Postmodern poetry emerged in the late 20th century as a reaction against the conventions of modernist poetry. It often features fragmented structures, playful language, and a mix of different styles and genres. This form of poetry challenges traditional notions of meaning and authorship, emphasizing the role of the reader in interpreting the text. Many postmodern poets, such as John Ashbery and Langston Hughes, incorporate elements of popular culture, irony, and self-referentiality. Their work often blurs the boundaries between high and low art, reflecting the complexities of contemporary life and questioning established narratives.
