Earliest inhabitants of the area were Pygmy peoples. They were largely replaced and absorbed by Bantu tribes as they migrated.
In the 15th century, the first Europeans arrived. The nation's present name originates from "Gabão", Portuguese for "cloak", which is roughly the shape of the estuary of the Komo River by Libreville. French explorer Pierre Savorgnan de Brazza led his first mission to the Gabon-Congo area in 1875. He founded the town of Franceville, and was later colonial governor. Several Bantu groups lived in the area that is now Gabon when France officially occupied it in 1885.
In 1910, Gabon became one of the four territories of French Equatorial Africa, a federation that survived until 1959. These territories became independent on August 17, 1960. The first president of Gabon, elected in 1961, was Léon M’ba, with Omar Bongo Ondimba as his vice president. French interests were decisive in selecting the future leadership in Gabon after Independence; French logging interests poured funds into the successful election campaign of M'ba, an évolué from the coastal region.
After M'ba's accession to power, the press was suppressed, political demonstrations banned, freedom of expression curtailed, other political parties gradually excluded from power and the Constitution changed along French lines to vest power in the Presidency, a post that M'ba assumed himself. However, when M'ba dissolved the National Assembly in January 1964 to institute one-party rule, an army coup sought to oust him from power and restore parliamentary democracy. The extent to which M'ba's dictatorial regime was synonymous with "French Interests" then became blatantly apparent when French paratroopers flew in within 24 hours to restore M'ba to power.
After a few days of fighting, the coup was over and the opposition imprisoned, despite widespread protests and riots. The French government was unperturbed by international condemnation of the intervention, and paratroops still remain in the Camp de Gaulle on the outskirts of Gabon's capital. When M'Ba died in 1967, Bongo replaced him as president.
In March 1968, Bongo declared Gabon a one-party state by dissolving the BDG and establishing a new party—the Parti Democratique Gabonais (PDG). He invited all Gabonese, regardless of previous political affiliation, to participate. Bongo sought to forge a single national movement in support of the government's development policies, using the PDG as a tool to submerge the regional and tribal rivalries that had divided Gabonese politics in the past. Bongo was elected President in February 1975; in April 1975, the position of vice president was abolished and replaced by the position of prime minister, who had no right to automatic succession. Bongo was re-elected President in both December 1979 and November 1986 to 7-year terms.
Economic discontent and a desire for political liberalization provoked violent demonstrations and strikes by students and workers in early 1990. In response to grievances by workers, Bongo negotiated with them on a sector-by-sector basis, making significant wage concessions. In addition, he promised to open up the PDG and to organize a national political conference in March–April 1990 to discuss Gabon's future political system. The PDG and 74 political organizations attended the conference. Participants essentially divided into two loose coalitions, the ruling PDG and its allies, and the United Front of Opposition Associations and Parties, consisting of the breakaway Morena Fundamental and the Gabonese Progress Party.
The April 1990 conference approved sweeping political reforms, including creation of a national Senate, decentralization of the budgetary process, freedom of assembly and press, and cancellation of an exit visa requirement. In an attempt to guide the political system's transformation to multiparty democracy, Bongo resigned as PDG chairman and created a transitional government headed by a new Prime Minister, Casimir Oye-Mba. The Gabonese Social Democratic Grouping (RSDG), as the resulting government was called, was smaller than the previous government and included representatives from several opposition parties in its cabinet. The RSDG drafted a provisional constitution in May 1990 that provided a basic bill of rights and an independent judiciary but retained strong executive powers for the president. After further review by a constitutional committee and the National Assembly, this document came into force in March 1991.
Opposition to the PDG continued after the April 1990 conference, however, and in September 1990, two coup d'état attempts were uncovered and aborted. Despite anti-government demonstrations after the untimely death of an opposition leader, the first multiparty National Assembly elections in almost 30 years took place in September–October 1990, with the PDG garnering a large majority.
Following President Omar Bongo's re-election in December 1993 with 51% of the vote, opposition candidates refused to validate the election results. Serious civil disturbances led to an agreement between the government and opposition factions to work toward a political settlement. These talks led to the Paris Accords in November 1994, under which several opposition figures were included in a government of national unity. This arrangement soon broke down, however, and the 1996 and 1997 legislative and municipal elections provided the background for renewed partisan politics. The PDG won a landslide victory in the legislative election, but several major cities, including Libreville, elected opposition mayors during the 1997 local election.
Facing a divided opposition, President Omar Bongo coasted to easy re-election in December 1998, with large majorities of the vote. While Bongo's major opponents rejected the outcome as fraudulent, some international observers characterized the results as representative despite many perceived irregularities, and there were none of the civil disturbances that followed the 1993 election. Peaceful though flawed legislative elections held in 2001-2002, which were boycotted by a number of smaller opposition parties and were widely criticized for their administrative weaknesses, produced a National Assembly almost completely dominated by the PDG and allied independents. In November 2005, President Omar Bongo was elected for his sixth term. He won re-election easily, but opponents claim that the balloting process was marred by irregularities. There were some instances of violence following the announcement of Omar Bongo's win, but Gabon generally remained peaceful.
National Assembly elections were held again in December 2006. Several seats contested because of voting irregularities were overturned by the Constitutional Court, but the subsequent run-off elections in early 2007 again yielded a PDG-controlled National Assembly.
On June 8, 2009, President Omar Bongo died of cardiac arrest at a Spanish hospital in Barcelona, ushering in a new era in Gabonese politics. In accordance with the amended constitution, Rose Francine Rogombe, the President of the Senate, became Interim President on June 10, 2009. The first contested elections in Gabon’s history that did not include Omar Bongo as a candidate were held on August 30, 2009 with 18 candidates for president. The lead-up to the elections saw some isolated protests, but no significant disturbances. Omar Bongo’s son, ruling party leader Ali Bongo Ondimba, was formally declared the winner after a 3-week review by the Constitutional Court; his inauguration took place on October 16, 2009.
The court's review had been prompted by claims of fraud by the many opposition candidates, with the initial announcement of election results sparking unprecedented violent protests in Port-Gentil, the country's second-largest city and a long-time bastion of opposition to PDG rule. The citizens of Port-Gentil took to the streets, and numerous shops and residences were burned, including the French Consulate and a local prison. Officially, only four deaths occurred during the riots, but opposition and local leaders claim many more. Gendarmes and the military were deployed to Port-Gentil to support the beleaguered police, and a curfew was in effect for more than 3 months.
A partial legislative by-election was held in June 2010. A newly created coalition of parties, the Union Nationale (UN), participated for the first time. The UN is composed largely of PDG defectors who left the party after Omar Bongo’s death. Of the five hotly contested seats, the PDG won three and the UN won two; both sides claimed victory.
