Realism and Naturalism emerged in the late 19th century, aiming to depict reality without idealization. These movements focused on ordinary people, everyday situations, and the impact of social, economic, and political conditions on individuals' lives. Authors like Flaubert, Zola, and Dreiser explored themes of survival, social inequality, and determinism. They used detailed descriptions, vernacular language, and objective narration to create authentic portrayals of life, often critiquing societal issues and challenging traditional beliefs.
