The reasons for the clash between Gaddafi and Goukouni were both ethnic and political. The FROLINAT was divided between Arabs, like Acyl, and Toubous, like Goukouni and Habré. These ethnic divisions also reflected a different attitude towards Gaddafi and his "Green Book". In particular, Goukouni and his men had shown themselves reluctant to follow Gaddafi's solicitations to make "The Green Book" the official policy of the FROLINAT, and had first tried to take time, postponing the question until the complete reunification of the movement. When the unification was accomplished, and Gaddafi pressed again for the adoption of "The Green Book", the dissensions in the Revolution's Council became manifest, with many proclaiming their loyalty to the movement's original platform approved in 1966 when Ibrahim Abatcha was made first secretary-general, while others, including Acyl, fully embraced the Colonel's ideas.
