This thesis is about the political verse of W.B.Yeats who is one of the best known Irish poets. His work, his political work in particular, reflects on the history of his native country Ireland to a significant extent. When touching many ideologies, Yeats mostly cherished the ideas that were prominent in the form of nationalism called 'Romantic Nationalism'. These ideas of 'Romantic Nationalism' are reflected in "September 1913" and "Easter, 1916", two of Yeats's best known political poems. "Easter, 1916" comments on the effects of the Easter Rising of that year. The four poems on 'his hero' Charles Stewart Parnell pay particular respect to this person, who, for Yeats embodied the perfect Protestant. Yeats's personal experience of two wars in his country, and the terror caused by the 'Black and Tans' in Ireland are reflected on in "Meditations in Time of Civil War". The alienation of his 'class', the Anglo-Irish Protestants from the mainly Church dominated country can be traced in "Church and State" while "The Second Coming" shows his dislike of socialism and modernism and favours the ideas of a ruling 'elite'. Yeats also came into contact with the fascist movement of the 'Blueshirts' for which he wrote three songs. The people who had great influence on Yeats were Lady Gregory, Maud Gonne and John O'Leary. Having been a Senator of the Irish Free State from 1923 until 1928, a poet who was awarded the Nobel Prize for Literature in 1923 and the director of the famous Abbey Theatre make him a fine representative of his time and his country and show his interest in the culture of Ireland and its politics.
