The purpose of this thesis is first to study the part that war plays in the works of the Italian historian and philosopher, Benedetto Croce (1866-1952), when he studies History -in particular that of the 19th century- as well as when he reacts to the events of which he is a contemporary: wars in Ethiopia in 1896 and 1935, in Libya in 1911- 1912 and “pacification” in the nineteen twenties and thirties, First World War, Spanish War, Second World War. Is war sometimes legitimate? Is it necessary to the construction and strengthening of the Italian State? Or on the contrary is it to be avoided at all costs? These are complex questions, for war is not the prerogative of fascism but has already been one of the important characteristics of the liberal regime that preceded fascism in Italy. This research is also focused on the thought and action of Benedetto Croce concerning peace maintaining and then restoring, in particular after both world wars, and his commitment to Europe. The study is based upon the interplay of Benedetto Croce’s works and the documents found in the State Archives in Rome, like the files of the fascist political police who watched Croce during decades because of his anti-fascist commitment.
