Percy Bysshe Shelley, (born Aug. 4, 1792, Field Place, near Horsham, Sussex, Eng.—died July 8, 1822, at sea off Livorno, Tuscany [Italy]), English Romantic poet whose passionate search for personal love and social justice was gradually channeled from overt actions into poems that rank with the greatest in the English language.

Shelley was the heir to rich estates acquired by his grandfather, Bysshe (pronounced “Bish”) Shelley. Timothy Shelley, the poet’s father, was a weak, conventional man who was caught between an overbearing father and a rebellious son. The young Shelley was educated at Syon House Academy (1802–04) and then at Eton (1804–10), where he resisted physical and mental bullying by indulging in imaginative escapism and literary pranks. Between the spring of 1810 and that of 1811, he published two Gothic novels and two volumes of juvenile verse. In the fall of 1810 Shelley entered University College, Oxford, where he enlisted his fellow student Thomas Jefferson Hogg as a disciple. But in March 1811, University College expelled both Shelley and Hogg for refusing to admit Shelley’s authorship of The Necessity of Atheism. Hogg submitted to his family, but Shelley refused to apologize to his.

Late in August 1811, Shelley eloped with Harriet Westbrook, the younger daughter of a London tavern owner; by marrying her, he betrayed the acquisitive plans of his grandfather and father, who tried to starve him into submission but only drove the strong-willed youth to rebel against the established order. Early in 1812, Shelley, Harriet, and her older sister Eliza Westbrook went to Dublin, where Shelley circulated pamphlets advocating political rights for Roman Catholics, autonomy for Ireland, and freethinking ideals. The couple traveled to Lynmouth, Devon, where Shelley issued more political pamphlets, and then to North Wales, where they spent almost six months in 1812–13.

Lack of money finally drove Shelley to moneylenders in London, where in 1813 he issued Queen Mab, his first major poem—a nine-canto mixture of blank verse and lyric measures that attacks the evils of the past and present (commerce, war, the eating of meat, the church, monarchy, and marriage) but ends with resplendent hopes for humanity when freed from these vices. In June 1813 Harriet Shelley gave birth to their daughter Ianthe, but a year later Shelley fell in love with Mary Wollstonecraft Godwin, daughter of William Godwin and his first wife, née Mary Wollstonecraft. Against Godwin’s objections, Shelley and Mary Godwin eloped to France on July 27, 1814, taking with them Mary’s stepsister Jane (later “Claire”) Clairmont. Following travels through France, Switzerland, and Germany, they returned to London, where they were shunned by the Godwins and most other friends. Shelley dodged creditors until the birth of his son Charles (born to Harriet, November 30, 1814), his grandfather’s death (January 1815), and provisions of Sir Bysshe’s will forced Sir Timothy to pay Shelley’s debts and grant him an annual income.
