This book analyzes particular patterns of nationalist self-configuration and nationalist uses of memory, counter-memory, and historical amnesia in Ireland from roughly around the time of the emergence of a broad-based non-sectarian Irish nationalist platform in the late eighteenth century (the Society of United Irishmen) until Ireland's partition and the founding of the Irish Free State in 1922. In approaching Irish nationalism through the particular historical lens of "Iran," this book underscores the fact that Irish nationalism during this period (and even earlier) always utilized a historical paradigm that grounded Anglo-Irish encounters and Irish nationalism in the broader world history, a process that I term "worlding of Ireland." In effect, Irish nationalism was always politically and culturally cosmopolitan in outlook in some formulations, even in the case of many nationalists who resorted to insular and narrowly defined exclusionary ethnic and/or religious formulations of the Irish "nation." Irish nationalists, as nationalists in many other parts of the world, recurrently imagined their own history either in contrast to or as reflected in, the histories of peoples and lands elsewhere, even while claiming the historical uniqueness of the Irish experience. Present in a wide range of Irish nationalist political, cultural, and historical utterances were assertions of past and/or present affinities with other peoples and lands.

This book chiefly approaches Irish nationalist references to "Iran" as a conceptual lens for probing a broad array of developments in Irish nationalist formulations of Irish history (from ancient times to post-Norman conquests), as well as formulations of Irish identities and modes of "collective" nationalist recollection. Key thematic examples in the book range from the late eighteenth-century antiquarian debates on Irish origins to the "Iran/Erin" interchange in Irish nationalist poetry of the likes of Thomas Moore and James Clarence Mangan in the first half of the nineteenth century, the coverage of the Anglo-Iranian War of 1856–1857 in the Irish nationalist press, studies on Irish folklore by the likes of Lady Jane Wilde in the second half of the century, the emergent Aryanist discourse in some Irish nationalist circles after the mid-nineteenth century, Irish nationalist responses to the Iranian "Great Famine" of 1870–1872, references to Iran in the context of Irish Literary Revival at the turn of the twentieth century, Irish nationalist advocacy of the Iranian Constitutional Revolution of 1906–1911, and cross-territorial expressions of solidarity during and after the First World War. The only exception to the general timeline covered in the book is the section on James Joyce's Finnegans Wake (1939), which serves as a means of interrogating the post-1922 shrinking world horizon of nationalist historiography and politics in the Irish Free State.
