Bringing together leading international scholars of modern Ireland, its diaspora, and the British Empire, this volume discusses the Irish revolution in a truly global sense. The text situates the conflict in the wider context of the international flourishing of anti-colonial movements following World War I. Despite the differences between these movements, their proponents communicated extensively with each other, learning from and engaging with other revolutionaries in anti-imperial metropoles such as Paris, London, and New York. The contributors to this volume argue that Irish nationalists at home and abroad were intimately involved in this exchange, from mobilizing Ireland's vast diaspora in support of Irish independence to engaging directly with radical causes elsewhere. The Irish Revolution is a vital work for all those interested in Irish history, providing a new understanding of Ireland's place in the evolving postwar world.
