The History of Algeria from 1962 to 1999 includes the period starting with preparations for independence and the aftermath of the independence war with France in the 1960s to the Civil War and the 1999 presidential election.
In preparation for independence, the CNRA (Conseil National de la Révolution Algérienne) had met in Tripoli in May 1962 to work out a plan for the FLN's (Front de Libération Nationale) transition from a liberation movement to a political party. The Tripoli Program called for land reform, the large-scale nationalization of industry and services, and a strong commitment to nonalignment and anti-colonialism in foreign relations. The platform also envisioned the FLN as a mass organization broad enough to encompass all nationalist groups. Adoption of the Tripoli Program notwithstanding, deep personal and ideological divisions surfaced within the FLN as the war drew to a close and the date for independence approached. Competition and confrontation among various factions not only deprived the FLN of a leadership that spoke with a single voice, but also almost resulted in full-scale civil war. According to historian John Ruedy, these factions, or "clans" did not embody "family or regional loyalties, as in the Arab East, because the generations-long detribalization of Algeria had been too thorough. Rather, they represented relationships based on school, wartime or other networking."
The Armée de Libération Nationale (ALN) commanders and the GPRA (Gouvernement Provisionel de la République Algérienne) struggled for power, including an unsuccessful attempt to dismiss Colonel Houari Boumédiènne, chief of staff of the ALN in Morocco. Boumédiènne formed an alliance with Ahmed Ben Bella, who together with Mohamed Khider and Rabah Bitat, announced the formation of the Political Bureau (Bureau Politique) as a rival government to the GPRA, which had installed itself in Algiers as the "Provisional Executive". Boumédiènne's forces entered Algiers in September, where he was joined by Ben Bella, who quickly consolidated his power. Ben Bella purged his political opponents from the single slate of candidates for the forthcoming Algerian National Assembly elections. However, underlying opposition to the Political Bureau and to the absence of alternative candidates was manifested in an 18 percent abstention rate nationwide that rose to 36 percent of the electorate in Algiers.
