History

Issia Department was created in 1980 as first-level subdivision via a split-off from Daloa Department. In 1997, regions were introduced as new first-level subdivisions of Ivory Coast; as a result, all departments were converted into second-level subdivisions. Issia Department was included in Haut-Sassandra 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, Issia Department remained part of the retained Haut-Sassandra Region in the new Sassandra-Marahoué District.
