On September 6, 1980 Edward Gierek was removed as First Secretary of Poland's ruling communist party amid the wave of Solidarity strikes, replaced by Stanislaw Kania in a leadership change the party officially attributed to Gierek's ill health. Gierek had led the Polish United Workers' Party (PZPR) since 1970, but by August 1980 mass strikes centered on the Gdansk shipyards had forced the government to concede the right to form independent trade unions, the birth of Solidarity. The upheaval discredited Gierek's leadership.
On September 6, 1980 the party removed him and named Kania, a Politburo member, as his successor; the official statement said Gierek had asked to be relieved for health reasons, echoing the way his own predecessor had been removed in 1970. Gierek was not physically harmed; he was later expelled from the party and briefly interned under martial law.

The Party named Stanislaw Kania, a member of the PZPR Politburo, as Gierek's successor, and in a fashion similar to the 1970 dismissal of Gierek's predecessor and common in Communist nations at the time, the official statement said that Gierek had asked to be relieved of his responsibilities for health reasons.

The upheaval came as striking shipyard workers won concessions in the August 31 agreement, including the right to form independent trade unions, part of the crisis that discredited Gierek's leadership and led to his replacement by Kania.

Gierek would live until 2001, indicating he was not harmed at his removal, which the party framed as a health-related resignation in the standard manner of Communist leadership transitions.

Editorial Note
Coding note: the dataset labels this a palace coup with a not-physically-harmed fate, accurately, as it was an internal party removal of the First Secretary by the PZPR leadership, dressed up in the customary language of a health-related resignation; Gierek was not harmed at the time. Context recorded: the removal was driven by the August 1980 Solidarity strikes and the Gdansk Agreement conceding independent trade unions, a landmark in the erosion of communist rule in Poland, recorded as documented background. Pattern noted: sources observe this mirrored the 1970 removal of Gierek's own predecessor (Gomulka), also amid worker unrest and also framed as a health resignation. Later fate flagged: Gierek was subsequently expelled from the party and interned during the December 1981 martial law crackdown, and he died in 2001; the internment is a separate later event, recorded as flagged aftermath rather than the fate of this September 1980 removal. Arc: this is one of two Communist-bloc palace reshuffles in this batch, alongside China's September 1980 change.
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: First Secretary Edward Gierek, removed on September 6, 1980 and replaced by Stanislaw Kania amid the Solidarity crisis; he was not physically harmed..
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.
