As the war was going badly in early 1943, Mussolini took the dramatic step of replacing most of his government ministers. Of the men sacked, none drew more attention than Galeazzo Ciano, Mussolini's son-in-law, who had served as minister of foreign affairs since 1936. The announcement that Ciano would immediately be appointed as Italy's ambassador to the Holy See sparked much speculation in the diplomatic community, where it was viewed as a possible move by Mussolini to employ the Vatican to broker an Italian exit from the war. Others saw the appointment as a desperate move by Ciano himself to find a way out of the war. The recently opened Vatican archives for these years, along with archival evidence from Germany, Britain, the U.S., France, and Italy, offer new insight both into Ciano's attempts to ingratiate himself with Pope Pius XII and to how he in fact operated in his role as Italian ambassador to the Holy See in the months preceding the collapse of the Fascist regime.
