Percy Bysshe Shelley (1792–1822) was a visionary English Romantic poet renowned for his radical political views and lyrical poetry. Born into an influential family, he attended Eton and briefly Oxford before being expelled for his atheist views. Shelley championed social reform, freedom, and the power of imagination, themes evident in works like "Ozymandias," "To a Skylark," and "Prometheus Unbound." He formed a close alliance with fellow poet Lord Byron and married renowned author Mary Shelley. Shelley's life was marked by controversy and exile, but his poignant exploration of nature, love, and human spirit left an indelible impact on literature.
