Unified Democratic Party

Unified Democratic Party, was, despite its name, not a political party but an electoral alliance of two parties, the Voltaic [Democratic Party] and the Social [Party for the Emancipation of the African Masses], ahead of the 1957 territorial assembly elections in Upper Volta. PDU won 33 out of 70 seats.
After the elections PDU formed a government together with the Voltaic Democratic Movement. PDU held seven ministries and MDV five. The unity proved short-lived. PSEMA and MDV revolted against the vice-president Ouezzine Coulibaly and formed an opposition bloc, Voltaic Solidarity. Thus PDU was no more.
