Symbolism was a literary movement that began in 1886 as a reaction against rigid French poetry. It aimed to use symbols to represent ideas and emotions rather than directly expressing them. Key features included obscure references open to multiple interpretations, repetition for suggestive effect, and using colors and language figuratively rather than literally. Major symbolist poets were Wallace Stevens, T.S. Eliot, Ezra Pound, and W.B. Yeats. The movement sought to express the subconscious and blend perceptions in a way that moved fluidly between objective and subjective experience.
