GUINEA-BISSAU: Decades of Coups and the Cost of Political Instability

By Kamal Hammajo | November 27, 2025

Guinea-Bissau has long struggled with a cycle of political instability marked by repeated military interventions. Since the country gained independence from Portugal in 1974, the military has played an outsized role in governance, shaping national politics through coups, attempted coups, and periods of violent upheaval. This persistent interference has significantly undermined the nation’s development and weakened its institutions.

A LEGACY ROOTED IN THE LIBERATION STRUGGLE

At independence, Guinea-Bissau inherited a strong military influence after years of armed struggle led by the African Party for the Independence of Guinea and Cape Verde (PAIGC). The armed forces, having delivered victory on the battlefield, entered the post-independence era with enormous political authority. That authority soon translated into direct intervention.

A HISTORY DEFINED BY COUPS AND CRISIS

The country’s first major coup occurred on 14 November 1980, when then–Prime Minister João Bernardo “Nino” Vieira overthrew President Luís Cabral in a bloodless takeover. Vieira’s new military-led council set a precedent that would influence national politics for decades.

The 1990s saw growing dissent within the military ranks, culminating in a failed coup attempt in 1998 by former army chief Ansumane Mané. The attempt spiraled into a civil war that lasted nearly a year and ended with the ousting of Vieira in 1999.

Another military takeover followed on 14 September 2003, when President Kumba Ialá was removed from office. The armed forces cited economic mismanagement and political disorder. A transitional government was formed under international guidance.

Political tensions resurfaced in 2008 and 2009 with the assassinations of Army Chief Tagme Na Waie and President Vieira, a stark reminder of the deep divisions between political leaders and the security establishment.

On 12 April 2012, the military again seized power during a tense election period, arresting the interim president and front-running candidate. The coup halted the electoral process and forced the intervention of regional bodies.

Although elections in 2014 brought a brief period of relative calm, disputes between civilian leaders and the military continued to fuel instability. The cycle repeated in November 2025, when soldiers took control amid disputed election results, dissolving state institutions and installing a military command.

ECONOMIC CONSEQUENCES OF REPEATED TAKEOVERS

The country’s long history of instability has had severe economic consequences. Frequent coups undermine investor confidence, disrupt development programs, and weaken government capacity. Many international partners hesitate to commit long-term funding to a nation where political outcomes are unpredictable.

Public infrastructure projects are often halted or abandoned following a coup, while donor-funded programs face delays as transitional governments struggle to establish stability. The nation’s persistent poverty, limited industrial growth, and reliance on subsistence agriculture are partly rooted in decades of disrupted governance.

WEAKENING OF STATE INSTITUTIONS

Each military intervention further erodes the authority of civilian institutions. Parliaments, courts, and ministries lose credibility when repeatedly sidelined by armed actors. The military’s political involvement has blurred the lines between security operations and governance, reducing transparency and accountability.

These institutional weaknesses have fuelled a lack of public trust in the state, contributing to voter apathy and political disengagement. The constant turnover in leadership also prevents the implementation of long-term policies needed to address education, healthcare, and economic diversification.

EFFECTS ON GOVERNMENT STABILITY

The continued militarization of politics has made it difficult for any administration to govern effectively. Leaders often struggle to assert their authority without provoking resistance from factions within the armed forces. Political disagreements frequently escalate into national crises due to the absence of strong, independent institutions capable of mediating disputes.

Dissolutions of parliament, contested election results, and power struggles between presidents and prime ministers have become common. Rather than resolving governance challenges, these conflicts have reinforced instability and increased the likelihood of further military intervention.

MOVING TOWARD LASTING STABILITY

Analysts note that lasting peace and development in Guinea-Bissau will depend on comprehensive security sector reforms, stronger democratic institutions, and broader national dialogue aimed at reducing political fragmentation. Ensuring that the military remains a professional, non-political body is widely viewed as essential for restoring constitutional order.

Despite the country’s challenges, regional organizations such as ECOWAS continue to support efforts toward stability, emphasizing the need for transparent governance, credible elections, and respect for the rule of law.

CONCLUSION

Guinea-Bissau’s history of military takeovers has left a lasting imprint on its political and economic landscape. The repeated disruptions have slowed national growth, weakened vital institutions, and created persistent uncertainty. As the nation continues to navigate its future, breaking the cycle of coups and establishing enduring democratic governance remain central to achieving long-term stability and development.
