How has war influenced art in the 20th century?

War profoundly influenced 20th-century art by serving as both a subject and a catalyst for innovation. Artists responded to the trauma of World Wars I and II, often using their work to critique violence and explore themes of loss, destruction, and the human condition. Movements such as Dada and Surrealism emerged as reactions to the absurdity of war, while later styles like Abstract Expressionism and Pop Art reflected the societal changes and existential questions raised by conflict. Overall, war has shaped artistic expression, pushing creators to confront and reinterpret the complexities of human experience.
