Founded in February 1946 by Gabriel Lisette, a black colonial administrator born in Panama, it at first attracted mainly the country's non-Muslim intellectuals; politically it was much more radical and nationalistic than its main rival, the Muslim-dominated Chadian Democratic Union (UDT). Originally much weaker than the UDT, with the 1956 electoral reforms that expanded the pool of eligible voters, the power started to pass to the Christian and Animist south where the PPT had most of its support. As a result the PPT triumphed in the 1957 elections for the Territorial Assembly, obtaining 32 seats out of 65, 47 with its allies. Gabriel Lisette, first President of the Provisional Government, stepped down in March 1959 so that a Chadian be head of the government and the party, and the choice fell on François Tombalbaye, who had just been made secretary-general of the PPT. The latter leaded the party in the the May 1959 elections, yet another lanslide for the PPT that took 57 seats out of 85. In 1960, a few weeks before independence and the assumption of the presidency, Tombalbaye exiled Lisette, so eliminating a dangerous rival; from that moment nobody dared contest him in the party, that was declared the country's sole legal party in 1962. Tombalbaye renamed his party in 1973, calling it National Movement for the Cultural and Social Revolution, that survived only two years, for in 1975 a coup overthrowed Tombalbaye and abolished his party.
