Much of Gabon, which is situated astride the equator, is drained by the Ogooué River (and its tributaries, the Ngounie and the Ivindo), which flows into the Atlantic through a long and broad estuary. The rest of the coastline comprises a narrow low-lying strip, which, south of the Ogooué's mouth, includes a series of lagoons. The interior of the country is made up of mountain ranges and high-lying plateaus. To the north of the Ogooué are the Cristal Mts. and to the south is the Chaillu Massif, which includes Mt. Iboundji (5,165 ft/1,574 m), Gabon's highest point. In the northeast is the Woleu-Ntem Plateau, which reaches c.2,500 ft (760 m), and in the southeast is the hot and arid Bateke Plateau (c.2,700 ft/820 m).
The inhabitants of Gabon belong to several ethnic groups including the Fang (who make up about one quarter of the population) in the north, the Omiéné along the coast, the Bakota in the northeast, and the Eshira in the southwest. French is the country's official language, but African languages are also spoken. There are large numbers of immigrant workers from other French-speaking African nations, as well as roughly 50,000 Europeans, most of whom are French. The population is predominantly Christian in the cities, but most people in the countryside adhere to traditional beliefs.
Since the 1970s the Gabonese economy has been centered on the oil industry, which has provided it with the highest per capita income in sub-Saharan Africa and accounts for 80% of its export income. Gabon's economy is subject to fluctuating oil prices, and it must contend with diminishing reserves. Decreases in production since the mid-1990s have hurt the economy. The exploitation of forest products and the mining of manganese, which formed the backbone of the economy until oil became predominant, remain relatively important today. The country's most significant forest products are okume (a softwood used in making plywood), mahogany, and ebony. Other minerals extracted are uranium ores, gold, and iron.
The chief manufactures of Gabon's industrial sector include refined petroleum, food and beverages, timber and plywood, cement, and textiles. Despite this economic activity, the majority of Gabonese workers are engaged in subsistence farming, with cassava, plantains, taro, and sugarcane the chief crops. However, food must be imported to meet the country's needs. Cocoa, coffee, and palm products are produced for export. Few animals are raised, partly because of the prevalence of the tsetse fly.
Gabon's main exports are crude petroleum, forest products, manganese and uranium ores, and cocoa; the principal imports are foodstuffs, chemical and petroleum products, construction materials, and machinery. The leading trade partners are France, the United States, Côte d'Ivoire, and Japan. Gabon's limited transportation network was improved with the construction (1986) of the Trans-Gabon railway, which links the new deepwater port of Owendo with iron ore and manganese deposits. Gabon is a member of the Franc Zone.
The region that is now Gabon was inhabited in Paleolithic times. By the 16th cent. A.D. the Omiéné were living along the coast, and in the 18th cent. the Fang entered the region from the north. From the 16th to the 18th cent. the area was part of the decentralized Loango empire, which included most of the area between the Ogooué and Congo rivers. In the 1470s, Portuguese navigators found the Ogooué estuary, and shortly thereafter they began to trade with coastal merchants for slaves who had been acquired in the interior. The Portuguese were followed by Dutch, English, and French traders, and by the late 18th cent. the French had gained a dominant position. Despite the abolition of the slave trade (1815) by the Congress of Vienna, slaves continued to be exported from the Gabon coast until the 1880s, although French naval patrols succeeded in reducing the number exported annually.
In the mid-19th cent., several treaties were signed with African rulers of the Ogooué estuary and neighboring territories, and Christian missions were established. In 1849, Libreville was founded by the French as a settlement for freed slaves. Paul B. Du Chaillu (in the 1850s) and A. M. A. Aymes (in the 1860s) explored the lower Ogooué. In the late 1870s, Pierre Savorgnan de Brazza reached the source of the river, and in the 1880s he founded Franceville (near the present-day border with the Republic of the Congo). In 1885 the Conference of Berlin recognized French rights to the region N of the Congo River that included Gabon. In 1886 the French assigned a governor to Gabon, which from 1889 to 1904 was included in the French Congo.
From 1910 to 1957, Gabon was a part of French Equatorial Africa. The Fang and some other African peoples resisted the imposition of French rule until 1911. In 1913, Albert Schweitzer established a hospital at Lambaréné on the Ogooué. During World War II, Free French forces gained control (1940) of Gabon from the Vichy government. In 1946, Gabon became an overseas territory of France, and in 1958 the country became internally self-governing within the French Community.
The New NationOn Aug. 17, 1960, Gabon became an independent republic. Leon Mba, a Fang, was the country's first president. In Feb., 1964, Mba was ousted by a military coup led by Jean-Hilaire Aubame, but he was restored to power within a day with the help of French troops. Mba died in 1967 and was succeeded by Omar Bongo, who established (1968) the Gabonese Democratic party (PDG) as the country's sole political organization. Bongo was returned to office in the elections of 1973 and 1979.
Gabon was one of the few African countries to recognize and furnish supplies to Biafra during the Nigerian civil war (1967-70). During its first decade of independence, Gabon retained close political and economic ties with France. In the early 1970s, however, the government sought increased influence in the foreign (mainly French) companies active in Gabon, and it generally tried to loosen its ties with France. Disillusionment with Bongo's repressive policies led to the formation of a large opposition movement in the early 1980s and demands for a multiparty government.
Bongo was reelected to a fourth term in 1986. Popular discontent with the regime reached a high point in 1989 with seven days of riots in Port-Gentil, which were put down by the army. In 1990 opposition parties were legalized and multiparty legislative elections were held for the first time in 22 years. Amid charges of fraud, Bongo's party won a majority of seats. The same charges were leveled as Bongo was reelected in Gabon's first multiparty presidential election in 1993.
Despite constitutional reforms (1995) intended to reduce election fraud, the 1998 polls, in which Bongo once again was reelected, were termed unfair by observers. Bongo's party again won a majority of the legislative seats in 2001. The president was elected to a third term in 2005; the election was again criticized by the opposition, which was divided and relatively weak. The Dec., 2006, legislative elections were again solidly won by the president's party, but voter turnout was low.
