William Faulkner's narrative style was significantly influenced by his Southern background, particularly his upbringing in Mississippi. The rich cultural heritage and complex social dynamics of the South are reflected in his use of stream of consciousness and intricate character development. Faulkner's experiences with racism and the effects of historical trauma in the region often surface in his works. His engagement with the American South's history and its stark contrasts influenced the multiple perspectives and fragmented timelines in novels like "The Sound and the Fury." This deep connection to his roots helped shape a distinctive literary voice.
