Rationing and illegal food trade in Second World War Italy have received very little scholarly attention in comparison to the scale and impact they had on people's daily life. This article contributes to filling this gap, first by providing an overview of the dynamics that already in the early years of the war determined the development of an illegal system of food trade. It then considers the experience of the black market through two wartime diaries, one published and the other unpublished, written by women of opposite political views, both living in Rome and its outskirts. The analysis of the diaries considers women's attitudes towards the black market. The article argues that the Fascist propaganda of duty to the homeland, so intensively practised through domestic literature during the 1920s and 1930s, was again exploited in wartime in the discourse around the black market and hid the political responsibilities of the government.
