The book was published by
Mondadori in 1933, one year after the success of
Oberdan, the reduced version of Salata's
Guglielmo Oberdan secondo gli atti segreti del processo: carteggi diplomatici e altri documenti inediti, originally published by
Zanichelli in 1924. is an analysis and history of the
Four Power Pact, a non-belligerence
treaty that was initialed in June 1933 in the
Palazzo Venezia in
Rome by France, the United Kingdom, Germany, and Italy. In the book Salata provides a genesis and background of the pact, ending with Mussolini's speech, followed by all the documents and texts (including the superseded drafts of the pact). He remarks on the quality of the speech of Mussolini, according to him the best ever given by an Italian head of state, as well as the greatest interpretation of the feeling of other populations and of the universality ever made by a head of state. Notwithstanding the perhaps excessive celebration of Mussolini, the work is considered fundamental, and an important exegesis. ==References==
