Uganda, 1977 — military coup attempt

Uganda (UGA)East Africa, AfricaJune 18, 1977

Event Summary

The dataset records an attempted military coup in Uganda on 18 June 1977, coded with the leader injured, during the final blood soaked years of Idi Amin's dictatorship, when his army was torn by plots, defections, and constant purges. By 1977 Amin's rule had grown ever more paranoid and violent, especially after the February 1977 murder of the Anglican Archbishop Janani Luwum, and there were repeated reports of assassination attempts and mutinies against him, some of which reportedly left Amin wounded. The dataset's coding of the leader as injured reflects one such attempt in mid-1977 in which Amin was said to have been hurt but survived.

Amin weathered these internal challenges through terror and the loyalty of his security units and foreign soldiers, meeting each with fresh executions. His regime was ultimately destroyed not from within but by external invasion, when Tanzanian forces and Ugandan exiles overthrew him in the 1979 war, ending one of the most murderous dictatorships in postcolonial Africa.

Editorial Note

No discrete documentation of a coup attempt precisely on 18 June 1977 in Uganda was found in accessible English sources this session; the entry records the dataset's coding, including the leader injured fate, and the verified context of the plot ridden Amin regime, with the specific event and plotters unconfirmed, flagged as context only. Fifth Uganda record in the run, the last during Amin's rule before his 1979 overthrow.

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.

Outcome and Target

Coup Atlas research identifies the target as: Idi Amin reportedly survived the June 1977 attempt with injury and remained in power until 1979.

Baseline coding: Coup attempt failed to remove the incumbent. Recorded leader fate: remained in office; injured. The baseline file does not name individual targets; researched names are kept in a separate layer.
