Galeazzo Ciano

Gian Galeazzo Ciano, 2nd Count of Cortellazzo and Buccari ( CHAH-noh, Italian: [ɡaleˈattso ˈtʃaːno]; 18 March 1903 – 11 January 1944), was an Italian diplomat and politician who served as Minister of Foreign Affairs of the Kingdom of Italy under the government of his father-in-law, Benito Mussolini, from 1936 until 1943. During this period, he was widely seen as Mussolini's most probable successor as head of government.

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.

In July 1943, Ciano was among the members of the Grand Council of Fascism that forced Mussolini's ousting and subsequent arrest. Ciano proceeded to flee to Germany but was arrested and handed over to Mussolini's new regime based in Salò, the Italian Social Republic. Mussolini ordered Ciano's death, and in January 1944, he was executed by firing squad.

Ciano wrote and left behind a diary that has been used as a source by several historians, including Winston Churchill in his six-volume work The Second World War, William Shirer in his 1960 book The Rise and Fall of the Third Reich and in the four-hour HBO documentary-drama Mussolini and I (1985).
