He edited the newspaper Le Messager du Dahomey with Louis Hunkanrin during World War I while also working at the Musee de l'Homme in Paris.
[4] Hazoumé wrote Le Pacte de sang au Dahomey in 1937 and the historical novel Doguicimi the following year, winning recognition and awards as both an ethnologist and novelist.
[1] In the years following World War II, Hazoumé got involved in local politics, becoming secretary of the Cotonou electoral committee.
He was the cofounder of the Dahomeyan Progressive Union (UPD), the first political party in present-day Benin, and played an important early role.
Hazoumé ran for president in the disputed elections of May 1968, but received a mere 11,091 votes, or 3.9 percent, which is attributable to strong regionalism.
