Chapter 01 · Prehistory – c. 1000 CE
Forest peoples and the Bantu migrations
The equatorial forest of the Ogooué basin was home to hunter-gatherers such as the Babongo, then to Bantu-speaking farmers and ironworkers whose passage left rock engravings and settlement sites preserved in the Lopé-Okanda landscape.
The earliest known inhabitants of what is now Gabon were rainforest hunter-gatherers, the ancestors of peoples such as the Babongo, Baka, Bakola and related groups often grouped together as forest "Pygmies." They lived by hunting, fishing and gathering in the dense equatorial forest, and over time entered into long-standing exchange relationships with farming neighbours, trading meat, honey and forest products. Their presence in the wider Central African forest reaches back many millennia, long before the spread of farming and metalworking.
From the first millennium BCE, and intensively through the first millennium CE, Bantu-speaking peoples moved into the region as part of the vast Bantu expansion that carried agriculture, pottery and ironworking across Central, Eastern and Southern Africa from a homeland near the present Nigeria–Cameroon border. The valley of the Ogooué River — Gabon's principal waterway, running from the southeast to the Atlantic — served as a natural corridor for this migration around the northern fringes of the Congo Basin forests, and successive groups settled its banks, savannas and forest margins.
This deep history is recorded with unusual clarity in the Lopé-Okanda area of central Gabon, where the forest meets relict savanna along the Ogooué. The landscape preserves an exceptional density of habitation sites, evidence of iron-working, and some 1,800 rock engravings (petroglyphs), testifying to the successive passage of different peoples over a very long period. In 2007 UNESCO inscribed the Ecosystem and Relict Cultural Landscape of Lopé-Okanda as a mixed natural and cultural World Heritage Site, citing it as evidence of the Ogooué valley's role as a major route of human migration.
“The Ogooué valley was a crucial corridor for the migration of Bantu peoples around the fringes of the Congo Basin forests.”

Chapter 02 · c. 1000 – 1840
The Myènè coast, the Fang, and the Atlantic trade
Myènè-speaking peoples such as the Mpongwe and Orungu settled the estuary and rivers and, after Portuguese ships named the coast Gabão in 1472, became middlemen in a trade in ivory, dyewoods and enslaved people linked to Orungu and Loango.
From around the start of the second millennium CE, Myènè-speaking Bantu peoples settled the Gabon coast and lower rivers. The Mpongwe established themselves around the estuary (the Gabon Estuary, or Komo) near the future site of Libreville; the Orungu settled at Cape Lopez, where the Ogooué reaches the sea; and the Nkomi occupied the Fernan Vaz lagoon to the south. Organised in clans under chiefs and councils of elders, these coastal communities were well placed to act as intermediaries between the interior and the sea. The Fang, who would become Gabon's largest ethnic group, were a later arrival, migrating into northern and central Gabon largely in the eighteenth and nineteenth centuries.
European contact began in 1472, when Portuguese navigators reached the estuary of the Komo River. They are said to have named it Gabão — Portuguese for a hooded cloak or greatcoat — after the shape of the estuary, and the name Gabon derives from this. The Portuguese were followed over the next centuries by Dutch, English and French traders who dealt with the coastal peoples in ivory, ebony and other tropical woods, beeswax and, increasingly, enslaved people. Portions of southern Gabon were loosely linked to the kingdom of Loango, itself associated with the wider Kongo world to the south.
The Atlantic slave trade reached its greatest intensity on this coast between roughly the 1760s and the 1840s, driven by demand from Brazil and Cuba. Coastal Myènè polities — above all the Orungu kingdom at Cape Lopez, alongside Loango further south — operated as middlemen, channelling captives brought from the interior to European and American slavers offshore. By the late eighteenth century several hundred captives a year were being embarked at points described in the records as Gabon and Cape Lopez, and the trade reshaped coastal society and politics before its suppression in the nineteenth century.
“The Portuguese named the estuary Gabão, for a hooded cloak — and from that name came Gabon.”

