Italian East Africa (Italian:Africa Orientale Italiana) was an Italian colony established on June 1936. It was formed through the merger of Italian Somaliland, Italian Eritrea and Italian Ethiopia.

In August 1940, during the Second World War, British Somaliland was conquered and annexed to Italian East Africa, which in 1941 was itself conquered during the East African Campaign by a British-led force of combined British, including colonial, and Ethiopian units. British Somaliland, Italian Somaliland and Eritrea then came under British administration. In 1949, Italian Somaliland was reconstituted as the Trust Territory of Somaliland, which was administered by Italy from 1950 until its independence in 1960.
