Postmodern theatre emerged in the late 20th century, challenging traditional conventions and narrative structures. It embraces deconstruction, intertextuality, and metatheatre, rejecting fixed truths and exploring multiple interpretations through fragmented, non-linear narratives. Influenced by cultural upheavals and avant-garde movements, postmodern theatre reflects skepticism towards grand narratives. It incorporates elements of popular culture, irony, and parody to critique dominant ideologies, pushing boundaries in form, content, and audience engagement.
