Because of the authoritarian and anti-Muslim policies of the President François Tombalbaye, he lived in exile in Sudan when the explosion of bloody riots in the Guéra Prefecture in 1965 opened him new chances. For this reason, he formed in his country of exile on September 7, 1965, the Liberation Front of Chad, the first insurgent group formed against Tombalbaye. A small group, at the Congress of Nyala Musa and his FLT united in 1966 with the Chadian National Union (UNT) of Ibrahim Abatcha to form the powerful National Liberation Front of Chad (FROLINAT).
The events described are connected by the actions of François Tombalbaye and his political influence. His exile in Sudan led to a new opportunity for him to start an insurgent group against his own government, which eventually united with other groups to form a powerful force.
