Shelley was born in Horsham, Sussex, England, to a wealthy family. He began writing poetry at a young age, and his first published poem, "Original Poetry by Victor and Cazire," was published when he was just 18 years old. In 1811, he was expelled from Oxford University for publishing a pamphlet entitled "The Necessity of Atheism."
Shelley's political views were radical and often controversial. He was a supporter of the French Revolution, and he believed in the power of poetry to effect social change. In his poetry, he expressed his opposition to tyranny and oppression, and he called for a more egalitarian society.
Shelley's most famous poems include "Ozymandias," "Ode to the West Wind," "To a Skylark," and "Prometheus Unbound." His plays include "The Cenci," "Prometheus Unbound," and "Hellas."
Shelley's life was tragically cut short when he drowned in a storm in the Gulf of Spezia in Italy at the age of 29. He is buried in the Protestant Cemetery in Rome, Italy.
Despite his short life, Shelley is considered one of the most important poets of the Romantic movement. His work has been praised for its beauty, passion, and idealism, and it continues to be read and enjoyed by readers around the world.
