This study focuses on Percy Bysshe Shelley’s opposition to all kinds of authorities both in his life and in his works. This study gives an account of the effect of Shelley’s radical life on his works. The study first begins with some brief information about the poet’s life, then it will briefly focus on the Romanticism and Shelley’s contribution to Romanticism. After giving some information about above-mentioned issues, Shelley’s three poems, “Ozymandias”, “England in 1819” and “Ode to the West Wind” will be analyzed, because these poems reflect Shelley’s literary identity more significantly than his other works. Overall, these poems support the views of this study. Due to the practical constraints, this paper cannot provide a more comprehensive review of the poet’s other works.
