Italian East Africa (Italian: Africa Orientale Italiana, A.O.I.) was a territory of the Italian empire under Fascist Italy, existing from 1936 to 1941 in the Horn of Africa. It was established following the Second Italo-Ethiopian War, which led to the military occupation of the Ethiopian Empire (Abyssinia), and encompassed Italian Somaliland, Eritrea and the Ethiopian territories (although Italy did not have stable control over the whole of Ethiopia), all governed by a single administrative unit, the Governo Generale dell'Africa Orientale Italiana. Its establishment contributed significantly to the outbreak of World War II by exposing the weaknesses of the League of Nations.
Italian East Africa was divided into six governorates. Eritrea and Somalia, Italian possessions since the 1880s, were enlarged with captured Ethiopian territory and became the Eritrea and Somalia Governorates. The remainder of the occupied Ethiopian territories comprised the Harar, Galla-Sidamo, Amhara, and Scioa Governorates. At its largest extent, Italian East Africa occupied territories in British Somaliland, British Kenya, and Anglo-Egyptian Sudan. By 1939, it was settled by about 165,270 Italian colonists.
