The Transitional Government of National Unity (Gouvernement d'Union Nationale de Transition or GUNT) was the coalition government of armed groups that nominally ruled Chad from 1979 to 1982, during the most chaotic phase of the long-running civil war that began in 1965. The GUNT replaced the fragile alliance led by Félix Malloum and Hissène Habré, which collapsed in February 1979. GUNT was characterized by intense rivalries that led to armed confrontations and Libyan intervention in 1980. Libya intervened in support of the GUNT's President Goukouni Oueddei, against the former GUNT Defence Minister Hissène Habré. Because of international pressures and uneasy relations between Goukouni and Libyan leader Muammar al-Gaddafi, Goukouni asked the Libyans to leave Chad in November 1981; they were replaced by an Inter-African Force (IAF). The IAF showed itself unwilling to confront Habré's militia, and on June 7, 1982, the GUNT was ousted by Habré; Goukouni fled into exile. The GUNT, always under the leadership of Goukouni, became a coalition of the opposition groups aiming to overthrow Habré. Libya played once again a decisive role, providing massive support to Goukouni, and reducing the GUNT to the status of a Libyan proxy. A French intervention blocked GUNT from overthrowing Habré in 1983 and limited Libyan-GUNT control to Northern Chad. Internal dissensions and problems with Libyan patronage, including the arrest of Goukouni by the Libyans, caused the disintegration of the GUNT in 1986. Civil war and mediation attempts From 1979 to 1982, Chad experienced unprecedented change and spiraling violence. Southerners finally lost control of what remained of the Chadian government, while civil conflicts became significantly more internationalized. In early 1979, the fragile Malloum-Habré alliance collapsed after months of aggressive actions by Habré, including demands that more northerners be appointed to high government offices and that Arabic be used in place of French in broadcasting. Appealing for support among the large communities of Muslims and Arabs in N'Djamena, Habré unleashed his Armed Forces of the North (FAN) on February 12. With the French garrison remaining uninvolved, FAN sent Félix Malloum into retirement (under French protection) and drove the remnants of the Chadian Armed Forces (FAT, the regular army) toward the south. On February 22, Goukouni Oueddei and the People's Armed Forces (FAP) entered the capital. By this time, most of the city's Sara population had fled to the south, where attacks against Muslims and nonsoutherners erupted, particularly in Sarh, Moundou, and throughout
