Percy Florence Shelley Bysshe Shelley, his namesake, and his wife author Mary Shelley. His elder siblings, consisting of a premature girl who died at few weeks old and a brother and a sister who died in childhood left him as the only surviving child as his mother suffered a miscarriage in 1822. His parents lived in Italy for several years, until his father drowned off Livorno, whereupon his mother moved back to England with him. Mary Shelley never remarried; Percy Florence had no further siblings. He joined Harrow School in 1832, and went up to Trinity College, Cambridge in October 1837. Shelley inherited
Percy Bysshe Shelley theories of economics and morality, for example, had a profound influence on Karl Marx; his early—perhaps first—writings on nonviolent resistance influenced Leo Tolstoy, 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 lodestone to the subsequent three or four generations of poets, including important Victorian and Pre-Raphaelite poets such as Robert Browning and Dante Gabriel Rossetti. He was admired by Oscar Wilde, Thomas Hardy, George Bernard Shaw, Leo Tolstoy, Bertrand Russell, W. B. Yeats, Upton Sinclair and Isadora Duncan.
