Franz Kafka was a German-language writer of novels and short stories who is widely regarded as one of the major figures of 20th-century literature. His work, which fuses elements of realism and the fantastic, typically features isolated protagonists faced by bizarre or surrealistic predicaments and incomprehensible social-bureaucratic powers, and has been interpreted as exploring themes of alienation, existential anxiety, guilt, and absurdity. His best known works include "Die Verwandlung" ("The Metamorphosis"), Der Process (The Trial), and Das Schloss (The Castle). The term Kafkaesque has entered the English language to describe situations like those in his writing.
