In 1997, regions were introduced as new first-level subdivisions of Ivory Coast; as a result, all departments were converted into second-level subdivisions. Oumé Department was initially included in Marahoué Region, but in 2000 Oumé Department was combined with Haut-Sassandra's Gagnoa Department to create Fromager Region. In 2011, districts were introduced as new first-level subdivisions of Ivory Coast. At the same time, regions were reorganised and became second-level subdivisions and all departments were converted into third-level subdivisions. At this time, Oumé Department became part of Gôh Region in Gôh-Djiboua District. Notes Departments of Gôh 1980 establishments in Ivory Coast States and territories established in 1980
