Mauritania, 1987 — military coup conspiracy

Mauritania (MRT)West Africa, AfricaOctober 22, 1987

Event Summary

This entry is coded 22 October 1987, corresponding to the alleged coup plot by Afro-Mauritanian military officers against the government of Colonel Maaouya Ould Sid'Ahmed Taya, which the Interior Minister announced on 28 October 1987. Taya, who had seized power in a bloodless 1984 coup and pursued Arab-nationalist policies that marginalized the country's black population, faced a plot said to have been organized primarily by Halpulaar (Peul or Fulani) officers, with the government identifying the navy as its chief architect. More than fifty people, almost all from the southern black ethnic groups, were tried for conspiracy by a special tribunal presided over by a senior army officer with no legal training, charged with endangering state security by plotting to depose the government.

One trial ended in the execution of three army lieutenants, with harsh prison sentences for others, and the affair precipitated a wide purge of black officers from the military and civil service. The 22 October 1987 coding sits at this plot, days before its public announcement, at the start of the wider anti-black repression of 1986 to 1992.

Editorial Note

Coded 22 Oct 1987 sits at the plot days before the 28 Oct 1987 public announcement of its discovery. Verified as the October 1987 Afro-Mauritanian officers' plot. First Mauritania record in the run.

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.
