Dacko took part in an experimental educational program promoted by the French colonial administration. Dacko was named principal of Kouanga College in 1955 and became a supporter of independence leader Barthélémy Boganda, who was from the same Ngbaka ethnic group as Dacko. In March 1957 Dacko presented himself as a candidate for legislative elections in Ubangi-Shari for the circumscription of Ombella-M'Poko and won a seat as a member of the "Territorial Assembly of Ubangi-Shari". When the first Council of Government of Ubangi-Shari was established that same year, Boganda named Dacko Minister of Agriculture, Livestock, Water and Forests, in which position he served from 14 May 1957 until 23 August 1958. Dacko then served as Minister of the Interior and Administrative Affairs from 23 August to 8 December 1958.
