Gontchomé Sahoulba (16 October 1909[1] – 1963) was a Chadian politician who played a prominent role during the decolonization in Chad.
From 1953 the UDT started to be superseded in French and popular support by the Chadian Social Action (AST), to which Sahoulba adhered with other prominent politicians like Ahmed Koulamallah, Bechi Sow and Ahmed Kotoko.
But the picture radically changed in 1956, with the electoral reforms that greatly expanded the number of eligible voters, giving strength to the Gabriel Lisette's nationalistic Chadian Progressive Party (PPT).
Sahoulba decided with others to leave the AST before the 1957 elections for the Territorial Assembly, forming the Groupement des Indépendants et Ruraux Tchadiens (GIRT).
Gabriel Lisette formed Chad's first African government, but it didn't last long: Sahoulba and Koulamallah formed a new party, the Chadian Popular Movement (Mouvement Populaire Tchadien or MPT) which following a motion of no confidence presented February 11, 1959, was instrumental in causing the downfall of Lisette.
