The first British cultural institute on foreign soil was founded in Florence in 1917. However, it was the creation of the British Council in London in 1935 that marked the beginning of the strengthening of the British cultural presence abroad. The aim of this drive was to promote knowledge of British culture and civic and political life overseas, to defend national prestige and, given the escalating expansionist policies of Nazi Germany and Fascist Italy, to encourage the preservation of dialogue between the major European powers, underpinned by democratic principles. Bridging a gap in research into the relationship between Italy and Great Britain in the interwar period, this article reconstructs the case study of British cultural diplomacy in Florence between 1922 and Mussolini’s declaration of war, analysing how British culture was used in politics and propaganda and investigating the relationship of the management of both the British Institute of Florence and the British Council with Fascism. In doing so, it offers original insight into British history and the country’s cultural institutions in Fascist Italy, and into the wider field of Anglo-Italian political and cultural relations during the period of dictatorship in Italy.
