Gaddafi attempted alliances with a number of antigovernment rebel leaders in Chad during the 1970s, including Goukouni, Siddick, Acyl Ahmat (a Chadian of Arab descent), and Kamougué, a southerner. Goukouni and Acyl were most sympathetic to Gaddafi's regional ambitions, but these two men clashed in 1979, leading Acyl to form the CDR. After Acyl's death in 1982, Libyan support swung strongly to Goukouni's GUNT. Libya intervened militarily in Chad in 1978 and 1979, starting the Chadian–Libyan conflict.
