World War I had a profound influence on Virginia Woolf's works, shaping her modernist approach and themes of existentialism. The chaos and violence of the war led to her questioning of traditional narrative structures and a focus on subjective experience. This period prompted Woolf to explore the inner thoughts and emotional lives of her characters, often highlighting the impact of trauma. Her essays and novels reflected a conscious breaking away from Victorian norms, emphasizing the importance of individual perception. Many of her works, such as "Mrs. Dalloway," confront the fragility of life and the psychological consequences of conflict.
