Edmund John Millington Synge was an Irish playwright, poet, writer, collector of folklore, and a key figure in the Irish Literary Revival. His best-known play The Playboy of the Western World was poorly received, due to its bleak ending, depiction of Irish peasants, and idealisation of parricide, leading to hostile audience reactions and riots in Dublin during its opening run at the Abbey Theatre, which he had co-founded with W. B. Yeats and Lady Gregory. His other major works include In the Shadow of the Glen (1903), Riders to the Sea (1904), The Well of the Saints (1905), and The Tinker's Wedding (1909).

The Celtic Revival is a variety of movements and trends in the 19th, 20th and 21st centuries that see a renewed interest in aspects of Celtic culture. Artists and writers drew on the traditions of Gaelic literature, Welsh-language literature, and Celtic art—what historians call insular art. Although the revival was complex and multifaceted, occurring across many fields and in various countries in Northwest Europe, its best known incarnation is probably the Irish Literary Revival. Irish writers including William Butler Yeats, Lady Gregory, "Æ" Russell, Edward Martyn, Alice Milligan and Edward Plunkett stimulated a new appreciation of traditional Irish literature and Irish poetry in the late 19th and early 20th century.
