After the World War II (1955) the perception of people and literary artists changed in every genre, whether poetry, adventure, fantasy, fiction, novels, etc.
Literature in the post-war period was influenced by philosophical concerns; from poetry, visual arts to existentialism and social aspects. As the intermediate postwar period separated Modernism from Postmodernism the literature got inspiring tales of bravery, self –belief and optimism to face difficult situation.
