Uganda, 1972 — rebel coup attempt

Uganda (UGA)East Africa, AfricaSeptember 17, 1972

Event Summary

The dataset records an event coded as an attempted rebel coup in Uganda on 17 September 1972, corresponding to the invasion launched by Ugandan exiles loyal to the ousted former president Milton Obote, with limited Tanzanian support, to overthrow the regime of Idi Amin. Amin had seized power from Obote in January 1971, and exiles who fled his purges plotted his removal from bases in Tanzania. On 15 to 17 September 1972 a rebel force of around 1,300 ex-soldiers, the People's Army, joined by a guerrilla group under Yoweri Museveni, crossed into southern Uganda hoping to spark a popular uprising.

But the invasion was plagued from the start, Amin had been warned, a planned commando raid was aborted, and the poorly armed rebels were outnumbered. They seized a few southern towns but no mass uprising erupted, and Amin's loyalists defeated them within hours. The failure deepened divisions among the anti-Amin opposition, though many of the same figures would return to topple Amin in the 1979 war.

The operation was hampered from the start as a planned commando raid was aborted, Amin was warned of the impending invasion, and the rebels lacked numbers, training, and equipment.

Editorial Note

Dataset date 17 September 1972 falls within the 15 to 17 September 1972 exile invasion; the dataset codes it a rebel coup with leader unharmed, reflecting the invasion aimed at overthrowing Amin. Well documented. First Uganda record in the dataset run; several of the plotters returned to overthrow Amin in the 1978 to 1979 war.

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.
