Postmodern literature emerged after World War II as a reaction to the new global state and a rejection of realism and modernism. It is characterized by a view of reality as chaotic and meaningless, as well as experimentation with form including fragmented and nonlinear narratives, intertextuality, and deconstruction. Postmodern works often explore themes of memory, loss, death, paranoia, and the meaninglessness of human existence through alienated characters lacking communication in an anxious world of illusions.
