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).
This passage describes how President François Tombalbaye's policies and the events of the Guéra Prefecture riots led to the formation of the Liberation Front of Chad (FLC) and its subsequent merger with the Chadian National Union (UNT) to form the National Liberation Front of Chad (FROLINAT).
