Romanticism in theatre emerged as a reaction to the Age of Enlightenment, emphasizing emotion and imagination over reason. This movement celebrated individuality, nature, and artistic freedom, rejecting classical conventions in favor of more expressive and passionate storytelling. Key figures like Goethe, Schiller, and Hugo pioneered romantic theatre, exploring themes of love, rebellion, and the supernatural. Their works featured elaborate staging, poetic language, and complex characters, influencing future generations of playwrights and shaping modern theatrical practices.
