Romanticism was a literary and artistic movement between 1770-1870 that valued emotion, nature, imagination, and the individual. Key aspects included emphasizing feelings over reason, seeing nature as a divine work of art, using symbolism and myth, and focusing on the passions of both artists and romantic heroes who strive for the extraordinary. Romanticism criticized rigid social norms and industrialization, instead promoting intuition and a close connection between humans and the natural world.
