Romanticism was a literary movement in Europe late 18th century. It was a revoluntionary movement that radically changed how artists understood their works, placing emphasis on nature, imagination, emotions (fear, horror, terror). There was a rise of the liberal movement and radical ideas. The people's struggle for equality and freedom. There were also events and ideologies of the French Revolution that were a factor because many Romantics were cultural revolutionaries and sympathetic to the cause. Romanticism promoted imagination and creativity for everyone. Mary Shelley used very descriptive language in her novel Frankenstein. She described beautiful, mysterious landscapes and scenery. Victor Frankestein and the creature were consumed with emotion and in constant pursuit of happiness.
