Romantic poetry first emerged in 1798 with the publication of Lyrical Ballads by William Wordsworth and Samuel Taylor Coleridge. It was characterized by an emphasis on imagination and emotion, individual experience over universal themes, and a love of nature. Major romantic poets included Wordsworth, Coleridge, Lord Byron, Percy Bysshe Shelley, and John Keats. They sought to incorporate ordinary language and focus on the "essential passions of the heart." The second generation including Byron, Shelley, and Keats had short but influential lives and addressed feelings of alienation.
