The document discusses several major art movements between 1750-1850 including Romanticism, Realism, Impressionism, and Post-Impressionism. Romanticism emphasized emotion and nature, rejecting Enlightenment ideals of reason. Realism sought to depict everyday life truthfully. Impressionism focused on capturing fleeting optical impressions and effects of light through short brushstrokes and pure color. Post-Impressionism developed styles for expressing deeper emotions rather than just visual impressions. Key artists mentioned include Delacroix, Constable, Millet, Monet, Van Gogh, and others.
