This book discusses how and why American modernist writers turned to Ireland at various stages during their careers. By placing events such as the Celtic Revival and the Easter Rising at the centre of the discussion, it shows how Irishness became a cultural determinant in the work of American modernists. It is the first study to extend the analysis of Irish influence on American literature beyond racial, ethnic or national frameworks. Through close readings and archival research, American literature and Irish culture, 1910–55 provides a balanced and structured approach to the study of the complexities of American modernist writers’ responses to Ireland. Offering new readings of familiar literary figures – including Fitzgerald, Moore, O’Neill, Steinbeck and Stevens – it makes for essential reading for students and academics working on twentieth-century American and Irish literature and culture, and transatlantic studies. -- .
