While the political impact of Italy's 1936 Ethiopian invasion has long been recognized, its cultural history has only recently come under scrutiny. This paper investigates one musical legacy of Mussolini's colonial project by means of a case study of Alfredo Casella's Il deserto tentato (The Attempted Desert, 1937). Performed on the first anniversary of the Empire's founding and dedicated to ‘Mussolini, fondatore dell'Impero’, the work depicts the arrival of a group of Italian airmen in Ethiopia and their welcome by the indigenous peoples. I set the text against contemporary propaganda such as speeches, visual imagery and popular song, exploring tropes central to fascist imperialist rhetoric: virility, civiltà and aeronautical prowess. The opera's integration of historical musical references into a modern musical setting not only represents the theme of endowing the Ethiopian people with a history, in this case embodied by the Italian musical past, but also exemplifies a contemporary desire to make the past present in everyday fascist life. The historiography of Casella's work, what is more, characterized by the same ‘missing debate’ as the broader discussion of Italian colonialism, raises questions about the effects of Italy's ‘memory wars’ on accounts of twentieth-century Italian music history.
