Comoros, 1987 — dissident coup attempt

Comoros (COM)East Africa, AfricaNovember 30, 1987

Event Summary

The dataset records an event coded as an attempted dissident coup in the Comoros on 30 November 1987 against President Ahmed Abdallah, whose autocratic rule over the Indian Ocean archipelago rested on the Presidential Guard commanded by the French mercenary Bob Denard. In late November 1987 a coup attempt was reportedly mounted by a small number of Presidential Guard and armed forces personnel against Abdallah, and it was thwarted, according to accounts, by the very French mercenaries and South African military advisers based in the Comoros who underpinned the regime. The episode was one of a series of plots and mutinies that punctuated Abdallah's rule, which depended heavily on foreign mercenaries and South African backing in defiance of international isolation.

Abdallah survived this attempt but not for long: in November 1989 he was assassinated in his palace by members of that same Presidential Guard, reportedly on the orders of Denard himself, an act that finally ended his rule and precipitated a French intervention that forced Denard and his mercenaries out of the Comoros.

Editorial Note

Dataset date 30 November 1987 corresponds to the November 1987 plot thwarted by the mercenaries; the exact day is lightly documented in accessible English sources this session and flagged, while the plot, the mercenary role, and Abdallah's 1989 assassination are verified. Second Comoros record in the run, after the March 1985 Presidential Guard mutiny in batch 76.

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.
