province of Italian East Africa (Africa Orientale Italiana), along with Ethiopia and Italian Somaliland. By 1941, Eritrea had about 760,000 inhabitants, including 70,000 Italians. Through the 1941 Battle of Keren, the British expelled the Italians and took over the administration of the country. The British continued to administer the territory under a UN Mandate until 1951, when Eritrea was federated with Ethiopia per UN Resolution 390A(V) under the prompting of the United States adopted in December 1950.
