"monsieur maurice" incarnated the voltaic state at the time of independence. as a member of the colonial administration, maurice yaméogo began his career in 1946 in the dense political landscape of upper volta thanks to his oratory skills. in may 1957, as part of the formation of the first volta government established by the framework law defferre, he joined the coalition government formed by ouezzin coulibaly, as minister of agriculture under the label of the movement voltaic democratic (mdv) . in january 1958, threatened by a motion of censure, ouezzin coulibaly debauched in favor of the voltaic democratic union-african democratic rally (udv-rda) maurice yaméogo and his allies at the assembly against the insurance of a promotion in the government. maurice yaméogo thus raises no. 2 of the government with the portfolio of the interior, a key position that allows him when in september 1958 ouezzin coulibaly dies, to act as interim head of government.
