Mauritania, 1982 — dissident coup attempt

Mauritania (MRT)West Africa, AfricaFebruary 6, 1982

Event Summary

The dataset records an attempted dissident coup in Mauritania on 6 February 1982 against the military government of President Mohamed Khouna Ould Haidalla, less than a year after he had survived the March 1981 coup attempt. Haidalla's rule remained precarious, threatened by rival factions within the ruling Military Committee for National Salvation, by the fallout from the Western Sahara conflict, and by opposition figures backed from abroad. In February 1982 a further plot against him was uncovered, reportedly led by former heads of state and senior officers, including his predecessors Mustapha Ould Salek and Mohamed Mahmoud Ould Louly, who were accused of conspiring to overthrow the government.

The plotters were arrested before they could act, and Haidalla used the affair to purge suspected opponents and tighten his grip. He survived this and further challenges but was finally overthrown in December 1984, while abroad, by his own army chief of staff and prime minister, Colonel Maaouya Ould Sid Ahmed Taya, who went on to rule Mauritania for two decades.

Editorial Note

Dataset date 6 February 1982 corresponds to a plot uncovered against Haidalla; the day level detail and plotter identities are lightly documented in accessible English sources this session, so specifics are flagged, while Haidalla's rule, the pattern of plots, and his eventual overthrow are verified. Second Mauritania record in the run, after the March 1981 coup in batch 74.
