William Butler Yeats was one of the greatest English-language poets of the 20th century and received the Nobel Prize for Literature in 1923.

He is an Irish poet of the best symbolist in the modernist poetry. He was born in Sandymount in County Dublin, Ireland. When we say William Butler Yeats, we mention mysticism, occultism and Symbolism.

One of his poems is The Second Coming. He was concerned about something historical or about a certain belief that he had about history. This poet has his own theorization or his own concept about history that in a number of years, civilizations come to an end.

He wants to say something about the modern civilization and the world in general, not the British society or the European society or whatever; it is not a certain country. He was concerned about the world and his view was a big one.

He won the prize for:
- The Countess Cathleen
- The Wanderings of Oisin and Other Poems
- The Tower 
- Words for Music Perhaps and Other Poems

The Main Themes in his writings:
- Relationship between Art and Politics:
- The Impact of Fate and the Divine on History

One of his important poems is Sailing to Byzantium; it is a long poem which is related to this theme of divine power.

Yeats passed away on January 28, 1939, in Roquebrune-Cap-Martin, France. The publication of Last Poems and Two Plays shortly after his death further cemented his legacy as a leading poet and playwright.
