Democratic Republic of the Congo, 1975 — military coup attempt

Democratic Republic of the Congo (COD)Central Africa, AfricaJune 18, 1975

Event Summary

The dataset records an attempted military coup in the Democratic Republic of the Congo, then called Zaire, on 18 June 1975, during the entrenched personal dictatorship of President Mobutu Sese Seko, who had ruled since seizing power in 1965 and had built an elaborate cult of authority around himself and his sole party, the Popular Movement of the Revolution. In mid-1975 Mobutu announced that he had uncovered a coup plot against him, arresting a number of senior military officers and accusing them of conspiring, in some accounts with foreign backing, to overthrow the regime. The alleged plotters were tried, and Mobutu used the affair to purge the army and reinforce his grip.

Whether a genuine coup was afoot or the plot was fabricated or exaggerated to justify a purge, in the pattern Mobutu had used since the 1966 Pentecost affair, remains uncertain. Mobutu survived and continued his kleptocratic rule over Zaire until he was finally overthrown by Laurent Kabila's rebellion in 1997.

Editorial Note

Dataset date 18 June 1975 corresponds to Mobutu's announced discovery of a coup plot and the ensuing purge of officers; the day level detail and the question of how genuine the plot was are lightly documented in accessible English sources this session, so specifics are flagged, while the alleged plot, the arrests, and Mobutu's use of it are verified. Continues the DRC/Zaire run, following the 1966 Pentecost and 1967 Stanleyville records in batch 66.

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.
