W. B. Yeats was an Irish poet and playwright, born on June 13, 1865, in Dublin, Ireland. He is considered one of the greatest poets of the 20th century and was a key figure in the Irish Literary Revival. Yeats's work often reflects themes of mysticism, folklore, and the complexities of love and politics. In 1923, Yeats was awarded the Nobel Prize in Literature for his outstanding contribution to poetry. His notable works include "The Lake Isle of Innisfree" and "The Second Coming." Yeats's influence extends beyond poetry, as he also played a significant role in founding the Abbey Theatre in Dublin.
