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
