In its second invasion of Ethiopia in 1935–36, Italy was successful and it merged its new conquest with its older east African colonies to create Italian East Africa. In 1939, Italy invaded Albania and incorporated it into the Fascist state. During the Second World War (1939–1945), Italy occupied British Somaliland, parts of south-eastern France, western Egypt and most of Greece, but then lost those conquests and its African colonies, including Ethiopia, to the invading allied forces by 1943. It was forced in the peace treaty of 1947 to relinquish sovereignty over all its colonies. It was granted a trust to administer former Italian Somaliland under United Nations supervision in 1950. When Somalia became independent in 1960, Italy's eight-decade experiment with colonialism had ended.
