The earliest romantic poetry group in Britain appeared at the end of the 18th century, represented by Wordsworth, Coleridge and Southey. They are so named because they once lived in seclusion in the Lake District in northwest England. They are extremely disgusted with capitalist civilization and the cash transaction relationships between people, and yearn for the feudal society of the Middle Ages. Their poems may eulogize patriarchal rural life and natural scenery, or describe strange and mysterious stories and exotic scenery, which are generally themes far away from social struggles. They often deny the ugly urban civilization by remembering the "simplicity" of the medieval era. Wordsworth was the most accomplished poet of the "Lakeside School". In 1798, "Lyric Ballads" co-authored by him and Coleridge was published. When "Lyric Ballads" was republished two years later, Wordsworth wrote a preface to the collection of poems, proposing that poetry is "a natural outpouring of strong emotions" and emphasizing the use of folk language to write about pastoral life and the poet's true feelings. This later became the manifesto of British Romanticism.
