Italian East Africa was a colonial administrative entity of the Kingdom of Italy in the Horn of Africa that existed from 1936 to 1941. It was proclaimed by Benito Mussolini on 1 June 1936, following the conquest and annexation of Ethiopia during the Second Italo-Ethiopian War. It encompassed Italian Somaliland, Italian Eritrea and the Ethiopian territories, all administered by a single administrative unit, the Governo Generale dell'Africa Orientale Italiana. The colony was divided into six governorates: Eritrea, Somalia, Harar, Galla-Sidamo, Amhara and Scioa.
