Known for his lyrical and long-form verse, Percy Bysshe Shelley is one of the most highly regarded English Romantic poets of the 19th century. "A Defence of Poetry" is an essay by the English poet Percy Bysshe Shelley, written in 1821 and first published posthumously in 1840 in Essays, Letters from Abroad, Translations and Fragments by Edward Moxon in London. It contains Shelley's famous claim that "poets are the unacknowledged legislators of the world". In his short but successful career, Shelley gained appreciation from eminent persons such as Karl Marx, Henry Stephens Salt and from other contemporary authors as well including eminent poet and friend Lord Byron, so it will not leave you indifferent too.
