This essay analyses Salvemini's major works on Fascism, namely The Fascist Dictatorship in Italy (1927), Mussolini Diplomate (1932) and Under the Axe of Fascism (1936). The focus of this analysis is twofold: to explore both Salvemini's methodology and the events leading to the publication of these works. In The Fascist Dictatorship in Italy, Salvemini examines the origins and the rise of Mussolini's movement, highlighting the complicity of the monarchy, the army, and industrial magnates. In Mussolini Diplomate, he analyses Fascist foreign policy from 1922 to 1932, in which Salvemini is unable to identify a consistent strategy, but only a propagandistic approach aiming to foster diplomatic relations. In Under the Axe of Fascism, Salvemini dissects Fascist economics, debunking the idea that the corporate state was an original and equitable compromise in the conflict between capital and labour, as was being portrayed abroad. An analysis of these three volumes brings into focus some noteworthy aspects of Salvemini's so-called ‘historiographical workshop’, which have hitherto been overlooked by historians (such as his adept use of sources and his endeavour to combine social sciences and economics), as well as underscoring his ability to forge cultural and intellectual networks, an essential element for undertaking such a complex task.
