It formed in Paris in 1985[1] from a coalition of four pre-existing groups in opposition to both opposition leader Goukouni Oueddei and President Hissène Habré, and was dominated by southern Chadians.
[1] Among its members was the future Prime Minister Jean Alingué Bawoyeu.
At the end of 1985 the group participated with Alphonse Kotiga's Codos and Acheikh ibn Oumar's CAC-CDR at peace talks with Habré at Libreville in Gabon under the patronage of Omar Bongo.
The accord also tried to fix a deadline for the adoption of a democratic constitution, and this party's goal was reasserted in a press conference on March 4, 1986, when Djogo stated that the FDT saw as the sole solution to Chad's crisis a return to democratic institutions.
But in truth the FDT was rapidly co-opted in the sole legal party, Habré's National Union for Independence and Revolution (UNIR), of which Djogo became a member of the Central Committee in 1989.
