Romanticism emerged as a reaction against Neoclassicism, emphasizing individual expression and emotion. Romantic artists found inspiration in nature, the Middle Ages, and dreams/nightmares. They explored political and social themes. Major works include Géricault's Raft of the Medusa, Goya's Third of May 1808, and Delacroix's Liberty Leading the People. Architecture revived Gothic styles. Turner and Friedrich captured the sublime in nature. Photography was invented during this period.
