Book excerpt: This is a major new contribution to the historiography of the First World War. It examines the lively battle of ideas which helped to destroy Austria-Hungary. It also assesses, for the first time, the weapon of 'front propaganda' as used by and against the Empire on the Italian and Eastern Fronts. Based on material in eight languages, the work challenges accepted views about Britain's primacy in the field of propaganda, while casting fresh light on the creation of Yugoslavia and the viability of the Habsburg Empire in its last years.
