Percy Bysshe ShelleyPercy Bysshe Shelley ( ; 4 August 17928 July 1822) was one of the major English Romantic poets, widely regarded as one of the greatest lyric and philosophical poets in the English language. A radical in his poetry as well as in his political and social views, Shelley did not see fame during his lifetime, but recognition of his achievements in poetry grew steadily following his death. Shelley became a key member of a close circle of visionary poets and writers that included Lord Byron, John Keats, Leigh Hunt, Thomas Love Peacock and his own second wife, Mary Shelley (the author of ''Frankenstein'').
Shelley is best known for classic poems such as "Ozymandias", "Ode to the West Wind", "To a Skylark", "Music, When Soft Voices Die", "The Cloud" and ''The Masque of Anarchy''. His other major works include a groundbreaking verse drama, ''The Cenci'' (1819), and long, visionary, philosophical poems such as ''Queen Mab'' (later reworked as ''The Daemon of the World''), ''Alastor'', ''The Revolt of Islam'', ''Adonais'', ''Prometheus Unbound'' (1820)—widely considered his masterpiece—''Hellas: A Lyrical Drama'' (1821) and his final, unfinished work, ''The Triumph of Life'' (1822).
Shelley's close circle of friends included some of the most important progressive/radical thinkers of his day, including his father-in-law, the philosopher William Godwin (1756–1836), and Leigh Hunt (1784–1859). Though Shelley's poetry and prose output remained steady throughout his life, most publishers and journals declined to publish his work for fear of being arrested for either blasphemy or sedition. Shelley's poetry sometimes had only an underground readership during his day, but his poetic achievements have become widely recognized today, and his political and social thought had an impact on the Chartist and other movements in England, and reach down to the present day. Shelley's theories of economics and morality, for example, had a profound influence on Karl Marx (1818–1883); his early—perhaps first—writings on nonviolent resistance influenced Leo Tolstoy (1828–1910), whose writings on the subject in turn influenced Mahatma Gandhi, and through him Martin Luther King Jr. and others practicing nonviolence during the American civil rights movement.
Shelley became a lodestar to the subsequent three or four generations of poets, including important Victorian and Pre-Raphaelite poets such as Robert Browning (1812–1889) and Dante Gabriel Rossetti (1828–1882). Admirers have included Oscar Wilde, Thomas Hardy, George Bernard Shaw, Leo Tolstoy, Bertrand Russell, W. B. Yeats, Upton Sinclair and Isadora Duncan. Henry David Thoreau's ''Civil Disobedience'' (1849) apparently shows the influence of Shelley's writings and theories on nonviolence in protest and political action. Shelley's popularity and influence has continued to grow in contemporary poetry circles. Provided by Wikipedia
