During World War II , Britain regained control of British Somaliland and conquered Italian Somaliland , administering both militarily as protectorates . In November 1945 , during the Potsdam Conference , the United Nations granted Italy trusteeship of Italian Somaliland , but only under close supervision and on the condition — first proposed by the Somali Youth League ( SYL ) and other nascent Somali political organizations , such as Hizbia Digil Mirifle Somali ( HDMS ) and the Somali National League ( SNL ) — that Somalia achieve independence within ten years . British Somaliland remained a protectorate of Britain until 1960
