When Harley Granville Barker was invited to stage a theatre season in New York following the outbreak of the First World War, senior figures within British politics seized on it as an opportunity to promote the British war effort in the United States. It was, however, Barker's impromptu decision to extend his stay and tour Euripides’ The Trojan Women to major colleges on the East Coast that saw him come close to realizing this goal. Through an examination of the production, the discourse that surrounded it, and the changing diplomatic relations between Britain and the USA, Philippa Burt explores in this article the extent to which Barker used Euripides as a propaganda tool through which to engage and educate the largely isolationist North American public. At the same time, she argues that Barker challenged the propaganda machine by refusing to perpetuate the dominant nationalistic and xenophobic narratives and, instead, intended a condemnation of all war. Philippa Burt is a lecturer in the Department of Theatre and Performance at Goldsmiths, University of London. Her previous publications include numerous articles and a chapter on Barker's work with choruses in the forthcoming The Great European Stage Directors, Vol. 4: Reinhardt, Jessner, Barker (Bloomsbury Methuen).
