English Romanticism emerged during the late eighteenth century as a reaction against the rationalism, artificiality, and strict literary conventions of the Neoclassical Age. William Wordsworth and Samuel Taylor Coleridge played a decisive role in establishing this literary movement through the publication of Lyrical Ballads (1798), a work that transformed English poetry by emphasizing ordinary life, nature, imagination, emotion, and individual experience. While Lyrical Ballads marked the beginning of Romanticism, both poets continued to shape English literature through their later works and literary theories. Wordsworth's emphasis on nature, memory, and the common man, together with Coleridge's exploration of imagination, the supernatural, and philosophical criticism, laid the intellectual and artistic foundations of Romantic literature. Their influence extended beyond their own generation, inspiring poets such as Percy Bysshe Shelley, John Keats, Lord Byron, Alfred Tennyson, Robert Browning, Matthew Arnold, Thomas Hardy, W. B. Yeats, and even modern writers. This article examines their contributions, major works, literary characteristics, and enduring influence on English literature.
