Guinea-Bissau, 2000 — military coup attempt

Guinea-Bissau (GNB)West Africa, AfricaNovember 23, 2000

Event Summary

The dataset records an event coded as an attempted military coup in Guinea-Bissau on 23 November 2000 against President Kumba Iala, who had taken office earlier that year after the civil war that ousted Joao Bernardo Vieira, and against the backdrop of a violent power struggle with the country's dominant military figure, Brigadier General Ansumane Mane. Mane, the general whose 1998 revolt had triggered the civil war and who had briefly ruled before elections brought Iala to power, remained the most powerful man in the fractured armed forces and chafed under civilian authority. In late November 2000 the tension exploded: Mane, rejecting a round of military promotions ordered by Iala, declared himself head of the armed forces in what amounted to a coup attempt, plunging Bissau into armed clashes between his loyalists and government troops.

The revolt was crushed within days by forces loyal to Iala, and Mane was killed on 30 November as he fled. Iala survived and consolidated his hold, but his own erratic rule proved short lived; he was overthrown in a bloodless military coup in September 2003, continuing Guinea-Bissau's chronic cycle of instability.

Editorial Note

Dataset date 23 November 2000 corresponds to the late-November 2000 Mane revolt against Iala, which ended with Mane's death on 30 November; the exact start day is lightly documented this session and flagged, while the revolt, its cause, and Mane's death are verified. Continues the Guinea-Bissau run, after the June 1998 Mane coup in batch 82; Mane's final act.
