Houphouët-Boigny first came to political prominence in 1944 as founder of the "Syndicat Agricole Africain", an organization that won improved conditions for African farmers and formed a nucleus for the PDCI. After World War II, he was elected by a narrow margin to the first Constituent Assembly. Representing Ivory Coast in the French National Assembly from 1946 to 1959, he devoted much of his effort to inter-territorial political organization and further amelioration of labor conditions. After his thirteen-year service in the French National Assembly, including almost three years as a minister in the French Government, he became Ivory Coast's first prime minister in April 1959, and the following year was elected its first president.
