Franz Kafka was a German-speaking Bohemian Jewish novelist and writer from Prague. He is widely regarded as one of the major figures of 20th-century literature. His work fuses elements of realism and the fantastic. It typically features isolated protagonists facing bizarre or surrealistic predicaments and incomprehensible socio-bureaucratic powers. It has been interpreted as exploring themes of alienation, existential anxiety, guilt, and absurdity. His best known works include the novella The Metamorphosis and novels The Trial and The Castle. The term Kafkaesque has entered English to describe absurd situations like those depicted in his writing.