Chapter 03 · 1839 – 1910
Libreville, Brazza, and French conquest
France signed treaties with Mpongwe rulers from 1839, settled freed captives at Libreville in 1849, and through Pierre Savorgnan de Brazza's Ogooué expeditions extended its rule, folding Gabon into French Equatorial Africa in 1910.
French involvement in Gabon was formalised in 1839, when the naval officer Édouard Bouët-Willaumez signed a treaty with the Mpongwe ruler Antchouwe Kowe Rapontchombo, known to the French as King Denis, granting France trading and basing rights on the estuary. American Protestant missionaries established a station at Baraka in 1842. In 1849 the French navy resettled freed Africans taken from a captured slave ship at a site on the estuary; the settlement was named Libreville — "free town" — and grew into the colonial capital and the modern capital of Gabon.
From the 1870s the Italian-born French explorer Pierre Savorgnan de Brazza (1852–1905) opened the interior. His first Ogooué mission (1875–1878) ascended the river largely by negotiation and barter rather than force; his second (1879–1882) carried French influence up the Ogooué and across to the Congo River, where he secured treaties — including with the Téké ruler Makoko — that became the basis of the French Congo. Brazza founded Franceville on the upper Ogooué in 1880 and later served as the French Congo's commissioner-general.
Through the 1880s France consolidated its hold by treaty and administration. An enlarged Gabon was joined to the French Congo in 1886, and Libreville served as the colony's administrative centre. In 1910 the French reorganised their Central African possessions into French Equatorial Africa — a federation of Gabon, the Middle Congo, Ubangi-Shari and Chad, governed from Brazzaville — within which Gabon was constituted as a separate colony. Colonial Gabon's economy rested heavily on the export of timber, especially okoumé, often extracted under harsh conditions of forced and contract labour.
“Freed from a captured slave ship, the first settlers gave their new home a name that was also a promise: Libreville, the free town.”

Chapter 04 · 1910 – 1960
Colonial Gabon and the road to independence
Within French Equatorial Africa, Gabon's forests fed a timber economy, Albert Schweitzer opened his hospital at Lambaréné in 1913, and a new African political class emerged that carried the colony to independence in 1960.
As a colony of French Equatorial Africa, Gabon was governed from Brazzaville and administered through a small French apparatus that relied on African intermediaries and, for decades, on forced and indentured labour. The economy turned on the export of tropical hardwoods — above all okoumé, prized for plywood — cut from the equatorial forest and floated down the Ogooué and lesser rivers to the coast. Population remained sparse and dispersed, and missionary churches, both Catholic and Protestant, became central institutions of colonial society.
In 1913 the Alsatian theologian, organist and physician Albert Schweitzer (1875–1965) and his wife Hélène arrived at Lambaréné, on the Ogooué, and founded a hospital near an existing mission. The Hôpital Albert Schweitzer treated thousands of patients drawn from a wide region and, sustained over half a century, made Lambaréné internationally known; Schweitzer's philosophy of "reverence for life" and his medical work were recognised with the Nobel Peace Prize in 1952.
After the Second World War, France's reforms gave the colonies representation and a measure of self-government, and a Gabonese political class came to the fore. Léon M'ba, a former colonial official and Libreville mayor, and the lawyer Jean-Hilaire Aubame led rival movements. Under the framework of the 1956 loi-cadre and the 1958 French Community, Gabon advanced to internal autonomy as the Gabonese Republic, with M'ba as head of government, setting the stage for full independence.
“At Lambaréné on the Ogooué, Schweitzer built a hospital out of a mission and a conviction he called reverence for life.”

Chapter 05 · 1960 – 2023
Independence, oil, and the Bongo era
Independent in 1960 under Léon M'ba, Gabon fell after his death to Omar Bongo, who ruled for over four decades on oil wealth and a one-party state; his son Ali Bongo followed, until a military coup in 2023 ended the family's 56-year rule.
Gabon became independent on 17 August 1960, with Léon M'ba (1902–1967) as its first leader; he was elected president in February 1961. M'ba's pro-French, increasingly authoritarian rule provoked a coup attempt in February 1964, which French troops swiftly reversed, restoring him to power and underlining the close post-independence partnership between Libreville and Paris. When M'ba died in November 1967, he was succeeded by his vice-president, Albert-Bernard Bongo.
Bongo — who converted to Islam in 1973 and took the name Omar — consolidated control, establishing a single-party state under the Gabonese Democratic Party (PDG) in 1968. His long rule, one of the longest of any African leader, was financed by Gabon's growing oil production, which gave the small, sparsely populated country one of the higher per-capita incomes in sub-Saharan Africa while wealth remained highly concentrated. Under domestic and international pressure, Bongo reintroduced multiparty politics in 1990, but the PDG retained power through contested elections. He died in June 2009, having ruled for over forty years.
Omar Bongo's son Ali Bongo Ondimba won the 2009 presidential election and was re-elected amid disputes in 2016; a stroke in 2018 left lingering questions over his fitness to govern. After a presidential election on 26 August 2023 that authorities said he had won, military officers led by General Brice Clotaire Oligui Nguema seized power in the early hours of 30 August 2023, annulling the result and detaining Ali Bongo. The coup ended the Bongo family's 56-year hold on the presidency; Oligui Nguema was installed as transitional leader, opening an uncertain new chapter in Gabon's politics.
“The coup of 30 August 2023 ended fifty-six years in which a single family held the presidency of Gabon.”
