian party leader on May 22, 1988 by Karoly Grosz; he was not harmed and was moved to the ceremonial post of party president..
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.
