Coup d’état in São Tomé e Príncipe

This research paper analyzes the military coup in São Tomé e Príncipe on 16 July 2003, examining the interplay between domestic political instability, the grievances of the armed forces, and the influence of former mercenaries from the Buffalo Battalion, while assessing the role of potential oil wealth in the event and its resolution.

• The coup of 16 July 2003 was primarily driven by the demands of the Christian Democratic Front (FDC), a group including former members of the Buffalo Battalion who sought material compensation and 'social reintegration' after years of exile and combat. They partnered with Major Fernando Pereira, who was motivated by the 'deplorable state of the armed forces' and the government's failure to address military grievances.
• While international observers frequently attributed the coup to oil politics, the document argues that potential oil wealth was not the dominant cause, though it likely influenced the timing. The rebels aimed to highlight the 'unequal distribution of the country’s resources' before oil revenues arrived, fearing the government would use future petrodollars to buy off opposition.
• The coup was characterized as 'sui generis' because it was bloodless, did not disrupt ordinary life in the archipelago, and the detained government officials—including Prime Minister Maria das Neves—were treated well, with access to cell phones and visitors.
• The crisis was resolved through international mediation involving eight countries and three inter-state organizations, including the CPLP, AU, and CEEAC. The resulting Memorandum of Understanding reinstated President Fradique de Menezes and provided a general amnesty for the conspirators in exchange for promises to reform the armed forces and improve transparency in the oil sector.
• The intervention of Nigeria, led by President Olusegun Obasanjo, was pivotal in reinstating President Menezes and served to increase Nigeria's regional influence in São Tomé e Príncipe, partly due to the existing Joint Development Zone (JDZ) for oil exploration.
• Prior to the coup, São Tomé e Príncipe experienced significant political instability, characterized by frequent changes in government—eleven since 1991—and disputes over executive powers between the Presidency and the National Assembly.
