Guinea, officially the Republic of Guinea, is a coastal country located in West Africa. It borders the Atlantic Ocean to the west, Guinea-Bissau to the northwest, Senegal to the north, Mali to the northeast, Ivory Coast to the southeast, and Sierra Leone and Liberia to the south. It is sometimes referred to as Guinea-Conakry, after its capital Conakry, to distinguish it from other territories in the eponymous region, such as Guinea-Bissau and Equatorial Guinea. At the census held on 1 July 2025, Guinea had a population of over 17.5 million and an area of 245,857 square kilometres (94,926 sq mi).
Formerly French Guinea, it achieved independence in 1958. Guinea has a history of military coups d'état. After decades of authoritarian rule, it held its first democratic election in 2010. As it continued to hold multi-party elections, the country still faces ethnic conflicts, corruption, and abuses by the military and police. In 2011, the United States government claimed that torture by security forces and abuse of women and children (including female genital mutilation) were ongoing human rights issues. In 2021, a military faction overthrew president Alpha Condé and suspended the constitution.
Guinea is a member of United Nations, ECOWAS, South Atlantic Peace and Cooperation Zone, Organisation of Islamic Cooperation, La Francophonie, and African Union. Its membership in the African Union was suspended in 2021 because of the 2021 coup, but it was reinstated in January 2026. Muslims represent 90% of the population. The country is divided into four geographic regions: Maritime Guinea on the Atlantic coast, the Fouta Djallon or Middle Guinea highlands, the Upper Guinea savannah region in the northeast, and the Guinée forestière region of tropical forests. French, the official language of Guinea, is the language of communication in schools, government administration, and the media. More than 24 indigenous languages are spoken, and the largest are Susu, Pular, and Maninka, which dominate respectively in Maritime Guinea, Fouta Djallon, and Upper Guinea, while Guinée forestière is ethnolinguistically diverse. Guinea's economy is mostly dependent on agriculture and mineral production. It is the world's second-largest producer of bauxite and has deposits of diamonds and gold. As of the most recent survey in 2018, 66.2% of the population is affected by multidimensional poverty, and an additional 16.4% are vulnerable to it.
Guinea is named after the Guinea region, which lies along the Gulf of Guinea. It stretches north through the forested tropical regions and ends at the Sahel. The English term "Guinea" comes directly from the Portuguese word Guiné which emerged in the mid-15th century to refer to the lands inhabited by the Guineus, a generic term for the African peoples south of the Senegal River, in contrast to the "tawny" Zenaga Berbers above it, whom they called Azengues or Moors.
In 1978, the official name became the "People's Revolutionary Republic of Guinea". In 1984, the country was renamed the "Republic of Guinea" after the death of the first president, Ahmed Sékou Touré.
The land that is now Guinea either bordered or was situated within a series of historic African empires before the French arrived in the 1890s and claimed the terrain as part of colonial French West Africa. Guinea declared independence from France on 2 October 1958. From independence until the presidential election of 2010, Guinea was governed by multiple autocratic rulers.
West African empires and kingdoms
What is now Guinea sat on the fringes of various West African empires. The earliest, the Ghana Empire, grew on trade and ultimately fell after repeated incursions of the Almoravids. It was in this period that Islam first arrived in the region by way of North African traders. The Sosso Empire came and stayed from the 12th to 13th centuries; later, the Mali Empire came when Soundiata Kéïta defeated the Sosso ruler Soumangourou Kanté at the Battle of Kirina in c. 1235. The Mali Empire was ruled by Mansa (Emperors), including Kankou Moussa, who made a hajj to Mecca in 1324. After his reign, the Mali Empire began to decline and was ultimately supplanted by its vassal states in the 15th century.
The Songhai Empire expanded its power in about 1460. It continued to prosper until a civil war, over succession, followed the death of Askia Daoud in 1582. The empire fell to invaders from Morocco in 1591, but the kingdom later split into smaller kingdoms. After the fall of some of the West African empires, various kingdoms existed in what is now Guinea. Fulani Muslims migrated to Futa Jallon in Central Guinea, and established an Islamic state from 1727 to 1896 with a written constitution and alternate rulers. The Wassoulou Empire (1878–1898) was led by Samori Toure in the predominantly Malinké area of what is now upper Guinea and southwestern Mali. It moved to Ivory Coast before being occupied by the French.
European traders competed for the Cape trade from the 17th century onward and made inroads earlier. Guinea's colonial period began with French military penetration into the area, and its establishment as a colony on 17 December 1891. As a result of various troubles, France occupied Timbo, the capital of Fouta, in 1896, and a definitive treaty was signed in 1897. The defeat of the armies of Samori Touré, Mansa (or Emperor) of the Ouassoulou state and leader of Malinké descent, in 1898 gave France control of what today is Guinea and adjacent areas. The boundaries of the South Rivers were fixed in 1899.
France negotiated Guinea's present boundaries in the late 19th and early 20th centuries with the British for Sierra Leone, the Portuguese for their Guinea colony (now Guinea-Bissau), and Liberia. Under the French, the country formed the Territory of Guinea within French West Africa, administered by a governor general resident in Dakar. Lieutenant governors administered the individual colonies, including Guinea.
In 1958, the French Fourth Republic collapsed due to political instability and its failures in dealing with its colonies, especially Indochina and Algeria. The French Fifth Republic gave the colonies the choice of autonomy in a new French Community or immediate independence in the referendum of 28 September 1958. Guinea voted overwhelmingly for independence. It was led by Ahmed Sékou Touré, whose Democratic Party of Guinea-African Democratic Rally (PDG) had won 56 of 60 seats in the 1957 territorial elections.
The French later withdrew, and on 2 October 1958, Guinea proclaimed itself a sovereign and independent republic, with Sékou Touré as president. Later, Opération Persil was planned by Jacques Foccart; they planned to create large quantities of forged Guinean francs to hyperinflate Guinea's economy and to arm Touré's opposition figures. However, the operation was leaked, and soon, the Guinean was issuing a number of official complaints.
In 1960, Touré declared the Democratic Party of Guinea the country's only legal political party, and for the next 24 years, the government and PDG were one. Touré was re-elected unopposed to four 7-year terms as president, and every 5 years voters were presented with a single list of PDG candidates for the National Assembly.
On 22 November 1970, Portuguese forces from neighbouring Portuguese Guinea staged Operation Green Sea, a raid on Conakry by several hundred exiled Guinean opposition forces. Among their goals, the Portuguese military wanted to kill or capture Sekou Touré due to his support of PAIGC, an independence movement and rebel group that had carried out attacks inside Portuguese Guinea from their bases in Guinea. After some fighting, the Portuguese-backed forces retreated. Guinea was elected as a non-permanent member of the UN Security Council 1972–73.
In 1977, a declining economy and a ban on all private economic transactions led to the Market Women's Revolt, a series of anti-government riots started by women working in Conakry's Madina Market. Touré vacillated from supporting the Soviet Union to supporting the United States. The late 1970s and early 1980s saw some economic reforms. After the election of Valéry Giscard d'Estaing as French president, trade increased and the two countries exchanged diplomatic visits.
