Offering a unique account of identity formation in Ireland and Central Europe, this book explores and contextualises transfers and comparisons between Ireland and the successor states of the Austro-Hungarian Empire. It reveals how Irish perceptions of borders and identities changed after the (re)birth of the small states of Austria, Hungary and Czechoslovakia and the creation of the Irish Free State. Adopting a transnational approach, the book documents the outward-looking attitude of Irish nationalists and provides original insights into the significance of personal encounters that transcended the borders of nation-states. Drawing on a wide range of official records, private papers, contemporary press accounts and journal articles, Imagining Ireland Abroad, 1904-1945 bridges the gap between historiographies of the East and West by opening up a new perspective on Irish national identity.
