Guinea-Bissau, 1998 — military coup attempt
Event Summary
On 7 June 1998 Brigadier General Ansumane Mane launched a military revolt against President Joao Bernardo Vieira of Guinea-Bissau, an attempted coup that failed to seize power outright but triggered a devastating year long civil war. The crisis was sparked when Vieira dismissed Mane as armed forces chief of staff, blaming him for an arms smuggling scandal, the supplying of weapons to the Casamance separatist rebels in neighboring Senegal, despite a report implicating Vieira's own presidential guard. The day after his dismissal, Mane rose in rebellion, and his forces, backed by most of the army, seized the Bra barracks and the airport in Bissau and demanded Vieira's resignation and fresh elections.
Vieira, who had ruled since his own 1980 coup, clung to power only with the intervention of some seventeen hundred Senegalese and four hundred Guinean troops sent to prop him up, sparking heavy urban fighting that displaced hundreds of thousands. The war ground on through fragile ceasefires until May 1999, when Mane's forces finally overthrew Vieira, who fled into exile in Portugal.
