Uganda, 1975 — military coup attempt

Uganda (UGA)East Africa, AfricaSeptember 9, 1975

Event Summary

The dataset records an attempted military coup in Uganda on 9 September 1975, during the terror ridden rule of Idi Amin, whose army continued to be convulsed by plots, purges, and killings as Amin destroyed real and suspected rivals. By 1975 Amin's regime was internationally notorious for its brutality, and within Uganda the security agencies waged constant bloodletting against officers and civilians alike, while Amin cultivated a grandiose public image, having that year assumed the chairmanship of the Organization of African Unity. This atmosphere of paranoia and violence produced recurrent conspiracies among officers alienated by Amin's rule.

Any coup attempt in September 1975 came within that context and did not unseat Amin, who met every challenge with fresh purges. His regime endured through terror until it was destroyed from outside, when Tanzanian forces and Ugandan exiles overthrew him in the 1979 war, ending one of postcolonial Africa's most murderous dictatorships.

Editorial Note

No discrete documentation of a coup attempt precisely on 9 September 1975 in Uganda was found in accessible English sources this session; the entry records the dataset's coding and the verified context of the plot ridden Amin regime, with the specific event and plotters unconfirmed, flagged as context only. Fourth Uganda record in the run, after the 1972 invasion (batch 69) and the two 1974 records in batch 70.

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.
