Guinea-Bissau, 2012 — dissident coup attempt

Guinea-Bissau (GNB)West Africa, AfricaOctober 21, 2012

Event Summary

The dataset records an event coded as an attempted dissident coup in Guinea-Bissau on 21 October 2012 against the transitional government that had itself been installed by a military coup earlier that year. In April 2012 the army had seized power between the two rounds of a presidential election, detaining the front runner, former prime minister Carlos Gomes Junior, and blocking the vote; under regional pressure, the junta installed a transitional civilian government while the military, dominated by the drug linked general Antonio Indjai, retained real control. On 21 October 2012 an armed group attacked a military barracks near the capital Bissau in what the transitional authorities described as an attempted coup or destabilization aimed at restoring the ousted order, with several people killed in the clash.

The transitional government, backed by the entrenched military leadership, put down the attack. Guinea-Bissau's chronic instability, deeply entangled with its role as a major cocaine trafficking corridor and the military's habitual interference in politics, continued to churn; the country slowly returned to elected government in 2014, but coups, plots, and mutinies would persist for years.

Editorial Note

Dataset date 21 October 2012 corresponds to the barracks attack described as an attempted coup against the post-April-2012 transitional authorities; the precise details are lightly documented in accessible English sources this session and flagged, while the attack and context are verified. Continues the Guinea-Bissau run, after the April 2010 mutiny in batch 85.

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.
