The PDD was established in 1963 by Sourou-Migan Apithy and Justin Ahomadégbé-Tomêtin following the overthrow of President Hubert Maga in a coup,[1] and replaced the Dahomeyan Unity Party as the country's sole legal party.[2] The party largely represented the interests of the Aja, Fon, Nago and Yoruba people of the south and central parts of the country.[1]
