In northern Europe, the Early Romantic visionary optimism and belief that the world was in the process of great change and improvement had largely vanished, and some art became more conventionally political and polemical as its creators engaged polemically with the world as it was. Elsewhere, including in very different ways the United States and Russia, feelings that great change was underway or just about to come were still possible. Displays of intense emotion in art remained prominent, as did the exotic and historical settings pioneered by the Romantics, but experimentation with form and technique was generally reduced, often replaced with meticulous technique, as in the poems of Tennyson or many paintings. If not realist, late 19th-century art was often extremely detailed, and pride was taken in adding authentic details in a way that earlier Romantics did not trouble with. Many Romantic ideas about the nature and purpose of art, above all the pre-eminent importance of originality, remained important for later generations, and often underlie modern views, despite opposition from theorists.
