Which genre is most associated with the British/American Post-Modernistic period?

The genre most associated with the British/American Post-Modernistic period is metafiction and magic realism. This era is characterized by a blending of different styles and techniques that challenge traditional narratives and offer complex views of reality.

Metafiction explicitly draws attention to the nature of fiction itself, often blurring the boundaries between fiction and reality. It prompts readers to reflect on the act of storytelling, thus becoming self-referential. Works in this genre question the constructs of narrative and often include authorial intrusions or commentary on the storytelling process.

Magic realism introduces fantastical elements into realistic settings, allowing for a unique exploration of identity and culture. This genre can often highlight themes of disillusionment and societal issues, which resonate closely with post-modernist themes.

While historical fiction, stream-of-consciousness poetry, and romantic poetry each have their own merit and significance, they do not encapsulate the distinctive characteristics of the post-modernist period as profoundly as metafiction and magic realism do.
