The Diplomat Who Betrayed His Father-in-Law and Paid the Ultimate Price

In short: Galeazzo Ciano, Mussolini’s son-in-law and heir apparent, lived a life of extreme privilege before his disillusionment with the Axis war effort led him to vote for the Duce's ousting. His subsequent execution by firing squad remains one of the most dramatic betrayals of the Second World War.

Born into wealth and influence, Galeazzo Ciano rose rapidly through the ranks of the Fascist regime, bolstered by his marriage to Edda Mussolini in 1930. By 1936, he was appointed Minister of Foreign Affairs, a position he used to document the inner workings of the Italian government. His diaries, kept from 1937 until 1943, provide an intimate, often critical look at his interactions with Hitler, Ribbentrop, and his own father-in-law. These records later became essential historical documents, cited by figures like Winston Churchill and used as evidence during the Nuremberg Trials.

As the war turned against Italy, Ciano’s initial enthusiasm faded. He recognized the military’s lack of preparation and grew increasingly disenchanted with the alliance with Nazi Germany. His vanity, however, often clouded his judgment, as he struggled with personal slights and the realization that his political standing relied entirely on his familial connection to the Duce. By 1943, he was actively pushing for Italy to exit the conflict, a stance that culminated in his pivotal vote against Mussolini during the Grand Council of Fascism meeting on 24 July 1943.

Following Mussolini’s temporary fall, Ciano’s attempt to escape to Germany backfired. He was handed over to the Italian Social Republic, a puppet regime established by Mussolini in Salò. Despite his wife Edda’s desperate attempts to barter his diaries for his life, Ciano was tried for treason. On 11 January 1944, he was executed by firing squad alongside four other dissenters. In a final act of humiliation, the condemned men were tied to chairs before being shot. His legacy persists not only through his diaries but also in a Serbian proverb, 'Living like Count Ciano,' which captures the flamboyant, high-profile lifestyle he maintained until his final days.
