He was the son of Admiral Costanzo Ciano, a founding member of the National Fascist Party; father and son both took part in Mussolini's March on Rome in 1922. Ciano saw action in the Italo-Ethiopian War (1935–36) and was appointed Foreign Minister on his return. Following a series of Axis defeats in the Second World War, Ciano began pushing for Italy's exit, and he was dismissed from his post as a result. He then served as ambassador to the Vatican.
