The East African Campaign was defined by a number of World War Two battles fought in the Horn of Africa. British forces led an Allied advance into Italian-occupied territory between June 1940 and November 1941. Italian troops retreated through Somaliland, Eritrea and Ethiopia before eventually surrendering after the Battle of Gondar.

Eritrea remained under British military administration for the remainder of the war.
