History in Guinea-Bissau

For the period before the 15th century (15), there is no continuous archaeological chronology for the entire country. Researchers combine archaeological finds with oral history, linguistic research, place names, and later written accounts. From the first millennium onward, agricultural, fishing, and trading societies emerged along the Upper Guinea Coast in river and mangrove environments. This evidence does not support a single unified early history of the country. From the 13th century (13) to the 19th century (19), the influence of Mande-speaking groups from the region of the Mali Empire expanded. The Kaabu polity (Kaabu), also known as N'Gabu, became a significant regional power inland. At the same time, the Balanta, Papel, Manjak and Mankanya, Biafada, Fulbe, Bijagós or Bidiogó, and Felupe and Jola developed different political forms. A simple contrast between state-based and stateless societies does not do justice to these communities. Kaabu's expansion, provincial organization, and chronological boundaries remain disputed; Kansala is regarded as its later capital. Archaeological excavations in 2024 and 2025 point there to a large, planned, and structured site with a royal fortress, provincial forts, and buffer zones, without conclusively clarifying the entire history of Kaabu. Portuguese seafarers reached the coast in the 15th century (15). Initially, trading contacts and coastal outposts emerged, not comprehensive Portuguese rule. Local rulers, merchants, and Afro-European intermediaries (Lançados) and related Afro-European brokers (Tangomãos) controlled access routes and parts of the inland trade. Cacheu became an early Portuguese outpost in 1588. Cacheu, Bissau, Guinala, and other river regions became connected to the Atlantic trade. In the 17th century (17), the Cacheu, Rivers and Guinea Trading Company (Companhia de Cacheu, Rios e Comércio da Guiné) was active. The trade in enslaved people was central; wax, ivory, hides, rice, palm products, and textiles were also traded. Fula and Fulbe jihads, wars over Kaabu, regional Islamization, and shifts in power shaped the 18th and 19th centuries. The collapse of Kaabu at Kansala is generally placed in the middle of the 19th century, although details remain disputed. In the 19th and early 20th centuries (20), France, Portugal, and Great Britain competed for influence. The Bolama dispute was decided in Portugal's favor in 1870. The territory was administered colonially as Portuguese Guinea; Bolama was the capital from 1879 to 1941, followed by Bissau. Effective Portuguese control over the entire territory emerged only through later military and so-called pacification campaigns. The Bijagós Islands were incorporated into the colonial system considerably later. The Estado Novo regime (Estado Novo) remained limited in education and infrastructure and combined administration with tax, coercive, and labor regimes. Colonial records therefore make up a large part of the surviving record, but they often reflect Portuguese administrative, commercial, and military interests. In 1956, Amílcar Cabral and others founded the African Party for the Independence of Guinea and Cape Verde (Partido Africano da Independência da Guiné e Cabo Verde), abbreviated PAIGC. The war for independence lasted from 1963 to 1974. In the areas it controlled, the PAIGC built counter-administrations, schools, health services, and supply structures. Participation, coercion, flight, and cooperation with different sides varied by region. On 24 September 1973, an assembly in Boé declared independence. Portugal legally recognized Guinea-Bissau on 10 September 1974 after the Carnation Revolution and withdrew its troops. This chronological difference is one of the central political and legal questions in interpreting the history of independence. After 1974, the PAIGC dominated state-building with a revolutionary-socialist orientation. In 1980, João Bernardo Vieira overthrew the leadership, Guinea-Bissau and Cabo Verde separated politically, and in 1984 a new constitution described the system as a national revolutionary democracy. Constitutional amendments from 1991 to 1993 enabled political pluralism. In the first multiparty elections in 1994, the PAIGC remained the strongest force, but conflicts between civilian leadership and the military continued. The armed conflict of 1998 and 1999, following the dismissal of General Ansumane Mané, led to interventions by Senegal and Guinea, a peace process involving ECOWAS, and Vieira's overthrow on 7 May 1999. The war severely damaged Bissau, archives, and social continuity. Between 1999 and 2020, further coups, military revolts, murders, and constitutional conflicts followed. UNOGBIS and later UNIOGBIS supported elections, reconciliation, the rule of law, and security-sector reforms; UNIOGBIS ended in 2020. Kumba Yalá was overthrown in 2003, Veríssimo Correia Seabra was murdered and a military revolt ended in 2004, and Vieira returned from exile and was elected in 2005. After the death of General Batista Tagme Na Wai, Vieira was murdered in 2009. Another coup on 12 April 2012 led to sanctions under Resolution 2048. The 2014 elections enabled a return to constitutional order, but repeated conflicts between the presidency, government, parliament, and the PAIGC shaped the years through 2020. The transfer of power after the disputed 2020 presidential election was described by the United States as the first peaceful democratic transfer of power, but it remained constitutionally disputed. After the elections of 23 November 2025, the military high command took power on 26 November, removed President Umaro Sissoco Embaló, and suspended institutions, media, and the electoral process. General Horta Inta-a became transitional president on 28 November. A transition charter provides for a one-year transition period; on 18 May 2026, the African Union called for a return to constitutional order, the release of political prisoners, and political dialogue. Elections were planned for December 2026. This situation does not demonstrate completed democratization. The National Institute for Studies and Research (Instituto Nacional de Estudos e Pesquisa), or INEP, and the National Historical Archive (Arquivo Histórico Nacional), or AHN, support historical research. The AHN holds collections on the precolonial and colonial periods through 1973, on administration after independence, and audiovisual oral history relating to the liberation struggle, dating from its establishment in 1984. Access is generally public under the national archival mandate, but it may be restricted to protect the dignity of individuals and institutions. The war of 1998 and 1999 severely damaged holdings. Digitization projects with the Fundação Mário Soares, the British Library, and European partners, as well as archives in Lisbon and Cabo Verde, help close individual gaps. Medieval Arabic sources provide only limited information about the region. Oral traditions were often recorded late, while colonial reports can be selective and ethnographic in a reductive way. PAIGC and parliamentary narratives, Portuguese records, documents of the United Nations and African Union, and local oral history should therefore be compared with one another. The memories of veterans, civilians, Fulbe, Balanta, Bijagós, and other communities, as well as war victims, may differ. The history of Guinea-Bissau does not rest on a fully centralized and continuous national source base; archives, local research, oral history, the archaeology of Kansala, and Portuguese and Cabo Verdean collections together provide the main avenues of access.
