Romanticism was an artistic and intellectual movement of the 19th century characterized by five "I"s: imagination, intuition, idealism, inspiration, and individuality. It emphasized emotion, subjectivity, and the individual over reason. Romantic artists and writers celebrated nature, medieval chivalry, and the individual spirit. The movement began as a reaction against order and restraint of the prior Neoclassical period, influencing literature, visual arts, and music through more emotional and imaginative expression.
