Courtly love is an academic concept used to describe a medieval European literary and social construct of idealized, often non-marital, romantic devotion that emerged in the courts of the 12th century. As a research concept, it investigates the conventions, themes, and social dynamics represented in troubadour poetry and Arthurian romance, characterized by the lover's subservience to a noble lady, the ennobling power of love, and its frequently unattainable or secretive nature. Its significance lies in its profound influence on Western literary traditions and its role as a key subject in the study of medieval culture, gender roles, and emotional history.
