Essay from the year 2021 in the subject English Language and Literature Studies - Literature, grade: Master, , course: Master, language: English, abstract: Post-colonial theory is a typical study in literature. It tries to depict the entire world and its relations. Many philosophers are associated with this issue. Looking for Bhabha's extension in this study, he is fixed with several issues, depicting them as a means of post-colonial reading. This paper is to explore Bhabha's selected concepts: nationalism, hybridity and ambivalence. These concepts will apply to W.B.Yeats' September 1913, Nineteen Hundred and Nineteen and Easter 1916. Yeats is a good choice to be associated with post-colonial study. He tries to focus on the traditions and living of Ireland. He props the Irish independent. Moreover, he has extended with political and social issues. His views are colonial and sympathetic conducts. For September 1913: it depicts the destruction and death of Ireland's' ideals in terms of national identity. It also reflects that Irish people pay attention to themselves only, not to their land. People miss their national identity. They are not able to retrieve the beliefs and values of their country. In "e;Easter 1916"e;: people are rebellious against the British tyranny. They want to release the freedom and independence of Ireland. Once again, the poet is ambivalent towards the national identity of Ireland. In Nineteen Hundred and Nineteen: Yeats conflicts with two sides. He is in between 'colonizer and colonized'. He is a hybrid and ambivalent. Uncertainly, he does not know which side he belongs to. Finally, the three concepts play an essential role in Irish society. People are ambivalent and hybrid, and then the others are seeking about the national identity of Ireland.
