Decadence is an academic concept used across disciplines such as history, literature, art history, and sociology to analyze periods or cultural movements characterized by perceived decline, decay, or a focus on artificiality, excess, and aestheticism often associated with the late stages of a civilization or era. It investigates societal shifts, artistic styles, and moral frameworks that diverge from earlier norms, focusing on themes of enervation, sophistication, transgression, and a sense of historical decline. Its significance lies in providing a critical lens for understanding transitional periods, aesthetic sensibilities, and anxieties about cultural change and the loss of traditional vitality.
