The Romantic Movement was a reaction against the formal style of 18th century poetry that occurred between 1789-1832. It focused on individual emotions and experiences over social rules, emphasizing themes of nature, childhood memories, and the supernatural in the works of writers like William Wordsworth, Lord Byron, Samuel Taylor Coleridge, Percy Bysshe Shelley, and Mary Shelley. The movement began as a reaction to the French Revolution and was influenced by French philosophers advocating liberty, equality, and fraternity.
