Italy’s 1935 Ethiopian invasion briefly united three Somali territories under one colonial power

Evidence

The Italian invasion of Ethiopia in 1935 temporarily created Italian East Africa and united three Somali territories that had been heretofore divided. For a short time, it seemed the fascist regime would be finally successful in fulfilling its dream of creating a dominant presence in East Africa. However, that illusion was dispelled by the quick British advance from its East African base in 1941. — Abdi Ismail Samatar, Africa’s First Democrats, 176
