At the end of the 19th century and throughout the 20th century, Irish literature saw an unprecedented sequence of globally successful works, especially those by Oscar Wilde, Bram Stoker, James Joyce, W. B. Yeats, Samuel Beckett, Elizabeth Bowen, C. S. Lewis, Kate O'Brien and George Bernard Shaw, most of whom left Ireland to make a life in other European countries such as England, Spain, France and Switzerland. Meantime, the descendants of Scottish settlers in Ulster formed the Ulster-Scots writing tradition, having an especially strong tradition of rhyming poetry.
