The Romantic Age in English literature began in 1798 with the publication of Lyrical Ballads by Wordsworth and Coleridge. This work introduced a new form of poetry that focused on everyday life and common language, in opposition to the formal style of the Classical school. Wordsworth's Preface outlined his theory that poetry should reflect spontaneous emotions and use ordinary language. The Romantic poets, including Wordsworth, Coleridge, Byron, Shelley and Keats, embraced themes of nature, imagination, and individual liberty and helped establish poetry as the dominant genre of this period.
