"A Defence of Poetry" is an unfinished essay by Percy Bysshe Shelley written in February and March 1821 that the poet put aside and never completed.[1] The text was published posthumously in 1840 in Essays, Letters from Abroad, Translations and Fragments.[2] Its final sentence expresses Shelley's famous proposition that "poets are the unacknowledged legislators of the world."
