Libya invaded Chad in July 1980, occupying and annexing the [[Aozou Strip]]. The United States and France responded by aiding Chad in an attempt to contain Libya's regional ambitions under Libyan leader [[Muammar al-Gaddafi]].<ref name="Meredith"/>{{Rp|354}}

In 1980, the unity government signed a treaty of friendship and cooperation with Libya. The treaty allowed the Chadian government to call on Libya for assistance if Chad's independence or internal security was threatened.<ref name="Chad-CS"/>{{Rp|191}} The [[Libyan army]] was soon assisting the government forces, under Goukouni, and ousted FAN from much of northern Chad, including N'Djamena on 15 December.<ref name="Chad-CS"/>{{Rp|191}} Libyan troops withdrew in November 1981. Without their support, Goukouni's government troops were weakened and Habré capitalized on this and his FAN militia entered N'Djamena on 7 June 1982.<ref name="Chad-CS"/>{{Rp|191}}<ref name="Meredith"/>{{Rp|354–355}} In 1983, Libyan troops returned to Chad and remained in the country, supporting Goukouni's militia, until 1988.<ref name="Chad-CS"/>{{Rp|193–198}}<ref name="Meredith"/>{{Rp|354–356}}

Despite this victory, Habré's government was weak, and strongly opposed by members of the [[Zaghawa people|Zaghawa]] ethnic group. A rebel offensive in November 1990, which was led by [[Idriss Déby]], a Zaghawa former army commander who had participated in a plot against Habré in 1989 and subsequently fled to Sudan, defeated Habré's forces. The French chose not to assist Habré on this occasion, allowing him to be ousted; it is possible that they actively aided Déby. Explanation and speculation regarding the reasons for France's abandonment of Habré include the adoption of a policy of non-interference in intra-Chadian conflicts, dissatisfaction with Habré's unwillingness to move towards multiparty democracy, and favoritism by Habré towards U.S. rather than French companies with regard to oil development. Habré fled to [[Cameroon]], and the rebels entered N'Djamena on 2 December 1990; Habré subsequently went into exile in Senegal.<ref>Bernard Lanne, "Chad: Regime Change, Increased Insecurity, and Blockage of Further Reforms", ''Political Reform in Francophone Africa'' (1997), ed.
