Symbolist theatre emerged in the late 19th century as a reaction against realistic drama. It sought to express inner truths through the use of symbols, myths, legends, and metaphors rather than literal representations of life. Symbolist plays had little plot action but took lyrical, poetic forms. Leading practitioners included Villiers de L'Isle-Adam and Maurice Maeterlinck, while the movement influenced later playwrights like Ibsen and Strindberg who incorporated its techniques. Symbolism aimed to depict inner thoughts and feelings indirectly through symbolic means.
