The Gilded Age Literary Movement refers to a period of American literature from the 1870s to the early 1900s that critiques the societal issues arising during the rapid industrialization and economic growth of the United States. This movement is characterized by realism and naturalism, emphasizing social problems, class struggles, and the moral dilemmas faced by individuals in a changing society. The literature produced during this time reflects both the extravagance and the corruption of the era, which is aptly described by Mark Twain's coining of the term 'Gilded Age'.
